# SPA Shell Mode Example
This example demonstrates the SPA shell mode feature. When `src/client/index.tsx` (or `.ts`) exists, hype automatically serves a minimal HTML shell at `/` - no `src/pages/index.tsx` needed.
## Structure
```
src/
client/
index.tsx <- This triggers SPA shell mode!
server/
index.ts
```
## Run
```sh
bun install
bun dev
```
Visit http://localhost:3000 to see the SPA in action.
## How it works
When hype detects `src/client/index.tsx` or `src/client/index.ts`, it serves this HTML at `/`:
```html
App
```
Your client code mounts to `#app` and takes over from there.
