What is body parsing in Express.js?

Junior NodeJS
Quick Answer HTTP requests from clients arrive with bodies (JSON, form data, raw text). By default, Express doesn't parse them รขโ‚ฌโ€ you must add middleware. express.json() parses JSON bodies; express.urlencoded() parses form data. Without body parsing, req.body is undefined. These are included in Express 4.16+ รขโ‚ฌโ€ no need for the separate body-parser package.

Answer

Body parsing converts request payloads to usable objects. express.json() handles JSON bodies.
