Full-Stack React Projects

By: Shama Hoque

Overview of this book

The benefits of using a full JavaScript stack for web development are undeniable, especially when robust and widely adopted technologies such as React, Node, and Express and are available. Combining the power of React with industry-tested, server-side technologies, such as Node, Express, and MongoDB, creates a diverse array of possibilities when developing real-world web applications. This book guides you through preparing the development environment for MERN stack-based web development, to creating a basic skeleton application and extending it to build four different web applications. These applications include a social media, an online marketplace, a media streaming, and a web-based game application with virtual reality features. While learning to set up the stack and developing a diverse range of applications with this book, you will grasp the inner workings of the MERN stack, extend its capabilities for complex features, and gain actionable knowledge of how to prepare MERN-based applications to meet the growing demands of real-world web applications.

Optimizing the bundle size


As you develop and grow a MERN application, chances are the size of the bundles produced with Webpack will also grow, especially if large third-party libraries are used. Larger bundle sizes will effect performance and increase the initial load time of the application. We can make changes in the code to ensure we don’t end up with large bundles and also utilize features packed in Webpack 4 to help optimize bundling. In this section, we will highlight some key concepts that can give us control in producing smaller bundles and decreasing load time.

Note

Before going into the code to update it for bundle size optimization, you can also get familiar with the default optimization options that are now part of Webpack 4. In the MERN applications, we used the mode config to utilize the default settings for both development and production mode.
