Overview of this book

Almost a decade after the release of Node.js, the tooling used by frontend developers is fully embracing this cross-platform JavaScript runtime, which is sadly often limited to server-side web development. This is where this Node.js book comes in, showing you what this popular runtime has to offer and how you can unlock its full potential to create frontend-focused web apps. You’ll begin by learning the basics and internals of Node.js, before discovering how to divide your code into modules and packages. Next, you’ll get to grips with the most popular package managers and their uses and find out how to use TypeScript and other JavaScript variants with Node.js. Knowing which tool to use when is crucial, so this book helps you understand all the available state-of-the-art tools in Node.js. You’ll interact with linters such as ESLint and formatters such as Prettier. As you advance, you’ll become well-versed with the Swiss Army Knife for frontend developers – the bundler. You’ll also explore various testing utilities, such as Jest, for code quality verification. Finally, you’ll be able to publish your code in reusable packages with ease. By the end of this web development book, you’ll have gained the knowledge to confidently choose the right code structure for your repositories with all that you’ve learned about monorepos.

Considering the testing pyramid

Over the years, more and more types of software testing have been identified and added to the standard repertoire of software projects and testing professionals such as quality assurance engineers. A powerful tool to categorize and order the most common types of software testing is the testing pyramid.

The testing pyramid arranges the different types of testing by their visibility and effort. Higher layers of the pyramid require more effort but have greater visibility. Tests that are placed in the lower layers of the pyramid should be written a lot more – after all, these are the foundations of the pyramid.

An illustration of the testing pyramid is shown in Figure 7.1. The basis of the testing pyramid is formed by unit tests, which provide enough reliability to run components and integration tests on top of them later. Finally, UI tests (quite often referred to as end-to-end tests) can be run to verify that the solution works for end users...
