Answer 1

If you are using Express 4.16+ you don't have to import body-parser anymore. You can do it just like this:

app.use(express.urlencoded({extended: true}));
app.use(express.json()) // To parse the incoming requests with JSON payloads

You are welcome!. And to use JSON you can just go with: app.use(express.json()) – Olivette

Answer 2

Don't use body-parser

body parsing has become builtin with express So, simply use

app.use(express.json()) //For JSON requests
app.use(express.urlencoded({extended: true}));

from directly express

You can uninstall body-parser using npm uninstall body-parser

Then you can simply get the POST content from req.body

app.post("/yourpath", (req, res)=>{

    var postData = req.body;

    //Or like this, for string JSON body

    var postData = JSON.parse(req.body);
});

is JSON.parse(req.body) really needed as long as you used app.use(express.json()) ? I tried to use JSON object properties without JSON.parse() and it still works. – Rafaelrafaela

@Rafaelrafaela Yes it works directly as long as the request has a JSON format and you won't need to use JSON.parse(). But for requests that send JSON in a string form, you will have to use JSON.parse() to get a usable JSON object. One example could be a frontend code that uses fetch to send request to server and sends object as string using JSON.stringify() – Endodontics

Answer 3

Same issue occur to my projects also . Now in latest express we don't need to import body-parse, we can just use express as follow.

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

or if you limit size

app.use(express.urlencoded({ limit: "50mb", parameterLimit: 500000000 }));
