Hi, can you provide more context for this change?

[vtv6]

I'm integrating with Module Federation v2. Every time the shell app requests the mf-manifest.json file, an OPTIONS request is made to check CORS. However, the OPTIONS request always returns a 404 error, causing the CORS check to fail. Therefore, I referred to webpack-dev-server to create this MR

Thanks for the explanation, I have found the related PR from webpack-dev-server: webpack/webpack-dev-server#4559

I will merge this PR and make some changes:

• Check-pick the commit to main branch, because we have no plan to release 0.x version for new features at present.
• Change the status code from 200 to 204, because server does not response any data.
• Move the middleware to the last as a fallback.
