# TODO(ry) Ideally flatc output files should be written into target_gen_dir, but
# its difficult to get this working in a way that parcel can resolve their
# location. (Parcel does not support NODE_PATH.) Therefore this hack: write the
# generated msg_generated.ts outputs into the js/ folder, and we check them into
# the repo. Hopefully this hack can be removed at some point. If msg.fps is
# changed, commit changes to the generated JS file.
