jwt-ts

A canonical, minimal-dependency JWT library in TypeScript.

Features implemented:

• JWS signing and verification (compact serialization)
• Algorithms: HS256/384/512, RS256/384/512, PS256/384/512, ES256/384/512, none
• Base64url encoding helpers
• Claim validation for exp, nbf, iat, iss, aud
• Minimal dependencies (Node’s built-in crypto)

Quick start:

1. Install dev dependencies:

npm install

2. Build:

npm run build

3. Run example:

npm run test

API:

• sign(payload, key, options) -> Promise
• verify(token, key, options) -> Promise
• decode(token, {complete})

Notes:

• For RSA/ECDSA signing/verifying provide keys in PEM format (private key for sign, public key for verify).
• ECDSA handling converts between DER and JOSE signatures to comply with JWT format.
