How to allow CORS in react.js?

Question

I\'m using Reactjs and using API through AJAX in javascript. How can we resolve this issue? Previously I used CORS tools, but now I need to enable CORS.

Answer 1

on the server side in node.js I just added this and it worked. reactjs front end on my local machine can access api backend hosted on azure:

// Enables CORS
const cors = require('cors');
app.use(cors({ origin: true }));
