<template>
  <div>    
    <loader v-if="loading"></loader>   
    <slot v-else></slot>
  </div>
</template>

<script>
import loader from './Loader.vue'

export default {
  components: {
    loader  
  },
  data() {
    return {
      loading: false 
    }
  }  
}
</script>

We see single file encapsulation via script + template, components composed together, reactive bindings etc enabling building complexity starting from intuitive foundations.

State Management in Vue

For simple apps, built-in API like ref, reactive etc may suffice for managing state without needing external libraries.

But for non-trivial apps needing shared state across larger component trees, dedicated state management libraries like:

Vuex – Centralized store for state using mutations, actions, getters etc serving as official recommended library.

Pinia – Provides a store API without verbosity tracking state, getters automatically unlike Vuex’s explicit needs.

These integrate smoothly keeping data flow transparent and debuggable. The choice depends on app scale – integrating state libraries avoids cascading prop chains taxing maintainability.
