How do I enable CORS in my web application?
An example of an AI chatbot conversation about enabling CORS in web applications.
How do I enable CORS in my web application?
To enable CORS, you need to set the appropriate headers in your server's response. Are you using a specific framework?
Yes, I'm using Express.js. What headers do I need to set?
In Express.js, you can use the cors middleware. Just install it and add app.use(cors()) to your app.
What if I want to restrict access to certain domains?
You can pass an options object to the cors middleware, specifying allowed origins like this: app.use(cors({ origin: 'https://example.com' })).
