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

Usage Example

var FirebaseServer = require('firebase-server');

new FirebaseServer(5000, 'localhost.firebaseio.test', {
	states: {
		CA: 'California',
		AL: 'Alabama',
		KY: 'Kentucky'
	}
});

After running this server, you can create a Firebase client instance that connects to it:

var client = new Firebase('ws://localhost.firebaseio.test:5000');
client.on('value', function(snap) {
	console.log('Got value: ', snap.val());
});

Don't forget to point the host localhost.firebaseio.test to your local IP address (in /etc/hosts or similar).

For more information, read the blog post in the offical Firebase blog.

Command Line Interface

This package installs a CLI script called firebase-server. The following command will start a firebase server on port 5555:

node_modules/.bin/firebase-server -p 5555

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.

node_modules/.bin/firebase-server -d '{"foo": "bar"}'

node_modules/.bin/firebase-server -f ./path/to/data.json

To load Firebase Security rules upon startup you can use the -r,--rules option.

node_modules/.bin/firebase-server -r ./path/to/rules.json

For more information, run:

node_modules/.bin/firebase-server -h

FirebaseServer methods

FirebaseServer instances have the following API:

close(callback) - Stops the server (closes the server socket) and then calls the callback
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().
setRules(rules) - Sets the security rules for the server. Uses the targaryen library for rule validation.
setAuthSecret(secret) - Sets the shared secret used for validating Custom Authentication Tokens.
setTime(timestamp) - Sets the server time. The server time is returned by ServerValue.TIMESTAMP and is also used for checking the validity of Custom Authentication Tokens.

Debug logging

This project uses the excellent debug module for logging. It is configured by setting an environment variable:

$ 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
