Raw Blame History

v5.10.0 (2018-05-10):

AUDIT SHOULDN'T WAIT FOREVER

This will likely be reduced further with the goal that the audit process shouldn't noticibly slow down your builds regardless of your network situation.

v5.10.0-next.1 (2018-05-07):

EXTENDED npm init SCAFFOLDING

Thanks to the wonderful efforts of @jdalton of lodash fame, npm init can now be used to invoke custom scaffolding tools!

You can now do things like npm init react-app or npm init esm to scaffold an npm package by running create-react-app and create-esm, respectively. This also adds an npm create alias, to correspond to Yarn's yarn create feature, which inspired this.

DEPENDENCY AUDITING

This version of npm adds a new command, npm audit, which will run a security audit of your project's dependency tree and notify you about any actions you may need to take.

The registry-side services required for this command to work will be available on the main npm registry in the coming weeks. Until then, you won't get much out of trying to use this on the CLI.

As part of this change, the npm CLI now sends scrubbed and cryptographically anonymized metadata about your dependency tree to your configured registry, to allow notifying you about the existence of critical security flaws. For details about how the CLI protects your privacy when it shares this metadata, see npm help audit, or read the docs for npm audit online. You can disable this altogether by doing npm config set audit false, but will no longer benefit from the service.

CTRL-C OUT DURING PACKAGE EXTRACTION AS MUCH AS YOU WANT!

SHRONKWRAPS AND LACKFILES

If a published modules had legacy npm-shrinkwrap.json we were saving ordinary registry dependencies (name@version) to your package-lock.json as https:// URLs instead of versions.

  • 36f998411 When saving the lock-file compute how the dependency is being required instead of using _resolved in the package.json. This fixes the bug that was converting registry dependencies into https:// dependencies. (@iarna)
  • 113e1a3af When encountering a https:// URL in our lockfiles that point at our default registry, extract the version and use them as registry dependencies. This lets us heal package-lock.json files produced by 6.0.0 (@iarna)

MORE package-lock.json FORMAT CHANGES?!

  • 074502916 #20384 Add from field back into package-lock for git dependencies. This will give npm the information it needs to figure out whether git deps are valid, specially when running with legacy install metadata or in --package-lock-only mode when there's no node_modules. This should help remove a significant amount of git-related churn on the lock-file. (@zkat)

DOCUMENTATION IMPROVEMENTS

BUGFIXES

  • 268f7ac50 5f84ebdb6 c12e61431 #20390 Fix a scenario where a git dependency had a comittish associated with it that was not a complete commitid. npm would never consider that entry in the package.json as matching the entry in the package-lock.json and this resulted in inappropriate pruning or reinstallation of git dependencies. This has been addressed in two ways, first, the addition of the from field as described in #20384 means we can exactly match the package.json. Second, when that's missing (when working with older package-lock.json files), we assume that the match is ok. (If it's not, we'll fix it up when a real installation is done.) (@iarna)

DEPENDENCY UPDATES

v5.10.0-next.0 (2018-04-12):

NEW FEATURES

BUG FIXES

  • 089aeaf44 Fix a bug where OTPs passed in via the commandline would have leading zeros deleted resulted in authentication failures. (@iarna)

  • 6eaa860ea Eliminate direct use of new Buffer in npm. While the use of it in npm was safe, there are two other reasons for this change:

    1. Node 10 emits warnings about its use.
    2. Users who require npm as a library (which they definitely should not do) can call the functions that call new Buffer in unsafe ways, if they try really hard.

    (@iarna)

  • 85900a294 Starting with 5.8.0 the requires section of the lock-file saved version ranges instead of specific versions. Due to a bug, further actions on the same lock-file would result in the range being switched back to a version. This corrects that, keeping ranges when they appear. (@iarna)

  • 0dffa9c2a 609d6f6e1 08f81aa94 f8b76e076 6d609822d 59d080a22 Restore the ability to bundle dependencies that are uninstallable from the registry. This also eliminates needless registry lookups for bundled dependencies.

    Fixed a bug where attempting to install a dependency that is bundled inside another module without reinstalling that module would result in ENOENT errors. (@iarna)

  • db846c2d5 #20029 Allow packages with non-registry specifiers to follow the fast path that the we use with the lock-file for registry specifiers. This will improve install time especially when operating only on the package-lock (--package-lock-only).

    (@zkat)

    Fix the a bug where npm i --only=prod could remove development dependencies from lock-file. (@iarna)

  • 3e12d2407 #20122 Improve the update-notifier messaging (borrowing ideas from pnpm) and eliminate false positives. (@zkat)

  • f18be9b39 #20154 Let version succeed when package-lock.json is gitignored. (@nwoltman)

  • ced29253d #20212 Ensure that we only create an etc directory if we are actually going to write files to it. (@buddydvd)

  • 8e21b19a8 #20140 Note in documentation that package-lock.json version gets touched by npm version. (@srl295)

  • 5d17c87d8 #20032 Fix bug where unauthenticated errors would get reported as both 404s and 401s, i.e. npm ERR! 404 Registry returned 401. In these cases the error message will now be much more informative. (@iarna)

  • 05ff6c9b1 #20082 Allow optional @ prefix on scope with npm team commands for parity with other commands. (@bcoe)

  • 6bef53891 #19580 Improve messaging when two-factor authentication is required while publishing. (@jdeniau)

  • 155dab2bd Fix a bug where optional status of a dependency was not being saved to the package-lock on the initial install. (@iarna)

  • 8d6a4cafc a0937e9af Ensure that --no-optional does not remove optional dependencies from the lock-file. (@iarna)

DEPENDENCY UPDATES

v5.9.0 (2018-03-23):

Coming to you this week are a fancy new package view, pack/publish previews and a handful of bug fixes! Let's get right in!

NEW PACKAGE VIEW

There's a new npm view in town. You might it as npm info or npm show. The new output gives you a nicely summarized view that for most packages fits on one screen. If you ask it for --json you'll still get the same results, so your scripts should still work fine.

PACK AND PUBLISH PREVIEWS

The npm pack and npm publish commands print out a summary of the files included in the package. They also both now take the --dry-run flag, so you can double check your .npmignore settings before doing a publish.

