can u explain briefly how does this works?
What does express.json and express.urlencoded do in the post req
Hi @aditya010sh_cda2cad8fd454417,
Middleware are those methods which are called while processing the request and sending response in the application. Express provides you with middleware to deal with the data in the body of the request.
express.json() and express.urlencoded() is for post & put requests, because in these requests you are sending data in the form of some json data object to server and you are asking the server to accept or store that data, which is enclosed in the body (i.e. req.body ) of that post or put request.
To go by definition :
express.json() is a method which is inbuilt in express to handle incoming request object as a json object . Returns middleware that only parses json .
whereas, express.urlencoded() is a method that is also inbuilt in express to handle incoming request object as strings or arrays . It returns middleware that only parses urlencoded with the qs module.
