# Project Guidelines for Junie

## Project Overview

Chill is a comprehensive web application built as a set of Symfony bundles. It is a case management system, for social work. The project consists of multiple specialized bundles that provide different functionalities:

- **ChillMainBundle**: Core bundles that provide the foundation of the application
- **ChillPersonBundle**: Core bundles that provide the foundation of the bundles associated to person (which is the case for all other bundles)
- **ChillCalendarBundle**: Calendar and scheduling functionality
- **ChillDocStoreBundle** and **ChillDocGeneratorBundle**: Document management and generation
- **ChillActivityBundle**, **ChillEventBundle**, **ChillTaskBundle**: Activity and task tracking
- **ChillBudgetBundle**: Financial management
- **ChillThirdPartyBundle**: Integration with external systems
- **ChillCustomFieldsBundle**: Extensibility through custom fields
- **ChillReportBundle**: Save arbitrary reports about persons
- **ChillTicketBundle**: Record and track issues about persons

- And several other specialized bundles

## Technology Stack

- **Backend**: PHP 8.3+, Symfony 5.4
- **Frontend**: JavaScript/TypeScript, Vue.js 3, Bootstrap 5
- **Build Tools**: Webpack Encore, Yarn
- **Database**: PostgreSQL with materialized views. We do not support other databases.
- **Other Services**: Redis, AMQP (RabbitMQ), SMTP

## Project Structure

Note: This is a project that's existed for a long time, and throughout the years we've used multiple structures inside each bundle. When having the choice, the developers should choose the new structure.

The project follows a standard Symfony bundle structure:
- `/src/Bundle/`: Contains all the Chill bundles. The code is either at the root of the bundle directory, or within a `src/` directory (preferred). See psr4 mapping at the root's `composer.json`.
- each bundle comes with its own tests, either in the `Tests` directory (when the code is directly within the bundle directory (for instance `src/Bundle/ChillMainBundle/Tests`, `src/Bundle/ChillPersonBundle/Tests`)), or inside the `tests` directory, alongside the `src/` sub-directory (example: `src/Bundle/ChillWopiBundle/tests`) (this is the preferred way).
- `/docs/`: Contains project documentation

Each bundle typically has the following structure:

- `Controller/`: Contains controllers
- `Entity/`: Contains Doctrine entities
- `Repository/`: Contains Doctrine repositories
- `Resources/`: Contains views, translations, and public assets
- `DependencyInjection/`: Contains service configuration
- `Export/`: Contains services related to exports
- `Security/`: Contains services related to security. Most of the time, those are new voters, and so on.

### A special word about TicketBundle

The ticket bundle is developed using a kind of "Command" pattern. The controller fills a "Command," and a "CommandHandler" handles this command. They are saved in the `src/Bundle/ChillTicketBundle/src/Action` directory.

## Development Guidelines

### Building and Configuration Instructions

All the commands should be run through the `symfony` command, which will configure the required variables.

For assets, we must ensure that we use node at version `^20.0.0`. This is done using `nvm use 20`.

#### Initial Setup

1. **Clone the Repository**:
   ```bash
   git clone <repository-url>
   cd chill-bundles
   ```

2. **Install PHP Dependencies**:
   ```bash
   composer install
   ```

3. **Install JavaScript Dependencies**:
   ```bash
   nvm use 20
   yarn install
   ```

4. **Configure Environment Variables**:

   - Create a `.env.local` file with minimal configuration
   ```bash
   echo "APP_ENV=dev" >> .env.local
   ```

5. Start the associated services (database, and so on):
   ```bash
   docker compose up -d
   ```

6. **Set Up the Database**:
   ```bash
   # Create the database
   symfony console doctrine:database:create

   # Run migrations
   symfony console doctrine:migrations:migrate

   # Load fixtures (optional)
   symfony console doctrine:fixtures:load
   ```

7. **Build Assets**:
   ```bash
   nvm use 20
   yarn run encore dev
   ```

8. **Start the Development Server**:
   ```bash
   symfony server:start -d
   ```

#### Docker Setup

The project includes a Docker configuration for easier development:

