Ethereum for Web Developers
Technology is constantly evolving, and blockchain is taking development to new places, as mobile did a decade ago - and Ethereum is the leading platform for creating this new wave of applications. This book reveals everything you need to create a robust decentralized application (more commonly known as DApp). Unlike other books on the topic, this one focuses on the web application layer, and guides you in creating great experiences on top of the Ethereum blockchain. You'll review the challenges and differences involved in developing DApps as opposed to traditional web applications. After a brief introduction to blockchain history and Ethereum in particular, you'll jump directly into building a sample decentralized application, to familiarize yourself with all the moving pieces. This book offers specific chapters on querying and rendering data from the blockchain, reacting to events, interacting with user accounts, sending transactions, managing gas, handling confirmations and reorga ...

Property-Based Testing with PropEr, Erlang, and Elixir
Property-based testing helps you create better, more solid tests with little code. By using the PropEr framework in both Erlang and Elixir, this book teaches you how to automatically generate test cases, test stateful programs, and change how you design your software for more principled and reliable approaches. You will be able to better explore the problem space, validate the assumptions you make when coming up with program behavior, and expose unexpected weaknesses in your design. PropEr will even show you how to reproduce the bugs it found. With this book, you will be writing efficient property-based tests in no time. Most tests only demonstrate that the code behaves how the developer expected it to behave, and therefore carry the same blind spots as their authors when special conditions or edge cases show up. Learn how to see things differently with property tests written in PropEr. Start with the basics of property tests, such as writing stateless properties, and using the d ...

Build Reactive Websites with RxJS
Upgrade your skill set, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about ...
