Component reuse in the Power Platform is the process of using the same components or piece of programming code for multiple purposes or in different situations. Leveraging component reuse helps to reduce overall development time, and increase efficiency and consistency while decreasing the likelihood of bugs.
The main components that can be reused in Power Platform are:
- Canvas App Components
- Model-Driven App Components
- Power Automate Flows
- Power Virtual Agents Chatbots
Before you proceed with component reuse, it is essential to understand what each component does:
- Canvas App Components: These are reusable blocks of code which can be utilized across different screens and apps. They can be either standard or custom components. Examples include input fields, buttons, and labels that are often used in apps.
- Model-Driven App Components: In model-driven apps, you can reuse dashboards, views, charts, forms, and business process flows. For instance, you may create a form that is used across multiple entities or reuse the same dashboard in multiple apps.
- Power Automate Flows: These are automated workflows between your favorite apps and services to synchronize files, get notifications, collect data, and more. They can be used across different apps and situations.
- Power Virtual Agents Chatbots: These are conversational agents, which guide users through processes in a natural and interactive manner, and can be reused in different apps or situations.
Identifying Opportunities for Component Reuse
Identifying opportunities for component reuse is not only about saving time but also about ensuring consistency and preventing errors. Here are some scenarios when component reuse could be highly beneficial:
- Common Design Elements: When the design contains similar repeating elements or structures such as buttons, cards or banners. Creating a single component in its most generic form saves time and facilitates changes in the future.
- Data Processing: If data is being processed in the same way across different apps – for example, date formatting or string conversion – then a component that performs these actions can be used.
- Standard User Inputs: Forms, buttons, and similar input controls are common components. A single component can be designed to handle all necessary bounded contexts and can be reused wherever inputs are required.
Case in point, suppose you want to use an input form with fields like ‘Name’, ‘Email’, and ‘Contact’ across multiple apps. Instead of creating this form for every app, you can create a Canvas App component and reuse it.
The process can go as follows:
- Go to the Power Apps portal, under Apps, select Canvas App and start creating an app.
- Select ‘Components tab’ > ‘New Component’.
- In the new component screen, add the required input fields and graphical elements.
- Save and publish the component.
Now, you can use this component in your other apps by importing it, ensuring consistency, and saving you time.

When identifying opportunities for component reuse, a component with complex logic is not suitable for reuse.
- A) True
- B) False
Answer: B) False
Explanation: Even the components with complex logic can be reusable depending upon the commonality in functionalities required in different apps or different sections of the same app.
What is the main benefit of component reuse in Power Platform App Maker?
- A) Reduced development time
- B) Increased complexity
- C) Limited customization
- D) Increased cost
Answer: A) Reduced development time
Explanation: By reusing the components, one doesn’t need to code the same functionalities repeatedly which significantly reduces the development time.
One should only consider component reuse if the same feature will be used in the majority of the application?
- A) True
- B) False
Answer: B) False
Explanation: Even if a feature will not be used in the majority of the application, it can still be beneficial to consider component reuse if the same feature is needed multiple times throughout the application.
True or False: A well-designed component should be self-contained and should not interact with other components.
- Answer: True
Explanation: A well-designed component should indeed be self-contained to maximize its reusability. However, this doesn’t mean it cannot interact with other components at all, it just needs to ensure minimal dependencies.
What factors should you consider when identifying opportunities for component reuse? (Select all that apply)
- A) Complexity of the component
- B) Frequency of use
- C) Potential for future use
- D) Cost of development
Answer: A) Complexity of the component, B) Frequency of use, C) Potential for future use, D) Cost of development
Explanation: All these factors influence the decision to reuse a component. Reusing a component could save time and complexity, increase efficiency, and reduce development costs.
Even after a component is created, further customization is possible.
- A) True
- B) False
Answer: A) True
Explanation: After a component is created, it can still be customized further according to the specific needs of different sections of an app.
Reusability of components reduces the need for…
- A) Testing
- B) Debugging
- C) Both A and B
- D) None of the above
Answer: C) Both A and B
Explanation: Component reusability reduces both testing and debugging as the reused components have already been tested and debugged before.
Reusability of components can cause issues in terms of coherence and consistency throughout an app.
- A) True
- B) False
Answer: B) False
Explanation: Actually, reusability of components often increases coherence and consistency as the reused components provide the same functionalities and appearances wherever they are used in an app.
