I had same issue, installed manually deprecated package of http2 to bypass that error with npm install http2. I hope they add that module soon in create-react-app

create-react-app seems to hardcode a list of Node built-in modules for which it creates empty mocks: https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/config/webpack.config.dev.js#L451-L457

My guess is that this problem manifested because they haven’t added http2 to the list yet.

It seems like the module isn’t supported on the client side: https://www.npmjs.com/package/firebase-admin#supported-environments

If firebase-admin is not a necessary dependency of the app, then the correct solution is to omit it from the app, not to force it compile when you know that it won’t function.

I guess that one way forward for browser support for google-gax is grpc-web?
