Software Design X-Rays »

Are you working on a codebase where cost overruns, death marches, and heroic fights with legacy code monsters are the norm? Identify and prioritize technical debt based on behavioral data from how developers work with code. Discover surprising dependencies between people and code to resolve coordination bottlenecks among teams. Build on behavioral data that you already have: your version-control system. Join the fight for better code!

Reactive Programming with RxJS 5 »

Reactive programming makes asynchronous programming clean, intuitive, and robust. Use RxJS 5 to write complex programs in a simple way. Learn how to manage real-world concurrency and write complex flows of events in your applications with ease. Take advantage of Schedulers to make asynchronous testing easier. The code in this new edition is completely updated for RxJS 5 and ES6.

Recently Released:

• Complex Network Analysis in Python 
• Design It! 
• Liftoff, Second Edition Audiobook 
• Python Testing with pytest

Software Design X-Rays: Fix Technical Debt with Behavioral Code Analysis

Use statistics and data science to uncover both problematic code and the behavioral patterns of the developers who build your software. This combination gives you insights you can't get from the code alone. Use these insights to prioritize refactoring needs, measure their effect, find implicit dependencies between different modules, and automatically create knowledge maps of your system based on actual code contributions.

In a radical, much-needed change from common practice, guide organizational decisions with objective data by measuring how well your development teams align with the software architecture. Discover a comprehensive set of practical analysis techniques based on version-control data, where each point is illustrated with a case study from a real-world codebase. Because the techniques are language neutral, you can apply them to your own code no matter what programming language you use. Guide organizational decisions with objective data by measuring how well your development teams align with the software architecture. Apply research findings from social psychology to software development, ensuring you get the tools you need to coach your organization toward better code.

If you're an experienced programmer, software architect, or technical manager, you'll get a new perspective that will change how you work with code.

Reactive Programming with RxJS 5: Untangle Your Asynchronous JavaScript Code

Create concurrent applications with ease using RxJS 5, a powerful event composition library. Real-world JavaScript applications require you to master asynchronous programming, and chances are that you'll spend more time coordinating asynchronous events than writing actual functionality. This book introduces concepts and tools that will greatly simplify the process of writing asynchronous programs.

Find out about Observables, a unifying data type that simplifies concurrent code and eases the pain of callbacks. Learn how Schedulers change the concept of time itself, making asynchronous testing sane again. Find real-world examples for the browser and Node.js along the way: how about a real-time earthquake visualization in 20 lines of code, or a frantic shoot-'em-up space videogame? You'll also use Cycle.js—a modern, reactive, web framework—to make a new breed of web applications.

By the end of the book, you’ll know how to think in a reactive way, and how to use RxJS 5 to build complex programs and create amazing reactive user interfaces. You'll also understand how to integrate it with your existing projects and use it with the frameworks you already know. All the code in this new edition has been thoroughly revised and updated for RxJS 5, ES6, and Cycle.js Unified.

Now available in beta from pragprog.com/book/smreactjs5.
