Index

Chapter 25. Getting Started with web3.js

In this chapter, we will learn web3.js and how to import, connect to geth, and use it in Node.js or client-side JavaScript. We will also learn how to build a web client using web3.js for the smart contract that we created in the previous chapter.

In this chapter, we'll cover the following topics:

Importing web3.js in Node.js and client-side JavaScript
Connecting to geth
Exploring the various things that can be done using web3.js
Discovering various most used APIs of web3.js
Building a Node.js application for an ownership contract
