@livepeer/sdk NPM

Livepeer SDK

An SDK for interacting with Livepeer's smart contracts.

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...
})

The following section details the rpc API's function signatures and typedefs.

API

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"
import LivepeerSDK from "@livepeer/sdk";

// Call the factory function and await its Promise
LivepeerSDK().then((sdk) => {
  // Your Livepeer SDK instance is now ready to use
});

Returns Promise<LivepeerSDK>

livepeer~rpc

"rpc" namespace of a Livepeer SDK instance

Examples

import LivepeerSDK from "@livepeer/sdk";

LivepeerSDK().then(({ rpc }) => {
  // Here, we're destructuring the sdk to expose only its rpc namespace
  // Now, you you are able call rpc.<method-name>()
  // All rpc method yield Promises. Their usage is further explained below.
