Preface

About

This section briefly introduces the author, the coverage of this book, the technical skills you'll need to get started, and the hardware and software requirements required to complete all of the included activities and exercises.

About the Book

MongoDB, Express, Angular, and Node.js Fundamentals begins by demystifying the MEAN architecture. You will take a look at the features of the JavaScript technologies, frameworks, and libraries that make up the MEAN stack. You will learn how to develop a RESTful API using Node.js, Express.js, and MongoDB Atlas. You will also learn how to build a blogging application using the MEAN stack. Next, you will learn about authentication using the MEAN stack, and explore the features of Angular, such as pipes, reactive forms, modules, optimizing apps, animations, and unit testing, and much more. By the end of the book, you will have all the knowledge you need to become a pro at developing efficient web applications using JavaScript technologies.

Conventions

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We use var fs = require('fs') to declare fs (a filesystem variable) and assign the filesystem module to it."

A block of code is set as follows:

interface LoginResponse {

accessToken: string;

accessExpiration: number;

}

this.http.post<LoginResponse>('api/login', {

login: 'foo',

password: 'bar'

}).subscribe(data => {

console.log(data.accessToken, data.accessExpiration);

});

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Create the Post Create/Edit form components"