  • 116e9d827 #19908 Add package previews to pack and publish. Also add --dry-run and --json flags. (@zkat)

MERGE CONFLICT, SMERGE CONFLICT

If you resolve a package-lock.json merge conflict with npm install we now suggest you setup a merge driver to handle these automatically for you. If you're reading this and you'd like to set it up now, run:

npx npm-merge-driver install -g

MISC BITS

  • a05e27b71 Going forward, record requested ranges not versions in the package-lock. (@iarna)
  • f721eec59 Add 10 to Node.js supported version list. It's not out yet, but soon my pretties... (@iarna)

DEPENDENCY UPDATES

v5.8.0 (2018-03-08):

Hey again, everyone! While last release was focused largely around PRs from the CLI team, this release is mostly pulling in community PRs in npm itself and its dependencies! We've got a good chunk of wonderful contributions for y'all, and even new features and performance improvements! 🎉

We're hoping to continue our biweekly (as in every-other-week biweekly) release schedule from now on, so you should be seeing more steady npm releases from here on out. And that's good, 'cause we've got a ton of new stuff on our roadmap for this year. Keep an eye out for exciting news. 👀

FEATURES

  • 2f513fe1c #19904 Make a best-attempt at preserving line ending style when saving package.json/package-lock.json/npm-shrinkwrap.json. This goes hand-in-hand with a previous patch to preserve detected indentation style. (@tuananh)
  • d3cfd41a2 pacote@7.6.1 (@zkat)
    • Enable file:-based resolved URIs in package-lock.json.
    • Retry git-based operations on certain types of failure.
  • ecfbb16dc #19929 Add support for the NO_COLOR standard. This gives a cross-application, consistent way of disabling ANSI color code output. Note that npm already supported this through --no-color or npm_config_color='false' configurations, so this is just another way to do it. (@chneukirchen)
  • fc8761daf #19629 Give more detailed, contextual information when npm fails to parse package-lock.json and npm-shrinkwrap.json, instead of saying JSON parse error and leaving you out in the cold. (@JoshuaKGoldberg)
  • 1d368e1e6 #19157 Add --no-proxy config option. Previously, you needed to use the NO_PROXY environment variable to use this feature -- now it's an actual npm option. (@Saturate)
  • f0e998daa #18426 Do environment variable replacement in config files even for config keys or fragments of keys. (@misak113)
  • 9847c82a8 #18384 Better error messaging and suggestions when users get EPERM/EACCES errors. (@chrisjpatty)
  • b9d0c0c01 #19448 Holiday celebrations now include all JavaScripters, not just Node developers. (@isaacs)

NPM CI

I hope y'all have been having fun with npm ci so far! Since this is the first release since that went out, we've had a few fixes and improvements now that folks have actually gotten their hands on it! Benchmarks have been super promising so far, and I've gotten messages from a lot of you saying you've sped up your CI work by 2-5x in some cases! Have a good example? Tell us on Twitter!

npm ci is, right now, the fastest installer you can use in CI situations, so go check it out if you haven't already! We'll continue doing performance improvements on it, and a lot of those will help make npm install fast as well. 🏎😎

This libcipm release includes a number of improvements:

  • PERFORMANCE Reduce calls to read-package-json and separate JSON update phase from man/bin linking phase. npm ci should be noticeably faster.
  • FEATURE Progress bar now fills up as packages are installed, instead of sitting there doing nothing.
  • BUGFIX Add support for --only and --also options.
  • BUFGIX Linking binaries and running scripts in parallel was causing packages to sometimes clobber each other when hoisted, as well as potentially running too many run-scripts in parallel. This is now a serial operation, and it turns out to have had relatively little actual performance impact.
  • BUGFIX Stop adding _from to directory deps (aka file:packages/my-dep).

BUGFIXES

  • 58d2aa58d #20027 Use a specific mtime when packing tarballs instead of the beginning of epoch time. This should allow npm pack to generate tarballs with identical hashes for identical contents, while fixing issues with some zip implementations that do not support pre-1980 timestamps. (@isaacs)
  • 4f319de1d Don't fall back to couch adduser if we didn't try couch login. (@iarna)
  • c8230c9bb #19608 Fix issue where using the npm-bundled npx on Windows was invoking npx prefix (and downloading that package). (@laggingreflex)
  • d70c01970 #18953 Avoid using code that depends on node@>=4 in the unsupported check, so npm can report the issue normally instead of syntax-crashing. (@deployable)

DOCUMENTATION

MISC

  • b8a48a959 #19907 Consolidate code for stringifying package.json and package locks. Also adds tests have been added to test that package[-lock].json files are written to disk with their original line endings. (@nwoltman)
  • b4f707d9f #19879 Remove unused devDependency nock from .gitignore. (@watilde)
  • 8150dd5f7 #16540 Stop doing an uninstall when using make clean. (@metux)

OTHER DEPENDENCY BUMPS

v5.7.1 (2018-02-22):

This release reverts a patch that could cause some ownership changes on system files when running from some directories when also using sudo. 😲

Thankfully, it only affected users running npm@next, which is part of our staggered release system, which we use to prevent issues like this from going out into the wider world before we can catch them. Users on latest would have never seen this!

The original patch was added to increase consistency and reliability of methods npm uses to avoid writing files as root in places it shouldn't, but the change was applied in places that should have used regular mkdirp. This release reverts that patch.

v5.7.0 (2018-02-20):

Hey y'all, it's been a while. Expect our release rate to increase back to normal here, as we've got a lot in the pipeline. Right now we've got a bunch of things from folks at npm. In the next release we'll be focusing on user contributions and there are a lot of them queued up!

This release brings a bunch of exciting new features and bug fixes.

PACKAGE-LOCK GIT MERGE CONFLICT RESOLUTION

Allow npm install to fix package-lock.json and npm-shrinkwrap.json files that have merge conflicts in them without your having to edit them. It works in conjunction with npm-merge-driver to entirely eliminate package-lock merge conflicts.

  • e27674c22 Automatically resolve merge conflicts in lock-files. (@zkat)

NPM CI

The new npm ci command installs from your lock-file ONLY. If your package.json and your lock-file are out of sync then it will report an error.

It works by throwing away your node_modules and recreating it from scratch.

Beyond guaranteeing you that you'll only get what is in your lock-file it's also much faster (2x-10x!) than npm install when you don't start with a node_modules.

As you may take from the name, we expect it to be a big boon to continuous integration environments. We also expect that folks who do production deploys from git tags will see major gains.

