React 16 Tooling

Overview of this book

React 16 Tooling covers the most important tools, utilities, and libraries that every React developer needs to know — in detail. As React has grown, the amazing toolset around it has also grown, adding features and enhancing the development workflow. Each of these essential tools is presented in a practical manner and in a logical order mirroring the development workflow. These tools will make your development life simpler and happier, enabling you to create better and more performant apps. Adam starts with a hand-picked selection of the best tools for the React 16 ecosystem. For starters, there’s the create-react-app utility that’s officially supported by the React team. Not only does this tool bootstrap your React project for you, it also provides a consistent and stable framework to build upon. The premise is that when you don’t have to think about meta development work, more focus goes into the product itself. Other React tools follow this same approach to automating and improving your development life. Jest makes unit testing quicker. Flow makes catching errors easier. Docker containers make deployment in a stack simpler. Storybook makes developing components straightforward. ESLint makes writing standardized code faster. The React DevTools plugin makes debugging a cinch. React 16 Tooling clears away the barriers so you can focus on developing the good parts. In this book, we’ll look at each of these powerful tools in detail, showing you how to build the perfect React ecosystem to develop your apps within.

Manually triggering actions


The ability to manually trigger actions during development of a Redux application can be helpful. For instance, you might have components ready, but you're unsure of how the user interaction will work or you just need to troubleshoot something that should be working but isn't. You can use Redux DevTools to manually trigger actions by clicking on the button with the keyboard icon, near the bottom of the pane:

This will display a text input where you can enter the action payload. For example, I've navigated to the book detail page for React Native By Example:

Instead of clicking on the Delete button, I only want to see what happens regarding the state of the application, without triggering DOM events or API calls. To do this, I can click on the keyboard button in Redux DevTools, which allows me to manually enter an action and dispatch it. For example, here is how I would dispatch the DELETING_BOOK action:

This results in the action being dispatched and consequently...
