Rooch TypeScript SDK

This is the Rooch TypeScript SDK built on the Rooch JSON RPC API. It provides utility classes and functions for applications to sign transactions and interact with the Rooch network.

WARNING: Note that we are still iterating on the RPC and SDK API before TestNet, therefore please expect frequent breaking changes in the short-term. We expect the API to stabilize after the upcoming TestNet launch.

Installation

npm i @roochnetwork/rooch-sdk

Connecting to Rooch Network

The SDK supports both HTTP and WebSocket connections. You can choose the appropriate transport based on your needs:

HTTP Connection (Default)

import { RoochClient, getRoochNodeUrl } from '@roochnetwork/rooch-sdk'

// create a client connected to testnet
const client = new RoochClient({
  url: getRoochNodeUrl('testnet'),
})

// get balances
await client.getBalances({
  owner: '',
})

WebSocket Connection

import { RoochClient, RoochWebSocketTransport, getRoochNodeUrl } from '@roochnetwork/rooch-sdk'

// Create WebSocket transport with custom options
const wsTransport = new RoochWebSocketTransport({
  url: getRoochNodeUrl('testnet'),
  reconnectDelay: 1000, // Delay between reconnection attempts (default: 1000ms)
  maxReconnectAttempts: 5, // Maximum number of reconnection attempts (default: 5)
  requestTimeout: 30000, // Request timeout (default: 30000ms)
  connectionReadyTimeout: 5000, // Connection ready timeout (default: 5000ms)
})

// Create client with WebSocket transport
const client = new RoochClient({
  transport: wsTransport,
})

// Use client as normal
await client.getBalances({
  owner: '',
})

// Clean up resources when done
client.destroy()

The WebSocket transport provides additional features:

Automatic reconnection on connection loss
Configurable timeouts and retry attempts
Connection state management
Resource cleanup

You can customize the WebSocket behavior through the following options:

url: WebSocket endpoint URL (required)
reconnectDelay: Delay between reconnection attempts in milliseconds
maxReconnectAttempts: Maximum number of reconnection attempts
requestTimeout: Timeout for individual requests
connectionReadyTimeout: Timeout for waiting for connection to be ready
protocols: WebSocket sub-protocols (optional)

Writing APIs

Session Account

import { RoochClient, Secp256k1Keypair, getRoochNodeUrl } from '@roochnetwork/rooch-sdk'

const client = new RoochClient({
  url: getRoochNodeUrl('testnet'),
})

const kp = Secp256k1Keypair.generate()

const session = await client.createSession({
  sessionArgs: {
    appName: 'your app name',
    appUrl: 'your app url',
    scopes: ['0x3::empty::empty_with_signer'],
  },
  signer: kp,
})

Move Call

import { RoochClient, getRoochNodeUrl, Transaction } from '@roochnetwork/rooch-sdk'

const client = new RoochClient({
  url: getRoochNodeUrl('testnet'),
})

const tx = new Transaction()
tx.callFunction({
  target: '0x3::empty::empty_with_signer',
  maxGas: 100000000, // 1RGas, DEFAULT_GAS 50000000 = 0.5RGas
})

const result = await client.signAndExecuteTransaction({
  transaction: tx,
  signer: session,
})

Reading APIs

Move view

import { RoochClient, getRoochNodeUrl } from '@roochnetwork/rooch-sdk'

const client = new RoochClient({
  url: getRoochNodeUrl('devnet'),
})

const result = await client.executeViewFunction(
  '0x49ee3cf17a017b331ab2b8a4d40ecc9706f328562f9db63cba625a9c106cdf35::counter::view',
)

Building Locally

To get started you need to install pnpm, then run the following command:

# Install all dependencies
$ pnpm install
# Run the build for the TypeScript SDK
$ pnpm build

All pnpm commands are intended to be run in the root of the Rooch repo. You can also run them within the sdk/typescript directory, and remove change pnpm sdk to just pnpm when running commands.
