# call-me-maybe [](https://travis-ci.org/limulus/call-me-maybe)

Let your JS API users either give you a callback or receive a promise.
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var maybe = require("call-me-maybe")
|
|
|
|
module.exports = function asyncFunc (cb) {
|
|
return maybe(cb, new Promise(function(resolve, reject) {
|
|
// ...
|
|
}))
|
|
}
|
|
```
|
|
|
|
## API
|
|
|
|
### maybe(cb, promise)
|
|
|
|
If the callback `cb` is truthy, returns `undefined` and will call `cb` when `promise` is settled. The parameters passed to `cb` are standard error-first:
|
|
|
|
- If `promise` is fulfilled, then it is called with the result of the promise: `cb(null, result)`
|
|
- If `promise` is rejected, then it is called with the rejection error: `cb(err)`
|
|
|
|
If `cb` is falsey, then `promise` is retuned.
