Laravel 9 Websockets: Everything You Need to Know

The world of web development is constantly evolving, and Laravel is not left behind in this evolution. Laravel 9 is the latest version of the popular PHP framework that comes with a host of new features. One of the most notable features of Laravel 9 is websockets. In this article, we will explore everything you need to know about websockets in Laravel 9.

What are Websockets?

Websockets are a communication protocol that allows for real-time communication between a client and a server. Unlike HTTP, which is a request-response protocol, websockets allow for two-way communication between a client and a server. This means that data can be sent and received in real-time without the need for polling or constant requests.

Why Use Websockets?

Websockets are useful in many scenarios where real-time communication is required. Some of the common use cases for websockets include:

• Real-time chat applications
• Real-time collaboration tools
• Real-time gaming applications
• Real-time data visualization

Laravel and Websockets

Laravel has had support for websockets for a while now, but Laravel 9 takes it to the next level. Laravel 9 introduces a new package called Laravel Echo Server, which makes it easier to work with websockets in Laravel applications.

Installing Laravel Echo Server

To install Laravel Echo Server, you need to have Node.js and npm installed on your system. Once you have Node.js and npm installed, you can install Laravel Echo Server using the following command:

npm install -g laravel-echo-server

Configuring Laravel Echo Server

After installing Laravel Echo Server, you need to configure it for your Laravel application. You can do this by creating a new configuration file called laravel-echo-server.json in the root of your Laravel application. Here is an example configuration file:

1. Run the following command to generate configuration file

   laravel-echo-server init

2. Edit the configuration file. The minimum required configuration options are:

   • “authHost”: “http://localhost:8000”,
   • “authEndpoint”: “/broadcasting/auth”,
   • “database”: “redis”,
   • “devMode”: true,
   • “host”: null,
   • “port”: “6001”,
   • “protocol”: “http”,
   • “socketio”: {},
   • “sslCertPath”: “”,
   • “sslKeyPath”: “”,
   • “sslCertChainPath”: “”,
   • “sslPassphrase”: “”,
   • “subscribers”: {
   •     “http”: true,
   •     “redis”: true
   • }

3. Start Laravel Echo Server by running the following command:

   laravel-echo-server start

Using Websockets in Laravel

Once you have Laravel Echo Server configured and running, you can start using websockets in your Laravel application. Here is an example of how to use websockets in Laravel:

1. First, you need to import Laravel Echo in your JavaScript code:

   import Echo from ‘laravel-echo’;

2. Next, you need to create a new instance of Echo and configure it:

   const echo = new Echo({broadcaster: 'socket.io',host: window.location.hostname + ':6001'});

3. Finally, you can use the broadcast method to send data over websockets:

   echo.channel('test-channel').listen('TestEvent', (data) => {console.log(data);});

Conclusion

Websockets are a powerful tool for building real-time applications, and Laravel 9 makes it easier than ever to work with websockets in PHP applications. Laravel Echo Server provides a simple and easy-to-use interface for working with websockets in Laravel, and with a little bit of configuration, you can be up and running with websockets in no time.
