How to Fix Ref vs Reactive

The Problem

In this quick-fix, you will learn deciding when to use ref vs reactive. This matters because choosing the right API avoids issues. In real-world applications, this pattern appears in any reactive state declaration.

The Wrong Way

const items = reactive([]); // Primitive array

Incorrect implementation

The Right Way

const items = ref([1, 2, 3]); // Use ref for primitives and arrays

Correct implementation with Composition API

Prevention

• Always use the official API
• Follow Vue best practices
• Test your implementation
• Document your patterns
