eth-jsonrpc-client

Build Status codecov NPM version

Lightweight HTTP and WebSocket JSON RPC client for Ethereum, compatible with both geth and parity, made for polling blocks for the Ethercast project. Great for when Web3 is too heavy, and the only functionality required is to query the JSON RPC.

Installation

npm install --save @ethercast/eth-jsonrpc-client

Usage

To construct a client, call getClient(nodeUrl: string, validated: boolean) which will construct the appropriate client based on the URL (HTTP client or WebSocket client)

Once you have a client, use one of the supported methods on the interface or call an unsupported method using .cmd, e.g.:

import { getClient } from '@ethercast/eth-jsonrpc-client';

async function printBlockNumber(): Promise<void> {
  const validatedClient = getClient('http://infura.node.io/my-api-key', true);
  const blockNumber = await validatedClient.eth_blockNumber();
  console.log(`blockNumber is ${blockNumber}`);
}
