The reason I'm trying to speed up the build is my build time has gone up massively and I'm not sure why. It used to be a few seconds and now it is consistently 1.6 mins.

Latest compile:

Hello @JonCatmull , please install TypeScript npm install typescript -g and try again.

@JonCatmull , still existing issue?

I once had the same suspicious "Failed to parse file..." error after having run tsc (without --project tsconfig.json if I remember correctly). The solution was to delete every .js and .js.map files generated by that tsc, and to always use the npm run build.dev/prod build commands instead of tsc in this seed. But beware, only delete .js files for which there exist corresponding .ts files, i.e. there are still some raw JS-only scripts in this seed.

Somehow the tsconfig.json in this seed interferes with the remaining build process.

Apologies I will test try these 2 commands today and let you know
