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.

Querying for data using Mongoose query selectors

Instead of SQL to query data from the database, Mongoose relies on using the JavaScript method chaining to build logical queries, which will be sent over to MongoDB once executed. The model API already exposed us to some rudimentary queries through methods like find and where, but we can expand upon those greatly with Mongoose's query API methods.

How to do it...

Let's follow these steps to add query parameters to our Express /api/post REST endpoint to support pagination. We will also implement some advanced filtering queries, including date range filtering to our API:

  1. First, we'll extend the list method of our /middleware/rest.js middleware to parse query parameters...
