Look inside

As the sole engineer for PrincipalStack, an online developer-focused publication, your task is to use an authorization server to log in users and enable your internal team to work in both the newly built community-engaging, single-page application (SPA) and the main (legacy) application—under the same identity. When you’re done, you’ll have leveraged tools including browser-provided JavaScript APIs and HTML to modify the SPA so that it can request, store, and use access tokens tied to that single identity to call the API.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

This liveProject is for intermediate JavaScript developers with some experience working with JavaScript in the browser, including basic browser debugging. To begin these liveProjects you’ll need to be familiar with the following:

  • Basic JavaScript (declare variables, use loops and branches, object and array destructuring, debugging, error handling, etc.)
  • Basic Node.js (including npm and Express.js)
  • Basic command line/terminal proficiency
  • Basic and intermediate in-browser development tool use (such as network call tracing (including URL parameters and request headers) and cookie management)
  • Basic HTML
  • Use npm to create a new JS project and manage packages
  • Store and use environment variables in a Node environment


You choose the schedule and decide how much time to invest as you build your project.
