Vue 3 Frontend Patterns

Modern frontend patterns for Vue 3 with Composition API.

When to Activate

• Building Vue 3 components (Composition API, props, emits)
• Managing state with Pinia
• Writing composables (equivalent to React custom hooks)
• Implementing data fetching patterns
• Optimizing performance (computed, v-memo, defineAsyncComponent)
• Working with forms and validation
• Using provide/inject for cross-component state
