[service] skip the typechecker but *do* perform tsconfig lookup? about ts-tools

[cspotcode]

Thanks! And thanks for the quick fix on those other 2 issues.

This module is saving me a ton of time. Often I wish tsc did something slightly different (logging diagnostics as JSON, skipping the typechecker, etc) It's historically been too annoying to re-implement the basic tsc infrastructure to get to a point where I can implement my behavior on top. @ts-tools/service makes it super-easy.

I wanted this for @ts-tools/node as well. Will probably add support for it soon.
Appreciate the feedback!

Here's the workaround I'm using for this, similar to the workaround in #9.

import { TypeScriptService } from '@ts-tools/service';
const service = new TypeScriptService();
// Trigger discovery and parsing of tsconfig
service.transpileFile('DOES NOT EXIST.ts', {
  tsconfigFileName : 'tsconfig.json',
  getCompilerOptions = (baseHost, tsconfigOptions) =>tsconfigOptions
});
const runningService = service.runningServices.get('tsconfig.json')!;
// Get parsed compiler options
const parsedCompilerOptions = runningService.languageService.getProgram()!.getCompilerOptions();
// transpile file *without* typechecking *with* our tsconfig's compiler options
service.transpileFile('foo.ts', {
  isolated: true,
  getCompilerOptions = (baseHost, tsconfigOptions) =>parsedCompilerOptions
});

Happy to hear this package helps others. 👍

I already have some WIP to resolve this issue, but it might have to wait for the weekend, when I have more free time.

apologies for the delay. going to release [email protected] that allows this.
