@droneey/devkit-ts-eslint-biome

Lean ESLint configuration for Biome projects. Contains only TypeScript type-checked rules that Biome cannot implement.

Installation

bun add -d @droneey/devkit-ts-eslint-biome eslint typescript-eslint

Create eslint.config.ts in your project root:

import * as devkit from '@droneey/devkit-ts-eslint-biome';

export default [
  ...devkit.configs.base(), // Loads .gitignore automatically
  ...devkit.configs.node(),
  ...devkit.configs.test(),
];

Configuration

Each config is a factory function that returns an ESLint flat config array.

Base

Type-checked rules requiring project: true:

• no-floating-promises -- catches unhandled async calls.
• no-unnecessary-condition -- catches dead code via type analysis.
• switch-exhaustiveness-check -- catches missing switch cases.
• no-unsafe-type-assertion -- catches unsafe as casts.
• naming-convention -- enforces camelCase/PascalCase with type-aware selectors.
• consistent-type-exports -- enforces type-only exports.

Environments

| Config | Description | |---|---| | configs.node() | Node.js globals | | configs.browser() | Browser globals |

Frameworks

| Config | Description | Peer Dependencies | |---|---|---| | configs.nestjs() | NestJS DI patterns, relaxed naming | -- | | configs.react() | Disables naming-convention for JSX | -- | | configs.reactNative() | React Native plugin rules | eslint-plugin-react-native |

export default [
  ...devkit.configs.base(),
  ...devkit.configs.node(),
  ...devkit.configs.nestjs(),
  ...devkit.configs.test(),
];

Test

Relaxes strict rules for test files (*.spec.ts, *.test.ts, *.spec.tsx, *.test.tsx):

• Disables naming-convention, explicit-module-boundary-types, no-explicit-any, no-unsafe-*.
• Allows flexible typing for mocks and fixtures.
