My proposal is suitable for this project
- I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).
Description
I expect that these should throw (when validating parser options):
import tseslint from 'typescript-eslint';
export default tseslint.config(
tseslint.configs.strictTypeChecked,
{
languageOptions: {
parserOptions: {
projectService: true,
tsconfigRootDir: 'not/an/absolute/path',
}
}
}
);(or tsconfigRootDir: 42, or tsconfigRootDir: '.').
In other words, I think the following...
...should have (roughly)
assert(
tsestreeOptions.tsconfigRootDir == null ||
(typeof tsestreeOptions.tsconfigRootDir === "string" &&
path.isAbsolute(tsestreeOptions.tsconfigRootDir)),
);
