Vue 3 has matured into a powerful frontend framework, driven by the modularity of the Composition API. Compared to the older Options API, the Composition API makes code sharing and readability significantly easier.
1. The Power of script setup
By using <script setup>, developers write cleaner, less verbose code. Variables, functions, and imports are automatically exposed to the template, reducing boilerplates by up to 40%.
2. Creating Custom Composables
Custom composables (like useFetch or useAuth) enable developers to package reactive business logic into clean functions, which can be reused across multiple components easily.
3. Migrating to Pinia
Pinia is now the official state management store for Vue 3, replacing Vuex. Pinia eliminates complex mutation blocks, supports type-safety out of the box, and uses a simplified API mapping state, getters, and actions.
