Watches Elixir sources and regenerates the TypeScript client on change.
Runs rpc.gen.ts once on startup. Then re-runs it when a .ex file under a
watched directory changes. Each run spawns a fresh mix rpc.gen.ts process.
The fresh process is deliberate. An in-process Mix.Task.rerun("compile")
misses source edits. The Elixir compiler caches its manifest for the lifetime
of the BEAM. It reports :noop, and the generated client goes stale. A
separate process re-reads the manifest from disk and recompiles correctly.
Usage
mix rpc.gen.ts.watch --router MyApp.Router --out path/to/rpc.gen.tsAccepts every option rpc.gen.ts accepts, plus --dir: a directory to
watch. Repeatable, defaults to lib.
Requires the optional :file_system dependency:
{:file_system, "~> 1.0", only: :dev}
