Chapter 1. Unleashing React Applications with MERN

React may have opened up new frontiers for frontend web development and changed the way we program JavaScript user interfaces, but we still need a solid backend to build a complete web application. Although there are myriad options when selecting backend technologies, the benefits and appeal of using a full JavaScript stack are undeniable, especially when there are robust and widely-adopted backend technologies such as Node, Express, and MongoDB. Combining the potential of React with these industry-tested, server-side technologies creates a diverse array of possibilities when developing real-world web applications.

This book guides you through setting up for MERN-based web development, to building real-world web applications of varying complexities.

Before diving into the development of these web applications, we are going to answer the following questions in this chapter to set the context for using MERN:

  • What is the MERN stack?
  • Why is MERN relevant today?
  • When is MERN a good fit for developing web apps?
  • How is this book organized to help master MERN?
 

MERN stack


MongoDB, Express, React, and Node are used in tandem to build web applications and make up the MERN stack. In this lineup, Node and Express bind the web backend together, MongoDB serves as the NoSQL database, and React makes the frontend that the user sees and interacts with.

All four of these technologies are free, open-source, cross-platform, and JavaScript-based, with extensive community and industry support. Each technology has a unique set of attributes, which when integrated together make a simple but effective full JavaScript stack for web development.

Node

Node was developed as a JavaScript runtime environment built on Chrome's V8 JavaScript engine. Node made it possible to start using JavaScript on the server-side to build a variety of tools and applications beyond previous use cases that were limited to within a browser.

Node has an event-driven architecture capable of asynchronous, non-blocking I/O. Its unique non-blocking I/O model eliminates the waiting approach to serving requests. This allows building scalable and lightweight real-time web applications that can efficiently handle many requests.

Node's default package management system, the Node package manager or npm, comes bundled with the Node installation. Npm gives access to hundreds of thousands of reusable Node packages built by developers all over the world and boasts that it is currently the largest ecosystem of open source libraries in the world.

Note

Learn more about Node at https://nodejs.org/en/ and browse through available npm modules at https://www.npmjs.com/.

Express

Express is a basic framework for building web applications and APIs with a Node server. It provides a simple layer of fundamental web application features that complements Node.

In any web application developed with Node, Express can be used as a routing and middleware web framework that has minimal functionality of its own—an Express application is essentially a series of middleware function calls.

Note

Middleware functions are functions that have access to the HTTP request and response objects, and also the next middleware function in the web application's request-response cycle.

It is possible to insert almost any compatible middleware of your choice into the request handling chain, in almost any order, making Express very flexible to work with.

Note

Find out what is possible with Express.js at expressjs.com.

MongoDB

MongoDB is a top choice when deciding on a NoSQL database for any application. It is a document-oriented database that stores data in flexible, JSON-like documents. This means fields can vary from document to document and data models can evolve over time in response to changing application requirements.

Applications that place a high priority on availability and scalability benefit from MongoDB's distributed architecture features. It comes with built-in support for high availability, horizontal scaling using sharding, and multi-data center scalability across geographic distributions.

MongoDB has an expressive query language, enabling ad hoc queries, indexing for fast lookups, and real-time aggregation that provides powerful ways to access and analyze data while maintaining performance even when data size grows exponentially.

Note

React

React is a declarative and component-based JavaScript library for building user interfaces. Its declarative and modular nature makes it easy for developers to create and maintain reusable, interactive, and complex user interfaces.

Large applications that display a lot of changing data can be fast and responsive if built with React, as it takes care of efficiently updating and rendering just the right UI components when specific data changes. React does this efficient rendering with its notable implementation of a virtual DOM, setting React apart from other web UI libraries that handle page updates with expensive manipulations directly in the browser's DOM.

Developing user interfaces using React also forces frontend programmers to write well-reasoned and modular code that is reusable, easier to debug, test, and extend.

Note

Since all four technologies are JavaScript-based, these are inherently optimized for integration. However, how these are actually put together in practice to form the MERN stack can vary based on application requirements and developer preferences, making MERN customizable and extensible to specific needs.

