dev-config

This package provides reusable development configuration files used across the repository: ESLint, Prettier, and a base tsconfig.

ESLint

The ESLint configuration is based on eslint-config-airbnb-extended, which modernizes and replaces parts of eslint-config-airbnb and eslint-config-airbnb-typescript.

All projects extend the root config at eslint.config.mjs. If a project needs a different configuration, add or override rules in that project's eslint.config.mjs (for example, tdutils).

A typical project config that reuses these shared configs looks like this:

import { configs, defineConfig } from '@todesktop/dev-config/eslint';

export default defineConfig(
  configs.base,
  configs.ts,
  configs.prettier,
  configs.react,
  configs.nodeCommonJs,

  {
    rules: {
      'no-console': 'off',
    },
  },
);

Predefined configs from this package are applied first, then any project-specific rules are merged on top.

See eslint/index.js in this package for a list of available configs and short descriptions.

Some configs come in multiple strictness levels. When you choose a strict variant, also include the base config, since it's not inherited.

| Base | Strict | Description | | ------------ | ----------- | ------------------------------------------------------------------- | | base | strict | JavaScript rules | | ts | tsStrict | TypeScript rules | | react | reactStrict | React-specific rules | | prettier | - | Loads Prettier-related rule adjustments | | node | - | Best practices for Node.js | | nodeCommonJs | - | For CommonJS .js/.cjs files (configs, scripts, not source code) | | esm | - | ESM-specific rules | | unicorn | - | Rules from eslint-plugin-unicorn |

Prettier

A shared Prettier configuration is provided and applied from the repository root, so you usually do not need to add a separate Prettier config inside each subpackage.

tsconfig

A shared TypeScript base config is available. To reuse it, extend it from your package's tsconfig.json:

{
  "extends": "@todesktop/dev-config/tsconfig.json",
  "include": ["src/**/*.ts"]
}
