eslint-config-atomic

ESLint configuration used in atom-ide-community. Supports ESLint 9 flat config.

Lints JavaScript, TypeScript, JSON, HTML, YAML, and Astro files out of the box.

Installation

npm install --save-dev eslint-config-atomic

eslint-config-atomic@^2 -> Eslint 9 and higher eslint-config-atomic@^1 -> Eslint 8 and lower

If using pnpm, either add the following to your .npmrc to hoist bundled dependencies automatically:

public-hoist-pattern[]=*

Or install them explicitly:

pnpm install --save-dev eslint typescript @babel/core

Usage

Create an eslint.config.cjs at the root of your project:

const config = require("eslint-config-atomic")

module.exports = [{ ignores: ["dist/**", "node_modules/**"] }, ...config]

Add a lint script to your package.json:

"lint": "eslint --fix --cache .",
"test.lint": "eslint --cache ."

Variants

All variants are non-strict by default — lint violations are reported as warnings (via eslint-plugin-only-warn). Use the strict-* variants to report them as errors.

| Entry point | Description | | ----------------------------------- | -------------------------------------------------- | | eslint-config-atomic | Base config (JS + TS + JSON + HTML + YAML + Astro) | | eslint-config-atomic/strict | Same as base, but errors instead of warnings | | eslint-config-atomic/react | Base + React (eslint-plugin-react) | | eslint-config-atomic/strict-react | React, strict | | eslint-config-atomic/solid | Base + SolidJS (eslint-plugin-solid) | | eslint-config-atomic/strict-solid | SolidJS, strict |

Example using the React variant:

const config = require("eslint-config-atomic/react")

module.exports = [{ ignores: ["dist/**", "node_modules/**"] }, ...config]
