Extending Microsoft Power Apps with Power Apps Component Framework

By: Danish Naglekar

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.

Setting up a testing framework

We will be using Jest as our testing framework tool. It was initially developed for JavaScript, hence the name Jest. But today it works with various projects using TypeScript, React, Node.js, Angular, and so on.

First, we need to install Jest in our project using the following command:

npm install jest @types/jest ts-jest --save-dev

Similar to the previous section, we use the --save-dev attribute as this activity will only be performed during the development phase and has no effect on running the application.

Now, let’s add a folder named tests and create a configuration file named jest.config.js in the root directory of your PCF project for Jest to run its test cases. The following is the sample configuration file for Jest:

jest.config.js

module.exports = {

  verbose: true,

  rootDir: “.”,

  testMatch: [“<rootDir>/tests/*.(spec|test).(j|t)s”],
