With Power Apps component framework, you can create your own code components to improve the user experience in Model-driven and canvas apps. Even though you can create your own components, there are some limitations that restrict developers implementing some features in the code components. Below are some of the limitations:
Microsoft Dataverse dependent APIs, including WebAPI, are not available for canvas applications yet. For individual API availability, see Power Apps component framework API reference.
Code components should bundle all the code including external library content into the primary code bundle. To see an example of how the Power Apps command line interface can help with bundling your external library content into a component-specific bundle, see Angular flip component example.
Support for shared libraries across components using library nodes in the component manifest is currently in public preview. More information: React controls & platform libraries (Preview).
Code components should not use the HTML web storage objects, like
window.sessionStorage, to store data. Data stored locally on the user's browser or mobile client is not secure and not guaranteed to be available reliably.
