Why the body parser doesn't work?

JavaScript

Tell us what’s happening:
Hello there ,
I’m doing this challenge of shorting URLs in the FCC challenges so I had to use body parser in order to get the url from the input field , I followed the documentation but I didn’t get any result from the req.body

Your code so far

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

// Basic Configuration
const port = process.env.PORT || 3000;

app.use(cors());
app.use(bodyParser.json());

app.use('/public', express.static(`${process.cwd()}/public`));

app.get('/', function(req, res) {
  res.sendFile(process.cwd() + '/views/index.html');
});

// Your first API endpoint
app.get('/api/hello', function(req, res) {
  res.json({ greeting: 'hello API' });
});

// const Schema = mongoose.Schema;
// const ObjectId = Schema.ObjectId;

// const NewURL = new Schema({
//   oldURL: String,
//   sufix: String,
//   newURL: String,
//   date: Date
// });


app.post('/api/shorturl', (req,res)=>{
  let url = req.body

  console.log(req.body);
  console.log(url)

  res.json({"original_url": url})

} )

app.listen(port, function() {
  console.log(`Listening on port ${port}`);
});

The data is comming from a form POST (x-www-form-urlencoded). Use the urlencoded method instead, check the docs. You also want to get the url property on body and not save body to a url variable (so either destructuring the property or dotting on to it).

I tried that solution in VS Code before using Replit but it didn’t work too , it shows a line on bodyParser word

the Url to the file :

And what do you mean by? I couldn’t get you

You also want to get the url property on body and not save body to a url variable (so either destructuring the property or dotting on to it).

If you hover over it you can see it’s just a deprecation warning. You can use the built-in middleware instead (in Express v4.16.0 onwards), but both will work.

Your code works for me. When I post using the form I see the object in the console and the res.json on the page.

I mean you want the url property on body.

const { url } = req.body

or

const url = req.body.url
