Deployment and Best Practices

In this challenge, you will build a simple Express app and deploy it to Heroku.

Instructions

Your assignment page on Canvas should contain instructions for submitting this project. If you are still unsure, reach out to School Staff.

Build a simple API:

Create a .gitignore file executing npx gitignore node
Create a package.json file executing npm init --y
Add Eslint to the project executing npx eslint --init
Edit the package.json file to add "start" and "server" scripts
Install express, dotenv, cors
Add support for environment variables using an .env file and the dotenv library, providing fallbacks in the code

Flesh out the API:

Method	URL	Description
GET	/api/users	Returns an array users.
POST	/api/register	Creates a user from { username, password } in the `request body`, responds with newly created user.
POST	/api/login	Checks { username, password } in the `request body`, responds with a welcome message.

Deploy your app to Heroku. The link to the deployed API is your submission deliverable

You can make the API return totally hardcoded responses for the requests from clients (no database).
Alternatively you can use an in-memory array to persist users and act as a database, and build database helpers that interact with the users array.
If you persist users in an array database, know that storing passwords in plain text is a very bad practice from a security standpoint.

Research how to avoid storing passwords as is in your array database.
Research how to grant access to GET /api/users only those clients that are registered and logged in.
Create a front-end piece inside the project containing a register/login form and the means to display users.
