Getting started as a developer

There are several ways to get started. Like using the Docker setup or use the development server, which is explained in detail below.

The code is mainly written in PHP using the Symfony framework with Twig templating and a bit of JavaScript & CSS and of course HTML.

Docker as a dev server

To save yourself much time setting up a development server, you can use our Docker setup instead of a manual configuration:

1. Make sure you are currently in the root of your Mbin directory.
2. Run the auto setup script with ./docker/setup.sh dev localhost to configure .env, compose.override.yaml, and storage/.

note

The Docker setup uses ports 80 and 443 by default. If you'd prefer to use a different port for development on your device, then in .env you'll need to update KBIN_DOMAIN and KBIN_STORAGE_URL to include the port number (e.g., localhost:8443). Additionally, add the following to compose.dev.yaml under the php service:

ports: !override
  - 8443:443

3. Run docker compose up to build and start the Docker containers. Please note that the first time you start the containers, they will need an extra minute or so to install dependencies before becoming available.
4. From here, you should be able to access your server at https://localhost/. Any edits to the source files will automatically rebuild your server.
5. Optionally, follow the Mbin first setup instructions.
6. If you'd like to enable federation capabilities, then in compose.dev.yaml, change the two lines from replicas: 0 to replicas: 1 (under the messenger and rabbitmq services). Make sure you've ran the containers at least once before doing this, to give the php service a chance to install dependencies without overlap.

note

If you'd prefer to manually configure your Docker environment (instead of using the setup script) then follow the manual environment setup steps in the Docker install guide, but while you're creating compose.override.yaml, use the following:

include:
  - compose.dev.yaml

tip

Once you are done with your development server and would like to shutdown the Docker containers, hit Ctrl+C in your terminal.

If you'd prefer a development setup without using Docker, then continue on to the next sections.

Initial setup

Requirements:

• PHP v8.3 or higher
• NodeJS v20 or higher
• Valkey / KeyDB / Redis (pick one)
• PostgreSQL
• Optionally: Mercure
• Optionally: Symfony CLI

First install some generic packages you will need:

sudo apt update
sudo apt install lsb-release ca-certificates curl wget unzip gnupg apt-transport-https software-properties-common git valkey-server

Clone the code

With an account on GitHub you will be able to fork this repository.

Once you forked the GitHub repository you can clone it locally (our advice is to use SSH to clone repositories from GitHub):

git clone git-repository-url

For example:

git clone git@github.com:MbinOrg/mbin.git

tip

You do not need to fork the GitHub repository if you are member of our Mbin Organisation on GitHub. Just create a new branch right away.

Prepare PHP

1. Install PHP + additional PHP extensions:

sudo apt install php8.4 php8.4-common php8.4-fpm php8.4-cli php8.4-amqp php8.4-bcmath php8.4-pgsql php8.4-gd php8.4-curl php8.4-xml php8.4-redis php8.4-mbstring php8.4-zip php8.4-bz2 php8.4-intl php8.4-bcmath -y

2. Fine-tune PHP settings:

• Increase execution time in PHP config file: /etc/php/8.4/fpm/php.ini:

max_execution_time = 120

• Optional: Increase/set max_nesting_level in /etc/php/8.4/fpm/conf.d/20-xdebug.ini (in case you have the xdebug extension installed):

xdebug.max_nesting_level=512

3. Restart the PHP-FPM service:

sudo systemctl restart php8.4-fpm.service

Prepare PostgreSQL DB

1. Install PostgreSQL:

sudo apt-get install postgresql postgresql-contrib

2. Connect to PostgreSQL using the postgres user:

sudo -u postgres psql

3. Create a new mbin database user with database:

sudo -u postgres createuser --createdb --createrole --pwprompt mbin

4. If you are using 127.0.0.1 to connect to the PostgreSQL server, edit the following file: /etc/postgresql/<VERSION>/main/pg_hba.conf and add:

local   mbin            mbin                                    md5

5. Finally, restart the PostgreSQL server:

sudo systemctl restart postgresql

Prepare dotenv file

1. Change to the mbin git repository directory (if you weren't there already).
2. Copy the dot env file: cp .env.example .env. And let's configure the .env file to your needs. Pay attention to the following changes:

