DISCUSSION: react-server-build-tools and react-server-bundleNameUtil

[doug-wade]

We had an interesting situation at Redfin where we accidentally introduced a build-time dependency on React via our build-time dependency on react-server. This is solvable by using relative file imports, but its an easy bug to commit -- at build time you require('react-server/core/util/bundleNameUtil'), and at runtime you require('react-server').bundleNameUtil. I'm not sure how or if we want to fix this, but one way might be to add two new packages: react-server-bundleNameUtil (which contains bundleNameUtil) and react-server-build-tools (which contains react-server-bundleNameUtil and the babel options, and more generally any of the tools that are required at build-time). You could then take a devDep on react-server-build-tools and a dependency on react-server, and have them both work as anticipated (and, if we did need a build-time dependency of React, we could bundle a copy of React and not rely on a peerDep).
