Getting Started
---------------

[](#getting-started)

### Requirements

[](#requirements)

- PHP >= 7.2
- URL Rewriting

### Installation

[](#installation)

Using Composer:

```
$ composer create-project davidecesarano/embryo [my-app-name]

```

### Configuration

[](#configuration)

Embryo utilizes the [DotEnv](https://github.com/vlucas/phpdotenv) PHP library. In a fresh Embryo installation, the root directory of your application will contain a `.env.example` file. When you install Embryo via Composer, this file will automatically be renamed to `.env`.

### Directory Structure

[](#directory-structure)

DirectoryDescriptionappContains the core code of your application. This directory contains a variety of additional directories such as `Controllers`, `Exceptions`, `Helpers`, `Middleware`, `Models` and `Services`.bootstrapContains the files which bootstraps your application such as app instantiation, middleware, services and settings.publicContains the entry point for all request (`index.php` file) and the `assets` directory.routesContains all of the route definitions for your application. By default, several route files are included with Embryo: `app.php` and `api.php`.storageContains your logs (`logs`), compiled templates file (`views`), file based sessions (`sessions`), caches files (`cache`).translationsContains your language files.viewsContains the views files.Concepts
--------

[](#concepts)

### Life Cycle

[](#life-cycle)

- The app is instantiated in `bootstrap/app.php` with `Embryo\Application` class. During instantiation, Embryo registers services for the dependencies (`bootstrap/services.php`), middlewares (`bootstrap/middleware.php`) and routes files (in `routes` directory). The application constructor accepts an optional settings array that configures the application’s behavior (`bootstrap/settings.php`).
- In `routes` direcotry define routes using the application instance’s routing methods. These instance methods register a route with the application’s Router object. Each routing method returns the Route instance so you can immediately invoke the Route instance’s methods to add middleware or assign a name.
- In `public/index.php` invoke the application instance's `run()` method. This method starts the following process:
    - enter in middleware stack;
    - run application (dispatches the current HTTP request to the appropriate application route object);
    - exit middleware stack;
    - send HTTP response.

### PSR-7

[](#psr-7)

Embryo supports [PSR-7](https://www.php-fig.org/psr/psr-7/) interfaces for its Request and Response objects.

### Middleware

[](#middleware)

You can run code before and after your Embryo application to manipulate the Request and Response objects as you see fit. This is called middleware. A middleware implements the [PSR-15 Middleware Interface](https://www.php-fig.org/psr/psr-15/).

### Dependency Container

[](#dependency-container)

Embryo uses an dependency container to prepare, manage, and inject application dependencies. Embryo supports containers that implement [PSR-11](http://www.php-fig.org/psr/psr-11/).

Application
-----------

[](#application)

### Routing

[](#routing)

You can define application routes using the application instance’s routing methods. Every method accepts two arguments:

- The route pattern (with optional placeholders)
- The route callback (a closure, a `class@method` string or a `['class', 'method']` array)

```
use Embryo\Http\Message\{Response, ServerRequest};

// GET Route
$app->get('/blog/{id}', function(ServerRequest $request, Response $response, int $id) {
    return $response->write('This is post with id '.$id);
}
```

Embryo Routing supports GET, POST, PUT, PATCH, DELETE and OPTIONS request methods. Every request method corresponds to a method of the Router object: `get()`, `post()`, `put()`, `patch()`, `delete()` and `options()`. You can use `all()` and `map()` methods for supporting all methods or specific route methods.

See full documentation: [Embryo Routing](https://github.com/davidecesarano/Embryo-Routing#usage).

#### Register route files

[](#register-route-files)

All Embryo routes are defined in your route files, which are located in the `routes` directory. These files are automatically loaded by your application in `boostrap/app.php` file. If you want create new ruote file, add it in routes directory and register it in `import()` method of the application instance in `boostrap/app.php` file:

```
$app->import([
    root_path('bootstrap/services.php'),
    root_path('bootstrap/middleware.php'),
    root_path('routes/api.php'),
    root_path('routes/app.php'),
    root_path('routes/my_route_file.php')
]);
```

### Middleware

[](#middleware-1)

In Embryo you may create a PSR-15 middleware in `app\Middleware` directory. You may add middleware to application, to specific route or to route group.

