Lighthouse - Laravel Websockets integration example

This project contains the implementation of Lighthouse subscription with pusher/laravel-websockets. If you're looking for the implementation of echo driver, then check the implementation in this repository.

Version

This repository contains Laravel 8.x and Lighthouse 5.2.x

Dependencies, requirements and build tools

This project comes with docker & docker-compose. But to minimize the boot up time when you try docker-compose up -d --build the local files are mounted to application & worker containers and NOT COPIED TO CONTAINERS. Thus, it's recommended to use PHP & composer locally. Resolve your project dependency before you run your application using composer install. But you need node environment to build the JS dependency if you're not using pusher but the echo driver for subscription. Follow the attached article.

How to use?

  • Clone the repository.
  • cp docker-compose.yml.example docker-compose.yml.
  • Make the required changes to your docker-compose.yml.
  • cp .env.example .env.
  • Make the required changes to your .env.
  • Run php artisan key:generate to generate application key.
  • touch database/database.sqlite to create sqlite database.
  • php artisan migrate to migrate the database.
  • yarn install to install the dependencies.
  • yarn run watch to build the JS files.
  • docker-compose up -d --build to build your containers.
  • Loading http://127.0.0.1:{PHP_PORT} in your browser will return a json response.
  • If you don't have composer locally, then exec-ing to php container after containers are up and install the dependencies will work. Just restart the containers.
  • If you're changing the environment variables, make sure to change them other places and run commands if required.

Working with pusher/laravel-websockets

  • Open served application in your browser. It's on port 8000. Change the port if you changed in the docker-compose.yml's php port.
  • Open playground url in your browser. It's on port 8000. Change the port if you changed the docker-compose.yml's php port.
  • Check the browser's console log if everything is okay or not.
  • Run the following mutation from the playground.
mutation createUser{
  createUser (name: "A")  {
    id
    name
    email
    created_at
    updated_at
    has_arg
    pushed_by_subs_resolver
  }
}
  • You'll get to see the update in your application homepage.
  • Otherwise, click the button on the homepage, you'll see the value gets updated.

Working with echo driver

  • Comment the pusher related variables and imports in resources/js/apollo.js.
  • Uncomment and change the url that points to the other project that has echo driver implemented in resources/js/apollo.js.
  • Copy a JWT token from the other project's login mutation.
  • Open inspect element.
  • Add the copied jwt token in your page's localStorage with the key token.
  • Build the project with yarn run watch.
  • Reload the page.
  • Click the button.

Wait for a few seconds as the other project uses queue to push the data to echo server (by default). And you should be able to see the data changing.
