To enable CORS in a React App with Node.js backend, we use the cors package.
To install it, we run
npm i cors
Then we use it by writing
const express = require("express");
const request = require("request");
const cors = require("cors");
const app = express();
app.use(cors());
app.use("/", (req, res) => {
//...
});
app.listen(80, () => {
console.log("CORS-enabled web server listening on port 80");
});
We add the cors middleware with
app.use(cors());
to enable CORS
