A composable TypeScript library implementing both OCI Distribution Specification v1.1 and NPM Registry API for building unified container and package registries.

Features

Dual Protocol Support

OCI Distribution Spec v1.1: Full container registry with manifest/blob operations
NPM Registry API: Complete package registry with publish/install/search

Unified Architecture

Composable Design: Core infrastructure with protocol plugins
Shared Storage: Cloud-agnostic S3-compatible backend (@push.rocks/smartbucket)
Unified Authentication: Scope-based permissions across both protocols
Path-based Routing: /oci/* for containers, /npm/* for packages

Authentication & Authorization

NPM UUID tokens for package operations
OCI JWT tokens for container operations
Unified scope system: npm:package:foo:write, oci:repository:bar:push
Pluggable via async callbacks

Comprehensive Feature Set

OCI Features:

✅ Pull operations (manifests, blobs)
✅ Push operations (chunked uploads)
✅ Content discovery (tags, referrers API)
✅ Content management (deletion)

NPM Features:

✅ Package publish/unpublish
✅ Package download (tarballs)
✅ Metadata & search
✅ Dist-tag management
✅ Token management

Installation

npm install @push.rocks/smartregistry
# or
pnpm add @push.rocks/smartregistry

Quick Start

import { SmartRegistry, IRegistryConfig } from '@push.rocks/smartregistry';

const config: IRegistryConfig = {
  storage: {
    accessKey: 'your-s3-key',
    accessSecret: 'your-s3-secret',
    endpoint: 's3.amazonaws.com',
    port: 443,
    useSsl: true,
    region: 'us-east-1',
    bucketName: 'my-registry',
  },
  auth: {
    jwtSecret: 'your-secret-key',
    tokenStore: 'memory',
    npmTokens: { enabled: true },
    ociTokens: {
      enabled: true,
      realm: 'https://auth.example.com/token',
      service: 'my-registry',
    },
  },
  oci: {
    enabled: true,
    basePath: '/oci',
  },
  npm: {
    enabled: true,
    basePath: '/npm',
  },
};

const registry = new SmartRegistry(config);
await registry.init();

// Handle requests
const response = await registry.handleRequest({
  method: 'GET',
  path: '/npm/express',
  headers: {},
  query: {},
});

Usage Examples

OCI Registry (Container Images)

// Pull an image
const response = await registry.handleRequest({
  method: 'GET',
  path: '/oci/v2/library/nginx/manifests/latest',
  headers: {
    'Authorization': 'Bearer <token>',
  },
  query: {},
});

// Push a blob
const uploadInit = await registry.handleRequest({
  method: 'POST',
  path: '/oci/v2/myapp/blobs/uploads/',
  headers: { 'Authorization': 'Bearer <token>' },
  query: {},
});

const uploadId = uploadInit.headers['Docker-Upload-UUID'];

await registry.handleRequest({
  method: 'PUT',
  path: `/oci/v2/myapp/blobs/uploads/${uploadId}`,
  headers: { 'Authorization': 'Bearer <token>' },
  query: { digest: 'sha256:abc123...' },
  body: blobData,
});

NPM Registry (Packages)

// Install a package (get metadata)
const metadata = await registry.handleRequest({
  method: 'GET',
  path: '/npm/express',
  headers: {},
  query: {},
});

// Download tarball
const tarball = await registry.handleRequest({
  method: 'GET',
  path: '/npm/express/-/express-4.18.0.tgz',
  headers: {},
  query: {},
});

// Publish a package
const publishResponse = await registry.handleRequest({
  method: 'PUT',
  path: '/npm/my-package',
  headers: { 'Authorization': 'Bearer <npm-token>' },
  query: {},
  body: {
    name: 'my-package',
    versions: {
      '1.0.0': { /* version metadata */ },
    },
    'dist-tags': { latest: '1.0.0' },
    _attachments: {
      'my-package-1.0.0.tgz': {
        content_type: 'application/octet-stream',
        data: '<base64-tarball>',
        length: 12345,
      },
    },
  },
});

// Search packages
const searchResults = await registry.handleRequest({
  method: 'GET',
  path: '/npm/-/v1/search',
  headers: {},
  query: { text: 'express', size: '20' },
});

Authentication

// NPM Login
const authManager = registry.getAuthManager();

// Authenticate user
const userId = await authManager.authenticate({
  username: 'user',
  password: 'pass',
});

// Create NPM token
const npmToken = await authManager.createNpmToken(userId, false);

// Create OCI token with scopes
const ociToken = await authManager.createOciToken(
  userId,
  ['oci:repository:myapp:push', 'oci:repository:myapp:pull'],
  3600
);

// Validate any token
const token = await authManager.validateToken(npmToken, 'npm');

// Check permissions
const canWrite = await authManager.authorize(
  token,
  'npm:package:my-package',
  'write'
);

  });

  res.status(response.status);
  Object.entries(response.headers).forEach(([key, value]) => {
    res.setHeader(key, value);
  });

  if (response.body) {
    if (Buffer.isBuffer(response.body)) {
