Before You File a Bug Report Please Confirm You Have Done The Following...

I have tried restarting my IDE and the issue persists.
I have updated to the latest version of the packages.
I have searched for related issues and found none that matched my issue.
I have read the FAQ and my problem is not listed.

Repro

To the root of a project that is using EXPERIMENTAL_useProjectService: true recently I added rollup.config.js. That file was not added to tsconfig's include list. ESLint throws:

Error while loading rule '@typescript-eslint/consistent-type-exports': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

By the way, it was so exciting to see the EXPERIMENTAL_useProjectService option added. The project I talk about is rather experimental so it was perfect playground to tryout the ProjectService.

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  parserOptions: {
    "EXPERIMENTAL_useProjectService": true
  }
};

tsconfig

{
  "include": ["./src"]
}

Expected Result

Perhaps the error could be more useful. If this should be an error at all. Not sure what is going on.

Actual Result

Looking at the error, I thought that maybe the option was removed or stoped working.

Ahh so exciting that you're trying out the new option @mrazauskas! 🙌

Would you be able to provide us with a minimum reproduction of what you're seeing locally? Failing that, would we be able to see the original code? We're happy to sign whatever NDAs are needed if this is private.

Reproduction is here: https://github.com/mrazauskas/x-use-project-service

Install with yarn
Run yarn lint and you will see the error
Delete rollup.config.js file in the root
Run yarn lint and the error is gone
Bring rollup.config.js file back
Open tsconfig.json and uncomment one line in the include list
Run yarn lint, there will be no error as well

I ran into this too today.

Error: Error while loading rule '@typescript-eslint/dot-notation': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

My config (override object):

files: ['*.{ts,tsx}'],
settings: {
  'import/parsers': {
    '@typescript-eslint/parser': ['.ts', '.tsx', '.d.ts'],
  },
  'import/resolver': {
    node: {
      extensions: ['.js', '.jsx', '.json', '.d.ts', '.tsx', '.ts', '.mjs'],
    },
  },
},
parser: '@typescript-eslint/parser',
parserOptions: {
  project: ['./tsconfig.json', './tsconfig.integration.json'],
  EXPERIMENTAL_useProjectService: true,
},
extends: [
  'plugin:@typescript-eslint/eslint-recommended',
  'plugin:@typescript-eslint/recommended',
],
plugins: [
  '@typescript-eslint',
],

The file being linted is included by ./tsconfig.integration.json but it seems like that project settings field might be ignored now?

The only debug information from the plugin is:

  typescript-eslint:typescript-estree:createSourceFile Getting AST without type information in TSX mode for: /Users/esj/code/frontend-v2/packages/cad-pro/src/integration/autodesigner/autodesigner-defaults.docker-integration.tsx +0ms

Then it crashes. FWIW other files seem to be working just fine and the performance is significantly better!

Thanks for the reminder - I was actually able to repro this myself. I did a brief dive and it doesn't look easy to solve.

I'm hoping to close out some work on DefinitelyTyped this month (DefinitelyTyped/DefinitelyTyped#65993), then pick up this issue in earnest after that.

mrazauskas · 2024-04-15T17:35:32Z

@JoshuaKGoldberg It feels like this issue is resolved after #8815. Or?

JoshuaKGoldberg · 2024-04-15T17:41:12Z

Yes, good call - thanks! #8815 also resolved this.

We'll push out more comprehensive docs soon (#7350).
