Request and Response Objects

'use strict';
// EXAMPLE 1: Use logging to explore request object // ================================================

const express = require('express');
const bodyParser = require('body-parser');

const app = express();

// our app will use bodyParser to try to parse JSON and/or URL encoded data from request bodies. If you don't add body parsing middleware, even if the raw request contains, say, a JSON body, req.body will be empty in the request handler

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));

// we'll run all requests to /example-1 through this function

const logRequest = (req, res, next) => {
  const logObj = {
    time: (new Date()).toTimeString(),
    method: req.method,
    hostname: req.hostname,
    path: req.path,
    "content type": req.get('Content-Type'),
    query: JSON.stringify(req.query),
    body: JSON.stringify(req.body)
  }
  console.dir(logObj);

// we'll learn more about middleware later in this course, but for now know that calling next() causes the next function in the middleware stack to be called

  next();
};

// app.all captures all requests to /, regardless of the request method. app.all('/', logRequest); // GET requests to the root of the server app.get('/', (req, res) => res.send('a okay')); // POST requests to the root of the server app.post('/', (req, res) => res.status(201).send('a okay'));

// listen for requests

app.listen(process.env.PORT || 8080, () => console.log(
  Your app is listening on port ${process.env.PORT || 8080}));
