Welcome to the world of firebase-server, a valuable tool for emulating Firebase server environments. Though the project has reached its end-of-life, it’s still a powerful resource for developers needing to conduct effective testing. This guide will walk you through the installation, usage examples, and additional tips to ensure a smooth experience.

Installation

To start using firebase-server, you need to install it via npm or yarn. Here’s how:

• Using npm: npm install –save-dev firebase-server
• Using yarn: yarn add -D firebase-server

Usage Examples

Now that you’ve installed the server, let’s see how to set it up and use it in your projects.

Setting Up the Server

Here’s a simple analogy to understand setting up the firebase-server better. Think of the server as a chef preparing meals in a kitchen:

• The kitchen is your localhost where the server works.
• The chef (the FirebaseServer instance) waits for orders (incoming connections).
• When an order is received, the chef prepares the dish (processes the data).

Below is the code to set up the server:

const FirebaseServer = require('firebase-server');
new FirebaseServer(5000, 'localhost', {
    states: {
        CA: 'California',
        AL: 'Alabama',
        KY: 'Kentucky'
    }
});

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

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());
});

Advanced Configuration with Mocha

If you are using Mocha for testing, you can set up global test hooks like so:

const FirebaseServer = require('firebase-server');
let firebaseServer;

before(() => {
    firebaseServer = new FirebaseServer(5000, 'localhost');
});
after(async () => {
    await firebaseServer.close();
});

Command Line Interface

You can also control the firebase-server from the command line.

firebase-server -p 5555

This command starts the server on port 5555. You can also specify a different IP address or bootstrap it with data using flags. Here’s an example:

firebase-server -p 5555 -a 0.0.0.0 -d foo:bar

Troubleshooting

If you encounter issues while using firebase-server, here are some troubleshooting steps you can try:

• Ensure you check for port conflicts; make sure the port you intend to use (e.g., 5000) isn’t occupied by another service.
• Try running the server with elevated privileges if you face permission issues.
• If you are unsure about the installation, remove the existing server and reinstall it.
