Basic Node and Express - Use body-parser to Parse POST Requests

[LoonyToon]

Could Someone Explain This body-parser Challenge:

Hi! I’m a little confused as to about this body-parser challenge. As I understand, we are supposed to be dealing with POST requests and yet I seem to be able to pass the tests without a POST handler.

My initial solution included a chained method:
app.route(path).get(handler).post(handler
as suggested in the previous challenge:

// Note: In the following exercise you are going to receive data from a POST request, at the same /name route path. If you want, you can use the method app.route(path).get(handler).post(handler). This syntax allows you to chain different verb handlers on the same path route. You can save a bit of typing, and have cleaner code.

However, while the solution passed the tests, I couldn’t seem to get anything out of the final .post(handler) including console.logs So, I presumed that for whatever reason, that post(handler) wasn’t running, and indeed, when I removed it from the chain, the solution still passed the tests.

If some could explain what I’m missing here, I would be most grateful. I hate not understanding!!!

Is it simply because the .use(handler)
deals with all restful verbs?

Thanks in advance.

Your code so far

let express = require("express");
let bodyParser = require("body-parser");
let app = express();

console.log("Hello World");

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

app.route("/name").get(function (req, res) {
  res.json({
    name: `${req.query.first} ${req.query.last}`,
  });
})

// You see, I can comment out this next section of code and it still passes the tests:

  .post(function (req, res) {
    console.log(req.body.first, req.body.last);
    res.json({
      name: `${req.body.first} ${req.body.last}`,
    });
  });

module.exports = app;

I hope you’ve passed this by now, but the answer is that the only requirement for this step is to mount the body-parser middleware.

You don’t need to handle POST or return anything, just mount the middleware in that one line, and that’s it.

Yes the tests passed, it just puzzled me as to why because I thought we were supposed to handle the POST request. Thanks for coming back to me and clearing things up though, its much appreciated.

Could someone please explaing to me too.
This is my code:
let express = require(‘express’);

let app = express();
let bodyParser = require(‘body-parser’)

app.use(function middleware(req, res, next) {
express.static(__dirname + “/public”)
bodyParser.urlencoded({ extended: false });
bodyParser.json(req.body);
next();
})

app.get(‘/name’, (req, res) => {
res.send({
name: ${req.query.first} ${req.query.last}
})
})

app.get(‘/:word/echo’, (req, res) => {
const { word } = req.params;
res.json({
echo: word
});
});

app.get(‘/now’, function(req, res, next) {
req.time += new Date().toString();
next();
}, function(req, res) {
res.send({ time: req.time });
});

app.get(“/”, function(req, res) {
res.sendFile(__dirname + ‘/views/index.html’)
});

// Normal usage
// app.use(express.static(__dirname + “/public”));

// Assets at the /public route
app.use(“/public”, express.static(__dirname + “/public”));

app.get(“/json”, (req, res) => {
let response = “”;
if (process.env.MESSAGE_STYLE === “uppercase”) {
response = “Hello json”.toUpperCase();
} else {
response = “Hello json”;
}
res.json({
message: response
});
});

module.exports = app;
