Generating Angular directives enables you to create reusable DOM manipulation logic and custom behavior that can be applied across your application. As the creator of CoreUI, a widely used open-source UI library, I’ve generated hundreds of Angular directives for tooltip behavior, input validation, and custom styling logic across enterprise applications. From my expertise, the most efficient approach is to use Angular CLI’s generate directive command. This method creates the proper directive structure with dependency injection and testing files while following Angular best practices.

Conditional rendering is essential for creating dynamic Angular applications that respond to user interactions and application state changes. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented ngIf in countless Angular components for showing/hiding content, error messages, and conditional UI elements in enterprise applications. From my expertise, the most effective approach is to use the *ngIf structural directive with boolean expressions. This method provides clean template syntax and efficient DOM manipulation by completely removing elements when the condition is false.

Rendering dynamic lists is fundamental in Angular applications, especially for dashboards, data tables, and any component displaying arrays of data. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented ngFor in countless Angular components including data tables, navigation menus, and dashboard widgets. From my expertise, the most efficient approach is to use the *ngFor structural directive with proper TypeScript typing. This method provides clean template syntax and excellent performance when combined with trackBy functions.
