Using methods is fundamental for organizing component logic in Vue applications, providing a clean way to handle events, perform calculations, and execute reusable functions. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented thousands of Vue methods across components for form handling, data manipulation, API calls, and user interactions in enterprise applications. From my expertise, the most effective approach is to define methods in the methods option with proper naming conventions. This method provides clear component organization, automatic this binding, and excellent debugging experience while maintaining code readability and component reusability.
