Summary

By · Reviewed & last updated · Part of Vue Tutorial

Wrapping up the Vue 3 track with what you can ship and where to go next.

What you learned + useFetch composable

EXAMPLE
# Vue 3 summary

You can now:

- Author components with <script setup> + TypeScript
- Use ref, reactive, computed, watch, watchEffect deliberately
- Define props + emits + slots with strict types
- Build forms with VeeValidate + Zod
- Manage state with Pinia
- Route with vue-router v4 including guards
- Use Suspense + async components
- Test with Vitest + Vue Test Utils + Playwright

# Your next step - a useFetch composable

// composables/useFetch.ts
import { ref, onUnmounted } from 'vue';

export function useFetch<T>(url: string) {
  const data    = ref<T | null>(null);
  const error   = ref<unknown>(null);
  const pending = ref(true);
  const ctl = new AbortController();

  fetch(url, { signal: ctl.signal })
    .then((r) => r.ok ? r.json() : Promise.reject(new Error(\`HTTP ${r.status}\`)))
    .then((d) => data.value = d)
    .catch((e) => error.value = e)
    .finally(() => pending.value = false);

  onUnmounted(() => ctl.abort());
  return { data, error, pending };
}

Why it matters

Vue 3 + Composition API + Pinia + Vite is a tight, ergonomic stack. The framework rewards staying inside its conventions. For SSR, reach for Nuxt; for huge org-wide systems, evaluate Vue vs React for hiring rather than capability - both can do it.

Tip: Tweak the snippet with Try it Yourself », then sit the quiz at the bottom of the page.
