Host marketplace with SvelteKit: public product media

Deploy a marketplace built with SvelteKit on Ample using the public media 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, and a published bucket serves public assets from the CDN host. Verified on SvelteKit: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. Not separately tested: your media processing, object layout and cache policy; treat the marketplace-specific behavior as your application code.

Representative Queries

Host marketplace with SvelteKit: public product media
Where can I host Marketplace built with SvelteKit?
I need product-to-object mappings and a tested public media delivery path.

Resource Requirements

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

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.
Postgres: 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: Buckets are S3-compatible with issued credentials; PutObject and GetObject are verified by canary. Other S3 operations are not verified.
CDN: The CDN host serves objects from published buckets; it does not front app compute and is not a cache or key-value store.

Execution Status

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 and a second, published bucket for public assets (CDN_*)
An Ample account token with servers:write, databases:read, buckets: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 public media library: an object written to a published bucket with an immutable Cache-Control header, a mapping row, and the CDN URL serving it publicly. Copy the approach into your schema; keep migrations idempotent and run them with --release-command.
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.

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.

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=...

Verify: Fetch the live URL and the pattern self-test route(s) (/p/public-media-library) from the example; then run your own checks. On failure read ample logs --kind build then --kind runtime.
```
ample logs --kind build
```

Examples

SvelteKit pattern fixture: Multi-pattern SvelteKit app whose public media library module was checked live; the module is under tests/deploy-canaries/_pattern-modules. Source: tests/deploy-canaries/sveltekit-patterns

Success Checks

app responds on its public URL (HTTP GET path: /) expecting: ample canary sveltekit patterns
public-media-library self-test (HTTP GET path: /p/public-media-library) expecting: a CDN URL whose content is served publicly

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 marketplace itself (your media processing, object layout and cache 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.
PutObject and GetObject with path-style addressing are verified; multipart upload, listing, presigned URLs and lifecycle rules are not.
The CDN serves published-bucket objects only; cache rules, purge and TTL control are not verified (the fixture sets Cache-Control on upload and versions keys).

Cost Estimate

Monthly Amount: $10.00 USD (authoritative)
Basis: Size prices from pricing.toml (loaded by the API) at build revision 1ac5595375130d45290090e82ed0f554ccd45405-dirty

Components

App server: s-1vcpu-1gb, quantity: 1.0, monthly amount: $5.00
Managed PostgreSQL database: s-1vcpu-1gb, quantity: 1.0, monthly amount: $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.
