Vue3 Task Management System

Next, we will create a Vue3 Task Management System to consolidate the knowledge points we learned earlier.

• Core Features: Task board, category filtering, data persistence, dark mode toggle, responsive design.
• Tech Stack：Vue 3 (Script Setup) + Vite + Pinia + Vue Router + Element Plus + Tailwind CSS。

Knowledge points included in the task management system:

Phase 1: Project Architecture and Environment Preparation

• Vite Deep Configuration: Configure path aliases@, auto-import pluginsunplugin-auto-import。
• Project Standardization: Integrate ESLint + Prettier + Husky, establish team development standards.
• Styling Solution: Introduce Tailwind CSS to implement atomic CSS development, improving UI development efficiency.

Phase 2: Deep Practice with the Composition API

• Reactive Principle Application: Comparerefandreactivepractical scenarios of (when to use which one?).
• Computed Properties and Watchers: Usecomputedto implement real-time filtering of the task list, usewatchEffectto handle async/sync.
• Lifecycle Hooks: Initialize data inonMounted, clean up timers or event listeners inonUnmounted.

Phase 3: Advanced Component Development

• Component Communication: MasterdefineProps、defineEmitsanddefineExpose。
• Dependency Injection: Useprovideandinjectto solve the problem of passing props through deeply nested components.
• Slots: Use named slots and scoped slots to build highly reusable "modal" and "list item" components.
• Async Components: UsedefineAsyncComponentto implement route lazy loading and performance optimization.

Phase 4: State Management and Routing System

• Pinia in Practice：
• BuildUserStoreandTaskStore。
• implement a persistence plugin (save tasks to LocalStorage).
• UnderstandStore To Refs's destructuring trap.

• Vue Router Advanced：
• Dynamic route configuration and permission guards (Login Guard).
• Route Meta Fieldsmetaapplications (title switching, breadcrumb navigation).

Phase 5: Logic Reuse and Performance Optimization

• Custom Composables: Extract common logic (such asuseLocalStorage、useNotification), achieving true code reuse.
• Performance Tuning：
• UnderstandshallowRefandmarkRawhandling large data volume rendering.
• Usev-onceandv-memodirective to optimize long lists.

Phase 6: Project Deployment and Engineering Implementation

• Environment Variable Management: Distinguish.env.developmentand.env.production。
• Build Optimization: Chunk splitting strategy (Manual Chunks) and Gzip compression configuration.
• Automated Deployment: Implement simple continuous integration via GitHub Actions or Docker.
