A minimalistic Go library for generating, parsing, and verifying HMAC SHA-256 JSON Web Tokens.
sjwt is a Go library for creating, parsing, and verifying JSON Web Tokens using HMAC SHA-256. It solves the need for a lightweight, no-fuss JWT implementation in Go applications, providing essential features like claim setting, signature verification, and validation of expiration times.
Go developers who need to add JWT-based authentication or secure token handling to their applications, especially those preferring a minimalistic and straightforward library.
Developers choose sjwt for its simplicity, ease of integration, and focus on the most common JWT use case (HMAC SHA-256), avoiding the bloat of more complex alternatives.

The library offers intuitive methods like Set, Generate, and Verify, allowing developers to implement JWT with minimal code, as shown in the basic example with just a few lines.
It specializes in the most common JWT signing method, ensuring reliable security for standard use cases without unnecessary complexity, as emphasized in the 'Why?' section of the README.
Provides built-in helpers for standard JWT claims like issuer, subject, and expiration, demonstrated with methods such as SetSubject and SetExpiresAt for easy integration.
Allows marshaling Go structs directly into JWT claims using sjwt.ToClaims, enabling type-safe claim handling, as illustrated in the example with the Info struct.
Only supports HMAC SHA-256, making it unsuitable for applications that require other signing algorithms like RSA or ECDSA, which are common in more complex security scenarios.
Unlike alternatives, sjwt doesn't provide pre-built middleware for popular Go web frameworks, requiring developers to manually implement token verification in their HTTP handlers.
Focuses on basic JWT operations; lacks features such as token refresh mechanisms, JWE encryption, or complex claim validation beyond expiration and not-before dates.
