eslint-config-acme

4.0.0 verified Sat Apr 25 auth: no javascript

Shareable ESLint + Prettier config for React projects. Current stable version is 4.0.0, requiring ESLint 9+ and using the new flat config format (legacy format dropped). It bundles a curated set of plugins including React, JSX a11y, import sorting, and TypeScript support via typescript-eslint. Differentiators include integrated Prettier with sorting plugins, minimal configuration overhead, and both base (JS) and typescript config exports. Release cadence is irregular; major versions introduce breaking changes (ESLint version bumps).

Common errors

error Error: Could not find config 'eslint-config-acme/base' ↓

cause Version 4 uses subpath exports; older versions don't have 'base' export.

fix

Update to v4.0.0+ and use the new import path.

error Cannot find module 'eslint-plugin-import' ↓

cause eslint-plugin-import was replaced by eslint-plugin-import-x in v4.

fix

Install eslint-plugin-import-x and remove eslint-plugin-import.

error Parsing error: The keyword 'const' is reserved ↓

cause ESLint config file is not using ES modules or is not properly configured.

fix

Use .mjs extension or set 'type': 'module' in package.json.
