Getting Started

Install the plugin as a development dependency:

npm install --save-dev @rdlabo/eslint-plugin-rules

The package root provides Angular and Ionic rules. Install @angular-eslint/template-parser and @ionic/core when you enable those rules. Framework-independent TypeScript projects can use the /typescript entry point without loading Angular or Ionic.

Requirements

Package Supported version
Node.js 20 or later
ESLint 9 or later
@typescript-eslint/utils 8.33 or later, before 9
@angular-eslint/template-parser 21.x when template rules are used
@ionic/core 8.x when Ionic rules are used

Choose an entry point

  • Use @rdlabo/eslint-plugin-rules for Angular and Ionic applications.
  • Use @rdlabo/eslint-plugin-rules/typescript for backend and other framework-independent TypeScript projects.

The recommended preset is designed for ESLint Flat Config. Add it at the top level so its TypeScript and HTML file selectors remain intact.

Next step

Continue to Configuration to enable the recommended preset or individual rules.
