MEAN Cookbook

By: Nicholas McClay

Overview of this book

The MEAN Stack is a framework for web application development using JavaScript-based technologies; MongoDB, Express, Angular, and Node.js. If you want to expand your understanding of using JavaScript to produce a fully functional standalone web application, including the web server, user interface, and database, then this book can help guide you through that transition. This book begins by configuring the frontend of the MEAN stack web application using the Angular JavaScript framework. We then implement common user interface enhancements before moving on to configuring the server layer of our MEAN stack web application using Express for our backend APIs. You will learn to configure the database layer of your MEAN stack web application using MongoDB and the Mongoose framework, including modeling relationships between documents. You will explore advanced topics such as optimizing your web application using WebPack as well as the use of automated testing with the Mocha and Chai frameworks. By the end of the book, you should have acquired a level of proficiency that allows you to confidently build a full production-ready and scalable MEAN stack application.

The login page represents the other half of our user authentication feature. We have an authentication API; now, we need the form to input our username and password. We will build this user interface in Angular using ngForm, our current user service, and Observables for data-binding.

Getting ready

Before we can get started building our login page, we will need to generate a new login component to handle our login user experience. We will create that using Angular CLI's generate command:

ng generate component login

We will also need to remove any previous usage of the CurrentUserService service from our application. The main place we had used it previously was the /src/app/app.module...
