Host Admin Dashboard with SvelteKit: Application Activity History
Summary
Deploy an admin dashboard built with SvelteKit on Ample using the transactional workflows 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. Verified on SvelteKit: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected).
Representative Queries
- Host admin dashboard with SvelteKit: application activity history
- Where can I host Admin dashboard built with SvelteKit?
- I need an application-owned event schema and tested history queries; not native platform audit logs.
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.
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)
- An Ample account token with servers:write, databases:read
Workflow Steps
- Build and start
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
The fixture's module implements transactional workflows: an optimistic version check and an event row written in the same transaction, a stale update rejected, and a history query over the application-owned events (history=2 conflict=rejected). Copy the approach into your schema; keep migrations idempotent and run them with --release-command. - 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.
Command: ample deploy . --name --public - Verify
Fetch the live URL and the pattern self-test route(s) (/p/transactional-workflows) from the example; then run your own checks. On failure readample logs --kind buildthen--kind runtime.
Command: ample logs --kind build
Examples
- SvelteKit pattern fixture
Multi-pattern SvelteKit app whose transactional workflows module was checked live; the module is under tests/deploy-canaries/_pattern-modules.
Source Reference: tests/deploy-canaries/sveltekit-patterns
Success Checks
- App responds on its public URL
Kind: http_get
Path: /
Expect: ample canary sveltekit patterns - Transactional-workflows self-test
Kind: http_get
Path: /p/transactional-workflows
Expect: tx=ok history=2 conflict=rejected
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 domain records, validation rules and concurrency policy) 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.
Cost Estimate
- Currency: USD
- Monthly Amount: 10.0
- Components:
- App server (size: s-1vcpu-1gb): $5.00
- Managed PostgreSQL database (size: s-1vcpu-1gb): $5.00
- 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 transactional-workflows and configuration-secrets. Observed At: 2026-09-20T03:31:44Z - Kind: canary_run
Summary: The same SvelteKit app deployed with a --release-command migration; the marker it created was readable after activation.
