16-19: Excellent change to improve robustness across different execution contexts.The replacement of
instanceof ArraywithArray.isArrayis a great improvement. It addresses potential issues with prototype mismatches when the code runs in different execution contexts, such as within a VM for node rendering.The updated comments provide valuable context for this change, which enhances code maintainability.
Consider adding a brief mention of why
Array.isArrayis preferred overinstanceof Arrayin the comments. This could help developers who might not be familiar with the nuances of these checks. For example:// Must use Array.isArray instead of instanceof Array the history array is defined outside the vm if node renderer is used. // In this case, the Array prototype used to define the array is not the same as the one in the global scope inside the vm. +// Array.isArray is more reliable as it works correctly even when the array is created in a different realm or execution context.
18-18: Consider removing or replacing the Flow commentThe
// $FlowFixMecomment is typically used for Flow type checking, but this file appears to be using TypeScript. Consider removing this comment or replacing it with a TypeScript-specific comment if type assertion is needed.If type assertion is needed, you could use a TypeScript assertion comment instead:
// @ts-ignoreOr, preferably, use a type assertion:
if (!Array.isArray(console.history as any[])) {

29-29: Consider using a more specific type for the caught errorInstead of using
anyfor the caught error, consider using a more specific type. This will improve type safety and make the error handling more robust.You could use the
unknowntype and then narrow it down:} catch (e: unknown) { let errorMessage = 'An error occurred'; if (e instanceof Error) { errorMessage = e.message; } val = `${errorMessage}: ${arg}`; }This approach provides better type safety and more informative error messages.

14-19: Approve changes with a minor suggestion for comment improvement.The updated function signature and comment changes look good. Accepting
consoleHistoryas a parameter improves flexibility and testability. The explanation for usingArray.isArrayis valuable.Consider adding a brief explanation of why
consoleHistoryis now a parameter. For example:export function consoleReplay(consoleHistory: typeof console['history']): string { - // console.history is a global polyfill used in server rendering. + // consoleHistory is passed as a parameter to improve flexibility and testability. + // It replaces the global console.history polyfill previously used in server rendering. // Must use Array.isArray instead of instanceof Array the history array is defined outside the vm if node renderer is used. // In this case, the Array prototype used to define the array is not the same as the one in the global scope inside the vm.
44-45: Approve changes with a suggestion for JSDoc improvement.The updates to the
buildConsoleReplayfunction are consistent with the changes made toconsoleReplay. The modification improves the flexibility of the function.Consider adding a JSDoc comment to explain the purpose of the function and its parameter. For example:
/** * Builds a console replay script wrapped in script tags. * @param consoleHistory - The console history to be replayed. * @returns A string containing the console replay script wrapped in script tags. */ export default function buildConsoleReplay(consoleHistory: typeof console['history']): string { return RenderUtils.wrapInScriptTags('consoleReplayLog', consoleReplay(consoleHistory)); }

19-19: Approve the updated condition.The change from
instanceof ArraytoArray.isArrayis correct and consistent with the updated comment. Using theconsoleHistoryparameter instead ofconsole.historyaligns with the function signature change.

1-46: Summary of changes and alignment with PR objectives.The changes made to this file successfully contribute to the PR objective of adding support for replaying logs from async server operations. The modifications to
consoleReplayandbuildConsoleReplayfunctions improve flexibility and testability by accepting aconsoleHistoryparameter instead of relying on a global variable.Key improvements:
- Enhanced flexibility by parameterizing
consoleHistory.- Improved reliability by using
Array.isArrayinstead ofinstanceof Array.- Updated comments explaining the rationale behind the changes.
These changes will facilitate better debugging and monitoring of async server operations by allowing more controlled log replay.
To fully complete the PR objectives, please ensure that:
- Tests are added or updated to cover these changes.
- Documentation is updated to reflect the new function signatures and usage.
- The CHANGELOG is updated with an entry for this feature.

260-260: LGTM! Verify related changes and update tests/docs.The change to pass
console.historytobuildConsoleReplayaligns with the PR objective of supporting log replay for async server operations. This should improve debugging capabilities.Please ensure the following:
- The
buildConsoleReplayfunction (likely in another file) has been updated to accept and use thisconsole.historyparameter.- Unit tests have been updated or added to cover this change.
- Documentation has been updated to reflect this new functionality.
To verify the
buildConsoleReplayfunction update, you can run:Would you like assistance in updating the tests or documentation for this change?