OTHER NEW FEATURES

BIG FIXES TO PRUNING

  • 827951590 Handle running npm install package-name with a node_modules containing packages without sufficient metadata to verify their origin. The only way to get install packages like this is to use a non-npm package manager. Previously npm removed any packages that it couldn't verify. Now it will leave them untouched as long as you're not asking for a full install. On a full install they will be reinstalled (but the same versions will be maintained).

    This will fix problems for folks who are using a third party package manager to install packages that have postinstall scripts that run npm install. (@iarna)

  • 3b305ee71 Only auto-prune on installs that will create a lock-file. This restores npm@4 compatible behavior when the lock-file is disabled. When using a lock-file npm will continue to remove anything in your node_modules that's not in your lock-file. (@iarna)

  • cec5be542 Fix bug where npm prune --production would remove dev deps from the lock file. It will now only remove them from node_modules not from your lock file. (@iarna)

  • 857dab03f Fix bug where git dependencies would be removed or reinstalled when installing other dependencies. (@iarna)

BUG FIXES TO TOKENS AND PROFILES

  • a66e0cd03 For CIDR filtered tokens, allow comma separated CIDR ranges, as documented. Previously you could only pass in multiple cidr ranges with multiple --cidr command line options. (@iarna)
  • d259ab014 Fix token revocation when an OTP is required. Previously you had to pass it in via --otp. Now it will prompt you for an OTP like other npm token commands. (@iarna)
  • f8b1f6aec Update token and profile commands to support legacy (username/password) authentication. (The npm registry uses tokens, not username/password pairs, to authenticate commands.) (@iarna)

OTHER BUG FIXES

  • 6954dfc19 Fix a bug where packages would get pushed deeper into the tree when upgrading without an existing copy on disk. Having packages deeper in the tree ordinarily is harmless but is not when peerDependencies are in play. (@iarna)
  • 1ca916a1e Fix bug where when switching from a linked module to a non-linked module, the dependencies of the module wouldn't be installed on the first run of npm install. (@iarna)
  • 8c120ebb2 Fix integrity matching to eliminate spurious EINTEGRITY errors. (@zkat)
  • 94227e15e More consistently make directories using perm and ownership preserving features. (@iarna)

DEPENDENCY UPDATES

v5.6.0 (2017-11-27):

Features!

You may have noticed this is a semver-minor bump. Wondering why? This is why!

  • bc263c3fd #19054 Fully cross-platform package-lock.json. Installing a failing optional dependency on one platform no longer removes it from the dependency tree, meaning that package-lock.json should now be generated consistently across platforms! 🎉 (@iarna)
  • f94fcbc50 #19160 Add --package-lock-only config option. This makes it so you can generate a target package-lock.json without performing a full install of node_modules. (@alopezsanchez)
  • 66d18280c #19104 Add new --node-options config to pass through a custom NODE_OPTIONS for lifecycle scripts. (@bmeck)
  • 114d518c7 Ignore mtime when packing tarballs: This means that doing npm pack on the same repository should yield two tarballs with the same checksum. This will also help prevent cache bloat when using git dependencies. In the future, this will allow npm to explicitly cache git dependencies. (@isaacs)

Node 9

Previously, it turns out npm broke on the latest Node, node@9. We went ahead and fixed it up so y'all should be able to use the latest npm again!

Bug Fixes

  • b70321733 #18881 When dealing with a node_modules that was created with older versions of npm (and thus older versions of npa) we need to gracefully handle older spec entries. Failing to do so results in us treating those packages as if they were http remote deps, which results in invalid lock files with version set to tarball URLs. This should now be fixed. (@iarna)
  • 2f9c5dd00 #18880 Stop overwriting version in package data on disk. This is another safeguard against the version overwriting that's plagued some folks upgrading from older package-locks. (@iarna) (@joshclow)
  • a93e0a51d #18846 Correctly save transitive dependencies when using npm update in package-lock.json. (@iarna)
  • fdde7b649 #18825 Fix typo and concatenation in error handling. (@alulsh)
  • be67de7b9 #18711 Upgrade to bearer tokens from legacy auth when enabling 2FA. (@iarna)
  • bfdf0fd39 #19033 Fix issue where files with @ signs in their names would not get included when packing tarballs. (@zkat)
  • b65b89bde #19048 Fix problem where npm login was ignoring various networking-related options, such as custom certs. (@wejendorp)
  • 8c194b86e npm-packlist@1.1.10: Include node_modules/ directories not in the root. (@isaacs)
  • d7ef6a20b libnpx@9.7.1: Fix some *nix binary path escaping issues. (@zkat)
  • 981828466 cacache@10.0.1: Fix fallback to copy-concurrently when file move fails. This might fix permissions and such issues on platforms that were getting weird filesystem errors during install. (@karolba)
  • a0be6bafb pacote@7.0.2: Includes a bunch of fixes, specially for issues around git dependencies. Shasum-related errors should be way less common now, too. (@zkat)
  • b80d650de #19163 Fix a number of git and tarball specs and checksum errors. (@zkat)
  • cac225025 #19054 Don't count failed optionals when summarizing installed packages. (@iarna)

UX

  • b1ec2885c #18326 Stop truncating output of npm view. This means, for example, that you no longer need to use --json when a package has a lot of versions, to see the whole list. (@SimenB)
  • 55a124e0a #18884 Profile UX improvements: better messaging on unexpected responses, and stop claiming we set passwords to null when resetting them. (@iarna)
  • 635481c61 #18844 Improve error messaging for OTP/2FA. (@iarna)
  • 52b142ed5 #19054 Stop running the same rollback multiple times. This should address issues where Windows users saw strange failures when fsevents failed to install. (@iarna)
  • 798428b0b #19172 bin-links@1.1.0: Log the fact line endings are being changed upon install. (@marcosscriven)

Refactors

Usually, we don't include internal refactor stuff in our release notes, but it's worth calling out some of them because they're part of a larger effort the CLI team and associates are undertaking to modularize npm itself so other package managers and associated tools can reuse all that code!

  • 9d22c96b7 #18500 Extract bin-links and gentle-fs to a separate library. This will allow external tools to do bin linking and certain fs operations in an npm-compatible way! (@mikesherov)
  • 015a7803b #18883 Capture logging from log events on the process global. This allows npm to use npmlog to report logging from external libraries like npm-profile. (@iarna)
  • c930e98ad npm-lifecycle@2.0.0: Use our own node-gyp. This means npm no longer needs to pull some maneuvers to make sure node-gyp is in the right place, and that external packages using npm-lifecycle will get working native builds without having to do their own node-gyp maneuvers. (@zkochan)
  • 876f0c8f3 829893d61 #19099 find-npm-prefix@1.0.1: npm's prefix-finding logic is now a standalone module. That is, the logic that figures out where the root of your project is if you've cd'd into a subdirectory. Did you know you can run npm install from these subdirectories, and it'll only affect the root? It works like git! (@iarna)

Dependency Bumps

v5.5.1 (2017-10-04):

A very quick, record time, patch release, of a bug fix to a (sigh) last minute bug fix.

