@shelby-protocol/sdk

A TypeScript SDK providing core encoding and decoding utilities for both Node.js and browser environments.

Installation

# Installing the shelby sdk
pnpm install @shelby-protocol/sdk @aptos-labs/ts-sdk

Usage

Depending on your runtime environment, import from one of the following entrypoints:

Node.js

import { ShelbyNodeClient } from '@shelby-protocol/sdk/node';

// Your code here...

Browser

import { ShelbyBlob } from '@shelby-protocol/sdk/browser';

// Your code here...

Working with Erasure Coding Providers

The SDK supports two patterns for managing erasure coding providers:

Default Pattern (Recommended for most users)

import { ShelbyClient } from '@shelby-protocol/sdk';

// Provider is created internally on first use
const client = new ShelbyClient(config);

// The client will automatically create and manage the provider
await client.upload({
  blobData: data,
  signer: account,
  blobName: "example.txt",
  expirationMicros: Date.now() * 1000 + 3600_000_000,
});

Shared Provider Pattern (For advanced use cases)

When working with multiple clients (e.g., different networks), you can share a single provider instance:

import { ShelbyClient, ClayErasureCodingProvider } from '@shelby-protocol/sdk';

// Create a single provider instance
const provider = await ClayErasureCodingProvider.create();

// Share it across multiple clients
const mainnetClient = new ShelbyClient(mainnetConfig, provider);
const devnetClient = new ShelbyClient(devnetConfig, provider);
const testnetClient = new ShelbyClient(testnetConfig, provider);

// All clients use the same provider instance
await mainnetClient.upload({ /* ... */ });
await devnetClient.upload({ /* ... */ });

Please import the entrypoint that matches your environment (/node, /browser, or the root) to ensure you get the correct implementation and avoid missing-module errors.
