@janiscommerce/jwt v1.0.0

jwt

A helper to verify Janis JWTs

Installation

npm install @janiscommerce/jwt

API

JWT

This is the main exported class. It has only one public method: async verifyToken(token). This method will resolve the decoded token payload, or reject in case of error.

Configuration

By default this package will handle JWKs properly, but you can configure a custom JWKS URI in case you want to test a different environment.

Precedence

1. An options object with a jwksUri property when you instanciate JWT Class.
2. An environment variable named JANISCOMMERCE_JWT_JWKS_URI
3. Defaults to Janis ID Production URI

Usage

const { JWT } = require('@janiscommerce/jwt');

// Default behaviour, decodes with Janis Production JWKS URI
const jwt = new JWT();
const decodedToken = await jwt.verifyToken(token);

// Override default with an env var
process.env.JANISCOMMERCE_JWT_JWKS_URI = 'https://example.com/.well-known/jwks.json';
const envJwt = new JWT();
const envDecodedToken = await envJwt.verifyToken(token);

// Override by passing jwksUri option
const withOptionJwt = new JWT({
	jwksUri: 'https://override.com/.well-known/jwks.json'
});
const withOptionDecodedToken = await withOptionJwt.verifyToken(token);
