# Host admin dashboard with SvelteKit: private documents

Deploy an admin dashboard built with SvelteKit on Ample using the private document library pattern. Compute runs the app in an isolated microVM behind a public HTTPS URL, a managed PostgreSQL 16 database is auto-provisioned and injected as DATABASE_URL, a private S3-compatible bucket holds objects with credentials delivered as encrypted environment variables. Verified on SvelteKit: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). Not separately tested: your identity integration and role assignments; treat the admin dashboard-specific behavior as your application code.

## Representative Queries
- Host admin dashboard with SvelteKit: private documents
- Where can I host Admin dashboard built with SvelteKit?
- I need a role-to-document access model and negative authorization tests.

## Resource Requirements
- primitive:compute
- primitive:postgres
- primitive:s3-compatible-object-storage

## Infrastructure Requirements
1. **Compute**  
   - **Status:** verified  
   - **Summary:** Apps run in isolated x86_64 Firecracker microVMs that auto-pause when idle and wake on request; sizes are the priced VM sizes.
2. **Postgres**  
   - **Status:** verified  
   - **Summary:** Managed PostgreSQL 16 runs in its own microVM and is auto-provisioned when an app needs a database and no DATABASE_URL is supplied.
3. **S3-compatible object storage**  
   - **Status:** verified  
   - **Summary:** Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.

## Prerequisites
- A SvelteKit project that builds and starts with the documented commands (vite build with @sveltejs/adapter-node then node build on the node-22 template)
- A PostgreSQL driver reading DATABASE_URL at runtime (auto-provisioned when omitted, or supplied with --env)
- A bucket from `ample bucket create` with its credentials passed as encrypted S3_* environment variables
- An Ample account token with servers:write, databases:read, buckets:read

## Tested Configuration
- **Template:** node-22
- **Runtime:** node
- **Size:** s-1vcpu-1gb
- **Install:** npm install
- **Build:** npm run build --if-present
- **Start:** npm run start

## Workflow Steps
1. **Build and start**  
   - Body: vite build with @sveltejs/adapter-node then node build on the node-22 template. The server must bind 0.0.0.0 on PORT.
2. **Implement the pattern on PostgreSQL**  
   - Body: The fixture's module implements private document library: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok). Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
3. **Wire object storage**  
   - Body: 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.
4. **Deploy**  
   - Body: 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.
   - Command: ample deploy . --name  --public --env S3_ENDPOINT=... --env S3_REGION=... --env S3_BUCKET=... --env S3_ACCESS_KEY_ID=... --env S3_SECRET_ACCESS_KEY=...
5. **Verify**  
   - Body: Fetch the live URL and the pattern self-test route(s) (/p/private-document-library) from the example; then run your own checks. On failure, read `ample logs  --kind build` then `--kind runtime`.
   - Command: ample logs  --kind build

## Success Checks
- app responds on its public URL
  - **Kind:** http_get
  - **Path:** /  
  - **Expect:** ample canary sveltekit patterns
- private-document-library self-test
  - **Kind:** http_get
  - **Path:** /p/private-document-library
  - **Expect:** private=ok (with ?role=owner; 401 without, 403 for viewer)

## Limitations
- Verified on the node-22 template at s-1vcpu-1gb with the example fixture; other sizes, templates and SvelteKit major versions are not verified.
- The admin dashboard itself (your identity integration and role assignments) is application code and was not separately tested; the pattern checks are what was verified.
- Region, compliance attestations and request-duration limits are unknown and not claimed.
- Apps auto-pause when idle and wake on the next request; always-on is an operator setting, not a plan feature.
- Managed PostgreSQL 16 only; extensions, connection limits and backup or restore procedures are not verified; apps and their databases are placed together.
- PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not verified.

## Cost Estimate
- **Currency:** USD
- **Monthly Amount:** 10.0
- **Authoritative:** true
- **Basis:** size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty
- **Components:**
  - **Name:** app server  
     - **Size:** s-1vcpu-1gb  
     - **Quantity:** 1.0  
     - **Monthly Amount:** 5.0  
  - **Name:** managed PostgreSQL database  
     - **Size:** s-1vcpu-1gb  
     - **Quantity:** 1.0  
     - **Monthly Amount:** 5.0
- **Note:** Always-on monthly price of the tested sizes; apps and databases auto-pause when idle. Buckets are allocation-priced per quota and not included.

## Evidence Summary
- **Kind:** canary_run  
   - **Summary:** SvelteKit pattern fixture deployed on Ample (vite build with @sveltejs/adapter-node then node build on the node-22 template); checks passed for private-document-library and configuration-secrets. Pattern proof: a role-to-document access model with negative tests (401 without identity, 403 for the wrong role) and a private-bucket round-trip for the allowed role (private=ok).
