## Host Knowledge Base with React Router: Public-Site Delivery

### Summary
Deploy a knowledge base built with React Router on Ample using the public web service pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, and a published bucket serves public assets from the CDN host. Verified on React Router: a versioned, immutable-cached asset uploaded to a published bucket and served from the CDN URL alongside the app's own public HTTPS URL. Not separately tested: your site content and build; treat the knowledge base-specific behavior as your application code.

### Representative Queries
- Host knowledge base with React Router: public-site delivery  
- Where can I host Knowledge base built with React Router?  
- I need an explicit origin-to-CDN delivery path and a tested public content build.

### Infrastructure Requirements
- **Compute**: Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
- **CDN**: The CDN host serves objects from published buckets. It does not front app compute and is not a cache or key-value store.

### Workflow Steps
1. **Build and Start**  
   `react-router build` then `react-router-serve` on the node-22 template. The server must bind 0.0.0.0 on PORT.
2. **Wire Object Storage**  
   Create the bucket(s), then pass endpoint, region, bucket, and keys as --env values. Use path-style addressing. Keep private data in an unpublished bucket. Publish only the bucket that serves public assets and reference its CDN URL.
3. **Deploy**  
   Run the synchronous deploy once and read the result (exit 0 live, 1 failed, 2 blocked). Re-running with no change is a no-op.
   ```bash
   ample deploy . --name --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=... --env CDN_PUBLIC_URL=...
   ```  
4. **Verify**  
   Fetch the live URL and the pattern self-test route(s) (/p/versioned-static-assets) from the example; then run your own checks. On failure read `ample logs --kind build` then `--kind runtime`.
   ```bash
   ample logs --kind build
   ```

### Cost Estimate
- **Currency**: USD  
- **Monthly Amount**: $5.00  
- **Basis**: Size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty

### Limitations
- Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates, and React Router major versions are not verified.
- The knowledge base itself (your site content and build) is application code and was not separately tested.

### Success Checks
- **App responds on its public URL**: Expect `ample canary react router patterns`  
- **Versioned-static-assets self-test**: Expect a CDN URL whose content is served publicly.

### Examples
- **React Router pattern fixture**: Multi-pattern React Router app whose public web service module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
