eslint-config-canonical

A comprehensive ESLint shareable config with 1,000+ rules (40% auto-fixable) and custom ESLint plugin. Current stable version: 47.4.2. Released frequently (10+ versions in recent months). Key differentiators: includes auto-detection ruleset that only applies relevant style guides based on project files, supports many frameworks (React, Next.js, TypeScript, GraphQL, Lodash, etc.) and tools (Jest, Vitest, Mocha, AVA). Requires ESLint ^9 and is ESM-only. No CJS support. Custom rules in eslint-plugin-canonical.
