Parsing error: Cannot read file '.../tsconfig.json'.eslint

By default, the projects (in parserOptions) are resolved relative to the current working directory. If you run eslint in a different working directory to the folder containing tsconfig.json, @typescript-eslint/parser will not be able to locate the file.

To fix this, you can set tsconfigRootDir to __dirname, which would make the parser resolve the project configuration relative to .eslintrc.js:

module.exports = {
  // ...
  parserOptions: {
    project: "tsconfig.json",
    tsconfigRootDir: __dirname,
    sourceType: "module",
  // ...

If you’re having some trouble with

  0:0  error  Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: .eslintrc.js.
The file must be included in at least one of the projects provided

see this question.

A VSCode-specific approach, that worked for me was to create a .vscode folder in the root project directory and add the following property to the settings.json file inside it:

  "eslint.workingDirectories": [

The "src" could be any directory, which should be in eslint's scope.
