Vue.js Patterns: Using Vue.js 3 Composition API for Reactive Parent to Child Communication
Read OriginalThis technical article addresses a common Vue.js pattern: enabling a child component to use a parent's prop as initial state while allowing internal mutation, like for a text input. It explains the pitfalls of using refs naively (as they don't update when the prop changes) and demonstrates the correct solution using the watch() or watchEffect() functions to maintain reactivity and achieve proper two-way data binding with the Vue 3 Composition API.
