The shoemaker's children always go barefoot - where are types?

[OnkelTem]

So a tool for TypeScript generation doesn't provide types for itself.
And hence the parser build script can't be written in TypeScript, the only island of chaos in my kingdom of order.

const parser = peggy.generate("start = ('a' / 'b')+", {
  output: 'source',
  format: 'commonjs',
  plugins: [tspegjs],
  tspegjs: {
     customHeader: '// LALAL',
  },
});

The tspegjs cannot be there according to peggy-s type definitions.

If you see the history of this plugging will notice it was created as a plugging on top of pegjs (a JS parser).
This plugging added some basic typing on top of JS code (not a full TS parser).
Sorry to disappoint your expectations, so far @OnkelTem
