Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

DApp development tools


There are some popular blockchain web development tools used being by developers for creating a basic structure of a DApp project. The following sections list a few of these.

 

Truffle

Truffle is an Ethereum DApp end-to-end development tool that provides a development environment for writing, compiling, and deploying test smart contracts and DApps. You can write HTML, CSS, and JavaScript for the frontend; Solidity is for smart contracts, and uses the web3.js API to interact with the UI and smart contract. Truffle Boxes provide helpful boilerplates, which contain helpful modules, solidity contracts and libraries, frontend code, and many other helpful files. The Truffle Boxes help developers to quickly get started with their DApp project.

The Truffle command line uses the following formats:

  • truffle [command] [options]

Here are the frequently used options in command-line tools:

command
