This repository contains a simple web application built with Bun, a web framework in Go, that demonstrates how to implement JWT (JSON Web Tokens) based authentication middleware.

JWT (JSON Web Tokens) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the plaintext of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted.

This repository showcases the implementation of JWT-based authentication middleware in a Bun web application.

• JWT Authentication Middleware: Implementation of JWT-based authentication middleware.
• User Authentication: Demonstrates how to authenticate users using JWT tokens.
• Protected Routes: Certain routes are protected and can only be accessed with a valid JWT token.
• Token Generation: Provides functionality to generate JWT tokens for authenticated users.
• Custom Claims: Ability to add custom claims to JWT tokens.

To use this application:

1. Clone the repository:

   git clone https://github.com/JaphetRugas/jwt-middleware-app-hono.git
   

2. Navigate to the project directory:

   cd jwt-middleware-app-hono
   

3. Install dependencies:

   bun install
   

4. Run the application:

   bun run dev
   

5. Access the application in your web browser at http://localhost:3000.

1. Login:

   • Make a POST request to /login endpoint with user credentials in the request body.
   • Upon successful authentication, the server responds with a JWT token.

2. Access Dashboard:

   • Make requests to protected routes (e.g., /dashboard) with the generated JWT token.
   • Ensure the JWT token is included in the request header with the Authorization field.
   • Set the header prefix as Bearer.
   • The JWT token should be included in the header as follows:
     • Type: JWT Header
     • Algorithm: HS256
     • Secret: [Your Secret Key]
     • Request header prefix: Bearer
     • JWT header: token
