Most people try to use AI for Resolving Async Code Stalls with a single vague prompt and get generic results. This guide takes a different approach: 4 targeted stages, from Diagnose the Wall through Prevent Recurrence, each with a prompt that gives the AI exactly the context it needs. Async code generated by GitHub Copilot can sometimes fail to resolve or reject, causing the UI to remain in a perpetual loading state. This issue can lead to a poor user experience and hinder application performance. These prompts help developers identify and fix the problem, ensuring smooth and responsive UI interactions. Works with ChatGPT, Claude, and Gemini.

Diagnose the Wall

Identify the specific async function causing the issue and understand its context.

Identify Problematic Function

Please analyze the following async function: [PASTE FUNCTION]. Identify any potential issues that could prevent the function from resolving or rejecting as expected.

Provide a detailed explanation of your findings and suggest possible solutions to address the identified problems.

Diagnose the Wall

Check Promise Handling

Examine the following code snippet for promise handling: [PASTE SNIPPET]. Identify any instances where resolve or reject calls are missing, which could potentially lead to an infinite loading state.

Diagnose the Wall

Analyze Await Usage

Please analyze the following section of code: [PASTE CODE]. Identify any potential misuses of the 'await' keyword that could result in unresolved promises. Provide a detailed explanation of each misuse you find, including the specific lines of code where the issues occur, the potential impact on the application's performance or functionality, and suggestions for how to correct these issues. Additionally, summarize best practices for using 'await' effectively in asynchronous programming.

Diagnose the Wall

Review Function Dependencies

Please review the following dependencies for my async function: [PASTE DEPENDENCIES]. Analyze each dependency to determine if any could potentially cause the function to hang indefinitely.

In the following async function: [PASTE FUNCTION], identify the appropriate location to add a resolve call to ensure that the function completes successfully. Explain the reasoning behind your choice and describe how this addition will impact the function's behavior. Additionally, provide an example of how the function should look after the resolve call has been added, highlighting any changes made to the original code.

Isolate and Fix

Implement Reject Logic

Please review the following code: [PASTE CODE]. Identify the areas where reject logic can be effectively implemented to handle errors in a robust manner. Provide specific recommendations on how to structure the reject logic, including any necessary error messages or fallback procedures. Additionally, explain the potential impact of these changes on the overall functionality and reliability of the code.

Isolate and Fix

Refactor Await Usage

Please analyze the following async code: [PASTE CODE]. I need your help to identify the specific areas where the await usage may cause the code to hang. Provide a detailed explanation of the issues you find and suggest a refactored version of the code that prevents these hanging states. Additionally, outline best practices for using await in async functions to ensure smooth execution and performance.

Isolate and Fix

Enhance Error Handling

Please review the following function: [PASTE FUNCTION]. Identify potential issues in the current error handling implementation and suggest specific improvements to ensure that errors are resolved or rejected correctly. Explain how these changes will enhance the reliability and robustness of the function. Additionally, provide examples of how to implement these improvements in the code, including any necessary adjustments to the function's structure or logic.

Isolate and Fix

Debug Dependency Issues

Please analyze the following dependencies: [PASTE DEPENDENCIES]. Identify any potential issues that could cause the async function to stall and provide specific recommendations on how to modify these dependencies to improve performance. Include details on any changes in the code structure, version updates, or alternative libraries that could be used. Additionally, explain how these modifications will enhance the overall functionality and responsiveness of the async function.

Isolate and Fix

Verify the Resolution

Ensure the async code now resolves or rejects as expected, eliminating the infinite loading state.

Test Resolve Path

Please test the following updated async function: [PASTE FUNCTION]. Ensure that it resolves correctly and does not hang during execution. Provide a detailed report on the outcome, including any error messages or unexpected behavior encountered. Additionally, include the time taken for the function to resolve and any relevant observations about its performance.

Verify the Resolution

Check Reject Path

Please check the following code for proper rejection handling when an error occurs: [PASTE CODE]. I need you to run the code and confirm that it rejects as expected under error conditions. Additionally, provide a brief explanation of how the rejection is handled, including any error messages that are returned and the conditions that trigger the rejection. If there are any issues or unexpected behaviors, please outline them clearly.

Verify the Resolution

Simulate Error Conditions

Please simulate error conditions for the following function: [PASTE FUNCTION]. Introduce a specific error scenario and evaluate how the function responds. Does it handle the error gracefully and reject appropriately? Provide a detailed analysis of the function's error handling, including any potential improvements that could enhance its robustness.

Verify the Resolution

Validate Await Changes

Please validate the following refactored code: [PASTE CODE]. Check that all await statements are functioning correctly and do not lead to any unresolved promises. Provide a detailed analysis of how the changes improve the code's performance and reliability, and suggest any further improvements if necessary. Additionally, include examples of potential edge cases that could arise and how they would be handled in this context.

Verify the Resolution

Confirm Dependency Fixes

Please run the function using the following dependencies: [PASTE DEPENDENCIES]. After executing the function, check if it completes successfully without hanging or encountering any dependency-related issues. Provide a detailed report on the execution results, including any error messages or warnings that may appear, and confirm whether the dependency fixes have resolved the hanging issue.

Aim for a comprehensive guideline that can be easily adopted by a development team.

Prevent Recurrence

Design Project Guard

Design a project guard mechanism that automatically identifies and flags asynchronous functions that do not include resolve or reject calls. The guard should analyze the codebase for all async functions and generate a report detailing any instances where these calls are missing. Additionally, provide recommendations on how to implement resolve and reject calls effectively to ensure proper error handling and control flow. Format the output as a structured document with sections for findings, examples of problematic code, and suggested improvements.
