README

Simple php framework will be useful for creating provisional endpoints in frontend development.

Start

Create entrypoint for you scripts and define configuration as mentioned in the next part

<?php
require_once __DIR__ . '/vendor/autoload.php';

try {
    $app = new \Zaek\Framy\App([
        'homeDir' => __DIR__,
        'routes' => [
            'GET /' => '/web/Index.php',
        ]
    ]);
    $app->handle();
    $app->response()->flush();

} catch (\Exception $e) {
    echo $e->getMessage();
}

Routing

You can overwrite default router calling the setRouter method

\Zaek\Framy\App::setRouter(\Zaek\Framy\Router)

Router syntax:

[
  '[METHOD[:RESPONSE_TYPE] ]URI' => TARGET
] 

Method

Method must be one of the following: GET|HEAD|POST|PUT|DELETE|CONNECT|OPTIONS|TRACE|CLI
Skip the method definition mean that URI is accessible by any of knowing methods

Response type

You could specify response type

html|json

URI

URI may be static...

/api/testCall

...or dynamic

/api/<dynamicGroup>

where dynamic group defines with the expression:

variable:regex
variable - any latin symbol
regex - regular expression rule

Example:
/api/user<userId:[\d]+> 
(converts by framework to #/api/user(?<userId>[\d]+)#)

Target

Target can be a callback function, an array contains function name, an array with class name and method name (method must be static for class names not object), or an object implements \Zaek\Framy\Action interface

Examples

[
  '/api/staticCall' => '/Web/Index.php',
  'GET:json|CLI /api/runCron' => '/Cli/Job.php',
  '/api/users/<userId:[\d]+>' => '/Web/User.php', // access to $userId from $this->request()->getQuery('userId')
  '/api/functionCall' => function(Controller $app) : Action {},
  '/api/methodCall' => ['MyController', 'MethodAction'], // Вызывается непосредственно для получения Action
  '/api/anotherFunction' => ['FunctionName'], // Вызывается непосредственно для получения Action
  '/api/actionCall' => new Zaek\Framy\Action\Action,
  '/api/absolutePathFileCall' => '@/var/www/index.html',
]

REST

REST route creates following links:

new Router(['REST /projects' => '/api/projects/']);

[
    'GET:json /projects' => '/api/projects/List.php',
    'POST:json /projects' => '/api/projects/Add.php',
    'GET:json /projects/<project_id:[\d]+>' => '/api/projects/Item.php',
    'PATCH:json /projects/<project_id:[\d]+>' => '/api/projects/Update.php',
    'DELETE:json /projects/<project_id:[\d]+>' => '/api/projects/Delete.php',    
]

Route key uses as route key e.g. for /projects is project_id, for /users is user_id etc.

Prefix

For grouping URIs by prefix you can use class RoutePrefix:

new Router(new RoutePrefix('/api', [
    '/users' => '/users.php',
    '/settings' => '/v.php'
]));

// Is the same as

new Router([
    '/api/users' => '/users.php',
    '/api/settings' => '/settings.php'
]);

RoutePrefix handles as array, so you can group prefixes inside other prefix and combine RoutePrefix with standard route:

new Router([
    ...new RoutePrefix('/api', [
        '/settings' => '/settings.php',
        ...new RoutePrefix('/users', [
            'GET /' => '/users_list.php',
            ...new RoutePrefix('/auth', [
                'POST /login' => '/login.php',
                'POST /logout' => '/logout.php',
            ])
        ])
    ])),
    ...new RoutePrefix('/catalog', ['/' => '/catalog.php']),
    '/' => '/index.php'
]);

Example for versioning:

$routes = new RoutePrefix('/users', ['GET /' => '/users.php']);

$v1 = new RoutePrefix('/v1', ['GET /version' => '/v1.php', ...$routes]);
$v2 = new RoutePrefix('/v2', ['GET /version' => '/v2.php', ...$routes]);
$v3 = new RoutePrefix('/v3', ['GET /version' => '/v3.php', ...$routes, ...['GET /users/' => '/users_change.php']]);

$router = new Router(new RoutePrefix('/api', [
    ...$v1,
    ...$v2,
    ...$v3,
]));

// /api/v1/users => /users.php
// /api/v2/users => /users.php
// /api/v3/users => /users_changed.php

Proxy

Proxying all responses in group with a callback:

$proxyCallback = function($route) {
    return new CbFunction(function(App $app) use($route) {
        if($app->user()->getId() < 1) {
            throw new Exception('No auth', 401);
        }

        return new File($route);
    });
};

/// The request /api/user/data and /api/personal/data will be proxy by proxyCallback
///     and will throw an exception for non-authorized users

new Router(new RoutePrefix('/api', [
    '/data' => '/data.php',
    // It could be the proxy inside a group as a group inside the proxy 
    ... new RoutePrefix('/user', new RouteProxy($proxyCallback, [
        'GET /data' => '/user_data.php',
    ])),
    ... new RouteProxy($proxyCallback, new RoutePrefix('/personal', [
        'GET /data' => '/user_personal.php',
    ]))
]))

Config

Name	Type	Default Value	Description
homeDir	string	$_SERVER['DOCUMENT_ROOT']	The root directory of web server
routes	array	-	List of routing rules will be applyed
dataDir	string	-	The directory where will be store all data (built-in file-based DB)
useDefault	bool	true	Use default framework settings (see below in section default setup)

Default setup

The default functionality provided by Framy will place:

User with the following properties

id = 10012019
login = 'framy'
email = '[e-mail]'

Status=ok in JSON response

Every action has JSON response will be complete with {status:'ok'} flag

Routes to api

Built-in sign-up action is placed in ./bin directory. The useDefault option will add the route to such script.

Built-in API

URI	Method	Params	Return
/framy/signUp	POST	login password email	{userId:(int)}
