Laravel-8.6.0-Development

PHP framework that follows a robust MVC (Model-View-Controller) pattern to increase productivity. It was first released in 2011 and has been impacting the market and steadily growing since then. Many people hire dedicated Laravel developers because it has unique features and functionalities for the digital world. 

Some noteworthy features of Laravel:

Eloquent Object-Relational Model

This pattern allows us to present database tables as a class. This means that you can define a class that will be tied to your database. Eloquent allows you to select complicated queries from the database using class functions.

Views with Blade

 The View section contains all the HTML code used in the application that means there is no need to combine the business logic with the presentation layer. Blade tempting engine is supported by Views that allows writing reusable code of HTMS and generic layout files. 

Controllers

Using controllers you can group the related request handling logic into a single class.

Authentication

Completing the authentication mechanism takes only two steps:

  • php artisan make: auth
  • php artisan migrate

Laravel is not like other web applications that implement authentication systems instead it comes free.  

Template Engine 

Laravel has built-in templates that are used in building layout by using dynamic content seeding. It has multiple widgets with JavaScript and CSS code in a robust structure. Laravel Development Company has the freedom to create simple and complex layouts using distinctive sections. 

Security

Web application security is very important in the digital world and is expected from every online platform. Laravel framework uses salted and hashed mechanisms for a password that means it will never save the data in plain text. PHP web development framework works on prepared SQL statements to prevent SQL injection attacks and also uses the Bcrypt Hashing algorithm to generate an encrypted password.    

Routing

Laravel gives a simple routing mechanism and builds a list that is present in one file and makes the route convenient to access. You can have multiple files for bigger applications that support API. You can add @csrf annotation to your form to protect it from CSRF (Cross-Site Request Forgery) attack.    

Release notes

What’s new in Laravel 8.6.0?

Model Directory

With Laravel 8 the app/Models folder will be included by default. Even if you don’t want the Models directory and delete the app/Models directory, then the artisan command will add the new model in the app/ directory directly.

Route Caching Improved

A big PHP array has the collection of all the routes which makes the platform more efficient and faster. Previously if the routes had closure, the route caching won’t work but with the update, the route caching works fine with closure.

Improved Maintenance Mode

There have been improvements in the PHP artisan down command. Instead of using the IP white list you can use a secret and configure the platform maintenance mode:

php artisan down –secret=SECRET_CODE 

Add a secure string in place of SECRET_CODE and access the site in maintenance mode you need to visit:

Yourdomainname.com/SECRET_CODE 

This generates a secret cookie that allows you to browse the website normally and gives a great way to add the website in maintenance mode while accessing it through secret code. 

Another addition is you could pre-render the maintenance page and even if the composer update runs, still the end-users will see the maintenance page instead of errors.

Run the below code:

php artisan down –render =” errors::503” 

Now you can run the command to add secret in the rendered the page and change the status code at the same time:

php artisan down –render=”errors::503” –status=200 –secret=SECRET_CODE

Rate Limit Improvements

The rate limit in Laravel 8 is more flexible and compatible with the previous release throttle middleware API. This makes handling the request easier and limits the number of requests sent per minute by users. 

Schema Dump

You can generate a schema file in the database/schema directory using the artisan command:

php artisan schema: dump  

Dump your current database schema and prune the existing migrations by:

php artisan schema: dump –prune

It will remove the old migrations and generate a single schema dump file. 

Laravel Jetstream

It is a free and open-source application scaffolding for Laravel. It has components like:

  • Email Verification
  • Registration and login functionality
  • Two-factor authentication
  • API support
  • Session management

Job Batching

The latest update allows running a batch of jobs and running action once the batch of the job is executed.

New Landing Page

The page gets displayed when you click on the homepage in a fresh install and has light/dark versions. It also has links to the SaaS product and community site of Laravel.  

Controllers namespace prefix

The previous version had RouteServiceProvider.php called $namespace that is used as the prefix of the namespace of your controllers automatically. This property has been removed and you can import the controller classes in the route file without any issue. 

Queue able Anonymous event listener

Earlier you had to create event class and event listener using the ShouldQueue trait but with the new feature introduces the first namespace function in the Laravel framework:

Illuminate\Events\queueable

You will be able to send the closure bases job to queue from model event callbacks faster.

Exponential Backoff for the Job failure 

Add a new backoff() method to job classes that return the array of integers to decide wait time in between the job attempts when it fails.
