Authentication Project

Topics

• Authentication.
• Express Middleware.
• Password Hashing.

Assignment

Part one, due Monday: Use Node.js, Express and Knex to build an API that provides Register and Login functionality using SQLite to store User information. Make sure the password is not stored as plain text.

Part two, due Tuesday: Use sessions and cookies to keep a record of logged in users across requests.

Instructions

You will build the solution from scratch, no starter code is provided. Feel free to structure your API anyway you want, but aim at making it easy to maintain in the future.

Download Project Files

• Fork and Clone this repository.
• CD into the folder where you cloned the repository.
• Do your magic!

Implement Requirements

• Take the steps necessary to create a package.json to keep a record of all dependencies.
• Configure an npm script named "start" that will execute your code using nodemon so that the server restarts on changes. Make nodemon be a development time dependency only, it shouldn't be deployed to production.
• Design and build a set of endpoints listed below.
• Use Postman to test the API as you work through the exercises.

Endpoints

Method	Endpoint	Description
POST	/api/register	Creates a user using the information sent inside the body of the request. Hash the password before saving the user to the database.
POST	/api/login	Use the credentials sent inside the body to authenticate the user. On successful login, create a new session for the user and send back a 'Logged in' message and a cookie that contains the user id. If login fails, respond with the correct status code and the message: 'You shall not pass!'
GET	/api/users	If the user is logged in, respond with an array of all the users contained in the database. If the user is not logged in repond with the correct status code and the message: 'You shall not pass!'. Use this endpoint to verify that the password is hashed before it is saved.

Stretch Problem

• Write a piece of global middleware that ensures a user is logged in when accessing any route prefixed by /api/restricted/. For instance, /api/restricted/something, /api/restricted/other, and /api/restricted/a should all be protected by the middleware; only logged in users should be able to access these routes.
• Build a React application that implements components to register, login and view a list of users. Gotta keep sharpening your React skills.
