What are some examples of CORS headers?

CORS headers are used to control access to resources on a web server. Examples include 'Access-Control-Allow-Origin', 'Access-Control-Allow-Methods', and 'Access-Control-Allow-Headers'. Would you like to know more about how to implement them?

Yes, how do I set the 'Access-Control-Allow-Origin' header?

You can set the 'Access-Control-Allow-Origin' header in your server's response. For example, in an Express.js app, you can use: res.set('Access-Control-Allow-Origin', '*'); This allows all domains to access your resources.

What does the '*' mean in that context?

The '*' means that any origin is allowed to access the resource. However, for security reasons, it's better to specify a particular domain if possible.

Are there any risks associated with using CORS?

Yes, allowing all origins can expose your API to security risks, such as data theft or abuse. It's important to restrict access to trusted domains.