 

Relevance of MERN


JavaScript has come a long way since its inception and it is ever-growing. The MERN stack technologies have challenged the status quo and broken new ground for what is possible with JavaScript. But when it comes to developing real-world applications that need to be sustainable, is it a worthy choice? Some of the reasons that make a strong case for choosing MERN for your next web application are briefly outlined in the following.

Consistency across the technology stack

As JavaScript is used throughout, developers don't need to learn and change gears frequently to work with very different technologies. This also enables better communication and understanding across teams working on different parts of the web application.

Less time to learn, develop, deploy, and extend

Consistency across the stack also makes it easy to learn and work with MERN, reducing the overhead of adopting a new stack and the time to develop a working product. Once the working base of a MERN application is set up and a workflow established, it takes less effort to replicate, further develop, and extend any application.

Widely adopted in the industry

Organizations of all sizes have been adopting the technologies in this stack based on their needs because they can build applications faster, handle highly diverse requirements, and manage applications more efficiently at scale.

Community support and growth

Developer communities surrounding the very popular MERN stack technologies are quite diverse and growing on a regular basis. With lots of people continuously using, fixing, updating, and willing to help grow these technologies, the support system will remain strong for the foreseeable future. These technologies will continue to be maintained, and resources are very likely to be available in terms of documentation, add-on libraries, and technical support.

The ease and benefits of using these technologies are already widely recognized. Because of the high-profile companies that continue adoption and adaptation, and the growing number of people contributing to the code bases, providing support, and creating resources, technologies in the MERN stack will continue to be relevant for a long time to come.

 

Range of MERN applications


Given the unique features attributed to each technology, along with the ease of extending functionalities of this stack by integrating other technologies, the range of applications that can be built with this stack is actually quite diverse.

These days, web applications are, by default, expected to be rich client apps that are immersive, interactive, and don't fall short on performance and availability. The grouping of MERN strengths makes it perfect for developing web applications that meet these very aspects and demands.

Moreover, novel and upcoming attributes of some of these technologies, such as low-level operation manipulation with Node, large file streaming capabilities with MongoDB GridFS, and virtual reality features on the web using React 360, make it possible to build even more complex and unique applications with MERN.

It may seem reasonable to pick specific features in the MERN technologies, and argue why these don't work for certain applications. But given the versatile nature of how a MERN stack can come together and be extended; these concerns can be addressed in MERN on a case-by-case basis. In this book, we will demonstrate how to make such considerations when faced with specific requirements and demands in the application being built.

MERN applications developed in this book

To demonstrate the breadth of possibilities with MERN and how you can easily start building a web application with varying features, this book will showcase everyday use web applications alongside complex and rare web experiences:

The preceding screenshot gives a glimpse of the four different MERN applications developed in the rest of this book 

Social media platform

For the first MERN application, we will build a basic social media application inspired by Twitter and Facebook. This social media platform will implement simple features such as post sharing, liking and commenting, following friends, and an aggregated news feed.

Online marketplace

E-commerce web applications of all sorts are abundant on the internet, and these will not go out of style anytime soon. Using MERN, we will build an online marketplace application covering core aspects, such as support for seller accounts, product listings, a shopping cart for customers, and payment processing.

Media streaming application

To test out some advanced MERN capabilities, a more immersive application, such as a media streaming application, is the next pick. Inspired by features from Netflix and YouTube, this application will implement content uploading and viewing capabilities with a media content upload feature for content providers, and real-time content streaming for viewers.

VR game for the web

The release of React 360 makes it possible to apply web VR capabilities to React user interfaces. We will explore how to create rare web experiences with React 360 in MERN by putting together a basic virtual reality game application for the web. Users will be able to make and play VR games, where each game will have animated VR objects that the player can collect to complete the game.

 

Book structure


This book aims to help JavaScript developers who have zero-to-some experience with the MERN stack, to set up and start developing web applications of varying complexity. It includes guidelines for building out and running the different applications supplemented with code snippets and explanations of key concepts.