  • e628e058b Fix login to properly recognize OTP request and store bearer tokens. (@iarna)

v5.5.0 (2017-10-04):

Hey y'all, this is a big new feature release! We've got some security related goodies plus a some quality-of-life improvements for anyone who uses the public registry (so, virtually everyone).

The changes largely came together in one piece, so I'm just gonna leave the commit line here:

TWO FACTOR AUTHENTICATION

You can now enable two-factor authentication for your npm account. You can even do it from the CLI. In fact, you have to, for the time being:

npm profile enable-tfa

With the default two-factor authentication mode you'll be prompted to enter a one-time password when logging in, when publishing and when modifying access rights to your modules.

TOKEN MANAGEMENT

You can now create, list and delete authentication tokens from the comfort of the command line. Authentication tokens created this way can have NEW restrictions placed on them. For instance, you can create a read-only token to give to your CI. It will be able to download your private modules but it won't be able to publish or modify modules. You can also create tokens that can only be used from certain network addresses. This way you can lock down access to your corporate VPN or other trusted machines.

Deleting tokens isn't new, you could do it via the website but now you can do it via the CLI as well.

CHANGE YOUR PASSWORD, SET YOUR EMAIL

You can finally change your password from the CLI with npm profile set password! You can also update your email address with npm profile set email <address>. If you change your email address we'll send you a new verification email so you verify that its yours.

AND EVERYTHING ELSE ON YOUR PROFILE

You can also update all of the other attributes of your profile that previously you could only update via the website: fullname, homepage, freenode, twitter and github.

AVAILABLE STAND ALONE

All of these features were implemented in a stand alone library, so if you have use for them in your own project you can find them in npm-profile on the registry. There's also a little mini-cli written just for it at npm-profile-cli. You might also be interested in the API documentation for these new features: user profile editing and authentication.

BUG FIXES

  • 5ee55dc71 install.sh: Drop support for upgrading from npm@1 as npm@5 can't run on any Node.js version that ships npm@1. This fixes an issue some folks were seeing when trying to upgrade using curl | http://npmjs.com/install.sh. (@iarna)
  • 5cad1699a npm-lifecycle@1.0.3 Fix a bug where when more than one lifecycle script got queued to run, npm would crash. (@zkat)
  • cd256cbb2 npm-packlist@1.1.9 Fix a bug where test directories would always be excluded from published modules. (@isaacs)
  • 2a11f0215 Fix formatting of unsupported version warning (@iarna)

DEPENDENCY UPDATES

  • 6d2a285a5 npm-registry-client@8.5.0
  • 69e64e27b request@2.83.0
  • 34e0f4209 abbrev@1.1.1
  • 10d31739d aproba@1.2.0
  • 2b02e86c0 meant@1.0.1
  • b81fff808 rimraf@2.6.2: Fixes a long standing bug in rimraf's attempts to work around Windows limitations where it owns a file and can change its perms but can't remove it without first changing its perms. This may be an improvement for Windows users of npm under some circumstances. (@isaacs)

v5.4.2 (2017-09-14):

This is a small bug fix release wrapping up most of the issues introduced with 5.4.0.

Bugs

  • 0b28ac72d #18458 Fix a bug on Windows where rolling back of failed optional dependencies would fail. (@marcins)
  • 3a1b29991 write-file-atomic@2.1.0 Revert update of write-file-atomic. There were changes made to it that were resulting in EACCES errors for many users. (@iarna)
  • cd8687e12 Fix a bug where if npm decided it needed to move a module during an upgrade it would strip out much of the package.json. This would result in broken trees after package updates.
  • 5bd0244ee #18385 Fix npm outdated when run on non-registry dependencies. (@joshclow) (@iarna)

Ux

  • 339f17b1e Report unsupported node versions with greater granularity. (@iarna)

Docs

v5.4.1 (2017-09-06):

This is a very small bug fix release to fix a problem where permissions on installed binaries were being set incorrectly.

v5.4.0 (2017-08-22):

Here's another small big release, with a handful bunch of fixes and a couple of small new features! This release has been incubating rather longer than usual and it's grown quite a bit in that time. I'm also excited to say that it has contributions from 27 different folks, which is a new record for us. Our previous record was 5.1.0 at 21.

If you can't get enough of the bleeding edge, I encourage you to check out our canary release of npm. Get it with npm install -g npmc. It's going to be seeing some exciting stuff in the next couple of weeks, starting with a rewritten npm dedupe, but moving on to… well, you'll just have to wait and find out.

PERFORMANCE

  • d080379f6 pacote@6.0.1 Updates extract to use tar@4, which is much faster than the older tar@2. It reduces install times by as much as 10%. (@zkat)
  • 4cd6a1774 0195c0a8c #16804 tar@4.0.1 Update publish to use tar@4. tar@4 brings many advantages over tar@2: It's faster, better tested and easier to work with. It also produces exactly the same byte-for-byte output when producing tarballs from the same set of files. This will have some nice carry on effects for things like caching builds from git. And finally, last but certainly not least, upgrading to it also let's us finally eliminate fstream—if you know what that is you'll know why we're so relieved. (@isaacs)

FEATURES

  • 1ac470dd2 #10382 If you make a typo when writing a command now, npm will print a brief "did you mean..." message with some possible alternatives to what you meant. (@watilde)
  • 20c46228d #12356 When running lifecycle scripts, INIT_CWD will now contain the original working directory that npm was executed from. Remember that you can use npm run-script even if you're not inside your package root directory! (@MichaelQQ)
  • be91e1726 4e7c41f4a libnpx@9.6.0: Fixes a number of issues on Windows and adds support for several more languages: Korean, Norwegian (bokmål and nynorsk), Ukrainian, Serbian, Bahasa Indonesia, Polish, Dutch and Arabic. (@zkat)
  • 2dec601c6 #17142 Add the new commit-hooks option to npm version so that you can disable commit hooks when committing the version bump. (@faazshift)
  • bde151902 #14461 Make output from npm ping clear as to its success or failure. (@legodude17)

