Power Apps: Building a Naming Refactoring tool for Power Apps

Power Apps, a versatile platform for building business applications, often faces challenges related to naming conventions. In a recent YouTube video by Microsoft, a demonstration was provided on how to build a Naming Refactoring Tool for Power Apps. This tool aims to streamline and refactor control names in Power Apps Canvas apps, enhancing organization and maintainability. The video, presented by Jean Paul Dosher, was part of the Power Platform community call on November 20, 2024. This article delves into the key aspects of the video, exploring the importance of naming conventions, the tools available, and the process of developing a refactoring tool.

Understanding Power Apps Naming Conventions

Implementing consistent naming conventions in Power Apps is crucial for improving code readability, maintainability, and collaboration. Before developing a Naming Refactoring Tool, it is essential to familiarize oneself with established naming conventions. These conventions typically include:

• Screen Names: Clearly describe the screen’s purpose in 2-3 words, ending with “Screen.” Use proper case, such as “Order Form Screen.”
• Control Names: Combine the control type, purpose, and screen name using camel case with underscores. For example, a text input for the first name on the Order Form Screen could be named txt_OrderForm_FirstName.
• Variable Names: Indicate the scope and purpose, using camel case without spaces. Prefix global variables with gbl and local variables with loc, such as gblUserEmail for a global variable holding the user’s email.
• Collection Names: Reflect the original data source and purpose, using camel case. For instance, colSpEmployees for a collection of employees from SharePoint.

These conventions serve as a guideline for developers, helping them maintain a structured and organized codebase. However, adhering to these conventions can be challenging, especially in large applications with numerous controls and variables.

Utilizing the Power Apps Source Code Tool

The Power Apps Source Code Tool is an invaluable resource for developers looking to refactor their applications. It allows developers to unpack .msapp files into a human-readable format, facilitating code reviews and bulk modifications. The process involves:

• Unpacking: Convert the .msapp file into source code using the tool.
• Editing: Modify control names directly in the source code files.
• Repacking: Compile the edited source code back into an .msapp file for use in Power Apps.

This approach enables efficient renaming of controls and variables across the entire app. By leveraging the Power Apps Source Code Tool, developers can ensure that their applications adhere to naming conventions, improving overall quality and maintainability.

Exploring Existing Refactoring Tools

In addition to the Power Apps Source Code Tool, there are several existing tools and frameworks that assist in refactoring Power Apps. These include:

• YAML Refactoring: Some developers have utilized YAML to streamline control name refactoring within Power Apps Canvas Apps.
• PowerApps Tooling: Microsoft’s PowerApps Tooling supports refactoring and may offer functionalities beneficial to tool development.

These tools provide developers with various options for automating the renaming process, reducing manual effort and minimizing errors. However, each tool has its own set of tradeoffs, and developers must carefully evaluate their needs before selecting the most suitable option.

Developing the Refactoring Tool

Building a Naming Refactoring Tool involves several key steps:

• Design: Outline the tool’s features, such as scanning for non-compliant names, suggesting standardized names, and automating the renaming process.
• Implementation: Develop the tool, possibly leveraging existing frameworks or creating custom scripts to automate the renaming process.
• Testing: Ensure the tool accurately identifies and renames controls without introducing errors.

The primary objective of the tool is to modify control names ending in suffixes like “_2,_5,_100….” (e.g., Icon5_2). By following these steps, developers can create a Naming Refactoring Tool that enhances the quality and maintainability of Power Apps applications.

Challenges and Conclusion

Developing a Naming Refactoring Tool is not without its challenges. One of the main obstacles is ensuring that the tool accurately identifies and renames controls without introducing errors. Additionally, developers must consider the tradeoffs involved in balancing different factors, such as automation versus manual intervention. Despite these challenges, the benefits of implementing a Naming Refactoring Tool are significant. It helps streamline the development process, reduces errors, and improves the overall quality of Power Apps applications. By adhering to naming conventions and utilizing available tools, developers can enhance the maintainability and readability of their code, ultimately leading to more efficient and effective applications.
