Laravel JWT - SQL

Laravel is a popular PHP web application framework. It has built-in support for authentication and authorization using sessions, cookies, or tokens. JSON Web Tokens (JWT) are a popular way of implementing token-based authentication in web applications. Laravel has a package called tymon/jwt-auth that provides an easy interface for implementing JWT authentication.

What is SQL?

SQL stands for Structured Query Language. It is a language used to manage relational databases. SQL is used to create, modify and query databases, and it is the standard language for relational databases. SQL provides powerful tools for analyzing, querying, and manipulating data.

Laravel JWT and SQL

When using Laravel JWT, you can store the JWT tokens in a database. SQL can be used to manage the JWT tokens in the database. This is useful because it allows you to store and manage the tokens in a scalable and efficient way.

Here's an example of using Laravel JWT with SQL:

1. Install the tymon/jwt-auth package:

composer require tymon/jwt-auth

2. Generate the JWT secret:

php artisan jwt:secret

3. Create a database table to store the JWT tokens:

Schema::create('jwt_tokens', function (Blueprint $table) {
    $table->id();
    $table->string('token')->unique();
    $table->dateTime('expires_at');
    $table->timestamps();
});

4. Configure the tymon/jwt-auth package to use SQL:

// config/jwt.php
return [
    // ...
    'storage' => 'database',
    'database_table' => 'jwt_tokens',
];

5. Use JWT authentication in your Laravel application:

$token = auth()->attempt($credentials);

This will create a JWT token and store it in the jwt_tokens database table. You can then use SQL to manage the tokens—for example, deleting expired tokens:

DB::table('jwt_tokens')->where('expires_at', '<', now())->delete();

Conclusion

Laravel JWT is a powerful package for implementing token-based authentication in web applications. By using SQL to manage the JWT tokens in the database, you can create a scalable and efficient authentication system for your Laravel application.