BUGFIXES

  • b6d5549d2 #17844 Make package-lock.json sorting locale-agnostic. Previously, sorting would vary by locale, due to using localeCompare for key sorting. This'll give you a little package-lock.json churn as it reshuffles things, sorry! (@LotharSee)
  • 44b98b9dd #17919 Fix a crash where npm prune --production would fail while removing .bin. (@fasterthanlime)
  • c3d1d3ba8 #17816 Fail more smoothly when attempting to install an invalid package name. (@SamuelMarks)
  • 55ac2fca8 #12784 Guard against stack overflows when marking packages as failed. (@vtravieso)

  • 7a7710ba7 #15088 Don't exclude modules that are both dev & prod when using npm ls --production. (@iarna)
  • 867df2b02 #18164 Only do multiple procs on OSX for now. We've seen a handful of issues relating to this in Docker and in on Windows with antivirus. (@zkat)
  • 23540af7b #18117 Some package managers would write spaces to the _from field in package.json's in the form of name @spec. This was causing npm to fail to interpret them. We now handle that correctly and doubly make sure we don't do that ourselves. (@IgorNadj)
  • 0ef320cb4 #16634 Convert any bin script with a shbang a the start to Unix line-endings. (These sorts of scripts are not compatible with Windows line-endings even on Windows.) (@ScottFreeCode)
  • 71191ca22 #16476 npm-lifecycle@1.0.2 Running an install with --ignore-scripts was resulting in the the package object being mutated to have the lifecycle scripts removed from it and that in turn was being written out to disk, causing further problems. This fixes that: No more mutation, no more unexpected changes. (@addaleax)
  • 459fa9d51 npm/read-package-json#74 #17802 read-package-json@2.0.1 Use unix-style slashes for generated bin entries, which lets them be cross platform even when produced on Windows. (@iarna)
  • 5ec72ab5b #18229 Make install.sh find nodejs on debian. (@cebe)

  • ee4c9bd8a #16474 The tests in test/tap/lifecycle-signal.js, as well as the features they are testing, are partially broken. This moves them from being skipped in CI to being disabled only for certain platforms. In particular, because npm spawns its lifecycle scripts in a shell, signals are not necessarily forwarded by the shell and won’t cause scripts to exit; also, shells may report the signal they receive using their exit status, rather than terminating themselves with a signal.

v5.3.0 (2017-07-12):

As mentioned before, we're continuing to do relatively rapid, smaller releases as we keep working on stomping out npm@5 issues! We've made a lot of progress since 5.0 already, and this release is no exception.

FEATURES

  • 1e3a46944 #17616 Add --link filter option to npm ls. (@richardsimko)
  • 33df0aaa libnpx@9.2.0:
    • 4 new languages - Czech, Italian, Turkish, and Chinese (Traditional)! This means npx is available in 14 different languages!
    • New --node-arg option lets you pass CLI arguments directly to node when the target binary is found to be a Node.js script. (@zkat)

BUGFIXES

  • 33df0aaa libnpx@9.2.0:
    • npx should now work on (most) Windows installs. A couple of issues remain.
    • Prevent auto-fallback from going into an infinite loop when npx disappears.
    • npx npx npx npx npx npx npx npx works again.
    • update-notifier will no longer run for the npx bundled with npm.
    • npx <cmd> in a subdirectory of your project should be able to find your node_modules/.bin now. Oops (@zkat)
  • 8e979bf80 Revert change where npm stopped flattening modules that required peerDeps. This caused problems because folks were using peer deps to indicate that the target of the peer dep needed to be able to require the dependency and had been relying on the fact that peer deps didn't change the shape of the tree (as of npm@3). The fix that will actually work for people is for a peer dep to insist on never being installed deeper than the the thing it relies on. At the moment this is tricky because the thing the peer dep relies on may not yet have been added to the tree, so we don't know where it is. (@iarna)
  • 7f28a77f3 #17733 Split remove and unbuild actions into two to get uninstall lifecycles and the removal of transitive symlinks during uninstallation to run in the right order. (@iarna)
  • 637f2548f #17748 When rolling back use symlink project-relative path, fixing some issues with fs-vacuum getting confused while removing symlinked things. (@iarna)
  • f153b5b22 #17706 Use semver to compare node versions in npm doctor instead of plain > comparison. (@leo-shopify)
  • 542f7561 #17742 Fix issue where npm version would sometimes not commit package-locks. (@markpeterfejes)
  • 51a9e63d #17777 Fix bug exposed by other bugfixes where the wrong package would be removed. (@iarna)

DOCUMENTATION

Have we mentioned we really like documentation patches? Keep sending them in! Small patches are just fine, and they're a great way to get started contributing to npm!

v5.2.0 (2017-07-05):

It's only been a couple of days but we've got some bug fixes we wanted to get out to you all. We also believe that npx is ready to be bundled with npm, which we're really excited about!

npx!!!

npx is a tool intended to help round out the experience of using packages from the npm registry — the same way npm makes it super easy to install and manage dependencies hosted on the registry, npx is meant to make it easy to use CLI tools and other executables hosted on the registry. It greatly simplifies a number of things that, until now, required a bit of ceremony to do with plain npm.

@zkat has a great introduction post to npx that I highly recommend you give a read

BUG FIXES

  • 9fe905c39 #17652 Fix max callstack exceeded loops with trees with circular links. (@iarna)
  • c0a289b1b #17606 Make sure that when write package.json and package-lock.json we always use unix path separators. (@Standard8)
  • 1658b79ca #17654 Make npm outdated show results for globals again. Previously it never thought they were out of date. (@iarna)
  • 06c154fd6 #17678 Stop flattening modules that have peer dependencies. We're making this change to support scenarios where the module requiring a peer dependency is flattened but the peer dependency itself is not, due to conflicts. In those cases the module requiring the peer dep can't be flattened past the location its peer dep was placed in. This initial fix is naive, never flattening peer deps, and we can look into doing something more sophisticated later on. (@iarna)
  • 88aafee8b #17677 There was an issue where updating a flattened dependency would sometimes unflatten it. This only happened when the dependency had dependencies that in turn required the original dependency. (@iarna)
  • b58ec8eab #17626 Integrators who were building their own copies of npm ran into issues because make install and https://npmjs.com/install.sh weren't aware that npm install creates links now when given a directory to work on. This does not impact folks installing npm with npm install -g npm. (@iarna)

DOC FIXES

v5.1.0 (2017-07-05):

Hey y'all~

We've got some goodies for you here, including npm@5's first semver-minor release! This version includes a huge number of fixes, particularly for some of the critical bugs users were running into after upgrading npm. You should overall see a much more stable experience, and we're going to continue hacking on fixes for the time being. Semver-major releases, specially for tools like npm, are bound to cause some instability, and getting npm@5 stable is the CLI team's top priority for now!