The book is organized into five parts, progressing from basic to advanced topics, taking you on a journey of building MERN from the ground up, then using it to develop different applications with simple to complex features, while demonstrating how to extend the capabilities of the MERN stack based on application requirements.

Getting started with MERN

Chapter 1, Unleashing React Applications with MERN and Chapter 2, Preparing the Development Environment set the context for developing web applications in a MERN stack and guide you through setting up your development environment.

Building MERN from the ground up – a skeleton application

Chapter 3, Building a Backend with MongoDB, Express, and Node and Chapter 4, Adding a React Frontend to Complete MERN show how to bring the MERN stack technologies together to form a skeleton web application with minimal and basic features. This skeletal MERN application acts as a base for the four main applications developed in the rest of the book.

Developing basic web applications with MERN

In this part, you will become familiar with the core attributes of a MERN stack web application by building out two real-world applications—a simple social media platform in Chapter 5,Starting with a Simple Social Media Application, and an online marketplace in Chapter 6, Exercising New MERN Skills with an Online Marketplace and Chapter 7, Extending the Marketplace for Orders and Payments.

Advancing to complex MERN applications

Chapter 8, Building a Media Streaming Application, Chapter 9, Customizing Media Player and Improve SEO, Chapter 10, Developing a Web-Based VR Game, and Chapter 11, Making the VR Game Dynamic using MERN show how this stack can be used to develop applications with more complex and immersive features, such as media streaming and virtual reality using React 360.

Going forward with MERN

Finally Chapter 12, Following Best Practices and Developing MERN Further wraps up the preceding chapters and applications developed by expanding on best practices to follow to make successful MERN applications, suggesting improvements and further developments.

You may choose to use the book out of the prescribed order based on your experience level and preference. A developer who is very new to MERN can follow the path set out in the book. For a more seasoned JS developer, the chapters in the Building MERN from the ground up - a skeleton application section would be a good place to start setting up the base application, then pick any of the four applications to build and extend.

 

Getting the most out of this book


The content in this book is practical-oriented and covers the implementation steps, code, and concepts relevant to building out each MERN application. It is recommended that, rather than attempting to just read through the chapters, you should run the relevant code in parallel, and browse through the application features while following the explanations in the book.

Chapters that discuss code implementations will point to GitHub repositories containing the complete code with instructions on how to run the code. You can pull the code, install, and run it before reading through the chapter:

You may consider the recommended following steps outlined to follow the implementations in this book:

  • Before diving into the implementation details discussed in the chapter, pull code from the relevant GitHub repository
  • Follow instructions with the code to install and run the application
  • Browse the features of the running application, while reading the feature descriptions in the relevant chapter
  • With the code running in development mode and also open in the editor, refer to the steps and explanations in the book to get a deeper understanding of the implementations

This book aims to provide a quick onboarding with working code for each application. You can experiment with, improve, and extend this code as desired. For an active learning experience, you are encouraged to refactor and modify the code while following the book. In some examples, the book chooses verbose code over succinct and cleaner code because it is easier to reason about for newcomers. In some other implementations, the book sticks with more widely used and traditional conventions over modern and upcoming JavaScript conventions. This is done to minimize disparity when you refer to online resources and documentation while researching the discussed technologies and concepts on your own. These instances where the code in the book can be updated, serve as good opportunities to explore and grow skills beyond what is covered in the book. 

 

Summary


In this chapter, we discovered the context for developing web applications in the MERN stack, and how this book will help you develop with this stack.

MERN stack projects integrate MongoDB, Express, React, and Node to build web applications. Each of the technologies in this stack has made relevant strides in the world of web development. These are widely adopted and continue to improve with the support of growing communities. It is possible to develop MERN applications with diverse requirements, ranging from everyday use applications to more complex web experiences. The practical-oriented approach in this book can be used to grow MERN skills from basic to advanced, or for diving right into building the more complex applications.

In the next chapter, we will start gearing up for MERN application development by setting up the development environment.
