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 JsonRpcProvider class provides a connection to the JSON-RPC Server and should be used for all read-only operations. The default URLs to connect with the RPC server are:

• local: http://127.0.0.1:6767
• DevNet: https://dev-seed.rooch.network::443
• TestNet: https://test-seed.rooch.network

For local development, you can run cargo run server start to start a local network. Refer to this guide for more information.

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: '',
})

You can also construct your own in custom connections, with the URL for your own network

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

const client = new RoochClient({
  url: 'http://127.0.0.1:6767',
})

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

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',
})

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 = provider.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.

Type Doc

For the latest docs for the main branch, run pnpm doc and open the doc/index.html in your browser.

Testing

To run tests

pnpm test

check compatibility

pnpm gen
pnpm test