# Set domain to 127.0.0.1:8000
SERVER_NAME=127.0.0.1:8000
KBIN_DOMAIN=127.0.0.1:8000
KBIN_STORAGE_URL=http://127.0.0.1:8000/media

# Valkey/Redis (without password)
REDIS_DNS=redis://127.0.0.1:6379

# Set App configs
APP_ENV=dev
APP_SECRET=427f5e2940e5b2472c1b44b2d06e0525

# Configure PostgreSQL
POSTGRES_DB=mbin
POSTGRES_USER=mbin
# Change your PostgreSQL password for Mbin user
POSTGRES_PASSWORD=<password>

# Set messenger to Doctrine (= PostgresQL DB)
MESSENGER_TRANSPORT_DSN=doctrine://default

Install Symfony CLI tool

1. Install Symfony CLI: wget https://get.symfony.com/cli/installer -O - | bash
2. Check the requirements: symfony check:requirements

Fill Database

1. Assuming you are still in the mbin directory.
2. Create the database: php bin/console doctrine:database:create
3. Create tables and database structure: php bin/console doctrine:migrations:migrate

Fixtures

tip

This fixtures section is optional. Feel free to skip this section.

You might want to load random data to database instead of manually adding magazines, users, posts, comments etc. To do so, execute:

php bin/console doctrine:fixtures:load --append --no-debug

---

If you have messenger jobs configured, be sure to stop them:

• Docker: docker compose stop messenger
• Bare Metal: supervisorctl stop messenger:*

If you are using the Docker setup and want to load the fixture, execute:

docker compose exec php bin/console doctrine:fixtures:load --append --no-debug

Please note, that the command may take some time and data will not be visible during the process, but only after the finish.

• Omit --append flag to override data currently stored in the database
• Customize inserted data by editing files inside src/DataFixtures directory

Starting the development server

Prepare the server:

1. Build frontend assets: npm install && npm run dev
2. Install dependencies: composer install
3. Dump .env into .env.local.php via: composer dump-env dev
4. Optionally: Increase verbosity log level in: config/packages/monolog.yaml in the when@dev section: level: debug (instead of level: info),
5. Important: clear Symfony cache: APP_ENV=dev APP_DEBUG=1 php bin/console cache:clear -n
6. Optionally: clear the Composer cache: composer clear-cache

Start the development server:

6. Start Mbin: symfony server:start
7. Go to: http://127.0.0.1:8000

tip

Once you are done with your development server and would like to shut it down, hit Ctrl+C in your terminal.

You might want to also follow the Mbin first setup. This explains how to create a user.

This will give you a minimal working frontend with PostgreSQL setup. Keep in mind: this will not start federating.

Optionally: If you want to start federating, you will also need to messenger jobs + RabbitMQ and host your server behind a reverse proxy with valid SSL certificate. Generally speaking, it's not required to setup federation for development purposes.

Testing

When fixing a bug or implementing a new feature or improvement, we expect that test code will also be included with every delivery of production code. There are three levels of tests that we distinguish between:

• Unit Tests: test a specific unit (SUT), mock external functions/classes/database calls, etc. Unit-tests are fast, isolated and repeatable
• Integration Tests: test larger part of the code, combining multiple units together (classes, services or alike).
• Application Tests: test high-level functionality, APIs or web calls.

For more info read: Symfony Testing guide.

Prepare testing

1. First increase execution time in your PHP config file: /etc/php/8.4/fpm/php.ini:

max_execution_time = 120

2. Optional: Increase/set max_nesting_level in /etc/php/8.4/fpm/conf.d/20-xdebug.ini (in case you have the xdebug extension installed):

xdebug.max_nesting_level=512

3. Restart the PHP-FPM service: sudo systemctl restart php8.4-fpm.service
4. Copy the dot env file (if you haven't already): cp .env.example .env
5. Install composer packages: composer install --no-scripts

Running unit tests

Running the unit tests can be done by executing:

SYMFONY_DEPRECATIONS_HELPER=disabled ./bin/phpunit tests/Unit

Running integration tests

Our integration tests depend on a database and a caching server (Valkey / KeyDB / Redis). The database and cache are cleared / dumped every test run.

To start the services in the background:

docker compose -f docker/tests/compose.yaml up -d

Then run the integration test(s):

SYMFONY_DEPRECATIONS_HELPER=disabled ./bin/phpunit tests/Functional
