Read compilerOptions from tsconfig in cwd

[temapavloff]

Hi Luke!

We use tsm with uvu in our new project. I really like how fast our test are with them.

I'm wondering about why tsm doesn't use all the compilerOptions listed in tsconfig.json from the current working directory.

We have "jsx": "react-jsx" option in our tsconfig.json which is not the default and we had to add the following code into tsm.js file to make it work in tests:

const tsConfig = require('./tsconfig.json');

const tsconfigRaw = {
  compilerOptions: tsConfig.compilerOptions,
};

module.exports = {
  common: {
    tsconfigRaw,
  },
};

It works, but it's a bit less convenient then if tsm could automatically read the compiler options from tsconfig.

What do use think about automatically reading tsconfig if it exists in the project?

Thank you!
