This repository is a Vue.js single-page application that demonstrates the use of the Composition API via the @vue/composition-api plugin in a Vue 2 project. It fetches data from the CNode API to display a list of topics, includes a search bar for filtering, and uses WeUI for styling. The application consists of a few components (Header, Search, Panel) and a simple global store for state management. While the code is functional and correctly implements the Composition API patterns, it suffers from tight coupling to the global store, outdated dependencies, and a lack of error handling or loading states, making it suitable for learning but not for production use without significant improvements.
