20 Essential Code Review Points for Creating Efficient and Maintainable Salesforce Flows

1.  Use descriptive variable names: Use variable names that accurately describe what they represent. Avoid using abbreviations or vague names that may cause confusion.
2. Keep your flows simple: Break your flow down into smaller, more manageable components. Avoid creating overly complex flows that are difficult to debug and maintain.
3. Use consistent formatting: Follow consistent formatting and naming conventions throughout your flow. This will make it easier for others to understand and follow your code.
4. Include comments: Include comments in your flow to explain complex logic, assumptions, and any unusual implementation details.
5. Avoid hard-coding values: Instead of hard-coding values, use variables or custom labels to store data that may change in the future.
6. Test your flow thoroughly: Use test cases to ensure your flow functions as expected. Consider testing for various inputs and edge cases.
7. Use fault connectors: Use fault connectors to handle errors and exceptions in your flow. This will help prevent unexpected errors and ensure a smooth user experience.
8. Follow best practices: Review Salesforce's best practices for flow development to ensure you are following recommended design patterns and development practices.
9. Use record variables: Use record variables to store and manipulate record data in your flow. This will simplify your flow and make it more efficient.
10. Consider performance: Be mindful of performance considerations, such as the number of decision elements, record lookups, and external API calls. Optimize your flow for speed and efficiency where possible.
11. Follow naming conventions: Use consistent naming conventions for flow screens, flows, and resources, such as variables and formula fields.
12. Use sub-flows: Use sub-flows to encapsulate reusable logic that you can call from other flows.
13. Avoid using hard-coded IDs: Avoid using hard-coded record IDs in your flow. Instead, use formulas to dynamically retrieve record IDs.
14. Use decision elements sparingly: Avoid using too many decision elements in your flow. Consider using formula elements or invocable actions to reduce the number of decision elements.
15. Use dynamic choice elements: Use dynamic choice elements to reduce the number of decision elements in your flow. This allows you to define the criteria for each choice at runtime.
16. Limit the number of elements per flow: Try to limit the number of elements in your flow to reduce complexity and increase performance.
17. Use invocable actions: Use invocable actions to encapsulate reusable logic that you can call from other flows or Apex code.
18. Consider security implications: Be mindful of security implications when designing your flow. Ensure that only authorized users can access or modify sensitive data.
19. Consider exception handling: Consider how your flow will handle exceptions, such as data validation errors or API timeouts.
20. Use custom metadata types: Use custom metadata types to store configuration data that may change frequently or need to be shared across multiple flows. This will simplify maintenance and reduce duplication of effort.
