What it is

airbnb/javascript is an ESLint configuration and style guide repository that codifies Airbnb's JavaScript coding standards for modern ES6+ projects. It provides two main npm packages (eslint-config-airbnb for React/JSX projects and eslint-config-airbnb-base for plain JavaScript) that enforce rules around syntax, formatting, and best practices, plus companion guides for React-specific patterns and CSS-in-JavaScript conventions. Monorepo structure: root package.json orchestrates two parallel npm workspaces under packages/ — eslint-config-airbnb-base/ (core rules split across rules/*.js files for best-practices, errors, es6, imports, node, strict, style, variables) and…

Start here

Open these first:

• packages/eslint-config-airbnb-base/index.js — Entry point for the base ESLint configuration shared across all projects; defines core linting rules.
• packages/eslint-config-airbnb/index.js — Entry point for the full ESLint configuration including React rules; extends the base config.
• README.md — Primary style guide documentation covering JavaScript conventions, patterns, and best practices.
• packages/eslint-config-airbnb-base/package.json — Declares dependencies for the base ESLint config including eslint and linting plugins.
• packages/eslint-config-airbnb/package.json — Declares dependencies for the full ESLint config including React and JSX-related plugins.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/airbnb/javascript.git
cd javascript
npm install

The repository uses npm workspaces; npm install at root runs preinstall hooks that automatically install both packages/eslint-config-airbnb and packages/eslint-config-airbnb-base via the install:config and `inst…

Daily commands:

This is not an executable application; instead, run the test suite:

npm test

This executes npm run lint (markdownlint) then npm run test:config && npm run test:config:base (testing each package's ESLint config). For CI, use npm run travis (runs travis:config and travis:config:base).

…shortened for this brief.

Key cautions & unknowns

• Slowing — last commit 5mo ago
• Concentrated ownership — top contributor handles 50% of recent commits
• Scorecard: marked unmaintained (1/10)
• Postinstall hook quirk: rimraf node_modules/markdownlint-cli/node_modules/markdownlint removes markdownlint from markdownlint-cli's node_modules; if your Node version or npm version handles transitive…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
