/**
|
|
* Select Firebase Realtime Database Reference to listen to.
|
|
*
|
|
* This method behaves very similarly to the method of the same name in the
|
|
* client and Admin Firebase SDKs. Any change to the Database that affects the
|
|
* data at or below the provided `path` will fire an event in Cloud Functions.
|
|
*
|
|
* There are three important differences between listening to a Realtime
|
|
* Database event in Cloud Functions and using the Realtime Database in the
|
|
* client and Admin SDKs:
|
|
* 1. Cloud Functions allows wildcards in the `path` name. Any `path` component
|
|
* in curly brackets (`{}`) is a wildcard that matches all strings. The value
|
|
* that matched a certain invocation of a Cloud Function is returned as part
|
|
* of the `context.params` object. For example, `ref("messages/{messageId}")`
|
|
* matches changes at `/messages/message1` or `/messages/message2`, resulting
|
|
* in `context.params.messageId` being set to `"message1"` or `"message2"`,
|
|
* respectively.
|
|
* 2. Cloud Functions do not fire an event for data that already existed before
|
|
* the Cloud Function was deployed.
|
|
* 3. Cloud Function events have access to more information, including information
|
|
* about the user who triggered the Cloud Function.
|
|
* @param ref Path of the database to listen to.
