eslint-config-landr

2.0.0 verified Sat Apr 25 auth: no javascript

LANDR's shareable ESLint configuration for JavaScript and TypeScript projects. Current stable version is 2.0.0, released with peer dependencies eslint >=8 and prettier >=3. Extends eslint-config-prettier and eslint-plugin-prettier to show formatting issues as ESLint errors. Supports framework-specific configs for React and test files. Requires TypeScript parser for JS/TS linting, with typescript as a peer dependency. Includes rules for import ordering with TypeScript path patterns and Lingui i18n.

Warnings

breaking Version 2.0.0 requires eslint >=8 and prettier >=3. Older versions may not work. ↓

fix Update eslint and prettier to compatible versions.

gotcha TypeScript parser is used even for JS files; typescript must be installed as a peer dependency. ↓

fix Install typescript as a devDependency.

gotcha Prettier configuration is expected from a .prettierrc.js file in the project root; if missing, default prettier options are used. ↓

fix Create a .prettierrc.js file or use prettier-config-landr.
