Installation

yarn add @livepeer/sdk

Usage

Here's a code snippet showing instantiation and basic usage of the Livepeer SDK.

import LivepeerSDK from '@livepeer/sdk'

// Or if you prefer require
// const { LivepeerSDK } = require('@livepeer/sdk')
//
// First, call the SDK factory function
// pass it any configuration options
LivepeerSDK({ ... }).then(async (sdk) => {

  // Once initialized, you can access the methods under the `rpc` namespace
  const { rpc } = sdk

  // For example, you can get the total supply of Livepeer Tokens like so
  const tokens = await rpc.getTokenTotalSupply()

  console.log(tokens)
  // => string representation of some absurdly high number, maybe "9999999999999999999999" or something like that :)
})

To use with a testnet please instantiate with the following params:

const provider = "https://rinkeby.infura.io" #or your testnet of choice
const controllerAddress = "0x37dC71366Ec655093b9930bc816E16e6b587F968"

LivepeerSDK({ provider, controllerAddress }).then(async sdk => {
  mycode...
})

module~exports

Livepeer SDK main module exports

default

Livepeer SDK factory function. Creates an instance of the Livepeer SDK -- an object with useful methods for interacting with Livepeer protocol smart contracts

Parameters

• opts LivepeerSDKOptions SDK configuration options

Examples

// Here we're naming the default export "LivepeerSDK"
