How can I set response header on express.js assets

Question

I need to set CORS to be enabled on scripts served by express. How can I set the headers in these returned responses for public/assets?

Answer 1

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')
