What headers need to be sent in order for the put and delete methods to work?

Question

Node.js

Good afternoon! I wanted to write a simple MERN application, but the problem is that for the http - put, delete methods, you need to know cors. I can not understand what headers should be sent from the client and server side. The only thing I understood is that it is necessary to send headers from both the client and the server side.
Here is an example how I did it for get, post:

app.use(function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    next();
});

Answer 1

Use cors or
Access -Control-Allow-Origin: * Access-Control-Allow-Methods: POST, PUT, DELETE, OPTIONS
