Let’s get started.


Installation of Laravel Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system,

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project.

If your system doesn’t has composer Installed, Learn Composer Installation Steps.

Here is the complete command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

After following these steps we can install a Laravel application into system.

To start the development server of Laravel –

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel already installed at system.


JSON Data Preparation

Let’s consider a .json file in application. We have a students.json inside /storage folder.

{
"students":[
	{
		"name": "Sanjay Kumar",
		"email": "sanjay@gmail.com"
	},
	{
		"name": "Ashish Kumar",
		"email": "ashish@gmail.com"
	},
	{
		"name": "Dhananjay Negi",
		"email": "dj@gmail.com"
	},
	{
		"name": "Vijay Rohila",
		"email": "vijay@gmail.com"
	}
 ]
}

You can place this .json file either in /storage folder or /public folder. We will read only by specifying the path.


Create Controller

Open project into terminal and run this artisan command.

$ php artisan make:controller SiteController

It will create a file SiteController.php inside /app/Http/Controllers folder.

Assuming /storage folder.

Open SiteController.php and write this complete code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SiteController extends Controller
{
    public function index()
    {
        $students = json_decode(file_get_contents(storage_path() . "/students.json"), true);

        echo "<pre>";
        print_r($students);
    }
}

Concept

$students = json_decode(file_get_contents(storage_path() . "/students.json"), true);

Here, we are parsing students.json file. storage_path() is a Laravel 8 helper function which returns the path upto /storage folder.

If you have taken /public folder then you should use public_path() in place of it. json_decode returns the data in object format. But putting true as second value it returns the data into array format.

Now, we can insert the .json file data into database etc.


Create Route

Open web.php from /routes folder. Add this route into it.

//...

use App\Http\Controllers\SiteController;

Route::get("data", [SiteController::class, "index"]);

//...

Application Testing

Open project to terminal and type the command to start development server

$ php artisan serve

URL: http://127.0.0.1:8000/data
