How do I enable CORS on my server?

To enable CORS, you need to set the appropriate headers in your server's response. What server technology are you using?

I'm using Node.js with Express.

Great! You can use the cors middleware. First, install it using npm install cors, then add it to your app like this: app.use(cors());.

Do I need to configure it for specific domains?

Yes, you can specify allowed origins by passing an options object to cors(). For example: app.use(cors({ origin: 'https://example.com' }));.

What if I want to allow multiple domains?

You can use a function to dynamically set the origin based on the request. Would you like an example?
