eth-connect

eth-connect is a TypeScript-based web3 library alternative which implements the Generic JSON RPC spec as well.

You can follow the JavaScript API documentation until TypeScript docs are released.

Design goals

• A Typed web3.js alternative
• Have as few convention-invented functions as possible (by following the RPC specs as much as possible)
• Leverage WS and HTTP providers
• Portable (support and work equally in both browser and node)
• Painless eth usage: Using contract factories, well-split event types (block, transaction and contracts plus topics)
• async/await out of the box

Installation

Using NPM:

npm i eth-connect

Importing as a browser module:

<script src="https://unpkg.com/eth-connect@latest/eth-connect.js"></script>

Examples

Below are some simple illustrative examples. You can also find more complete examples are in the integration /tests folder.

Initialize with a provider

import { RequestManager } from 'eth-connect'

// using the injected MetaMask provider
const requestManager = new RequestManager(web3.currentProvider)

const myBalance = await requestManager.eth_getBalance(myAddress)

or

import { RequestManager, HTTPProvider } from 'eth-connect'

const provider = 'my-own-RPC-url'
const providerInstance = new HTTPProvider(provider)
const requestManager = new RequestManager(providerInstance)

const someBalance = await requestManager.eth_getBalance(someAddress)

Initialize a contract

import { RequestManager, ContractFactory } from 'eth-connect'

const abi = require('./some-contract-abi.json')
// using the injected MetaMask provider
const requestManager = new RequestManager(web3.currentProvider)

const factory = new ContractFactory(requestManager, abi)
const instance = await factory.at(address)

console.log('Calling a method', await instance.mint(myAddress))

Get the accounts

import { RequestManager } from 'eth-connect'

const requestManager = new RequestManager(web3.currentProvider)

const accounts = await requestManager.eth_accounts()
