Mar 26, 2021 · body-parser is an NPM package that parses incoming request bodies in a middleware before your handlers, available under the req.body property. app.use(bp.json()) looks at requests where the Content-Type: application/json header is present and transforms the text-based JSON input into JS-accessible variables under req.body.

The bodyParser will populate the req.body property with the parsed body from the request. With the Line 1 you will just get one to you use in your class via require. Returns middleware that only parses urlencoded bodies. This parser accepts only UTF-8 encoding of the body and supports automatic inflation of gzip and deflate encodings.