#### Application middleware

[](#application-middleware)

If you want register middleware for every HTTP request, add application middleware in `bootstrap\middleware.php`. The `addMiddleware()` method accepts a string, an array or an instance of `Psr\Http\Server\MiddlewareInterface`.

```
$app->addMiddleware(App\Middleware\MyCustomMiddleware::class);
```

#### Route middleware

[](#route-middleware)

You can use the `middleware()` method to assign one or more middleware at the route. The `middleware()` method accepts a string, an array or an instance of `Psr\Http\Server\MiddlewareInterface`.

```
$app->get('/users', function(ServerRequest $request, Response $response) {
    //...
})->middleware('App\MiddlewareTestMiddleware1::class', 'App\MiddlewareTestMiddleware2::class');
```

#### Route group middleware

[](#route-group-middleware)

In addition to the routes, you can assign one or more middleware to a group and to individual routes within the group. The `middleware()` method accepts a string, an array or an instance of `Psr\Http\Server\MiddlewareInterface`.

```
$app->prefix('/api')->middleware(App\Middleware\GroupMiddlewareTest::class)->group(function($app) {
    $app->get('/user/{id}', function(ServerRequest $request, Response $response, int $id) {
        //...
    })->middleware(App\Middleware\RouteMiddlewareTest::class);
});
```

### Controllers

[](#controllers)

Instead of defining all of your request handling logic as closures in your route files, you may wish to organize this behavior using "controller" classes. Let's take a look at an example of a basic controller. Note that the controller extends the base controller class included with Embryo:

```
namespace App\Controllers;

use Embryo\Controller;
use Embryo\Http\Message\Response;

class UserController extends Controller
{
    /**
     * @param int $id
     * @return Response
     */
    public function show(int $id): Response
    {
        return $this->response()->write($id);
    }
}
```

You can define a route to this controller method like so:

```
use App\Controllers\UserController;

$app->get('/user/{id}', [UserController::class, 'show']);
```

Controllers are **required** to extend a base class. However, you will not have access to features such as the `get()`, `request()` and `response()` methods.

#### Dependency Injection & Controllers

[](#dependency-injection--controllers)

You are able to type-hint any dependencies your controller may need in its constructor. The declared dependencies will automatically be resolved and injected into the controller instance:

```
namespace App\Controllers;

use Embryo\Controller;
use Path\To\Service;

class UserController extends Controller
{
    /**
     * @var Service $service
     */
    private $service;

    /**
     * @param Service $service
     */
    public function __construct(Service $service)
    {
        $this->service = $service;
    }
}
```

In addition to constructor injection, you may also type-hint dependencies on your controller's methods:

```
namespace App\Controllers;

use Embryo\Controller;
use Embryo\Http\Message\ServerRequest;

class UserController extends Controller
{
    /**
     * @param ServerRequest $request
     */
    public function store(ServerRequest $request)
    {
        //...
    }
}
```

In addition, you may also to use the `get()` method of the base controller class:

```
namespace App\Controllers;

use Embryo\Controller;
use Path\To\Service;

class UserController extends Controller
{
    public function show()
    {
       $service = $this->get(Service::class);
       //...
    }
}
```

Base controller class also has access to PSR-7 `request()` and `response()` methods:

```
namespace App\Controllers;

use Embryo\Controller;
use Embryo\Http\Message\Response;

class UserController extends Controller
{
    /**
     * @return Response
     */
    public function store(): Response
    {
       $params = $this->request()->getParsedBody();
       //...
       return $this->response()->write('Hello!');
    }
}
```

Alternatively, you may to access to `request()` and `response()` helpers:

```
namespace App\Controllers;

use Embryo\Controller;
use Embryo\Http\Message\Response;

class UserController extends Controller
{
    /**
     * @return Response
     */
    public function store(): Response
    {
       $params = request()->getParsedBody();
       return response()->write('Hello!');
    }
}
```

### Service Providers

[](#service-providers)

Service providers are the central place of all Embryo application bootstrapping. Your own application, as well as all of Embryo's core services, are bootstrapped via service providers.

#### Writing a service

[](#writing-a-service)

The service providers era located in `app/Services` directory. All service providers extend the `Embryo\Container\ServiceProvider` class and contains a `register` method. Within the register method, you should only bind things into the service container.

```
namespace App\Services;

use Embryo\Container\ServiceProvider;

class TestService extends ServiceProvider
{
    /**
     * Registers service provider.
     *
     * @return void
     */
    public function register()
    {
        $this->container->set('test', function($container){
            return 'Hello from my test service';
        });
    }
}
```
