Install via composer

Run the following command to pull in the latest version:

composer require tymon/jwt-auth

---

Add service provider ( Laravel 5.4 or below )

Add the service provider to the providers array in the config/app.php config file as follows:

'providers' => [

    ...

    Tymon\JWTAuth\Providers\LaravelServiceProvider::class,
]

---

Publish the config

Run the following command to publish the package config file:

php artisan vendor:publish --provider="Tymon\JWTAuth\Providers\LaravelServiceProvider"

You should now have a config/jwt.php file that allows you to configure the basics of this package.

---

Generate secret key

I have included a helper command to generate a key for you:

php artisan jwt:secret

This will update your .env file with something like JWT_SECRET=foobar

It is the key that will be used to sign your tokens. How that happens exactly will depend on the algorithm that you choose to use.
