Move Pro features from core gem to Pro gem #1854
Conversation
This PR moves all Pro-specific features from lib/react_on_rails/pro/ to the react_on_rails_pro gem, ensuring complete separation between MIT and Pro licensed code. Key Changes: - Move immediate_hydration config from core to Pro gem (default: true in Pro) - Refactor helper methods to use data enhancement pattern - Core gem collects script data, Pro gem enhances it if loaded - Delete lib/react_on_rails/pro/ directory entirely - Update RenderOptions to retrieve immediate_hydration from Pro config - Add comprehensive tests for immediate_hydration option - Update LICENSE.md to reflect that lib/react_on_rails/ is now 100% MIT - Update MONOREPO_MERGER_PLAN.md with new Phase 5 Benefits: - Clean separation: Core gem is 100% MIT licensed - No HTML parsing needed for Pro enhancements - Better architecture: Core gem doesn't know about Pro internals - Backward compatible: Functionality unchanged Technical Implementation: - Core gem's generate_component_script() and generate_store_script() collect script attributes as data structures before HTML generation - If Pro gem is loaded, ReactOnRailsPro::Helper.enhance_*_script_data() adds immediate hydration attributes and scripts - Core gem then generates final HTML from the enhanced data - RenderOptions.immediate_hydration uses retrieve_react_on_rails_pro_config_value_for() 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

256-256: Critical: Update to use Pro configuration.Line 256 references
ReactOnRails.configuration.immediate_hydration, but this configuration option was removed from the core gem in this PR (seelib/react_on_rails/configuration.rb). This will cause aNoMethodErrorat runtime.Apply this fix to retrieve from Pro configuration:
- immediate_hydration = ReactOnRails.configuration.immediate_hydration if immediate_hydration.nil? + if immediate_hydration.nil? + immediate_hydration = if ReactOnRails::Utils.react_on_rails_pro? + ReactOnRailsPro.configuration.immediate_hydration + else + false + end + endThis aligns with how
RenderOptions#immediate_hydrationretrieves the value (line 99 oflib/react_on_rails/react_component/render_options.rb).
🧹 Nitpick comments (2)
react_on_rails_pro/lib/react_on_rails_pro/helper.rb (2)
29-47: Consider copyingscript_attrsto avoid mutating input parameters.The method mutates the input
script_attrshash (line 32) and then returns it. This creates confusion because the caller retains a reference to the now-modified object. While the mutation may be intentional given the method name "enhance", the pattern of mutating and returning the same object is unclear.Consider this refactor for clarity:
def self.enhance_component_script_data(script_attrs:, _script_content:, render_options:) + enhanced_attrs = script_attrs.dup if render_options.immediate_hydration # Add data attribute for immediate hydration - script_attrs["data-immediate-hydration"] = true + enhanced_attrs["data-immediate-hydration"] = true # Add immediate invocation script escaped_dom_id = escape_javascript(render_options.dom_id) immediate_script = content_tag(:script, %( typeof ReactOnRails === 'object' && ReactOnRails.reactOnRailsComponentLoaded('#{escaped_dom_id}'); ).html_safe) return { - script_attrs: script_attrs, + script_attrs: enhanced_attrs, additional_scripts: [immediate_script] } end - { script_attrs: script_attrs, additional_scripts: [] } + { script_attrs: enhanced_attrs, additional_scripts: [] } endAlternatively, if mutation is intended, consider adding a bang suffix (
enhance_component_script_data!) or documenting the behavior.Note: The XSS protection using
escape_javascriptbefore interpolation, followed bycontent_tagandhtml_safe, is correct. The defensivetypeofcheck in the generated JavaScript is also good practice.
54-72: Consider copyingscript_attrsto avoid mutating input parameters.This method has the same input mutation pattern as
enhance_component_script_data. Thescript_attrshash is modified in place (line 57) and then returned, which can be confusing for callers.Apply the same refactor pattern as suggested for
enhance_component_script_data:def self.enhance_store_script_data(script_attrs:, _script_content:, redux_store_data:) + enhanced_attrs = script_attrs.dup if redux_store_data[:immediate_hydration] # Add data attribute for immediate hydration - script_attrs["data-immediate-hydration"] = true + enhanced_attrs["data-immediate-hydration"] = true # Add immediate invocation script escaped_store_name = escape_javascript(redux_store_data[:store_name]) immediate_script = content_tag(:script, %( typeof ReactOnRails === 'object' && ReactOnRails.reactOnRailsStoreLoaded('#{escaped_store_name}'); ).html_safe) return { - script_attrs: script_attrs, + script_attrs: enhanced_attrs, additional_scripts: [immediate_script] } end - { script_attrs: script_attrs, additional_scripts: [] } + { script_attrs: enhanced_attrs, additional_scripts: [] } endNote: The security implementation and defensive programming patterns are consistent and correct.

