Book description

Develop, test, and deploy decentralized applications for Ethereum platform

About This Book
  • Build your first Ethereum Dapp with Truffle: the most popular Ethereum development framework
  • Build, compile, and deploy smart contracts in your development environment
  • Embrace Blockchains and utilize it to create new generation of secured and scalable apps
Who This Book Is For

This book is for web developers who are interested in the new world blockchain. Some basic understanding of JavaScript and web services is required. No prior knowledge of Decentralized applications or blockchain is required.

What You Will Learn
  • Understand the fundamentals of Truffle and Web3
  • Build a decentralized application with Truffle, while choosing the correct Ethereum client
  • Connect your Dapp to Ethereum clients including Geth, Parity, and Ganache
  • Migrate and test your Dapp with the correct networks such as Ropsten and Rinkeby
  • Package a decentralized application into a user-friendly product by integrating Truffle with JavaScript frameworks such as Angular, React and Vue
  • Explore tools including Ethereum Package Manager, the Registrar and browser wallets, and exploit third-party smart contract libraries.
  • Evaluate the common migration pitfalls and how to mitigate them
In Detail

Truffle is a world-class development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier.

If you are a web developer wanting to try your hand at developing Dapps with Truffle, then this is the book for you. This book will teach you to write smart contracts and build Dapps with Truffle. You will begin with covering the basics of Truffle, briefly explaining how it integrates Solidity and Web3, in orderto start building a mini decentralized application. Also, you will dive into migration, testing and integrating Truffle with the use of popular JavaScript frameworks. Lastly, you will ship your decentralized application and package it into a product. Moreover, you will go through the best practices in Truffle,so as to increase your proficiency in building Dapps with Truffle.

By the end of the book, you will be able to write smart contracts and build decentralized applications with Truffle on Ethereum blockchains.

Style and approach

An intuitive, step-by-step and engaging guide that will teach you to build a real-world, decentralized application with Truffle.