12-12: LGTM! Consider adding JSDoc for the new parameter.The updated function signature improves flexibility by allowing a custom console history. The type and default value are appropriate.
Consider adding a JSDoc comment to describe the new
customConsoleHistoryparameter:/** * Generates a console replay script. * @param customConsoleHistory Optional custom console history to use instead of the global one. * @returns A string containing the console replay script. */ export function consoleReplay(customConsoleHistory: typeof console['history'] | undefined = undefined): string {
14-16: LGTM! Consider adding a comment for clarity.The implementation correctly uses the custom console history when provided and falls back to the global
console.historyotherwise. The use of the nullish coalescing operator is appropriate.Consider adding a brief comment to explain the fallback behavior:
// Use custom history if provided, otherwise fall back to global console.history const consoleHistory = customConsoleHistory ?? console.history; // Ensure consoleHistory is an array before processing if (!(Array.isArray(consoleHistory))) { return ''; }
47-48: LGTM! Consider adding JSDoc for consistency.The
buildConsoleReplayfunction has been correctly updated to accept and pass thecustomConsoleHistoryparameter toconsoleReplay. This change maintains consistency with theconsoleReplayfunction updates.For consistency with the
consoleReplayfunction, consider adding a JSDoc comment:/** * Builds a console replay script wrapped in script tags. * @param customConsoleHistory Optional custom console history to use instead of the global one. * @returns A string containing the wrapped console replay script. */ export default function buildConsoleReplay(customConsoleHistory: typeof console['history'] | undefined = undefined): string { return RenderUtils.wrapInScriptTags('consoleReplayLog', consoleReplay(customConsoleHistory)); }
Action Required: Update
buildConsoleReplayFunction CallsThe following instances of
buildConsoleReplayare called without thecustomConsoleHistoryparameter:
node_package/src/serverRenderReactComponent.tsnode_package/src/types/index.tsnode_package/src/ReactOnRails.ts(2 occurrences)Please update these calls to include the necessary
customConsoleHistoryparameter to ensure consistency with the new implementation.🔗 Analysis chain

1-48: Overall implementation looks good and aligns with PR objectives.The changes in this file successfully implement support for custom console history in both
consoleReplayandbuildConsoleReplayfunctions. This enhancement aligns well with the PR objective of adding support for replaying logs from async server operations.A few minor suggestions for improving documentation have been made, but the core functionality appears correct and consistent. The changes maintain backward compatibility while providing the flexibility to use custom console history when needed.
To fully meet the PR objectives:
- Ensure that the async server operations are correctly capturing their console output in a way that can be passed to these functions.
- Update any calling code to utilize the new
customConsoleHistoryparameter when replaying logs from async operations.- Add or update tests to cover these changes, as mentioned in the PR checklist.
- Update the documentation to reflect this new functionality.
- Add an entry to the CHANGELOG file describing this enhancement.
To verify the usage of these updated functions, please run the following script:
This will help ensure that any existing usage of these functions is updated to take advantage of the new
customConsoleHistoryparameter where appropriate.🏁 Scripts executed

70-79: LGTM! Consider clarifying the relationship betweenrenderFunctionandisRenderer.The addition of
renderFunctionandisRendererproperties to theRegisteredComponentinterface is well-implemented and aligns with the PR objective of supporting async server operations. The detailed comments provide clear explanations of their purposes.To further improve clarity, consider adding a note about the relationship between these two properties. For example:
// Note: All renderer functions are render functions, but not all render functions are renderer functions. // A component can have renderFunction: true and isRenderer: false, but not vice versa.This addition would help developers understand the hierarchy and constraints between these two properties.

191-191: Fix typo and improve comment clarityThere's a typo in the comment: "cleanining" should be "cleaning". Also, consider rephrasing the comment for better readability.
Apply this diff to correct the typo and enhance the comment:
-// Promises only supported in node renderer and node renderer takes care of cleanining console history +// Promises are only supported in the Node renderer, which takes care of cleaning console history
