ESLint Configs

npm version

ESLint has grown complicated for projects with variance:

  • JavaScript or TypeScript
  • Node or Browser
  • App or Library
  • Cross-Platform
  • etc

This project aims to simplify both configuring and overriding ESLint configs.

Install

yarn add --dev @nullvoxpopuli/eslint-configs
# or
npm install --save-dev @nullvoxpopuli/eslint-configs
# or 
pnpm add --save-dev @nullvoxpopuli/eslint-configs

And due to how ESLint resolves plugins, you'll need to ensure that all the dependencies of @nullvoxpopuli/eslint-configs are installed in the root node_modules directory.

This is easier with either yarn workspaces or npm. Standalone yarn with non-monorepos nests node_modules which confuses eslint.

Upgrading across major version boundaries

This goes for major bumps of this package, and any plugin within.

You'll want to use eslint-formatter-todo, so that when you encounter new rules, or a plugin changes the defaults, you can mark them as "TODO". This is effectively temporarily turning errors into warnings, but it allows you to incrementally adopt big changes to your lint configs over time.

This is especially useful on large codebases, and when lint rules don't come with auto-fixers.

I'd recommend updating your lint:js script in package.json to:

"scripts": {
  "lint:js": "eslint . --format @lint-todo/eslint-formatter-todo"
}

See the Usage section of eslint-formatter-todo for details.

Usage

Ember

// eslint.config.js  
import { configs } from '@nullvoxpopuli/eslint-configs';

// accommodates: JS, TS, App, Addon, and V2 Addon
export default configs.ember(import.meta.dirname);

overriding

// eslint.config.js  
import { configs } from '@nullvoxpopuli/eslint-configs';

const config = configs.ember(import.meta.dirname);

export default [
    ...config,
    // your modifications here
    // see: https://eslint.org/docs/user-guide/configuring/configuration-files#how-do-overrides-work
];

Cross-Platform

This config is ESM, as ESM is the most widely supported module format across different distributions (browser, node, etc).

// eslint.config.js  
import { configs } from '@nullvoxpopuli/eslint-configs';

export default configs.crossPlatform(import.meta.dirname);

Node

This config looks at your package.json to determine if your project is CommonJS or ES Modules.

// eslint.config.js  
import { configs } from '@nullvoxpopuli/eslint-configs';

export default configs.node(import.meta.dirname);

overriding

// eslint.config.js 
import { configs } from '@nullvoxpopuli/eslint-configs';

const config = configs.node();

export default [
    ...config,
    // your modifications here
    // see: https://eslint.org/docs/user-guide/configuring/configuration-files#how-do-overrides-work
]

Disabling type-aware linting

import { disableTypedLints } from '@nullvoxpopuli/eslint-configs';

export default [
    // ...
    disableTypedLints.forTests,
];
