TL;DR

Added code editing capabilities to the UI builder, allowing users to modify existing components through chat instructions.

What changed?

  • Added editApp function in lib/openai.ts to handle code modifications
  • Created new prompt templates for editing in lib/prompts.ts
  • Extended the component schema to support editing instructions and existing files
  • Implemented file merging logic to combine updated files with existing ones
  • Updated the chat interface to send edit requests with current files
  • Added session storage to persist builder results
  • Enhanced logging for better debugging of edit operations

How to test?

  1. Generate a component using the UI builder
  2. Use the chat interface to request changes (e.g., "Add a dark mode toggle")
  3. Verify that the component updates according to your instructions
  4. Check that the changes persist when refreshing the page (via sessionStorage)
  5. Examine the console logs to verify the edit flow is working correctly

Why make this change?

This enhancement significantly improves the user experience by allowing iterative refinement of generated components without starting from scratch. Users can now have a conversation with the AI to progressively improve their components, making the tool more flexible and powerful for real-world development workflows.

🧪 Benchify Analysis of PR 29

The test results show a mixed picture. Several properties related to file merging and ReactAppUserPrompt function passed successfully, indicating that the code can handle various file input scenarios and generate correct prompts. However, two properties failed, highlighting issues with createEditUserPrompt function.

The failing tests indicate that the createEditUserPrompt function does not consistently produce the expected output format when given an array of files and an edit instruction. Specifically, the output does not always start with the correct introductory statement, format the file contents correctly, or include the edit instruction section.

Additionally, the test that checks for edge cases, such as empty files array or invalid edit instruction, also failed, suggesting that the function may not be robust enough to handle these scenarios.

To improve the code, it's recommended to review the createEditUserPrompt function and ensure it produces the correct output format for various input scenarios, including edge cases.

Your property-based test has passed! This test ensures that the mergeFiles function returns an array of files with unique paths. The test generated an example with two arrays of files, existingFiles and updatedFiles, and successfully verified that the merged result contains no duplicate paths. The test's success indicates that the mergeFiles function is correctly handling file merging and maintaining path uniqueness.

✅ Implement Correct Override Logic for Merged Files

When merging files, updatedFiles should overwrite existingFiles based on matching path elements.

The property-based test has passed, indicating that the mergeFiles function correctly overwrites existing files with updated files based on matching path elements. The test successfully merged the provided existingFiles and updatedFiles arrays, and the resulting merged files contained the expected content from the updatedFiles array. This suggests that the overriding logic in the mergeFiles function is working as intended.

The test is failing because the output of the createEditUserPrompt function does not consistently start with the introductory statement "Here are the current files:\n\n" for the given input. The input consists of an array of objects with "path" and "content" properties, and an edit instruction string. The error is an AssertionError, indicating that the expectation of the output starting with the introductory statement was not met.

❌ Error Handling for Missing or Invalid Input

Here's a summary of the test results:

The test failed with a TypeError due to an unexpected usage of an instance of FrequencyArbitrary as a function. This issue occurred when processing an array of files with specific paths and contents, where the function createEditUserPrompt was expected to handle cases with an empty 'files' array or invalid 'editInstruction' strings. To resolve this, review the implementation of the createEditUserPrompt function and ensure it correctly handles these edge cases.

Stack Trace
TypeError: p is not a function. (In 'p(...t)', 'p' is an instance of FrequencyArbitrary)