1. **Start Docker Services**:
   ```bash
   docker-compose up -d
   ```

2. **Access the Application**:
   - The application will be available at `http://localhost:8000`
   - PostgreSQL will be available at `localhost:5432`
   - Redis will be available at `localhost:6379`

#### Building Assets

Before submitting any changes, you should build the project to ensure that all assets are properly compiled:

```bash
# For production
yarn run encore production

# For development with hot-reloading
yarn run encore dev --watch

# for development
yarn run encore dev
```

#### Configuration Files

Key configuration files:

- `config/packages/*.yaml`: Symfony bundle configurations
- `webpack.config.js`: Webpack Encore configuration
- `composer.json`: PHP dependencies and scripts
- `package.json`: JavaScript dependencies and scripts
- `.env`: Default environment variables. Must usually not be updated: use `.env.local` instead.

### Database migrations

Each time a doctrine entity is created, we generate migration to adapt the database.

The migration is created using the command `symfony console doctrine:migrations:diff --no-interaction --namespace <namespace>`, where the namespace is the relevant namespace for migration. As this is a bash script, remember to quote the `\` (`\` must become `\\` in your command).

Each bundle has his own namespace for migration (always ask me to confirm that command with a list of updated / created entities so that I can confirm to you that it is ok):

- `Chill\Bundle\ActivityBundle` writes migrations to `Chill\Migrations\Activity`;
- `Chill\Bundle\BudgetBundle` writes migrations to `Chill\Migrations\Budget`;
- `Chill\Bundle\CustomFieldsBundle` writes migrations to `Chill\Migrations\CustomFields`;
- `Chill\Bundle\DocGeneratorBundle` writes migrations to `Chill\Migrations\DocGenerator`;
- `Chill\Bundle\DocStoreBundle` writes migrations to `Chill\Migrations\DocStore`;
- `Chill\Bundle\EventBundle` writes migrations to `Chill\Migrations\Event`;
- `Chill\Bundle\CalendarBundle` writes migrations to `Chill\Migrations\Calendar`;
- `Chill\Bundle\FamilyMembersBundle` writes migrations to `Chill\Migrations\FamilyMembers`;
- `Chill\Bundle\FranceTravailApiBundle` writes migrations to `Chill\Migrations\FranceTravailApi`;
- `Chill\Bundle\JobBundle` writes migrations to `Chill\Migrations\Job`;
- `Chill\Bundle\MainBundle` writes migrations to `Chill\Migrations\Main`;
- `Chill\Bundle\PersonBundle` writes migrations to `Chill\Migrations\Person`;
- `Chill\Bundle\ReportBundle` writes migrations to `Chill\Migrations\Report`;
- `Chill\Bundle\TaskBundle` writes migrations to `Chill\Migrations\Task`;
- `Chill\Bundle\ThirdPartyBundle` writes migrations to `Chill\Migrations\ThirdParty`;
- `Chill\Bundle\TicketBundle` writes migrations to `Chill\Migrations\Ticket`;
- `Chill\Bundle\WopiBundle` writes migrations to `Chill\Migrations\Wopi`;

Once created the, comment's classes should be removed and a description of the changes made to the entities should be added to the migrations, using the `getDescription` method. The migration should not be cleaned by any artificial intelligence, as modifying this migration is error prone.

### Guidelines related to code structure and requirements

#### Usage of clock

When we need to use a DateTime or DateTimeImmutable that need to express "now", we prefer the usage of
`Symfony\Component\Clock\ClockInterface`, where possible. This is usually not possible in doctrine entities,
where injection does not work when restoring an entity from a database, but usually possible in services.

In test, we use `\Symfony\Component\Clock\MockClock` which is an implementation of `Symfony\Component\Clock\ClockInterface`
where we have full and easy control of the date.

### Testing Information

The project uses PHPUnit for testing. Each bundle has its own test suite, and there's also a global test suite at the root level.

#### Use of mock in tests

##### General mocking

For creating mock, we prefer using prophecy (library phpspec/prophecy).

