Laravel Airlock

Laravel Airlock is the official package for API authentication. It provides simple token-based API authentication, token issuance, token capabilities, mobile app authentication, and more.

Zttp for HTTP Client

Using Zttp, making HTTP requests to the API would be a better and more concise approach.

Post request

<?php
use Illuminate\Support\Facades\Http;
$response = Http::post($url);
$response = Http::post($url, [
    &#39;site&#39; => &#39;Laravel Article&#39;,
]);

Get response

$response = Http::get($url);
$response = Http::get($url,['foo'=>'bar']);

With request header

$response = Http::withHeaders(['foo' => 'bar'])->post($url, [
    'baz' => 'qux',
]);

Response

$response['foo']
$response->body()
$response->json()
$response->status()
$response->ok()

CORS support

Laravel 7 now supports CORS (Cross-Origin Resource Sharing) out of the box. You should better understand that every developer has encountered CORS issues in API development. Laravel 7 now automatically responds to OPTION requests using configuration values. Laravel 7 comes with HandleCors middleware out of the box that does it all.

Custom Eloquent Cast

Custom eloquent casting in Laravel 7 is another cool feature. This feature will enable you to add custom casts. Let's take a look at JSON Caster.

<?php
use Illuminate\Contracts\Database\Eloquent\CastsAttributes;
class Json implements CastsAttributes
{
    public function get($model, $key, $value, $attributes)
    {
        return json_decode($value, true);
    }
    public function set($model, $key, $value, $attributes)
    {
        return json_encode($value);
    }
}

Now, we can use the custom eloquent cast in the model.

<?php
namespace App;
use App\Casts\Json;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
    protected $casts = [
        &#39;extra&#39; => Json::class,
    ];
}

Fluent String Operations

In Laravel 7, you can use the Illuminate\Support\Str class to do more cool object-oriented things.

$currentVersion = (string) Str::of('  Laravel 6.x ');
return $currentVersion->trim()
        ->replace('6.x', '7.x')
        ->slug();
// laravel-7x

Blade X

Laravel 7 Blade X features enable you to make class-less components.

Generate x-component

@php($user = $user ?? Auth::user())
@php($size = $size ?? 50)
<img
    class="inline-block rounded-full"
    src="{{ $user->gravatarUrl($size) }}"
    width="{{ $size }}"
    height="{{ $size }}"
/>

Blade x Usage

<x-avatar/>
<x-avatar size="40" />
<x-avatar size="100" />

Customize Stubs

Now you can use artisan command in Custom stubs in Laravel 7.x.

php artisan stub:publish

Query Time Conversion

Laravel 7 provides the withCasts method to help you cast values ​​while running a query. Let's give an example.

$users = User::select([
    'users.*',
    'last_posted_at' => Post::selectRaw('MAX(created_at)')->whereColumn('user_id', 'users.id')
])
->withCasts(['last_posted_at' => 'date'])
->get();

Multiple Mail Drivers

Laravel 7 will allow you to set up multiple mail drivers using a single application.

Mail::mailer('noreply')
        ->to($request->user())
        ->send(new PostUpdated($post));

New Artisan Command

A new artisan test command has been added to Laravel 7. The new artisan test command gives you a beautiful UX and useful information about your tests.

php artisan test

Improvements in Laravel 7

● Routing model binding improvements

● 2x faster routing

● Database queue improvements

● Markdown email template improvements

● and more bug fixes and improvements.

Route model binding improvements

Custom Key

By default, route model binding is used with the id field. Now you can customize it.

Route::get('posts/{post:slug}', function (App\Post $post) {
    return $post;
});

Auto-scoping

Laravel 7 will automatically scope queries to retrieve nested models using the method it identifies conventions for identifying relation calls in your program.

use App\Post;
use App\User;
Route::get('api/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
    return $post;
});

2x faster routing

When using route:cache, Laravel 7’s route matching performance is 2x faster than laravel 6

Database Queue Improvements

Laravel 7 has improvements for applications that use MySQL 8 as a database-backed queue.

Markdown email template improvements

The default markdown template for emails has a newer look using the Tailwind CSS palette. Templates can be published and customized as needed.
