Vue 3.0.0 has been released, and Ionic is working on completing its Ionic Vue support, with a beta release currently available. Vue, similar to React and Angular, relies on a component-based architecture, where components are built as Single File Components (SFCs) using the .vue extension. These components integrate templates, scripts, and styles into a single file, allowing developers to use JavaScript or TypeScript and enabling modular functionality through the setup function. Styles can be scoped to prevent conflicts, and Vue's flexibility allows optional use of tools like routing, state management, and a CLI. Developers can customize their setups by either using Vue's built-in tools or rolling out their solutions. For those keen to learn more, the new Vue 3 documentation offers thorough insights into component syntax, architecture, and best practices.
