shared

I can't figure out how to get create-react-app to use shared code in a monorepo Typescript setup like Zinc.

My current bodgey work-around is to put the shared code underneath the CRA project and import it into the lambda code with a relative reference all the way into /client/src/Shared from the lambda package.json (as a "file" dependency: "Shared": "file:../../client/src/Shared").

Things that don't work for me:

• CRA doesn't support NPM/Yarn workspaces or Lerna: https://github.com/facebook/create-react-app/issues?q=is%3Aissue+is%3Aopen+workspaces
• CRA doesn't support Typescript project references
• CRA has an [explicit restriction](https://stackoverflow. com/a/44115058/924597) on importing code from outside its /src directory.
• CRA "mods" like craco or rewire don't yet support CRA v5, and I avoid tools like that anyway - the whole point of using CRA is to avoid build hassles.
• I tried using NPM file: dependencies but it doesn't work well with Typescript, see commit cb7c9f1a for the last version of the code using that approach.
• I don't want to use NPM linking because of needing to re-run the compile/plublish cycle after each change.

Other approaches:

• put the shared code back in a top-level directory and just use a simple build copy command to copy the code out into each project that needs it. Could make a watch style command that you run during dev to constantly copy changes as you make them, relying on running process to pick up changes via hot module reloading for front end.
  • I'm in favor of this because at the end of the day, in a real repo, I'd be doing something like this based on an IDL to share interfaces across different language implementations anyway.
