Deploying a Vue 3 + Vite SPA on Deployxa
Vue 3 with Vite is the fastest way to build a Vue single-page app, and it is a popular choice for AI-generated apps that prefer Vue over React. Vite's fast dev server and optimized builds make it a great developer experience, and Vue 3's Composition API provides a clean, ergonomic way to build components. Deployxa's zero-config engine handles the Vue 3 + Vite deployment automatically, detecting the framework from your package.json and configuring the build and start commands. Here is how to deploy a Vue 3 + Vite SPA on Deployxa.
The direct answer is that Deployxa auto-detects Vue 3 + Vite from your package.json (which includes vue and vite). It configures the build and start commands: the build command is npm run build (which produces a dist/ directory with static files), and the start command runs a static file server. The AutoRepairService handles missing dependencies, and the localhost rewriter fixes hardcoded URLs. You do not write a Dockerfile.

Why Vue 3 + Vite Is a Great Choice for SPAs
Three reasons explain why Vue 3 + Vite is a great choice for SPAs. First, Vue 3's Composition API is clean and ergonomic, which means the LLM can generate correct code reliably. Second, Vite's build is fast (esbuild for development, Rollup for production), which means the build completes quickly. Third, Vue 3's ecosystem (Pinia for state, Vue Router for routing, Vuetify for UI) is mature and well-documented, which means the LLM can leverage existing solutions.

The Architecture: Vue 3 + Vite + Static File Server
Here is how Deployxa deploys a Vue 3 + Vite SPA.
The Vue container
The ingestion service detects Vue 3 + Vite from your package.json. It configures the build and start commands:
- Build command: npm run build
- Output directory: dist
- Start command: Static file server (e.g., npx serve dist or vite preview)
- Runtime: Node 20
The static file server
For SPAs, Deployxa serves the dist/ directory via a static file server, with SPA fallback (all routes fall back to index.html for client-side routing).
The reverse proxy
Traefik v3 routes traffic from your custom domain to the static file server, with automatic SSL via Let's Encrypt.
Step-by-Step: Deploying a Vue 3 + Vite SPA
Here is the exact workflow for a typical Cursor-generated Vue 3 + Vite app.
Step 1: Create your Vue 3 app
npm create vite@latest my-app -- --template vue-ts
cd my-app
npm install
npm install vue-router@4 piniaStep 2: Set up routing
// src/router/index.ts
import { createRouter, createWebHistory } from 'vue-router';
import Home from '../views/Home.vue';
const router = createRouter({
history: createWebHistory(),
routes: [
{ path: '/', component: Home },
{ path: '/about', component: () => import('../views/About.vue') },
],
});
export default router;Step 3: Set up the app
// src/main.ts
import { createApp } from 'vue';
import { createPinia } from 'pinia';
import App from './App.vue';
import router from './router';
const app = createApp(App);
app.use(createPinia());
app.use(router);
app.mount('#app');Step 4: Push to GitHub
git init
git add .
git commit -m "vue 3 + vite spa"
git remote add origin https://github.com/yourname/my-app.git
git push -u origin mainStep 5: Connect to Deployxa
In the Deployxa dashboard, connect your repository. Deployxa auto-detects Vue 3 + Vite:
[ingest] Detected Node.js project
[ingest] Framework: vite
[ingest] Vue detected
[ingest] Runtime: node 20.x
[ingest] Build command: npm run build
[ingest] Output directory: dist
[ingest] Start command: vite preview --host 0.0.0.0 --port $PORTStep 6: Deploy
Click Deploy. The build runs npm run build, which produces the dist/ directory. The container starts the static file server, and your app is live within 60 to 90 seconds.
Step 7: Add a custom domain
Add a custom domain in the Deployxa dashboard. SSL is provisioned automatically.
Step 8: Verify with deployxa doctor
Run deployxa doctor to verify health. The 14-point readiness engine checks SSL, DNS, environment variables, health endpoints, and container status.
Common Pitfalls and Troubleshooting
The first pitfall is SPA routing. Vue Router's history mode requires a fallback to index.html for all routes, which means the server needs to be configured to serve index.html for non-static routes. Deployxa's static file server handles this automatically, but if you are using a custom server, you need to configure the fallback. The second pitfall is the base configuration. If your app is served from a subdirectory (e.g., yourapp.com/app/), you need to set base: '/app/' in vite.config.ts. The third pitfall is environment variables. Vite uses import.meta.env.VITE_* for client-side environment variables, which are inlined at build time. The fix is to set them in the Deployxa dashboard before triggering the build. The fourth pitfall is the vite preview command. vite preview is for local preview, not for production. For production, use a dedicated static file server (e.g., serve or caddy). Deployxa's zero-config engine handles this automatically. The fifth pitfall is code splitting. Vite does not code-split by default, which means a large app can produce a single large JS file. The fix is to use Vue Router's lazy loading (e.g., component: () => import('...')) for route-level code splitting.
Performance: Vue 3 vs React vs Svelte
Vue 3, React, and Svelte are the three leading frontend frameworks in 2026. Vue 3 produces bundles of 100-200KB (because Vue includes a runtime), which is similar to React. Svelte produces smaller bundles (10-50KB), because Svelte's compiler eliminates the runtime. For apps that need the Vue ecosystem, Vue 3 is the best choice. For apps that need the React ecosystem, React is better. For apps that need maximum performance, Svelte is better. Deployxa supports all three equally. For more on framework comparisons, see our articles on deploying a SvelteKit app and deploying a Next.js 15 app.
Conclusion: Vue 3 + Vite Without the Configuration
Vue 3 with Vite is a great choice for SPAs, and deploying it should be as simple as pushing to Git. Deployxa's zero-config engine makes it so: no Dockerfile, no server configuration, no build management. Stop configuring servers and start shipping.
