src-eslint-config

Shared ESLint config for SRC Innovations JavaScript projects.

v2.x requires Node 20+ and ESLint 9+. For Node 16/18 and ESLint 7/8, use v1.x.

Install (v2)

One install brings in ESLint 9 and the stylistic plugin:

npm install -D @srcinnovations/eslint-config

Or install ESLint yourself and use the config only:

npm install -D eslint @srcinnovations/eslint-config

Install (v1 — Node 16/18, ESLint 7/8)

npm install -D @srcinnovations/eslint-config@1

Config

• ECMAScript 2024 (optional chaining, nullish coalescing, etc.)
• Rules: base, es6, style, stylistic (via @stylistic/eslint-plugin)

Future rules may cover: node, errors, imports, strict, variables, React, React a11y, React hooks.

The initial rules were heavily borrowed from the Airbnb JavaScript styleguide.

Flat config (recommended for ESLint 9)

Create eslint.config.js in your project root:

const { FlatCompat } = require('@eslint/eslintrc');
const js = require('@eslint/js');
const compat = new FlatCompat({
  baseDirectory: __dirname,
  recommendedConfig: js.configs.recommended,
});
module.exports = compat.extends('@srcinnovations/eslint-config');

Use __dirname for CommonJS. For ESM ("type": "module"), use import.meta.dirname (Node 20+) or path.dirname(fileURLToPath(import.meta.url)). Install @eslint/eslintrc and @eslint/js as dev dependencies if needed.

Using with .eslintrc (legacy)

ESLint 9 defaults to flat config. If you keep using .eslintrc / .eslintrc.json, run ESLint with legacy config enabled, e.g. in your lint script:

"scripts": {
  "lint": "ESLINT_USE_FLAT_CONFIG=false eslint ."
}