##### Useful helpers and tips that avoid creating a mock

Some notable implementations that are test helpers and avoid creating a mock:

- `\Psr\Log\NullLogger`, an implementation of `\Psr\Log\LoggerInterface`;
- `\Symfony\Component\Clock\MockClock`, an implementation of `Symfony\Component\Clock\ClockInterface` (already mentioned above);
- `\Symfony\Component\HttpClient\MockHttpClient`, an implementation of `\Symfony\Contracts\HttpClient\HttpClientInterface`;
- When using `\Symfony\Component\Mailer\MailerInterface`, we can create the mock with "InMemoryTransport":

    ```php
    use Symfony\Component\Mailer\Transport\InMemoryTransport;
    use \Symfony\Component\Mailer\Mailer;

    $transport = new InMemoryTransport();
    $mailer = new Mailer($transport);

    // After sending:
    $messages = $transport->getSent(); // array of SentMessage
    ```
- When using `\Symfony\Contracts\EventDispatcher\EventDispatcherInterface`, we can use directly an instance of `\Symfony\Component\EventDispatcher\EventDispatcher`;

##### When we prefer not creating a mock

- When we use Doctrine Entities related to the project, we prefer not to use a mock: we instantiate them directly (unless it requires too much code to write);

##### Mocking final and readonly classes

Classes marked as final can't be mocked. To avoid that, either:

- we remove the `final` keyword from the class;
- we extract an interface from the final class.

This must be a decision made by a human, not by an AI. Every AI task must abort with an explicit message in that case.

#### Running Tests

The tests are run from the project's root (not from the bundle's root: so, do not change the directory to any bundle directory before running tests).

Tests must be run using the `symfony` command:

```bash

# Run a specific test file
symfony composer exec phpunit -- path/to/TestFile.php

# Run a specific test method
symfony composer exec phpunit -- --filter methodName path/to/TestFile.php
```

When writing tests, only test specific files. Do not run all tests or the full
test suite.

#### Test Structure

Tests are organized by bundle and follow the same structure as the bundle itself:

- Unit tests: Test individual components in isolation
- Integration tests: Test components working together
- Functional tests: Test the application from the user's perspective

#### Writing Tests

Tests should be placed in the appropriate bundle's test directory. For example, tests for the TicketBundle should be placed in `src/Bundle/ChillTicketBundle/tests/`.

Here's an example of a simple entity test:

```php
<?php

namespace Chill\TicketBundle\Tests\Entity;

use Chill\TicketBundle\Entity\Ticket;
use PHPUnit\Framework\TestCase;

class TicketTest extends TestCase
{
    public function testGetAndSetExternalRef(): void
    {
        $ticket = new Ticket();
        $externalRef = 'REF-123';

        // Set the external reference
        $ticket->setExternalRef($externalRef);

        // Verify that getExternalRef returns the correct value
        self::assertSame($externalRef, $ticket->getExternalRef());

        // Change the external reference
        $newExternalRef = 'REF-456';
        $ticket->setExternalRef($newExternalRef);

        // Verify that getExternalRef returns the updated value
        self::assertSame($newExternalRef, $ticket->getExternalRef());
    }
}
```

#### Test Database

For tests that require a database, the project uses a postgresql database filled with fixtures (usage of doctrine-fixtures). You can configure a different database for testing in the `.env.test` file.

### Code Quality Tools

The project uses several tools to maintain code quality:

#### PHP Code Style

The project uses PHP-CS-Fixer for code style. You can run it with:

```bash
# Using the composer script
composer php-cs-fixer

# Or directly
php-cs-fixer fix --config=./.php-cs-fixer.dist.php
```

#### Static Analysis

The project uses PHPStan for static analysis. You can run it with:

```bash
# Using the composer script
composer phpstan

# Or directly
vendor/bin/phpstan analyse
```

#### Automated Refactoring

The project uses Rector for automated refactoring. You can run it with:

```bash
# Using the composer script
composer rector

# Or directly
vendor/bin/rector
```

#### JavaScript/TypeScript Linting

The project uses ESLint for JavaScript/TypeScript code quality. You can run it with:

```bash
yarn run eslint
```

## Deployment

The project can be deployed in a production environment following Symfony's deployment guidelines. The documentation provides detailed instructions for setting up a production environment.
