Open your command line and navigate to your repos directory (if you do not have a repos folder, then you can use mkdir repos to create one)
Use this template repository to start a new project in your repos folder: git clone <repo_name>
cd repo_name to navigate into your new repo directory
Start Visual Studio Code and select 'Open Folder'. Then select repo_name to open the folder in the editor (or just type code . in your terminal inside the repo directory)

Exercise
Objective
Create a server that responds to requests
The server should have at least ‘/echo’, ‘/’, and ‘/about’ endpoints
The server will account for ‘not found’ endpoints
The ‘/echo’ endpoint will use the ReadStream response object to read the request body, and return the request body as the response body to the client
The ‘/’ endpoint will respond as you wish
The ‘/about’ endpoint will return a JSON response with information about yourself
Steps
Start in your app.js file
Import the http module
Using the http module, call the createServer
Pass in a request handler callback function to the createServer method that receives request and response objects as parameters
Add an event listener to the request object that listens for the ‘data’ event to be emitted from the ReadStream
Store the chunks in an array
Add an event listener to the request object that listens for the ‘end’ event to be emitted from the ReadStream
Set a new variable ‘body’ equal to Buffer.concat(array).toString()
Write a conditional statement that assesses the request url, and responds appropriately:
‘/’ - Wildcard. Respond with whatever information you wish
‘/about’ - Respond with an object that has information about yourself
‘/echo’ - Respond with an object that, a minimum, includes the request method, url and body.
