serverRenderRSCReactComponent function looks good.
The function performs server-side rendering for React components and includes error handling and stream processing.
Reminder: Add unit tests for serverRenderRSCReactComponent.
Ensure that unit tests are added to cover the new server-side rendering functionality.
Do you want me to generate the unit testing code or open a GitHub issue to track this task?

118-120: Consider adding configuration fallback for consistency.For consistency with other options like
stream?, consider adding a configuration fallback using theretrieve_configuration_value_forpattern. This would allow setting a default RSC behavior in the global configuration.Here's a suggested implementation:
def rsc? - options[:rsc?] + retrieve_configuration_value_for(:rsc?) end
118-120: Add documentation for the RSC feature.Since this is part of adding React Server Components support, it would be helpful to add documentation explaining:
- The purpose of the RSC option
- How it interacts with other rendering options (especially
stream?)- Any requirements or constraints when using RSC
Add RDoc documentation above the method:
+# Returns whether React Server Components (RSC) rendering is enabled. +# @return [Boolean] true if RSC rendering is enabled, false otherwise def rsc? options[:rsc?] endnode_package/src/types/index.ts (1)
174-174: Add JSDoc documentation and consider RSC-specific typesWhile the method signature is correct, consider these improvements:
Add JSDoc documentation explaining:
- The RSC-specific behavior and constraints
- How it differs from

Review the use of canary versions in dependencies
The addition of react-server-dom-webpack and use of canary versions for React packages raises several concerns:
- Using canary versions in production could lead to instability
- All React-related packages should be pinned to the same version
- The peerDependencies need updating to reflect RSC requirements
Let's verify the React version requirements for RSC support:
Suggested updates:
- Document why canary versions are needed
- Update peerDependencies to reflect minimum React version needed for RSC
- Add a warning in the README about the experimental nature of RSC support
Would you like me to help draft the documentation updates?
5-10: Verify the exports configuration and file paths
The exports configuration needs attention in several areas:
- The nested structure under "." might cause compatibility issues with some bundlers
- The export paths need verification
Let's verify the export paths and suggest improvements:
Consider restructuring the exports to be more explicit:
"exports": {
- ".": {
- "rsc-server": "./node_package/lib/ReactOnRailsRSC.js",
- "default": "./node_package/lib/ReactOnRails.js"
- }

Enhance RSC method implementation and documentation
The new RSC method implementation needs improvements in several areas:
- Documentation should explain:
- The purpose of RSC rendering
- When to use this vs regular server rendering
- What an RSC bundle is and how to configure it
- The error message could be more informative about how to resolve the issue
- The eslint-disable comment should be removed and the options parameter should be properly typed or used
Consider this improved implementation:
/**

+ * This method is only available in the RSC-specific bundle and provides streaming support
+ * for React Server Components.

🛠️ Refactor suggestion
Specify a more precise type instead of any for newBundleConfig.
Using any defeats the purpose of TypeScript's type safety. Specifying a more precise type enhances code reliability and maintainability.
Apply this diff to specify a more accurate type:
-const newBundleConfig: { [key: string]: any } = {};
+const newBundleConfig: { [key: string]: typeof bundleConfig[keyof typeof bundleConfig] } = {};This ensures that newBundleConfig has the same value types as the original bundleConfig. Adjust the type as needed based on the actual structure of the config.

🛠️ Refactor suggestion
Avoid assigning AsyncLocalStorage to globalThis; consider alternative approaches.
Assigning to globalThis.AsyncLocalStorage can pollute the global namespace and may lead to conflicts or unintended side effects. Additionally, using an asynchronous IIFE ((async () => { ... })()) for this purpose might introduce race conditions since other parts of the code might access AsyncLocalStorage before it's available.
Consider importing AsyncLocalStorage synchronously where needed without modifying globalThis. For example:
- (async () => {
- try {
- // @ts-expect-error AsyncLocalStorage is not in the node types
- globalThis.AsyncLocalStorage = (await import('node:async_hooks')).AsyncLocalStorage;
- } catch (e) {
- console.log('AsyncLocalStorage not found');
- }
- })();
+ try {
+ // @ts-expect-error AsyncLocalStorage is not in the node types
+ const { AsyncLocalStorage } = require('node:async_hooks');
+ } catch (e) {
+ console.log('AsyncLocalStorage not found');
+ }This approach avoids modifying the global scope and ensures AsyncLocalStorage is available synchronously.

