Structuring Large Quasar Projects With Composables

As a Quasar app grows, clarity matters more than cleverness. Composables help you keep logic reusable and testable without turning your app into a maze.

Define Clear Boundaries

• UI components in components/
• Feature logic in composables/
• Route data in pages/

Name Composables by Intent

Good naming saves hours of onboarding:

			export const useBilling = () => {
    const invoices = ref([]);
    const fetchInvoices = async () => {
        invoices.value = await $fetch("/api/billing/invoices");
    };
    return { invoices, fetchInvoices };
};

		

• useBilling
• useProductAccess
• useThemeBuilder

Keep Composables Focused

Each composable should do one thing:

• Fetch data
• Manage state
• Provide helpers

If it does more than one, split it.

Use Modules When Features Grow

Create feature folders when a domain grows:

• composables/billing/
• components/billing/
• pages/billing/

Summary

Composable structure scales Quasar apps cleanly. Keep folders predictable, focus composables by intent, and your team will move faster.
