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.

primitive:postgres
primitive:s3-compatible-object-storage

Infrastructure Requirements

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.
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.
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

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.
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.
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.
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=...
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.

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).
