Exercise #03 - Case match

Write a server that exposes a /case route.
The body of the request is going to be a number (for example 3) which you should return "spelled out" (three) 

    POST /case
    1
    >>> expected "one"

    POST /case
    2
    >>> expected "two"
Only cover numbers from 1 to 3.

It looks like your server isn't up. This page expects your Haskell application to be listineing on http://localhost:7879.
If you're unsure on how to proceed, read more on how to setup your Local dev environment to complete the exercises.

Reference node.js implementation

          
const app = require("express")()
const bodyParser = require("body-parser")

app.use(bodyParser.raw({ type: "*/*" }))

app.post("/case", (req, res) => {
  let result

  switch (req.body.toString()) {
    case "1":
      result = "one"
      break
    case "2":
      result = "two"
      break
    case "3":
      result = "three"
      break
    default:
      result = "What am I, a mathematician?"
  }

  res.send(result)
})

console.log("Starting server...")
app.listen(7879)

Where to get help

Got stuck? Don't worry! Join the discussion on Github (issue #3). It might be that the exercise could be clearer or there's something you really can't wrap your head around. That's totally fine! 🙂

You can also have a look at my solution. No shame in having a peek. 🧐
But do share your thoughts on the exercises, it would be really helpful!
