***POST DRILL***

// import express
const express = require("express");

// init a new express app
const app = express();

//tells app to navigate to the endpoint "echo:/what" why are (req, res) in parentheses? 
//Q: 
app.get("/echo/:what", (req, res) => {
  res.json({
    hostname: req.hostname,
    query: req.query,
    params: req.params
  });
});

//tells app to listen for requests
app.listen(process.env.PORT, () => {
  console.log(`Listening on port ${process.env.PORT}`);
});

//Q: These are undefined but seem to have an inherent function, are they node commands/methods? require, get, req, res, listen, process
//Q: Why are we doing this? What does this do?
//Q: when we click "show live" it says "cannnot GET" is this the intended result or an error 
//Q: logs just say listening, when do they show activity? How is Glitch connected to Postman?


****MAD LIBS DRILL****
"use strict";

// import express
const express = require("express");

// init a new express app
const app = express();
// use express middleware to parse the request body and add it to the request object
app.use(express.json());

function doMadlib(body) {
  // we use destructuring to get the values for adjective1, adjective2, etc.
  // from the request params
  const {
    adjective1,
    adjective2,
    adjective3,
    adverb,
    name,
    noun,
    place
  } = body;
  // then we return a string that substitutes in these values
  return (
    `There's a ${adjective1} new ${name} in ${place} and everyone's ` +
    `talking. Stunningly ${adjective2} and ${adverb} ${adjective3}, all the cool kids know it. ` +
    `However, ${name} has a secret - ${name}'s a vile vampire. \n` +
    `Will it end with a bite, or with a stake through the ${noun}?`
  );
}

// POST requests to the root of the server
// Pass params for doMadlib as JSON in the request body
app.post("/", (req, res) => res.send(doMadlib(req.body)));

// listen for requests :)
app.listen(process.env.PORT, () =>
  console.log(`Your app is listening on port ${process.env.PORT}`)
);

//Q: How do we get the request params? What would that look like? E.g. a form with fields for user input with class names "adjective1", "adjective2", etc that get slipped into the cost above?
//Q: Show live is not working, why? Needs an HTML file right?
