Chapter Notes

Wire in the Flags#

  • elm-ts-json Decoder is a drop-in replacement for our original elm/json Flags Decoder
  • Run elm-ts-interop in watch mode npx elm-ts-interop --output src/Main.elm.d.ts --watch
  • Using InteropPorts.decodeFlags (the module from running elm-ts-interop init) ensures that our generated types and TypeScript types are in sync