59-65: Consider RSC-specific evaluation pathWhile combining RSC with streaming makes sense, consider if RSC needs additional specific handling:
- RSC might require different error boundaries
- The evaluation context might need RSC-specific setup
- Performance monitoring might need to distinguish between RSC and regular streaming
Consider splitting the condition and adding RSC-specific handling:
- result = if render_options.stream? || render_options.rsc? + result = if render_options.rsc? + js_evaluator.eval_rsc_js(js_code, render_options) + elsif render_options.stream? js_evaluator.eval_streaming_js(js_code, render_options) else js_evaluator.eval_js(js_code, render_options) end

I'd got the other way and ask if you want to include the error stack (at least for development/test).
There was a problem hiding this comment.
@alexeyr-ci, that's a great suggestion. Including the error stack in development and test environments would provide more detailed debugging information. Here's an updated approach:
const isDevOrTest = process.env.NODE_ENV === 'development' || process.env.NODE_ENV === 'test';
const errorMessage = isDevOrTest ? `Error: ${e.stack}` : 'An error occurred while rendering the component';
renderResult = stringToStream(errorMessage);This way, the full error stack is included in non-production environments, aiding in debugging during development and testing.

💡 Codebase verification
🛠️ Refactor suggestion
RSC bundle configuration should follow existing pattern for server bundle
The review suggestion is valid. Based on the configuration class implementation:
- The RSC bundle should follow the same configuration pattern as
server_bundle_js_file, which is already a configurable attribute. - The configuration class needs to be updated to include
rsc_bundle_js_fileas a new configuration option. - Documentation is indeed sparse, with only a brief mention of React Server Components in the README.
Specific changes needed:
- Add
rsc_bundle_js_fileto the Configuration class attributes - Add it to the default configuration in
self.configuration - Update the
ensure_webpack_generated_files_existsmethod to include the RSC bundle file - Add proper documentation about RSC bundle configuration and usage
🔗 Analysis chain
Add configuration support and documentation for RSC bundle
The RSC bundle implementation needs attention in two areas:
- The bundle name is hardcoded. As noted in the TODO, this should be configurable.
- Documentation about the RSC bundle's purpose and usage is missing.
Consider adding configuration support like this:
def self.rsc_bundle_js_file_path
return @rsc_bundle_path if @rsc_bundle_path && !Rails.env.development?
- # TODO: make it configurable
- bundle_name = "rsc-bundle.js"
+ bundle_name = ReactOnRails.configuration.rsc_bundle_js_file || "rsc-bundle.js"
@rsc_bundle_path = bundle_js_file_path(bundle_name)
endAlso, please add documentation explaining:
- The purpose of the RSC bundle
- When and how it's used
- Configuration options
Let me gather more information about the configuration setup to provide a comprehensive verification.
Let me check the configuration class implementation to see the existing configuration pattern.

364-371: Verify the impact of removing component-specific pack loading
The change from component-specific packs to always loading "client-bundle" could affect:
- Initial page load performance
- Bundle size optimization
- Development mode debugging
✅ Verification successful
Based on the examination of the codebase, particularly the webpack configuration and packs generator implementation, I can now provide a final response:
Component-specific pack loading removal is part of automated bundle generation
The change from component-specific packs to a single client bundle is intentional and safe because:
- The codebase has implemented an automated pack generation system (PacksGenerator) that handles component bundling efficiently
- Components are automatically registered and included in the client bundle through the
ReactOnRails.register()mechanism - The webpack configuration (
clientWebpackConfig.js) is properly set up to handle the consolidated bundle approach
The performance impact is mitigated because:
- The packs generator automatically handles component registration and bundling
- The system supports both common and client-specific components with proper separation
- Bundle optimization is handled at the webpack configuration level

Implement error handling for RSC streams
The TODO comment indicates that error handling for RSC streams is not yet implemented. This is critical for production reliability as unhandled errors in server-side rendering could lead to silent failures or degraded user experience.
Consider implementing error handling similar to the existing streaming error handling logic above.
Would you like help implementing the error handling logic for RSC streams? I can provide a solution that follows the existing patterns in the codebase.

Why is this needed instead of importing it elsewhere as normal? When looking for information on this I actually found https://news.ycombinator.com/item?id=35509650
You recently broke Next.js with AsyncLocalStorage by putting it in globalThis and breaking any runtime that's not Vercel's.
Could we run into similar problems?
Instead of ts-expect-error, better to augment globalThis: https://stackoverflow.com/questions/59459312/using-globalthis-in-typescript/69429093#69429093

I'd got the other way and ask if you want to include the error stack (at least for development/test).
