Vue SPA

Vue 3 + Vite + Pinia + UnoCSS for reactive SPAs.

Stack Components

FrameworkVue 3.5

StylingUnoCSS

Why

Composition API, excellent DX, and fast build times. JavaScript is used by 62% of developers per the Stack Overflow 2024 survey, and React holds 40% framework market share (State of JS 2024).

Vite replaced Webpack as the default bundler, cutting dev server startup from 30s to <1s.

When

Use for interactive web apps. Avoid for very large teams preferring React ecosystem.

How

1. npm create vue@latest myapp 2. npm i pinia unocss 3. Compose components 4. npm run build 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

<script setup> const count = ref(0) </script> <template><button @click="count++">{{ count }}</button></template>

Common Problems

  • ⚠Reactivity pitfalls with destructuring — use toRefs
  • ⚠SSR alignment — ensure Pinia stores are SSR-safe
  • ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

  • ✓Use defineModel for two-way binding
  • ✓Leverage shallowRef for large lists
  • ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is Vue SPA and what projects is it for?

Vue 3 + Vite + Pinia + UnoCSS for reactive SPAs. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

Two steps: (1) npm create vue@latest myapp; (2) npm i pinia unocss. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

When should I NOT choose Vue SPA?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Vue SPA shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
