Have you implemented a .eslintrc.js configuration file?
If not, consider adding one to help Webstorm better understand your code:
module.exports = {
parser: '@typescript-eslint/parser',
parserOptions: {
project: 'tsconfig.json',
sourceType: 'module',
},
plugins: ['@typescript-eslint/eslint-plugin'],
extends: [
'plugin:@typescript-eslint/recommended',
'prettier/@typescript-eslint',
'plugin:prettier/recommended',
],
env: {
node: true,
jest: true,
},
ignorePatterns: ['.eslintrc.js'],
rules: {
'@typescript-eslint/interface-name-prefix': 'off',
'@typescript-eslint/explicit-function-return-type': 'off',
'@typescript-eslint/explicit-module-boundary-types': 'off',
'@typescript-eslint/no-explicit-any': 'off',
},
};
Ensure that TypeScript is also enabled in your preferences (refer to the image).
