Laravel JWT

Simple JWT Auth for Laravel PHP Framework using Firebase JWT under the hood.

Installation

Standard Composer package installation:

composer require rcerljenko/laravel-jwt -v

Usage

1. Publish the config file. This will create a config/jwt.php file for basic configuration options.

php artisan vendor:publish --provider="RCerljenko\LaravelJwt\LaravelJwtServiceProvider" --tag="config"

2. Add a new auth guard to your auth config file using a jwt driver.

// config/auth.php

'guards' => [
	'web' => [
		'driver' => 'session',
		'provider' => 'users',
	],

	'api' => [
		'driver' => 'jwt',
		'provider' => 'users',
	],
],

3. Protect your API routes using this new guard.

// routes/api.php

use Illuminate\Support\Facades\Route;

Route::middleware('auth:api')->group(function () {
	// JWT protected routes
});

4. Use provided HasJwt trait from this package on your Auth model (eg. User).

namespace App\Models;

use RCerljenko\LaravelJwt\Traits\HasJwt;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
	use Notifiable, HasJwt;
}

You now have access to token() method on your User model, eg:

$user = User::findOrFail(1);
$user->token();

You should probably return this token via Login Controller or User Resource.

Configuration

This package provides simple configuration via config/jwt.php file after you publish the config. Let's go over each configuration option.

• secret-key - Secret key to use when encoding / decoding tokens. It should be a random string. Remember, if you change this key all active JWT tokens will be invalidated.
• hash-algo - Hashing algorithm. List of supported ones are in the config file. You probably don't need to change this.
• expiration - Default token expiration time in minutes. You can set it to null and the tokens will never expire.
• claims - Default claims that will be applied to all tokens (besides the required ones needed for decoding and validation).

This was global configuration for all tokens. Besides that, library provides a local per-model configuration via HasJwt trait helper methods.

• getJwtId() - It should return the model unique key used to retrieve that model from database. It defaults to model primary key.
• getJwtValidFromTime() - It should return null (default) or a Carbon instance. You can use that if you want to create tokens which are not active right away.
• getJwtValidUntilTime() - It should return null or a Carbon instance. This sets the JWT expiration time which, by default, uses the expiration option from the config file.
• getJwtCustomClaims() - Should return a key/value array of extra custom claims that you want to be a part of your token. By default it's an empty array.

You can also use configuration directly on the token() method which then overrides all other configurations, eg:

$user->token([
	'id' => $user->email,
	'valid_from' => now()->addHour(),
	'valid_until' => now()->addDay(),
	'claims' => [
		'extra1' => 'foo',
		'extra2' => 'bar'
	]
]);

You don't need to override all configuration options, just the ones that you wish to change.

Request

Token is extracted from the request in one of three ways:

1. From Authorization: Bearer {token} header (most common).
2. From URL query param token.
3. From request payload using token field name.
4. From cookie using token key.
