The Big Picture - helixml/helix - JWT

JSON Web Token (JWT) is a popular method for implementing secure and stateless authentication and information exchange between parties. In this documentation, we will explore how to use JWT in the Helix project with the jwt-node package.

Description

jwt-node is a Node.js adaptation of the jwt-js library for creating and verifying JSON Web Tokens. The latest version of jwt-node is 0.2.0, published over 12 years ago. To install it, run npm i jwt in your terminal. There are currently 2 other projects in the npm registry using jwt.

Why Use JWT

JWT is used for securely transmitting information between parties as a JSON object. It is compact, digitally signed, and can be verified and processed by the client and server. JWT is ideal for stateless applications and APIs.

Example

Here’s an example of how to use JWT in your Helix project:

const jwt = require('jwt');

const payload = {
scope: 'client:outgoing?clientName=matt',
iss: 'APP_SID',
expires: Math.round((new Date().getTime() / 1000)) + 3600
};

const token = new jwt.WebToken(JSON.stringify(payload), JSON.stringify({typ: 'JWT', alg: 'HS256'}));
console.log(token.serialize('hmackey'));

In this example, we create a new JWT token with a payload containing the scope, issuer, and expiration time. The token is then serialized and logged to the console.

Installation

To install JWT in your Helix project, run the following command in your terminal:

npm install jwt
