Installing and configuring web3.js

Web3.js is a JavaScript library that implements the JSON RPC specification of Ethereum. This library allows you to interact with a local or remote Ethereum node, using an HTTP or IPC connection. The following recipe will guide you through installing and configuring web3.js, as well as provide examples to use in your Decentralized Application (DApp).

Getting ready

Since the library is written in JavaScript and distributed via npm, you will need Node.js installed on your machine to use the library. Bower and Meteor versions are also available and you need to have the respective tools to download them.

There are two web3.js releases in use: 0.2x.x, which is the current stable version, and 1.x.x, which is an upcoming release that is currently in beta. We will learn to install and configure both of these versions.

How to do it...

Here are the steps to install web3.js and then configure it:

Install web3 using the npm install command:

npm install web3
