# Project Deprecated!
> This project has reached its end-of-life, and will no longer be maintained. For information about the official alternative from the Firebase team, have a look at the [Firebase Local Emulators Migration Guide](docs/firebase-emulators.md).
Moving forward, new features will not be added, and only security-related bugfixes will be released.
firebase-server
===============
Firebase Web Socket Protocol Server. Useful for emulating the Firebase server in tests.

Installation
------------
You can install firebase-server through npm:
`npm install --save-dev firebase-server`
or yarn:
`yarn add -D firebase-server`
Usage examples
-------------
```js
const FirebaseServer = require('firebase-server');
new FirebaseServer(5000, 'localhost', {
states: {
CA: 'California',
AL: 'Alabama',
KY: 'Kentucky'
}
});
```
After running this server, you can create a Firebase client instance that connects to it:
```js
import * as firebase from 'firebase/app';
import 'firebase/database';
const app = firebase.initializeApp({
databaseURL: `ws://localhost:5000`,
});
app.database().ref().on('value', (snap) => {
console.log('Got value: ', snap.val());
});
```
### Setup with global test hooks
In the case of Mocha, you'd do something like the example below.
```js
// => e.g. global-test-hooks.js
const FirebaseServer = require("firebase-server");
let firebaseServer;
before(() => {
firebaseServer = new FirebaseServer(5000, "localhost");
});
after(async () => {
await firebaseServer.close();
});
```
```
// => require the file with the --file flag
mocha --file /path/to/global-test-hooks.js
```
### Command Line Interface
This package installs a CLI script called `firebase-server`.
It can be installed locally or globally. If installed locally, use the
following path to start the server: `./node_modules/.bin/firebase-server`
The following command will start a firebase server on port 5555:
firebase-server -p 5555
... and with a specified bind IP address:
firebase-server -p 5555 -a 0.0.0.0
To bootstrap the server with some data you can use the `-d,--data` or the `-f,--file` option.
_Note: The file option will override the data option._
firebase-server -d '{"foo": "bar"}'
firebase-server -f ./path/to/data.json
To load [Firebase Security rules](https://firebase.google.com/docs/database/security/) upon startup you can use the `-r,--rules` option.
firebase-server -r ./path/to/rules.json
You can also specify a shared client auth token secret with the `-s` argument:
firebase-server -s some-shared-secret
To enable REST API, run:
firebase-server -e
_Note: currently REST API does not implement authentication or
authorization._
To daemonize the server process, use:
firebase-server -b
To write the PID to a file, use:
firebase-server --pid /var/run/firebase-server.pid
_Note: PID file can be written with or without daemonization, and is NOT
written by default when daemonizing.
For more information, run:
firebase-server -h
### FirebaseServer methods
The constructor signature is `FirebaseServer(portOrOptions, name, data)` where
`portOrOptions` is either a port number or a
[`WebSocket.Server`](https://github.com/websockets/ws/blob/master/doc/ws.md#new-websocketserveroptions-callback)
options object with either `port` or `server` set. `name` is optional and is
just used to report the server name to clients. `data` is the initial contents
of the database.
If you want the server to pick a free port for you, simply use the value `0` for the port. You can then get the
assigned port number by calling the `getPort()` method on the returned server object.
FirebaseServer instances have the following API:
* `close(): Promise` - Stops the server (closes the server socket)
* `getValue()` - Returns a promise that will be resolved with the current data on the server
* `exportData()` - Returns a promise that will be resolved with the current data on the server, including priority values.
This is similar to [DataSnapshot.exportVal()](https://www.firebase.com/docs/web/api/datasnapshot/exportval.html).
* `address()` - Returns the address the server is listening on
* `port(): number` - Returns the port number the server is listening on
* `setRules(rules)` - Sets the security rules for the server. Uses the [targaryen](https://github.com/goldibex/targaryen)
library for rule validation.
* `setAuthSecret(secret)` - Sets the shared secret used for validating [Custom Authentication Tokens](https://www.firebase.com/docs/web/guide/login/custom.html).
* `setTime(timestamp)` - Sets the server time. The server time is returned by [ServerValue.TIMESTAMP](https://www.firebase.com/docs/web/api/servervalue/timestamp.html)
and is also used for checking the validity of Custom Authentication Tokens.
### Debug logging
This project uses the excellent [`debug`](https://www.npmjs.com/package/debug) module for logging.
It is configured by setting an environment variable:
```sh
$ DEBUG=* mocha # log everything
$ DEBUG=firebase-server* mocha # log everything from firebase-server
$ DEBUG=firebase-server:token-generator mocha # log output from specific submodule
```
Advanced options are available from the [`debug docs`](https://www.npmjs.com/package/debug)
