Create an http server that can add and subtract from a number, which we will call the "state". Please see in index.js in this folder as starting material. Pay extra attention to line 21, which contains some hints for this week console.log('New http request received', request.url);
Rule 1: DO NOT USE EXPRESS.JS Rule 2: you can use other packages, but you HAVE to also make a version WITHOUT any NPM packages (http, of course, is not NPM but a node native package)
// The state
var state = 10; Endpoints criteria
// /state
// response: the current state in a html format
// when the server starts, this should return "10"
http://localhost:8080/state
// /add
// Response: "ok" in html format
// This should add 1 to the current state
http://localhost:8080/add
// /remove
// Response: "ok" in html format
// This should subtract 1 ƒrom the current state
http://localhost:8080/remove
// /reset
// Response: "ok" in html format
// This should set the state back to 10
http://localhost:8080/reset
// Any other URL
// Response: return error code 404: Not found with a friendly message
// and do not change the state variable

While not strictly homework, we’ve created another playlist if you’d like to learn more or review (and as JavaScript developers, you should). https://www.lynda.com/SharedPlaylist/78e6513f51bb4102b03349460491b4e3
