Supports PHP 8.1+ and composer

TL;DR

Quick-Jump into develop:

Open your browser on: http://localhost:3333

Look into files:

• app config and wiring
• assemble.php composer autoload, gathers configurations and creates the system modules from that config
• launch.php runs assemble() and dispatches the SatelliteApp event
• app folder with a basic commands and route handler structure

Setup

Install app skeleton and dependencies with composer in folder satellite:

Run with:

• Linux, PHP Dev Server
• PHP Command-Line
• Docker, docker-compose
• Web-Server

Linux, PHP Dev Server

Setup correct user rights, then start and open http://localhost:3333

PHP Command-Line

Execute defined commands.

Docker, docker-compose

Includes configurable PHP Dockerfile with:

• PHP 8.1
  • with FPM and a few extensions
  • reusing FPM for a clean CLI worker image
• OPCache
• PostgreSQL Client libs (using pdo)
• NGINX base image for local routing
• customize in Dockerfile
• a more "production" ready image, preconfigured for building docker-compose--prod.yml

For docker image configs see files in _nginx.

Start containers specified in http://localhost:3333

Web-Server

On a web-server the web/index.php file serves as public entry point.

Apache: point server/vhost root to /web and use the included .htaccess

NGINX: example files in _nginx.

Config

Use e.g. .env to add configuration.

Default's config includes:

• env var env: if in production or not in production
  • with value prod it is assumed in the App (not the framework) that it is in production
  • use $_ENV['env'] === 'prod' to check for production
  • for dev-error pages: add var dev.editor with one value of PrettyPageHandler::EDITOR_* to link whoops "open file" with IDE
• /config/config.php - main config
  • configures which other config files are included
  • aggregates and caches the config for production usage
• /config/dependencies.php - definitions for PHP-DI
• /config/events.php - define app components flow
• /config/pipeline.php - setup PSR middlewares and pipeline

PSRs

This app serves as mini-framework, with PSR powered libraries, ready-to-use Annotations and not much more.

It is build upon PSRs and popular, specialized packages implementing them or other great stuff.

• PSR-3 - Logger
  • 📦 monolog/monolog
  • more implementations
• PSR-4 - autoload classes and forget require_once
  • handled by composer, more in composer docs.
• PSR-1,12 - Code Style Guides
  • except brackets location rule: same-line instead of next-line for opening {
• PSR-6 - Cache
  • 📦 cache/filesystem-adapter
  • includes FilesystemCachePoolNormalized for Doctrine\Common\Annotations\PsrCachedReader compatibility
  • more implementations
• PSR-7 - HTTP Message
  • 📦 nyholm\psr7
  • request and response data definitions
  • used further by PSR-15, PSR-17 and PSR-18
• PSR-11 - Container for InterOp
  • 📦 php-di/php-di
  • service container for ease and modularity
  • dependency injection with @Annotations, @var PHPDoc and Reflection support
• PSR-14 - Event Dispatcher and Listener
  • 📦 orbiter/satellite
  • as the core of how things are put together
• PSR-15 - HTTP Handlers
  • 📦 orbiter/satellite-response
  • handle route requests with a powerful middleware pipeline
• PSR-16 - Simple Cache
  • 📦 cache/filesystem-adapter
  • more implementations
• PSR-17 - HTTP Factories
  • 📦 nyholm\psr7
  • context about request
  • for request & response initiations
• PSR-18 - HTTP Client
  • 📦 guzzlehttp/guzzle
  • send requests to other APIs
  • more implementations

📦 = included in satellite-app template

A lot of work for APIs is done by PSR-15 HTTP Middleware, find more awesome middlewares.

Download Build

There is no downloadable version - see Setup on how to install with composer.

We use composer as package manager, like in any modern PHP project.
