Masahiko Sakakibara, a recognized Ionic Developer Expert, addresses the challenge of optimizing bundle size and performance in Angular when using Ionicons by introducing the ionic-angular-collect-icons package. This tool automates the process of managing icons, which traditionally involves the manual and repetitive task of using addIcons across multiple components. By minimizing bundle size, the package enhances app speed and developer experience. The process involves installing the package, updating npm scripts, and utilizing a CLI that scans templates for ion-icon elements, collects used icons, and generates a file for efficient icon management. This approach balances development convenience with production efficiency by ensuring only necessary icons are loaded, ultimately improving app performance.
