Don't use body-parser

Getting request body is now builtin with express So, you can simply use

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

directly from 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 just like this, for string JSON body

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

If you are using this code

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

then you can replace this code with

app.use(express.urlencoded());

and if you are using

app.use(bodyParser.json());

then replace with

app.use(express.json());

From 4.16.0+ body-parser is inbuilt in express

Use http://expressjs.com/en/api.html#express.json

app.use(express.json({ limit: '50mb' }));
app.use(express.urlencoded())

https://expressjs.com/en/changelog/4x.html#4.16.0

The express.json() and express.urlencoded() middleware have been added to provide request body parsing support out-of-the-box. This uses the expressjs/body-parser module module underneath, so apps that are currently requiring the module separately can switch to the built-in parsers.

https://github.com/expressjs/body-parser/commit/b7420f8dc5c8b17a277c9e50d72bbaf3086a3900

This deprecates the generic bodyParser() middleware export that parses both json and urlencoded. The "all" middleware is very confusing, because it makes it sound like it parses all bodyes, though it does not do multipart, which is a common body type. Also, the arguments for the two different middleware are starting to overlap and it's hard to configure then when done this way.
