Symfony Event Manager Demo

In preparation for this project, I implemented the following steps:

1. Docker containers created with PHP, Nginx and MySql
2. Symfony application created
   • Basic framework created with composer create-project symfony/skeleton /var/www/html
   • composer require webapp executed to install extra packages to get everything you need to build a web application
3. Symfony CLI installed (Dockerfile extended)
   • Added wget to installed dependencies
   • Added RUN wget https://get.symfony.com/cli/installer -O - | bash && \ mv /root/.symfony*/bin/symfony /usr/local/bin/symfony
   • Removed containers docker compose down
   • Created containers docker compose build
   • Started containers docker compose up -d

These steps served as preparation to get the Symfony application running. There are different ways to do this including:

1. Installing & Setting up the Symfony Framework
2. Using Docker with Symfony

These steps no longer need to be carried out for this application. They serve for understanding.

Helpful Symfony Commands

To save time, you can install Symfony Maker or Symfony CLI to use helpful commands. For this project I am using the Symfony CLI, so every command starts with symfony console. If you use Symfony Maker, every command starts with php bin/console

Generate a new controller class:

symfony console make:controller BrandNewController

created: src/Controller/BrandNewController.php
created: templates/brandnew/index.html.twig

Generate an entire CRUD from a Doctrine entity (assuming the entity already exists):

symfony console make:crud Product

created: src/Controller/ProductController.php
created: src/Form/ProductType.php
created: templates/product/_delete_form.html.twig
created: templates/product/_form.html.twig
created: templates/product/edit.html.twig
created: templates/product/index.html.twig
created: templates/product/new.html.twig
created: templates/product/show.html.twig

Installation

In order to make the local URL accessible in the browser, the "hosts file" must be adapted. On Mac and Linux systems they can be found under "/etc/hosts". Add the following entry:

# Symfony Event Manager Demo
127.0.0.1       sfeventmanagerdemo.local

1. Clone the repository
2. Build the Docker Container

   make build
   

3. Run the Docker Container

   make startup
   

4. Create .env file from env.sample from the root directory level of the web project

   cp src/.env.example src/.env
   

5. Open a terminal and go to the root directory level of the web project and run

   docker exec -it php-container bash
   

6. Create value for APP_SECRET in .env file and replace it with the new value

   openssl rand -hex 32
   

7. Execute

   composer install
   

8. Open a new browser tab and enter the domain http://sfeventmanagerdemo.local:8080/