Not that bugfixes are the only things that landed, either: between improvements that fell out of the bugfixes, and some really cool work by community members like @mikesherov, npm@5.1.0 is twice as fast as npm@5.0.0 in some benchmarks. We're not stopping there, either: you can expect a steady stream of speed improvements over the course of the year. It's not top priority, but we'll keep doing what we can to make sure npm saves its users as much time as possible.

Hang on to your seats. At 100 commits, this release is a bit of a doozy. 😎

FEATURES

Semver-minor releases, of course, mean that there's a new feature somewhere, right? Here's what's bumping that number for us this time:

  • a09c1a69d #16687 Allow customizing the shell used to execute run-scripts. (@mmkal)
  • 4f45ba222 a48958598 901bef0e1 #17508 Add a new requires field to package-lock.json with information about the logical dependency tree. This includes references to the specific version each package is intended to see, and can be used for many things, such as converting package-lock.json to other lockfile formats, various optimizations, and verifying correctness of a package tree. (@iarna)
  • 47e8fc8eb #17508 Make npm ls take package locks (and shrinkwraps) into account. This means npm ls can now be used to see which dependencies are missing, so long as a package lock has been previously generated with it in. (@iarna)
  • f0075e7ca #17508 Take package.json changes into account when running installs -- if you remove or add a dependency to package.json manually, npm will now pick that up and update your tree and package lock accordingly. (@iarna)
  • 83a5455aa #17205 Add npm udpate as an alias for npm update, for symmetry with install/isntall. (@gdassori)
  • 57225d394 #17120 npm will no longer warn about preferGlobal, and the option is now deprecated. (@zkat)
  • 82df7bb16 #17351 As some of you may already know npm build doesn't do what a lot of people expect: It's mainly an npm plumbing command, and is part of the more familiar npm rebuild command. That said, a lot of users assume that this is the way to run an npm run-script named build, which is an incredibly common script name to use. To clarify things for users, and encourage them to use npm run build instead, npm will now warn if npm build is run without any arguments. (@lennym)

PERFORMANCE

  • 59f86ef90 43be9d222 e906cdd98 #16633 npm now parallelizes tarball extraction across multiple child process workers. This can significantly speed up installations, specially when installing from cache, and will improve with number of processors. (@zkat)
  • e0849878d #17441 Avoid building environment for empty lifecycle scripts. This change alone accounted for as much as a 15% speed boost for npm installations by outright skipping entire steps of the installer when not needed. (@mikesherov)
  • 265c2544c npm/hosted-git-info#24 hosted-git-info@2.5.0: Add caching to fromURL, which gets called many, many times by the installer. This improved installation performance by around 10% on realistic application repositories. (@mikesherov)
  • 901d26cb npm/read-package-json#20 read-package-json@2.0.9: Speed up installs by as much as 20% by reintroducing a previously-removed cache and making it actually be correct this time around. (@mikesherov)
  • 44e37045d Eliminate Bluebird.promisifyAll from our codebase. (@iarna)
  • 3b4681b53 #17508 Stop calling addBundle on locked deps, speeding up the package-lock.json-based fast path. (@iarna)

BUGFIXES

  • #17508 This is a big PR that fixes a variety of issues when installing from package locks. If you were previously having issues with missing dependencies or unwanted removals, this might have fixed it:
    • It introduces a new package-lock.json field, called requires, which tracks which modules a given module requires.
    • It fixes #16839 which was caused by not having this information available, particularly when git dependencies were involved.
    • It fixes #16866, allowing the package.json to trump the package-lock.json.
    • npm ls now loads the shrinkwrap, which opens the door to showing a full tree of dependencies even when nothing is yet installed. (It doesn't do that yet though.) (@iarna)
  • 656544c31 d21ab57c3 #16637 Fix some cases where npm prune was leaving some dependencies unpruned if to-be-pruned dependencies depended on them. (@exogen)
  • 394436b09 #17552 Make refresh-package-json re-verify the package platform. This fixes an issue most notably experienced by Windows users using create-react-app where fsevents would not short-circuit and cause a crash during its otherwise-skipped native build phase. (@zkat)
  • 9e5a94354 #17590 Fix an issue where npm@5 would crash when trying to remove packages installed with npm@<5. (@iarna)
  • c3b586aaf #17141 Don't update the package.json when modifying packages that don't go there. This was previously causing package.json to get a "false": {} field added. (@iarna)
  • d04a23de2 4a5b360d5 d9e53db48 pacote@2.7.38:
  • e2f815f87 #17104 Write an empty str and wait for flush to exit to reduce issues with npm exiting before all output is complete when it's a child process. (@zkat)
  • 835fcec60 #17060 Make git repos with prepare scripts always install with both dev and prod flags. (@intellix)
  • f1dc8a175 #16879 Fix support for always-auth and _auth. They are now both available in both unscoped and registry-scoped configurations. (@jozemlakar)
  • ddd8a1ca2 Serialize package specs to prevent [object Object] showing up in logs during extraction. (@zkat)
  • 99ef3b52c #17505 Stop trying to commit updated npm-shrinkwrap.json and package-lock.json if they're .gitignored. (@zkat)
  • 58be2ec59 Make sure uid and gid are getting correctly set even when they're 0. This should fix some Docker-related issues with bad permissions/broken ownership. (@rgrove) (@zkat)
  • 9d1e3b6fa #17506 Skip writing package.json and locks if on-disk version is identical to the new one. (@zkat)
  • 3fc6477a8 #17592 Fix an issue where npm install -g . on a package with no name field would cause the entire global node_modules directory to be replaced with a symlink to $CWD. lol. (@iarna)
  • 06ba0a14a #17591 Fix spurious removal reporting: if you tried to remove something that didn't actually exist, npm would tell you it removed 1 package even though there was nothing to do. (@iarna)
  • 20ff05f8 #17629 When removing a link, keep dependencies installed inside of it instead of removing them, if the link is outside the scope of the current project. This fixes an issue where removing globally-linked packages would remove all their dependencies in the source directory, as well as some ergonomic issues when using links in other situations. (@iarna)

DOCS

MISC

Not all contributions need to be visible features, docs, or bugfixes! It's super helpful when community members go over our code and help clean it up, too!

v5.0.4 (2017-06-13):

  • 2b1e40efb Limit shallow cloning to hosts which are known to support it. (@zkat)

v5.0.3 (2017-06-05)

Happy Monday, y'all! We've got another npm release for you with the fruits of our ongoing bugsquashing efforts. You can expect at least one more this week, but probably more -- and as we announced last week, we'll be merging fixes more rapidly into the npmc canary so you can get everything as soon as possible!

