Ways to retrieve POST data in express js

When accessing a website in the browser, I use:

  xmlHttp.open("POST", "/", true); // true for asynchronous

  xmlHttp.send("data");

on the client side browser.

For node js application, I'm using:

app.post("/", function (req, res) {
  console.log("Got a POST request");
  console.log(req);
});

to receive post data. However, no matter what data I send, it doesn't display. It's frustrating that I have to install additional "body parser" package just to view data without parsing it. A post request is supposed to send data to the server... Where did the data go?

Answer №1

I refuse to add an additional "body parser" package just to view the data.... I have no interest in parsing it.

Oh well.

Even if you prefer to handle a simple text body, you still need to utilize body parsing middleware for that purpose.

One of the tasks of this middleware is to capture and store the incoming client data in memory (under req.body) instead of discarding it.

Keep in mind that Express.js automatically includes body parsing middleware as part of its dependencies.

Answer №2

Forget about using a standalone body parser library. Instead, leverage express.json, a conveniently available middleware function in Express. Implementation is as simple as:

app.use(express.json())
