Advanced tools
The web3-providers-ipc package is part of the Web3.js library and provides an IPC (Inter-Process Communication) provider for connecting to Ethereum nodes. This allows for communication with an Ethereum node over IPC, which is generally faster and more secure than HTTP or WebSocket connections.
Create an IPC Provider
This feature allows you to create an IPC provider to connect to an Ethereum node using IPC. The path to the IPC file and the net module are required to establish the connection.
const Web3 = require('web3');
const net = require('net');
const web3 = new Web3(new Web3.providers.IpcProvider('/path/to/geth.ipc', net));
Send a Synchronous Request
This feature demonstrates how to send a synchronous request to get the latest block number from the Ethereum node using the IPC provider.
const Web3 = require('web3');
const net = require('net');
const web3 = new Web3(new Web3.providers.IpcProvider('/path/to/geth.ipc', net));
web3.eth.getBlockNumber().then(console.log);
Handle Provider Events
This feature shows how to handle events such as 'connect' and 'error' when using the IPC provider. This is useful for monitoring the connection status and handling errors.
const Web3 = require('web3');
const net = require('net');
const provider = new Web3.providers.IpcProvider('/path/to/geth.ipc', net);
provider.on('connect', () => {
console.log('Connected to IPC provider');
});
provider.on('error', (error) => {
console.error('IPC provider error:', error);
});
The web3-providers-http package provides an HTTP provider for connecting to Ethereum nodes. Unlike IPC, HTTP is more widely supported and easier to set up but may be slower and less secure. It is suitable for scenarios where IPC is not available or practical.
The web3-providers-ws package provides a WebSocket provider for connecting to Ethereum nodes. WebSocket connections offer real-time communication and are more efficient than HTTP for certain use cases. However, they may not be as secure as IPC connections.
The ethers package is a complete and compact library for interacting with the Ethereum blockchain. It provides various providers, including JSON-RPC over HTTP and WebSocket, but does not natively support IPC. It is known for its simplicity and ease of use compared to Web3.js.
This is an IPC provider sub-package for web3.js.
Please read the documentation for more.
npm install web3-providers-ipc
const Web3IpcProvider = require('web3-providers-ipc');
const net = require(net);
const ipc = new Web3IpcProvider('/Users/me/Library/Ethereum/geth.ipc', net);
All the TypeScript typings are placed in the types
