@tinkoff/eslint-config

ESlint plugin includes Tinkoff rules for JS and TS codebase. Better to use with framework-oriented packages @tinkoff/eslint-config-react or @tinkoff/eslint-config-angular

Usage

Install from npm

npm i --save-dev @tinkoff/eslint-config

Then, need to include necessary configurations sets to .eslintrc. Wee need to choose base configuration, and any necessary additional configs. Package include eslint@7 and prettier@2 dependencies, so you should remove eslint, prettier, and @tinkoff/eslint-config internal dependencies from your project package.json.

  "extends": ["@tinkoff/eslint-config/app"]
}

For library

  "extends": ["@tinkoff/eslint-config/lib"]
}

}
