Modern JavaScript Applications

By: Narayan Prusty

Overview of this book

Over the years, JavaScript has become vital to the development of a wide range of applications with different architectures. But JS moves lightning fast, and it’s easy to fall behind. Modern JavaScript Applications is designed to get you exploring the latest features of JavaScript and how they can be applied to develop high-quality applications with different architectures. Begin by creating a single page application that builds on the innovative MVC approach using AngularJS, then move forward to develop an enterprise-level application with the microservices architecture using Node to build web services. After that, shift your focus to network programming concepts as you build a real-time web application with websockets. Learn to build responsive, declarative UIs with React and Bootstrap, and see how the performance of web applications can be enhanced using Functional Reactive Programming (FRP). Along the way, explore how the power of JavaScript can be increased multi-fold with high performance techniques. By the end of the book, you’ll be a skilled JavaScript developer with a solid knowledge of the latest JavaScript techniques, tools, and architecture to build modern web apps.

ReactDOMServer.renderToStaticMarkup

Earlier in this chapter, we used React on the server side to generate HTML. The HTML generated by React on the server and client side contains data-reactid attributes, which are used by React internally. On the client side, it makes sense to have data-reactid, as it is used during reconciliation and other processes and features.

You must be wondering what the point of adding this attribute on the server side is. Actually, it is added so that if you call ReactDOM.render() on the client side on a node that already has React server-rendered markup, React will preserve it and only reconcile it.

If you don't want data-reactid attributes to be generated on the server side, you can use renderToStaticMarkup instead of renderToString.
