@objectstack/service-package

Runtime package publishing, retrieval, and lifecycle management for ObjectStack — the storage layer behind the dynamic marketplace.

Overview

service-package persists ObjectStack packages — the unit of metadata distribution consisting of a manifest plus its objects, views, apps, flows, agents, tools, and translations — into the sys_packages system table so they can be published, listed, and delivered to runtime kernels that load them through @objectstack/service-marketplace.

Typical consumers:

• Marketplace servers that host first-party and third-party packages.
• Self-hosted platforms that want an internal registry for tenants' custom metadata.
• CI pipelines that publish package artifacts from a Git repository.

Installation

pnpm add @objectstack/service-package

Quick Start

import { ObjectKernel } from '@objectstack/core';
import { PackageServicePlugin, type PackageService } from '@objectstack/service-package';

const kernel = new ObjectKernel();

// Register after a driver/ObjectQL plugin so `ctx.getService('objectql')` resolves.
kernel.use(new PackageServicePlugin());

await kernel.bootstrap();

const packages = kernel.getService<PackageService>('package')!;

await packages.publish({
  manifest: {
    id: 'crm',
    version: '1.2.0',
    name: 'CRM Package',
    /* …full ObjectStackManifest… */
  },
  metadata: {
    objects: [/* … */],
    views:   [/* … */],
    apps:    [/* … */],
  },
});

const latest = await packages.get('crm'); // defaults to 'latest'
const all    = await packages.list();
await packages.delete('crm', '1.0.0');

Key Exports

| Export | Kind | Description | |:---|:---|:---| | PackageServicePlugin | class (default) | Kernel plugin that installs the service and ensures the sys_packages table exists. | | PackageService | interface | Service contract registered under 'package': publish, get, list, delete. | | PackageRecord | type | Stored row shape: id, version, manifest, metadata, hash, created_at, updated_at. | | PackageMetadata | type | Artifact container for objects, views, apps, flows, agents, tools, translations. |

Behavior

• Upsert by (id, version) — re-publishing the same version overwrites manifest, metadata, hash, and updated_at.
• Integrity hash — SHA-256 of { manifest, metadata } is computed on publish and stored alongside the row.
• get(id, 'latest') resolves to the most recently inserted version. Use an explicit version string for pinned lookups.
• list() returns the latest version per package, ordered by created_at DESC.
• System bypass — the service uses IDataEngine.execute() directly (raw SQL), so security/RLS middleware is not applied to registry storage; callers are responsible for authorizing publish/delete at their API layer.

Storage Schema

service-package creates (idempotently) the following table on start():

CREATE TABLE IF NOT EXISTS sys_packages (
  id         TEXT NOT NULL,
  version    TEXT NOT NULL,
  manifest   TEXT NOT NULL,
  metadata   TEXT NOT NULL,
  hash       TEXT NOT NULL,
  created_at TEXT DEFAULT CURRENT_TIMESTAMP,
  updated_at TEXT DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (id, version)
);

CREATE INDEX IF NOT EXISTS idx_packages_latest
  ON sys_packages(id, created_at DESC);

Requirements

• A driver plugin that registers an IDataEngine under the service name 'objectql' with execute() support — typically @objectstack/driver-sql or @objectstack/driver-turso. @objectstack/driver-memory can be used for tests but does not persist across restarts.

When to use

• ✅ Building a marketplace backend or internal package registry.
• ✅ Distributing metadata-only packages to many runtime instances.
• ✅ Versioned audit trail of schema/UI/flow changes.

When not to use

• ❌ Not a package manager for npm/TypeScript source packages — use npm.
• ❌ Not a runtime plugin loader — pair with @objectstack/service-marketplace or a custom loader for that.

Related Packages

• @objectstack/core — kernel hosting this plugin.
• @objectstack/spec — provides ObjectStackManifest and IDataEngine contracts.
• @objectstack/driver-sql, @objectstack/driver-turso — supply the 'objectql' service.