Hope y'all are enjoying npm5 in the meantime, and don't hesitate to file issues for anything you find! The goal is to get this release rock-solid as soon as we can. 💚

  • 6e12a5cc0 Bump several dependencies to get improvements and bugfixes:
    • cacache: content files (the tarballs) are now read-only.
    • pacote: fix failing clones with bad heads, send extra TLS-related opts to proxy, enable global auth configurations and _auth-based auth.
    • ssri: stop crashing with can't call method find of undefined when running into a weird opts.integrity/opts.algorithms conflict during verification. (@zkat)
  • 89cc8e3e1 #16917 Send ca, cert and key config through to network layer. (@colinrotherham)
  • 6a9b51c67 #16929 Send npm-session header value with registry requests again. (@zarenner)
  • 662a15ab7 Fix npm doctor so it stop complaining about read-only content files in the cache. (@zkat)
  • 191d10a66 #16918 Clarify prepublish deprecation message. (@Hirse)

v5.0.2 (2017-06-02)

Here's another patch release, soon after the other!

This particular release includes a slew of fixes to npm's git support, which was causing some issues for a chunk of people, specially those who were using self-hosted/Enterprise repos. All of those should be back in working condition now.

There's another shiny thing you might wanna know about: npm has a Canary release now! The npm5 experiment we did during our beta proved to be incredibly successful: users were able to have a tight feedback loop between reports and getting the bugfixes they needed, and the CLI team was able to roll out experimental patches and have the community try them out right away. So we want to keep doing that.

From now on, you'll be able to install the 'npm canary' with npm i -g npmc. This release will be a separate binary (npmc. Because canary. Get it?), which will update independently of the main CLI. Most of the time, this will track release-next or something close to it. We might occasionally toss experimental branches in there to see if our more adventurous users run into anything interesting with it. For example, the current canary (npmc@5.0.1-canary.6) includes an experimental multiproc branch that parallelizes tarball extraction across multiple processes.

If you find any issues while running the canary version, please report them and let us know it came from npmc! It would be tremendously helpful, and finding things early is a huge reason to have it there. Happy hacking!

A NOTE ABOUT THE ISSUE TRACKER

Just a heads up: We're preparing to do a massive cleanup of the issue tracker. It's been a long time since it was something we could really keep up with, and we didn't have a process for dealing with it that could actually be sustainable.

We're still sussing the details out, and we'll talk about it more when we're about to do it, but the plan is essentially to close old, abandoned issues and start over. We will also add some automation around issue management so that things that we can't keep up with don't just stay around forever.

Stay tuned!

GIT YOLO

  • 1f26e9567 pacote@2.7.27: Fixes installing committishes that look like semver, even though they're not using the required #semver: syntax. (@zkat)
  • 85ea1e0b9 npm-package-arg@5.1.1: This includes the npa git-parsing patch to make it so non-hosted SCP-style identifiers are correctly handled. Previously, npa would mangle them (even though hosted-git-info is doing the right thing for them). (@zkat)

COOL NEW OUTPUT

The new summary output has been really well received! One downside that reared its head as more people used it, though, is that it doesn't really tell you anything about the toplevel versions it installed. So, if you did npm i -g foo, it would just say "added 1 package". This patch by @rmg keeps things concise while still telling you what you got! So now, you'll see something like this:

$ npm i -g foo bar
+ foo@1.2.3
+ bar@3.2.1
added 234 packages in .005ms
  • 362f9fd5b #16899 For every package that is given as an argument to install, print the name and version that was actually installed. (@rmg)

OTHER BUGFIXES

DOC UPDATES

  • 89e0cb816 #16818 Fixes a spelling error in the docs. Because the CLI team has trouble spelling "package", I guess. (@ankon)
  • c01fbc46e #16895 Remove --save from npm init instructions, since it's now the default. (@jhwohlgemuth)
  • 80c42d218 Guard against cycles when inflating bundles, as symlinks are bundles now. (@iarna)
  • 7fe7f8665 #16674 Write the builtin config for npmc, not just npm. This is hardcoded for npm self-installations and is needed for Canary to work right. (@zkat)

DEP UPDATES

v5.0.1 (2017-05-31):

Hey y'all! Hope you're enjoying the new npm!

As you all know, fresh software that's gone through major overhauls tends to miss a lot of spots the old one used to handle well enough, and npm@5 is no exception. The CLI team will be doing faster release cycles that go directly to the latest tag for a couple of weeks while 5 stabilizes a bit and we're confident the common low-hanging fruit people are running into are all taken care of.

With that said: this is our first patch release! The biggest focus is fixing up a number of git-related issues that folks ran into right out the door. It also fixes other things, like some proxy/auth-related issues, and even has a neat speed boost! (You can expect more speed bumps in the coming releases as pending work starts landing, too!)

Thanks everyone who's been reporting issues and submitting patches!

BUGFIXES

DOCUMENTATION

OTHER CHANGES

v5.0.0 (2017-05-25)

Wowowowowow npm@5!

This release marks months of hard work for the young, scrappy, and hungry CLI team, and includes some changes we've been hoping to do for literally years. npm@5 takes npm a pretty big step forward, significantly improving its performance in almost all common situations, fixing a bunch of old errors due to the architecture, and just generally making it more robust and fault-tolerant. It comes with changes to make life easier for people doing monorepos, for users who want consistency/security guarantees, and brings semver support to git dependencies. See below for all the deets!

Breaking Changes

  • Existing npm caches will no longer be used: you will have to redownload any cached packages. There is no tool or intention to reuse old caches. (#15666)

  • npm install ./packages/subdir will now create a symlink instead of a regular installation. file://path/to/tarball.tgz will not change -- only directories are symlinked. (#15900)

  • npm will now scold you if you capitalize its name. seriously it will fight you.

