Blue Billywig SAPI Node.js SDK

This Node.js SDK provides abstractions to interact with the Blue Billywig Server API.

Requirements

• Node.js >= 18
• Zero runtime dependencies

Installation

npm install @bluebillywig/bb-sapi-node-sdk

Quick Start

import { Sdk } from '@bluebillywig/bb-sapi-node-sdk';

const sdk = Sdk.withRPCTokenAuthentication(
  'my-publication',
  1,              // token ID
  'shared-secret' // shared secret
);

// List media clips
const response = await sdk.mediaclip.list();
const data = response.json();
console.log(data);

Authentication

The SDK uses HOTP-based RPC token authentication. You need a token ID and shared secret from your Blue Billywig publication settings.

// Recommended: use the convenience factory
const sdk = Sdk.withRPCTokenAuthentication('my-publication', tokenId, sharedSecret);

// Or provide a custom authenticator
import { Sdk, RPCTokenAuthenticator } from '@bluebillywig/bb-sapi-node-sdk';

const authenticator = new RPCTokenAuthenticator(tokenId, sharedSecret);
const sdk = new Sdk('my-publication', authenticator);

Clock synchronization: The RPC token is time-based (HOTP). Both client and server clocks must be reasonably synchronized (within the token expiration window, default 120 seconds). Significant clock drift will cause authentication failures.

Entities

All entities support standard CRUD operations where applicable:

| Entity | List | Get | Create | Update | Delete | |---|---|---|---|---|---| | sdk.mediaclip | Yes | Yes | Yes | Yes | Yes | | sdk.playlist | Yes | Yes | Yes | Yes | Yes | | sdk.channel | Yes | Yes | Yes | Yes | Yes | | sdk.playout | Yes | Yes | Yes | Yes | Yes | | sdk.subtitle | Yes | Yes | Yes | Yes | Yes | | sdk.thumbnail | - | - | - | - | - |

Media Clips

// List
const response = await sdk.mediaclip.list(15, 0, 'createddate desc');

// Get (with optional language and job inclusion)
const response = await sdk.mediaclip.get(123);
const response = await sdk.mediaclip.get(123, 'en', false);

// Create
const response = await sdk.mediaclip.create({ title: 'My Video' });

// Update
const response = await sdk.mediaclip.update(123, { title: 'Updated Title' });

// Delete (with optional purge)
const response = await sdk.mediaclip.delete(123);
const response = await sdk.mediaclip.delete(123, true); // purge

Playlists, Channels, Playouts, Subtitles

// All follow the same pattern
const response = await sdk.playlist.list();
const response = await sdk.playlist.get(1);
const response = await sdk.playlist.create({ title: 'My Playlist' });
const response = await sdk.playlist.update(1, { title: 'Updated' });
const response = await sdk.playlist.delete(1);

File Uploads

The SDK supports single-chunk and multi-part streaming uploads to S3 via presigned URLs.

// 1. Initialize the upload
const initResponse = await sdk.mediaclip.initializeUpload('/path/to/video.mp4');
initResponse.assertOk();
const uploadData = initResponse.json();

// 2. Execute the upload (streams file data, no full-file buffering)
const success = await sdk.mediaclip.executeUpload('/path/to/video.mp4', uploadData);

// 3. (Optional) Track upload progress
for await (const progress of sdk.mediaclip.uploadProgressGenerator(
  uploadData.listPartsUrl,
  uploadData.headObjectUrl,
  uploadData.chunks,
)) {
  console.log(`Upload progress: ${progress}%`);
}

Thumbnails

// Generate an absolute thumbnail URL with dimensions
const url = sdk.thumbnail.getAbsoluteImagePath('/path/to/image.jpg', 640, 360);
// => https://my-publication.bbvms.com/image/640/360/path/to/image.jpg

Response Handling

All entity methods return a SapiResponse object:

const response = await sdk.mediaclip.get(123);

// Check status
if (response.ok) {
  const data = response.json();
}

// Or assert (throws on non-2xx)
response.assertOk();
const data = response.json();

// Access response details
response.statusCode;           // e.g. 200
response.body;                 // raw body string
response.header('Content-Type');
response.queryParam('limit');  // query param from the request URL
response.statusCategory;       // HTTPStatusCodeCategory enum

// Batch response utilities
SapiResponse.allOk(responses);         // true if all 2xx
SapiResponse.assertAllOk(responses);   // throws on first non-2xx
SapiResponse.failedResponses(responses); // generator yielding non-2xx responses

Error Handling

The SDK throws typed exceptions for HTTP errors:

import {
  HTTPRequestException,
  HTTPClientErrorException,
  HTTPServerErrorException,
} from '@bluebillywig/bb-sapi-node-sdk';

try {
  const response = await sdk.mediaclip.get(999);
  response.assertOk();
} catch (error) {
  if (error instanceof HTTPClientErrorException) {
    // 4xx error
    console.error(`Client error ${error.statusCode}: ${error.message}`);
    console.error('Response body:', error.responseBody);
  } else if (error instanceof HTTPServerErrorException) {
    // 5xx error
    console.error(`Server error ${error.statusCode}: ${error.message}`);
  }
}

Configuration

const sdk = Sdk.withRPCTokenAuthentication('my-publication', tokenId, sharedSecret, {
  // Override the base URI (useful for testing or custom deployments)
  baseUri: 'https://custom-host.example.com',

  // Inject a custom fetch implementation (useful for testing)
  fetch: customFetchFn,
});
