Summary JavaScript Application Design: A Build First Approach introduces JavaScript developers to techniques that will improve the quality of their software as well as their web development workflow. You'll begin by learning how to establish build processes that are appropriate for JavaScript-driven development. Then, you'll walk through best practices for productive day-to-day development, like running tasks when your code changes, deploying applications with a single command, and monitoring the state of your application once it's in production. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the Book The fate of most applications is often sealed before a single line of code has been written. How is that possible? Simply, bad design assures bad results. Good design and effective processes are the foundation on which maintainable applications are built, scaled, and improved. For JavaScript developers, this means discovering the tooling, modern libraries, and architectural patterns that enable those improvements. JavaScript Application Design: A Build First Approach introduces techniques to improve software quality and development workflow. You'll begin by learning how to establish processes designed to optimize the quality of your work. You'll execute tasks whenever your code changes, run tests on every commit, and deploy in an automated fashion. Then you'll focus on designing modular components and composing them together to build robust applications. This book assumes readers understand the basics of JavaScript. What's Inside Automated development, testing, and deployment processes JavaScript fundamentals and modularity best practices Modular, maintainable, and well-tested applications Master asynchronous flows, embrace MVC, and design a REST API About the Author Nicolas Bevacqua is a freelance developer with a focus on modular JavaScript, build processes, and sharp design. He maintains a blog at ponyfoo.com. Table of Contents PART 1 BUILD PROCESSES Introduction to Build First Composing build tasks and flows Mastering environments and the development workflow Release, deployment, and monitoring PART 2 MANAGING COMPLEXITY Embracing modularity and dependency management Understanding asynchronous flow control methods in JavaScript Leveraging the Model-View-Controller Testing JavaScript components REST API design and layered service architectures

Create successful test suites for frontend and backend JavaScript apps using the industry's best tools About This Video Follow industry best practices when building test suites for your full-stack JavaScript applications Efficiently test your backend APIs, avoid common mistakes, and maximize test coverage Perform platform-agnostic frontend, backend, and end-to-end testing In Detail JavaScript brings vast amounts of freedom to both frontend and backend developers. However, that freedom comes at a cost: the need to continually screen your applications for bugs and possible optimizations. The presence of multiple testing frameworks such as Jasmine and Mocha confuses newcomers and experienced JavaScript devs when it comes to deciding which one is the best tool for the job. In this course, you will delve into different aspects and specifics of JavaScript testing. You will enhance your skills by mastering many topics that have been a source of confusion in the past-such as integration testing, E2E testing, and Behavioral Driven Development. You will learn how to break down your code into systems that you can challenge individually in an isolated environment, thus catching bugs early before they reach production. With the testing skills you've acquired, you will examine the most available testing frameworks and tools (including Jasmine, Mocha, Chai, and Jest) to find the one that suits you best. Having the right tool for the job will help you work with Test-Driven and Behavioral-Driven Development on all application layers.
