@clustersxyz/data-availability v0.0.6

Clusters Data Availability Library

This library provides a set of tools for interacting with the Clusters data availability layer, which utilizes Arweave for decentralized storage. The main class, ClustersDA, offers methods for managing events, manifests, and data uploads.

Installation

npm install @clustersxyz/data-availability

Usage

First, import the ClustersDA class:

import { ClustersDA } from '@clustersxyz/data-availability';

Then, create an instance of the ClustersDA class:

// Full initialization
const clustersDA = new ClustersDA({
  apiKey: 'your-clusters-api-key',
  manifestUploader: manifestUploaderJWK,
  eventUploader: eventUploaderJWK,
  arweaveRpc: { host: 'arweave.net', port: 443, protocol: 'https' },
});

// Minimal initialization
const clustersDA = new ClustersDA({
  manifestUploader: manifestUploaderAddress,
});

API Reference

Constructor

new ClustersDA(options?: {
  apiKey?: string; // Clusters API key
  manifestUploader?: JWKInterface | string; // JWK or address of the manifest uploader
  eventUploader?: JWKInterface; // JWK of the event uploader
  arweaveRpc?: ApiConfig; // Arweave RPC configuration
})

Methods

getEvents(filter?: EventQueryFilter): Promise<EventResponse>

Retrieves events based on the provided filter via the Clusters SDK.

getCurrentManifest(): Promise<ManifestData[]>

Fetches the current manifest from Arweave.

pushToManifest(data: UploadReceipt[], init?: boolean): Promise<UploadReceipt>

Adds data to the manifest or initializes a new manifest.

queryData(startTimestamp?: number, endTimestamp?: number): Promise<Event[]>

Queries data within the specified timestamp range.

getFileIds(ids: string[]): Promise<(Event[] | ManifestData[])[]>

Retrieves file data for the given IDs.

uploadEvents(events: EventResponse | Event[]): Promise<UploadReceipt>

Uploads events to Arweave.

resumeEventUpload(receipt: UploadReceipt): Promise<UploadReceipt>

Resumes an interrupted event upload.

waitForConfirmation(id: string, retries: number = 30, interval: number = 30000): Promise<void>

Waits for confirmation of an Arweave transaction.

Error Handling

All methods throw errors with descriptive messages if something goes wrong. It's recommended to wrap method calls in try-catch blocks for proper error handling.

Examples

Fetching Events

try {
  const events = await clustersDA.getEvents({ limit: 10 });
  console.log(events);
} catch (error) {
  console.error('Error fetching events:', error);
}

Uploading Events

try {
  const events = [
    /* array of Event objects */
  ];
  const receipt = await clustersDA.uploadEvents(events);
  console.log('Upload receipt:', receipt);
} catch (error) {
  console.error('Error uploading events:', error);
}
