Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

jwt-auth-utility

jwt-auth-utility is a lightweight and easy-to-use utility package for handling JSON Web Tokens (JWT) in Node.js applications. It simplifies the process of generating, signing, verifying, and refreshing access and refresh tokens, making it ideal for implementing JWT-based authentication in your project.

Features

  • Access & Refresh Tokens: Easily generate and manage access and refresh tokens.
  • Custom Token Lifespan: Configure expiration times for access and refresh tokens.
  • Token Verification: Verify the authenticity of access and refresh tokens.
  • Token Decoding: Decode JWTs without verification for quick access to payload data.
  • Refresh Tokens: Generate new access tokens using refresh tokens.

Table of Contents

Installation

Install the package via npm:

npm i jwt-auth-utility

Usage

Basic Setup

To start using jwtauthutil, first import and initialize the JWT utility by providing your secrets:

import JWT from 'jwt-auth-utility';

const jwtUtil = new JWT('your_access_secret', 'your_refresh_secret', 
  {
    accessTokenLife: '1d',  // Optional, defaults to '1d'
    refreshTokenLife: '7d'  // Optional, defaults to '7d'
  });

Generating Tokens

You can generate both access and refresh tokens by passing a payload:

const payload= 
  {
    userId: 123,
    email: "[email protected]",
    role: "admin"
  } 
const { accessToken, refreshToken } = jwtUtil.generateTokens(payload);

Verifying Tokens

To verify an access token:

const decodedAccessToken = jwtUtil.verifyAccessToken(accessToken);

To verify a refresh token:

const decodedRefreshToken = jwtUtil.verifyRefreshToken(refreshToken);

Refreshing Access Tokens

To generate a new access token using a refresh token:

const newAccessToken = jwtUtil.refreshAccessToken(refreshToken);

Decoding Tokens

You can decode tokens without verifying their validity:

const payload = jwtUtil.decodeToken(accessToken);
