Making Prettier understend TS "as" operator when it is working with eslint

Question

I'am tring to use Prettier with ESLint for TS. But it's fails with an error

SyntaxError: Unexpected identifier, expected the token `)` (17:55)

On line with

const initialState = !process.env.IS_SERVER ? (window as any).__INITIAL_DATA__ : {};

This errror related with prettier.

I have installed all recomended plugins for ES to work with prettier and TS. ES config here (.eslingrc.js):

module.exports = {
  parser: "@typescript-eslint/parser", // Specifies the ESLint parser
  extends: [
    "plugin:react/recommended", // Uses the recommended rules from @eslint-plugin-react
    "plugin:@typescript-eslint/recommended", // Uses the recommended rules from the @typescript-eslint/eslint-plugin
    "prettier/@typescript-eslint", // Uses eslint-config-prettier to disable ESLint rules from @typescript-eslint/eslint-plugin that would conflict with prettier
    "plugin:prettier/recommended" // Enables eslint-plugin-prettier and eslint-config-prettier. This will display prettier errors as ESLint errors. Make sure this is always the last configuration in the extends array.
  ],
  parserOptions: {
    ecmaVersion: 2018, // Allows for the parsing of modern ECMAScript features
    sourceType: "module", // Allows for the use of imports
    ecmaFeatures: {
      jsx: true // Allows for the parsing of JSX
    }
  },
  rules: {
    // Place to specify ESLint rules. Can be used to overwrite rules specified from the extended configs
    // e.g. "@typescript-eslint/explicit-function-return-type": "off",
  },
  settings: {
    react: {
      version: "detect" // Tells eslint-plugin-react to automatically detect the version of React to use
    }
  }
};

I use IDE WebStorem. Operator extends for types fails with prittier too.

Why it is don't understand "as" operator? Help me, please.

Answer 1

In .eslintrc add parser as "typescript".

rules: {
  "prettier/prettier": ["error", {"singleQuote": true, "parser": "typescript", "endOfLine": "auto"}]
}

This fixed it for me.

Answer 2

If you're using a .prettierrc file then add "parser": "typescript" to the object.

{
  "tabWidth": 2,
  "singleQuote": true,
  "parser": "typescript"    <<----
}

If you're not using a .prettierrc file then @Steve Tomlin's answer should do the trick.

Check, prettier file config extension (.prettierrc.json)
