Scrawler Router

🔥An Fully Automatic, Framework independent, RESTful PHP Router component🔥
🇮🇳 Made in India 🇮🇳

🤔 Why use Scrawler Router?

• Fully automatic, you dont need to define single manual route.
• No configrations , works out of the box with any php project.
• Stable and used internally within many Corpuvision's projects
• Saves lot of time while building RESTful applications
  
  

💻 Installation

You can install Scrawler Router via Composer. If you don't have composer installed , you can download composer from here

composer require scrawler/router

✨ Setup

<?php

use Scrawler\Router\RouteCollection;
use Scrawler\Router\Router;
use Symfony\Component\HttpFoundation\Response;


$dir = /path/to/your/controllers;
$namespace = Namespace\of\your\controllers;

$router = new Router(new RouteCollection($dir,$namespace));
//Optional you can now pass your own Request object to Router for Router to work on
//$router = new Router(new RouteCollection($dir,$namespace),Request $request);


//Dispatch route and get back the response
$response = $router->dispatch();

//Do anything with your Response object here
//Probably middleware can hook in here

//send response
$response->send();

Done now whatever request occurs it will be automatically routed . You don't have define a single route

🦊 How it Works?

The automatic routing is possible by following some conventions. Lets take a example lets say a controller Hello

<?php
//Hello.php

class Hello
{
    public function getWorld()
    {
        return "Hello World";
    }
}

now calling localhost/hello/world from your browser you will see hello world on your screen.

🔥 How does it do it automatically?

Each request to the server is interpreted by Scrawler Router in following way:

METHOD /controller/function/arguments1/arguments2

The controller and function that would be invoked will be

<?php

class Controller
{
    public function methodFunction($arguments1, $arguments2)
    {
        //Definition goes here
    }
}

For Example the following call:

GET /user/find/1

would invoke following controller and method

<?php

class User
{
    public function getFind($id)
    {
        //Function definition goes here
    }
}

In above example 1 will be passed as argument $id

⁉️ How should I name my function for automatic routing?

The function name in the controller should be named according to following convention: methodFunctionname Note:The method should always be written in small and the first word of function name should always start with capital. Method is the method used while calling url. Valid methods are:

all - maps any kind of request method i.e it can be get,post etc
get - mpas url called by GET method
post - maps url called by POST method
put - maps url called by PUT method
delete - maps url called by DELETE method

Some eg. of valid function names are:

getArticles, postUser, putResource

Invalid function names are:

GETarticles, Postuser, PutResource

🏠 Website home page

Scrawler Router uses a special function name allIndex() and special controller name Main. So If you want to make a controller for your landing page \ the controller will be defines as follows

// Inside main.php
class Main
{
    // All request to your landing page will be resolved to this controller
    // ALternatively you can use getIndex() to resolve only get request
    public function allIndex()
    {
    }
}

🌟 Main Controller

Class name with Main signifies special meaning in Scrawler Router , if you wanna define pages route URL you can use main controler

// Inside main.php
class Main
{
    // Resolves `/`
    public function getIndex()
    {
    }
    
    // Resolves `/abc`
    public function getAbc()
    {
    
    }
    
    // Resolves `/hello`
    public function getHello()
    {
    
    }
}

👉 Index function

Just like Main controller allIndex(), getIndex(), postIndex() etc signifies a special meaning , urls with only controller name and no function name will try to resolve into this function.

// Inside hello.php
class Hello
{
    // Resolves `/hello`
    public function getIndex()
    {
    
    }
    
    // Resolves `/hello/abc`
    public function getAbc()
    {
    
    }
}

🖥️ Server Configuration

Apache

You may need to add the following snippet in your Apache HTTP server virtual host configuration or .htaccess file.

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php)
RewriteRule ^(.*)$ /index.php/$1 [L]

Alternatively, if you’re lucky enough to be using a version of Apache greater than 2.2.15, then you can instead just use this one, single line:

FallbackResource /index.php

IIS

For IIS you will need to install URL Rewrite for IIS and then add the following rule to your web.config:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rule name="Toro" stopProcessing="true">
                <match url="^(.*)$" ignoreCase="false" />
                <conditions logicalGrouping="MatchAll">
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                    <add input="{R:1}" pattern="^(index\.php)" ignoreCase="false" negate="true" />
                </conditions>
                <action type="Rewrite" url="/index.php/{R:1}" />
            </rule>
        </rewrite>
    </system.webServer>
</configuration>

Nginx

Under the server block of your virtual host configuration, you only need to add three lines.

location / {
  try_files $uri $uri/ /index.php?$args;
}
