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.

Understanding the importance of the getOutputs method

Since we looked at the getOutputs method briefly in the previous section, we will look at why it is important. This method is invoked when the component has modified the bound properties. The values for such properties should be communicated back to the host.

Using the same example library we used previously, observe that we are returning an updated textbox value back to the host via fieldProp, which is a bound property in the getOutputs method. This can also be validated by using the Data Output section of the test harness. If any updated value is returned to its host, then you should see such values under this section. When you initiate a test of the example library and change the value in the text box provided by the component, you can observe the changed value in the Data Outputs section, as shown in the following screenshot:
