Introduction to JWT Authentication in Go Fiber

JSON Web Tokens (JWT) provide a secure and efficient way to handle authentication in modern web applications. This tutorial will guide you through implementing JWT authentication in a Go Fiber v2 application.

Prerequisites

Project Setup

First, let's create a new Go project and install the necessary dependencies:

Creating the Basic Structure

Let's start by creating a basic Go Fiber application structure:

Implementing JWT Middleware

Create a middleware to handle JWT authentication:

Creating Authentication Routes

Implement login and protected routes:

Best Practices and Security Considerations

Testing the Implementation

You can test your JWT implementation using curl or Postman:

Error Handling

Implement proper error handling for various scenarios:

Conclusion

This tutorial covered the basic implementation of JWT authentication in a Go Fiber v2 application. Remember to adapt the code according to your specific needs and security requirements. The implementation can be extended with additional features like refresh tokens, role-based access control, and more sophisticated error handling.
