Google AngularJS Style Guide

Official Google AngularJS coding standards for consistent Angular 1.x applications.

Note: This guide covers AngularJS (Angular 1.x). For modern Angular (2+), see the Angular style guide.

Golden Rules

1. One component per file — easier to maintain and test
2. Use controllerAs syntax — avoid $scope when possible
3. Services for business logic — keep controllers thin
4. Explicit dependency injection — array annotation or $inject
5. Modular structure — organize by feature, not type
6. Use directives — for DOM manipulation only
7. Avoid $rootScope — use services for shared state
