Features Of Laravel 6

Exploring The Top Features of Laravel 6

By Mohit Surati Laravel March 20, 2020 7 min read 210 Views

Laravel is an open-source, PHP-based framework, which focuses on building web-applications considering Model-View-Controller (MVC) architectural pattern as a key element.

Along with the pattern, the developers can quickly start the project with the use of additional laravel helpers such as strings, paths, URLs, arrays and objects. The developers can make optimum use of it.

Numerous versions of Laravel have been released either with minor or major updates. Also, it comes with enticing features that help in crafting beautiful web apps.

Here, we are going to discuss the features of Laravel 6 that includes:

1. Lazy Collection

Lazy collection turns out to be the go-to tool for the developers and an amazing feature of angular 6. It loads heavy data by using as much low memory as possible. It utilizes the PHP generators that help in reducing the usage of memory. For the ones who are not familiar with the PHP generators can go through the above link.

If you are using an eloquent model with heavy data, then a lazy collection will be a boon for you. This will not only restrict the use of memory but will also help in showing precise information at a time.

Here’s the technical explanation with coding which might help you understand the Lazy collection:

Use cursor() instead of all() to load only one eloquent model at a time will use less memory as compared to loading the whole data at once.

// This loads all eloquent models into memory at the same time

// This may be a very large number if you have thousands of posts

$posts = App\Post::all()->filter(function ($post) {

    return $post->id > 500;


As you can see, the above coding contains all(), which means it will load the entire eloquent model at once, which results in draining a lot of memory. Apart from this, if you utilize cursor(), then only a single model is loaded at a time.

$posts = App\Post::cursor()->filter(function ($post) {

  return $post->id > 500;


foreach ($posts as $post) {

  echo $post->id;


2. Job Middleware

Middleware is a fetching tool that filters HTTP requests that are accessing your apps. Numerous middlewares perform different functions such as database middleware, message-oriented middleware, transaction-processing middleware, and application server middleware.

For example, the application authenticated middleware verifies whether the user has successfully logged into the application or not. If the user has not logged in, then the user will be redirected to the app’s login screen.

Similarly, a CORS middleware adds a suitable header to the responses left on the application. Apart from this, a logging middleware can log the requests to the project.

Let’s see how job middleware performs with coding:

// app/Jobs/JobToBeThrottled.php

// Execute the job

public function handle() {

  // allow one job to process every 5 seconds

  Redis::throttle('key')->block(0)->allow(1)->every(5)->then(function () {

    // Handle the job

  }, function () {

    // Could not obtain lock

    return $this->release(5);



Here, the above coding contains handle() which can be utilized for adding a job. With this, you can add code into a job middleware. Also, if you want to create a directory, then you can create one in app/Jobs/Middleware and you have to add a file in that particular folder.

// app/Jobs/Middleware/RateLimited.php


namespace App\Jobs\Middleware;

use Illuminate\Support\Facades\Redis;

class RateLimited {

  // Process the queued job.

  public function handle($job, $next) {



      ->then(function () use ($job, $next) {

        // Lock obtained


      }, function () use ($job) {

        // Could not obtain lock





If you are familiar with the route middleware, then the process is quite similar. You have to tie the middleware to the job and then it will start processing.

// app/Jobs/JobToBeThrottled.php

use App\Jobs\Middleware\RateLimited;

// get the middleware that the job will use

public function middleware() {

  return [new RateLimited];


public function handle() {

  // handle the job


You can leverage the middleware by reusing it. Also, the middleware possesses benefits such as easily readable, focused and tiny.

3. Subquery Enhancement

In Laravel’s version 5.0, there were a lot of difficulties that developers faced while selecting multiple queries. The new subquery enhancement is an enticing feature of laravel 6. It can run queries with another query, or subqueries in one call. This has relieved a lot of pain of the developers.

addSelect has been a boon to subqueries that has relaxed the developers. The eloquent subqueries can access orderBy.

This will be explained in detail by the following example:

There are two tables: reservations and hotels. Now, if you want to know which room was recently booked from which hotel, then you can do the following:

use App\Reservation;

use App\Hotel;

return Hotel::addSelect(['last_booked_room' => Reservation::select('room_type')

  ->whereColumn('hotel_id', 'hotels.id')

  ->orderBy('created_at', 'desc')




By implementing the code mentioned above, you would be able to know your required result.

4. Semantic Versioning

With the release of the latest version, i.e., 6, laravel confirms the support of Semantic Versioning. It makes a smooth and consistent rapport with first-party packages of the framework. The previous versions were restricted for modification and rewriting of new releases. But, with the new version, there is no need to worry about the changes in the frameworks.

5. Laravel Vapor

It is one of the user-engaging features of laravel 6 that is compatible and delivers desired results. It is an auto-scaling deployment platform without a server that can work well with laravel 6.

The function of laravel vapor is to separate the complexities of the apps on AWS Lambda. Along with the AWS Lambda, it interfaces apps with databases, CloudFront CDN and many more.

6. Authorization

It was an arduous task in the previous version of laravel to convey the error message and the reason behind the denial of a particular request. But, since the release of laravel 6, it has become a boon for the developers.

The new Gate::inspect has made it a lot easier in authorizing the messages to the users. Let’s understand it through an example:


 * Determine if the user can view the given flight.


 * @param  \App\User  $user

 * @param  \App\Flight  $flight

 * @return mixed


public function view(User $user, Flight $flight)


    return $this->deny('Explanation of denial.');


You can easily retrieve the authorization policy response and message by using Gate: :inspect:  

$response = Gate::inspect('view', $flight); 

if ($response->allowed()) {

    // User is authorized to view the flight...


if ($response->denied()) {

    echo $response->message();


If you are using a helper method like $this->authorize OR Gate::authorize from routes or controller, then you can easily return the messages to the client-side.

7. Laravel User Interface

Laravel/ui is a composer package where the client-side scaffolding has been stored. This results in a separate development of the first-party UI from the main framework. The make: auth has also been removed out from the framework.

If you want to install the Vue/Bootstrap scaffolding, then you have to install the laravel/ui package and utilize ui artisan command for installing client-side scaffolding.

composer require laravel/ui --dev

php artisan ui vue --auth
