Cross-Origin Request Blocked

[Nahasean94]

Am trying to serve built react code and connect to a nodejs server. I have serve running on port 5000 and node backend on port 8080. I have enabled cors on the node server, and it works fine with the default react server that runs on port 3000 when you create a react app. But when I build the react app and serve the front end code with the serve module, the browser throws the error that 'Cross-Origin Request Blocked:...'. I have tried adding options by running the following commands but it wont work.

1. serve --cors -s build
2. serve -C -s build

Anyone with an idea how to enable cors in this module?

Thank you for the effort you've put into this!

This is now possible by supplying a serve.json file. All thanks to serve-handler, as described in the notes for the new release.

Simply add headers to your config file, as described in the serve-handler documentation.

FYI serve --cors was added back in December 2019

same here, even with the --cors option, I get cors errors. I am serving a flutter app that accesses an api on a different domain
