How to Fix Vue Custom Composables

The Problem

In this quick-fix, you will learn creating reusable composable functions. This matters because composables encapsulate reactive logic. In real-world applications, this pattern appears in shared logic across components.

The Wrong Way

// Logic duplicated in multiple components
function useCounter() {
  return { count: ref(0), increment: () => {} };
}

Incorrect implementation

The Right Way

export function useCounter(initial = 0) {
  const count = ref(initial);
  function increment() { count.value++; }
  return { count, increment };
}

Correct implementation with Composition API

Prevention

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