A guide to JWT authentication in Go

JSON Web Tokens (JWTs) are widely used for online authentication and can be implemented in various server-side programming languages, including Go. This tutorial guides users on how to set up JWT authentication in Go applications using the golang-jwt package, which is well-known for its functionality and ease of use. The process involves setting up a web server, generating JWTs with a secret key, and verifying these tokens using middleware functions. The tutorial emphasizes the importance of using cryptographically secure keys and managing them via environment variables. Additionally, it describes how to extract claims from JWT tokens for authorized requests. The tutorial includes a detailed code walkthrough and highlights best practices for securing RESTful APIs with JWTs, offering resources for further exploration on the LogRocket blog.