  • npm will --save by default now. Additionally, package-lock.json will be automatically created unless an npm-shrinkwrap.json exists. (#15666)

  • Git dependencies support semver through user/repo#semver:^1.2.3 (#15308) (#15666) (@sankethkatta)

  • Git dependencies with prepare scripts will have their devDependencies installed, and npm install run in their directory before being packed.

  • npm cache commands have been rewritten and don't really work anything like they did before. (#15666)

  • --cache-min and --cache-max have been deprecated. (#15666)

  • Running npm while offline will no longer insist on retrying network requests. npm will now immediately fall back to cache if possible, or fail. (#15666)

  • package locks no longer exclude optionalDependencies that failed to build. This means package-lock.json and npm-shrinkwrap.json should now be cross-platform. (#15900)

  • If you generated your package lock against registry A, and you switch to registry B, npm will now try to install the packages from registry B, instead of A. If you want to use different registries for different packages, use scope-specific registries (npm config set @myscope:registry=https://myownregist.ry/packages/). Different registries for different unscoped packages are not supported anymore.

  • Shrinkwrap and package-lock no longer warn and exit without saving the lockfile.

  • Local tarballs can now only be installed if they have a file extensions .tar, .tar.gz, or .tgz.

  • A new loglevel, notice, has been added and set as default.

  • One binary to rule them all: ./cli.js has been removed in favor of ./bin/npm-cli.js. In case you were doing something with ./cli.js itself. (#12096) (@watilde)

  • Stub file removed (#16204) (@watilde)

  • The "extremely legacy" _token couchToken has been removed. (#12986)

Feature Summary

Installer changes

  • A new, standardised lockfile feature meant for cross-package-manager compatibility (package-lock.json), and a new format and semantics for shrinkwrap. (#16441)

  • --save is no longer necessary. All installs will be saved by default. You can prevent saving with --no-save. Installing optional and dev deps is unchanged: use -D/--save-dev and -O/--save-optional if you want them saved into those fields instead. Note that since npm@3, npm will automatically update npm-shrinkwrap.json when you save: this will also be true for package-lock.json. (#15666)

  • Installing a package directory now ends up creating a symlink and does the Right Thing™ as far as saving to and installing from the package lock goes. If you have a monorepo, this might make things much easier to work with, and probably a lot faster too. 😁 (#15900)

  • Project-level (toplevel) preinstall scripts now run before anything else, and can modify node_modules before the CLI reads it.

  • Two new scripts have been added, prepack and postpack, which will run on both npm pack and npm publish, but NOT on npm install (without arguments). Combined with the fact that prepublishOnly is run before the tarball is generated, this should round out the general story as far as putzing around with your code before publication.

  • Git dependencies with prepare scripts will now have their devDependencies installed, and their prepare script executed as if under npm pack.

  • Git dependencies now support semver-based matching: npm install git://github.com/npm/npm#semver:^5 (#15308, #15666)

  • node-gyp now supports node-gyp.cmd on Windows (#14568)

  • npm no longer blasts your screen with the whole installed tree. Instead, you'll see a summary report of the install that is much kinder on your shell real-estate. Specially for large projects. (#15914):

$ npm install
npm added 125, removed 32, updated 148 and moved 5 packages in 5.032s.
$

  • --parseable and --json now work more consistently across various commands, particularly install and ls.

  • Indentation is now detected and preserved for package.json, package-lock.json, and npm-shrinkwrap.json. If the package lock is missing, it will default to package.json's current indentation.

Publishing

Cache Rewrite!

We've been talking about rewriting the cache for a loooong time. So here it is. Lots of exciting stuff ahead. The rewrite will also enable some exciting future features, but we'll talk about those when they're actually in the works. #15666 is the main PR for all these changes. Additional PRs/commits are linked inline.

  • Package metadata, package download, and caching infrastructure replaced.

  • It's a bit faster. Hopefully it will be noticeable. 🤔

  • With the shrinkwrap and package-lock changes, tarballs will be looked up in the cache by content address (and verified with it).

  • Corrupted cache entries will automatically be removed and re-fetched on integrity check failure.

  • npm CLI now supports tarball hashes with any hash function supported by Node.js. That is, it will use sha512 for tarballs from registries that send a sha512 checksum as the tarball hash. Publishing with sha512 is added by npm/npm-registry-client#157 and may be backfilled by the registry for older entries.

  • Remote tarball requests are now cached. This means that even if you're missing the integrity field in your shrinkwrap or package-lock, npm will be able to install from the cache.

  • Downloads for large packages are streamed in and out of disk. npm is now able to install packages of """any""" size without running out of memory. Support for publishing them is pending (due to registry limitations).

  • Automatic fallback-to-offline mode. npm will seamlessly use your cache if you are offline, or if you lose access to a particular registry (for example, if you can no longer access a private npm repo, or if your git host is unavailable).

  • A new --prefer-offline option will make npm skip any conditional requests (304 checks) for stale cache data, and only hit the network if something is missing from the cache.

  • A new --prefer-online option that will force npm to revalidate cached data (with 304 checks), ignoring any staleness checks, and refreshing the cache with revalidated, fresh data.

  • A new --offline option will force npm to use the cache or exit. It will error with an ENOTCACHED code if anything it tries to install isn't already in the cache.

  • A new npm cache verify command that will garbage collect your cache, reducing disk usage for things you don't need (-handwave-), and will do full integrity verification on both the index and the content. This is also hooked into npm doctor as part of its larger suite of checking tools.

  • The new cache is very fault tolerant and supports concurrent access.

    • Multiple npm processes will not corrupt a shared cache.
    • Corrupted data will not be installed. Data is checked on both insertion and extraction, and treated as if it were missing if found to be corrupted. I will literally bake you a cookie if you manage to corrupt the cache in such a way that you end up with the wrong data in your installation (installer bugs notwithstanding).
    • npm cache clear is no longer useful for anything except clearing up disk space.

  • Package metadata is cached separately per registry and package type: you can't have package name conflicts between locally-installed packages, private repo packages, and public repo packages. Identical tarball data will still be shared/deduplicated as long as their hashes match.

  • HTTP cache-related headers and features are "fully" (lol) supported for both metadata and tarball requests -- if you have your own registry, you can define your own cache settings the CLI will obey!

  • prepublishOnly now runs before the tarball to publish is created, after prepare has run.
