Overview of this book

Power Apps Component Framework is used by professional developers to extend the capabilities of model-driven and canvas apps. Extending Microsoft Power Apps with Power Apps Component Framework will take you through the basic as well as advanced topics using practical examples. The book starts by helping you understand the fundamentals of the framework, its lifecycle, and the tools that you'll use to build code components using best practices and file management guidelines. You'll then learn how to extend Power Apps step by step and apply the principles and concepts covered in the book to build code components for field type attributes. The book covers different ways of debugging code components and guides you through the process of building code components for datasets. You'll also explore the functions and methods provided by the framework to enhance your controls using powerful sets of libraries and extensions. As you advance, you'll get to grips with creating and managing authentication profiles, discover different ways of deploying code components, and configure code components in model-driven and canvas apps. Finally, you'll learn some of the important features of the framework and learn modern web development practices. By the end of this Power Apps book, you'll be able to build, debug, enrich, and deploy code components confidently.

Using Lint and Prettier

When you write code, if it is not readable or each developer uses their own coding styles, then the code review might be affected, which can lead to the creation of bugs and issues. This is where Lint and Prettier come in handy.

Understanding the process of linting your code

Linting is an automated process to check your code for programming and styling errors. This process is accomplished by using lint tools, also called linters. When we are dealing with TypeScript, there are two linters available to us: one is called ESLint and the other is TSLint. As TSLint is now deprecated, we will only be working with ESLint.

First, we will initialize a new PCF project. Once the project is initialized, install all the required ESLint packages using the following command in the VS Code integrated terminal as shown in the screenshot:

We are using the --save-dev attribute because these...
