Express and nodeJS: [Object: null prototype] { }

The only one reason why you get something like this: [Object: null prototype] it's because { extended: false };

Now, you try to change your extended to true. For an example, you can look at this code below:

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

I've tried that code above and it's working fine.

Update Express

npm i express

The new version doesn't need body-parser But you can set extended to true

ok, first the request was coming from an app in nagular 8 which had an interceptor with a misconfigured header.

this was my header:

Content-Type': 'application/x-www-form-urlencoded;charset=utf-8

was replaced by this:

```Content-Type': 'application/json`

it is important to know this is the default header in case we do not assign a header.

then in the back, we started to receive an empty object, after that we just used

app.use(bodyParser.json());

and voilà, that was the solution to the problem.

Thank you all for your prompt response.

Let me try a fast ball, would love some more information..

It looks like you might be missing a " after otherPotatoParameter. Right now the key in the object is the object..

{ 
'{"someParameter": "potatoParameterValue", "someOtherParameter": "otherPotatoParameter}': '' 
}

Maybe it should be something like this?

{
  "someParameter": "potatoParameterValue", 
  "someOtherParameter": "otherPotatoParamete"
}

Use

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

or

app.use(express.urlencoded({extended: true}))

its working in my case

const express = require('express');

const app = express();

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

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

// app.use(express.urlencoded({extended: true}))

app.use('/',(req ,res ,next) => {

console.log('In the Another Middleware');
    // res.send('<title>Node Learning</title><h1>Hello From Express JS!</h1>');
    next();
})

app.use('/add-product',(req ,res , next) => {
   console.log('In the Another Middleware');
    res.send('<form method="POST" action="/product"><input type="text" name="title" /> 
 <button type="submin">Add</button></form>');
})
app.use('/product',(req , res , next) => {
   console.log(req.body);
    res.redirect('/');
});

app.use('/',(req ,res , next) => {
    console.log('In the Another Middleware');
    res.send('<title>Node Learning</title><h1>Hello From Express JS!</h1>');
})

app.listen(3000);
