Here’s a high-level tour of this codebase: 1. Overall • A Symfony 7.2 “full-stack” PHP web application • Backend in PHP 8.2, frontend in modern ES modules + Stimulus + Turbo + importmap • Uses Doctrine ORM + Migrations for data persistence • Packaged/deployed via Docker (Dockerfile + docker-compose) 2. Backend (“src/” + “config/”) • src/ – your PHP application code (Controllers, Entities, Repositories, Services, Message Handlers, etc.) • config/ – Symfony YAML config (framework, doctrine, security, messenger, mailer, etc.) • migrations/ – Doctrine migration classes to evolve the database • composer.json & symfony.lock – PHP dependencies (Symfony components, Doctrine, Symfony UX/Twig, OpenAI client, ReactPHP, etc.) 3. Frontend (“assets/” + “public/”) • assets/app.js – main JavaScript entrypoint (importmap-driven) • assets/controllers/ – Stimulus controllers (wired up via symfony/stimulus-bundle) • assets/styles/ – your CSS (plain .css processed by Symfony Asset Mapper) • importmap.php – declares which JS packages (Stimulus, Turbo, Three.js, D3, Globe.gl, SweetAlert2, etc.) are available to browsers via importmap • public/ – web-accessible assets & the front controller (public/index.php) 4. Asset pipeline • Uses Symfony Asset Mapper + importmap instead of Webpack/Encore • “symfony-cmd” scripts in composer.json auto-install assets & importmap entries on composer install/update • No heavy bundling step: modules are loaded on-demand in the browser 5. Data & messaging • Doctrine ORM & DBAL for relational database (MySQL/PostgreSQL) • doctrine/doctrine-migrations-bundle to manage schema changes • Symfony Messenger with an async transport (via MESSENGER_TRANSPORT_DSN env) and a “failed” transport backed by the database • Routes email, SMS and chat notifications through Messenger queues 6. Dev, tests & tooling • PHPUnit (phpunit.xml.dist) + symfony/phpunit-bridge for unit/functional tests in tests/ • symfony/maker-bundle to scaffold code • .env files under var/ or project root to configure environment variables • Docker setup under docker/ and root docker-compose.yml for local dev • Pre-commit hooks (if present) to enforce coding style 7. Deployment & docs • Dockerfile for containerizing the app • compose.override.yaml.old (likely local-override); remove or update if you customize • documentation.MD / manifest.md for any project-specific docs
