We will continue on the path of exploring ExpressJS functionality including working with middleware packages in our Express Application.
Authentication is the process or action of verifying the identity of a user or process. Up to this point you have not been able to create an app utilizing this key concept.
The most common and easiest way to use authentication middleware for Node.js is PassportJS. It is easy to learn, light-weight, and extremely flexible allowing for many strategies, which we will talk about in later challenges. We will also explore template engines, specifically PugJS, and web sockets, Socket.io. Web sockets allow for real time communication between all your clients and your server. Working on these challenges will involve writing your code on Repl.it using our starter project. After completing each challenge you can copy your public Repl.it url (the homepage of your Repl.it app) into the challenge screen to test it! Optionally, you may choose to write your project on another platform but it must be publicly visible for our testing.
Start this project on Repl.it using this link or clone this repository on GitHub! If you use Repl.it, remember to save the link to your project somewhere safe.
After cloning, open the file in your favourite text editor, and run these commands:
- Install dependencies
npm ci- Start development server
npm run dev
