How do I use a proxy server to bypass CORS in React Axios?

To use a proxy server, you'll typically use a library like `http-proxy-middleware`. Here's a basic example: 1. Install the library: `npm install http-proxy-middleware`. 2. Configure it in your `create-react-app` or similar setup. You'll usually do this in `src/setupProxy.js`: ```javascript module.exports = { proxy: { '/api': { target: 'https://api.example.com', changeOrigin: true } } } ``` This tells the proxy to forward requests to `/api` to `https://api.example.com`. The `changeOrigin: true` option modifies the `Origin` header in the forwarded request to reflect your React app's origin. Then, in your Axios request, you'll make the request to your local proxy URL (e.g., `/api/some-endpoint`).
