About

This projects aims to show server-side rendering dynamic web pages with usage of Symfony UX, Symfony framework itself and broadcast protocol mercure. This web application allows for sharing cat images with other users live. Just add images of cats and explore images added by others. Have fun experimenting!

Installation

NOTICE: This application was created with testing and experimenting purpose in mind so is not ready for production. This installation guide was created only for development environment.

Prerequisites

You must have:

• php version 8.1 or later installed on your system
• node.js installed on your system
• npm or yarn node.js package manager
• docker compose
• composer the php package manager

Quick start

Being in root directory of the app in a terminal run ./setup.sh. Make sure that the file is executable. Or you can adjust commands to your needs and run them by yourself. The script consist of following commands:

• docker compose up -d - run container with dunglas/mercure image for broadcast purposes
• composer install --no-interaction - install all required composer dependencies
• npm install --force - install all required node.js dependencies
• npm run build - build webpack files
• ./bin/console d:d:c - create local sqlite database
• ./bin/console d:m:m --no-interaction - run migrations
• ./bin/console d:f:l --no-interaction - run fixtures
• cd public && php -S localhost:8080 - run local php server

NOTICE: If 8080 port is already allocated on your system, and you want to use another port you must change mercure service configuration, because of CORS policy. Just exchange cors_origins http://localhost:8080 with your server URL (line 13 in docker-compose.yml).

NOTICE: If you want to change port binding for mercure service then make sure to change also MERCURE_URL and MERCURE_PUBLIC_URL environment variables in .env file. Also if you want to run application in a container.

Quick tour

When running fixtures two users are created to make your life easier:

• cat_lover@cat.com with password mySuperStrongPassword
• cats_killingit@cat.com with password mySuperStrongPassword

You can use them to sign in into two separate accounts in two separate windows in a browser to watch broadcast in action. Or you can just create a new account by clicking sign up. When signed in you can have a little fun watching cats on the website. The cats pictures were downloaded when running App\DataFixtures\KittieFixture.php with usage of The Cat API into var/files directory. Those files are not publicly available.

Now is the time that you can test broadcast in action. Click 'Share cat' in right upper corner of the application. Upload some image of a cat, give it a name and also specify its breed. You should immediately see new cat prepended in cat gallery in both windows of your browser. Also, you should receive notifications that a new cat was just added. Otherwise, make sure your configuration is correct.
