Create a controller in laravel.

To create a controller using the syntax: 

λ php artisan make: controller ControllerName

Creating some function which returns a string or a view. 

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PagesController extends Controller

{

    public function root()

    {

        return view('welcome'); //return a view

    }

    public function about()

    {

        $name ="Dev"; // declaring a varibale and assigning a value to the varibale 

        return view ('about')->with('name', $name); // passing data to the view 

  with ('name ', $varibale)

    }

    public function contact()

    {

        

        return 'contact'; //return a string

    }

}

let's check the route as well as how we define the routes?

Route::get('/', 'PagesController@root');

 Route::get('contact', 'PagesController@contact');

 Route::get('about', 'PagesController@about');

so when you hit localhost:8000 (port may differ as per your config) this will return

Welcome page

let's create a welcome page first so go to the view directory create a file

welcome.blade.php by default this page generated during installation so you can simply

edit the page as per your choice.

 <div class="title m-b-md">

    Welcome to code factory 20-21 

 </div>

How to pass data to the view from the route in Laravel ??

 We can pass the data to the view using help function 

1. with ( )
2. compact ( )

Using With 

Route::get('/greet', function () {

   $name = 'Dev';

    // declaring and assigning a value to the variable 

    return view ('greeting')->with('name', $name); // pass the variable to the view 

});

how to define a route ??

 locate the route file web.php in side the route directory of the project 

Basic Route which returns a value 

Route::get('/greeting', function () {
    return 'good morning';
});

output on the browser

Basic Route which returns a view  

Route::get('/greeting', function () {
    return view ('greeting');
});
To return a view we need to create  a view first other wise it throw an error view not found
 To create a view locate the view folder and create a file greeting.blade.php
