Overview of this book

Awarded as one of the best books of all time by BookAuthority, Cloud Native Programming with Golang will take you on a journey into the world of microservices and cloud computing with the help of Go. Cloud computing and microservices are two very important concepts in modern software architecture. They represent key skills that ambitious software engineers need to acquire in order to design and build software applications capable of performing and scaling. Go is a modern cross-platform programming language that is very powerful yet simple; it is an excellent choice for microservices and cloud applications. Go is gaining more and more popularity, and becoming a very attractive skill. This book starts by covering the software architectural patterns of cloud applications, as well as practical concepts regarding how to scale, distribute, and deploy those applications. You will also learn how to build a JavaScript-based front-end for your application, using TypeScript and React. From there, we dive into commercial cloud offerings by covering AWS. Finally, we conclude our book by providing some overviews of other concepts and technologies that you can explore, to move from where the book leaves off.

Basic React principles


A React application is built from Components. A component is a JavaScript class that accepts a set of values (called properties, or in short, props) and returns a tree of DOM elements that can be rendered by the browser.

Consider the following easy example. We will start with the plain JavaScript implementation and show you how to add static typing using TypeScript later:

class HelloWorld extends React.Component { 
  render() { 
    return <div className="greeting"> 
      <h1>Hello {this.props.name}!</h1> 
    </div>; 
  } 
} 

Even if you are used to JavaScript, the syntax will probably seem new to you. Technically, the preceding code example is not plain JavaScript (any browser would refuse to actually run this code), but JSX. JSX is a special syntax extension to JavaScript that allows you to directly define DOM elements using their respective HTML representation. This makes defining React components much easier. Without using JSX, the preceding...
