How to Fix Vue Async Setup

The Problem

In this quick-fix, you will learn using async setup with Suspense. This matters because async setup allows await in component setup. In real-world applications, this pattern appears in data fetching on component initialization.

The Wrong Way

<script setup>
const data = await fetchData(); // Async setup without error handling
</script>

Incorrect implementation

The Right Way

<script setup>
const { data, error } = await fetchData().catch(e => ({ data: null, error: e }));
if (error) console.error(error);
</script>

Correct implementation with Composition API

Prevention

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