@rdlabo/eslint-plugin-rules

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, @ionic/angular, 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 or 22.x
@ionic/angular	9.x when Ionic rules are used
@ionic/core	9.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.

For Ionic templates, the preset also requires ion-item elements inside ion-list to use ion-item-group, ion-reorder-group, ion-radio-group, or ion-accordion within ion-accordion-group, matching the iOS 26 and Material Design 3 list structure.

Next step

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