Why @Body() in Post request is not working properly? [Nest.js]

Question

I\'m starting to learn Nest.js, so I am following an Academind Tutorial (link).

My code is not working as expected when I try to get the body variable w

Answer 1

You're sending form-data which NestJS does not correctly parse by default. You can use application/x-www-url-form-encoded or application/json along with the raw option in Postman. The JSON body would look like so:

{
  "id": "7",
  "title": "Whatever Title",
  "desscription": "whats doc",
  "author": "Me"
}

And then your server will recognize the body properly. The other option would be to add in a body parser that properly parses form-data. There are several options out there like multer, form-parser, formidable, and others.
