React App - createProxyMiddleware is not a function
Removing the brackets works for me
const createProxyMiddleware = require('http-proxy-middleware');Found that fix here https://www.reddit.com/r/reactjs/comments/jzoo3y/createproxymiddleware_is_not_a_function_how_can_i/
If all React js component files are in the component folder(or in another folder) then shift your Setupproxy.js file in that folder now you can use
const { createProxyMiddleware } = require('http-proxy-middleware');For global, put your Setupproxy.js file in src folder then you have to remove {}
const createProxyMiddleware = require('http-proxy-middleware');