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

react_on_rails_pro/lib/react_on_rails_pro.rb (1)
12-12: LGTM! Load-time dependency added correctly.The require statement properly loads the new Pro helper module that provides enhancement hooks for component and store script data.
LICENSE.md (1)
14-14: LGTM! License scope correctly updated.The entire
lib/react_on_rails/directory is now MIT licensed, reflecting the successful separation of Pro features into thereact_on_rails_pro/directory.lib/react_on_rails/configuration.rb (2)
73-75: LGTM! Configuration attributes correctly updated.The
immediate_hydrationoption has been properly removed from the public API, aligning with the migration to Pro gem configuration.
90-92: LGTM! Initializer signature updated correctly.The
immediate_hydrationparameter has been removed from the initializer, completing the removal from core configuration.lib/react_on_rails/react_component/render_options.rb (3)
17-17: LGTM! Simplified options assignment.Direct assignment removes dependency on Pro utilities, aligning with the separation of Pro code.
20-20: LGTM! Public API surface correctly narrowed.The
explicitly_disabled_pro_optionsattribute has been removed from the public interface as part of Pro feature separation.
98-100: LGTM! Immediate hydration correctly retrieves from Pro configuration.The method now uses
retrieve_react_on_rails_pro_config_value_forto fetch the value from Pro gem configuration when available, returning nil when Pro is not installed.spec/react_on_rails/react_component/render_options_spec.rb (1)
167-223: LGTM! Comprehensive test coverage for Pro feature.The test suite thoroughly covers:
- Explicit
immediate_hydrationoption values (true/false)- Default behavior when Pro gem is installed (reads from Pro config)
- Default behavior when Pro gem is not installed (returns nil)
- Proper mocking of Pro module and configuration
The use of
stub_constandreceive_message_chainappropriately simulates Pro gem presence without requiring actual Pro installation.react_on_rails_pro/lib/react_on_rails_pro/configuration.rb (1)
33-33: LGTM! Pro configuration correctly implements immediate_hydration.The implementation is complete and follows the established pattern:
- Constant
DEFAULT_IMMEDIATE_HYDRATION = trueprovides sensible default- Public accessor enables runtime configuration
- Initialize parameter and assignment properly handle the value
- Integration into configuration hash at line 33 enables proper initialization
The default value of
truealigns with Pro feature expectations where immediate hydration is enabled by default.Also applies to: 57-57, 66-66, 76-76, 99-99
lib/react_on_rails/helper.rb (2)
794-825: LGTM! Well-structured data-enhancement pattern.The
generate_component_scriptmethod implements a clean separation of concerns:
- Core builds base script attributes and content
- Pro gem enhances data if available (via
ReactOnRailsPro::Helper.enhance_component_script_data)- Core generates final HTML without parsing
This pattern avoids HTML manipulation and provides clear extension points for Pro features.
827-852: LGTM! Consistent implementation for store scripts.The
generate_store_scriptmethod follows the same data-enhancement pattern asgenerate_component_script, ensuring consistency and maintainability. The Pro enhancement hook allows immediate hydration features to be added when the Pro gem is present.spec/dummy/spec/helpers/react_on_rails_helper_spec.rb (1)
29-56: LGTM! Robust test mocking for Pro integration.The updated mock setup effectively simulates Pro gem behavior:
ReactOnRailsPro.configuration.immediate_hydrationreturns trueReactOnRailsPro::Helper.enhance_component_script_datainjects immediate hydration attributes and scripts when enabledReactOnRailsPro::Helper.enhance_store_script_dataprovides similar enhancement for storesThis approach is superior to the previous direct configuration manipulation because:
- Tests are isolated from global configuration state
- Pro behavior is explicitly mocked without requiring Pro installation
- Tests can easily verify different Pro scenarios
- Aligns with the new architecture where Pro features are handled by Pro gem
The mock implementations correctly replicate the expected Pro enhancement behavior shown in
react_on_rails_pro/lib/react_on_rails_pro/helper.rb.react_on_rails_pro/lib/react_on_rails_pro/helper.rb (1)
17-22: LGTM! Appropriate use of ActionView helpers as module methods.The use of
extendto addTagHelperandJavaScriptHelperas class methods is correct for this pattern where methods are called asReactOnRailsPro::Helper.enhance_component_script_data(...). The helpers used (content_tag,escape_javascript) are stateless utilities that work correctly outside of view rendering context.
| #### PR #5: Move Pro Features from Core Gem to Pro Gem | ||
|
|
||
| **Branch:** `move-pro-features-to-pro-gem` | ||
|
|
||
| **Objectives:** | ||
|
|
||
| - Move all Pro features from `lib/react_on_rails/pro/` to Pro gem | ||
| - Delete `lib/react_on_rails/pro/` directory entirely | ||
| - Ensure core gem is 100% MIT licensed with zero Pro code | ||
|
|
||
| **Tasks:** | ||
|
|
||
| - [x] Move `immediate_hydration` config from core gem to Pro gem (default: true in Pro) | ||
| - [x] Refactor `RenderOptions` to remove Pro utilities | ||
| - [x] Refactor helper methods (`generate_component_script`, `generate_store_script`) to use data enhancement pattern | ||
| - [x] Create Pro helper module in Pro gem with enhancement methods | ||
| - [x] Delete `lib/react_on_rails/pro/` directory entirely | ||
| - [x] Update LICENSE.md to remove `lib/react_on_rails/pro/` reference | ||
| - [x] Update tests in both gems | ||
|
|
||
| **Implementation Details:** | ||
|
|
||
| The `immediate_hydration` feature was the only Pro feature in the core gem. The refactoring uses a data enhancement pattern: | ||
|
|
||
| 1. Core gem collects script attributes/content as data structures (not HTML) | ||
| 2. If Pro gem loaded, it modifies the data (adds attributes, adds extra scripts) | ||
| 3. Core gem generates final HTML from the (possibly enhanced) data | ||
|
|
||
| **Benefits:** | ||
|
|
||
| - ✅ Clean separation: Core gem = 100% MIT, Pro gem = 100% Pro license | ||
| - ✅ No HTML parsing needed | ||
| - ✅ No Pro warning badge needed (can't enable Pro features without Pro gem) | ||
| - ✅ Better architecture: Core gem doesn't know about Pro internals | ||
|
|
||
| **License Compliance:** | ||
|
|
||
| - [x] **CRITICAL: Update LICENSE.md:** | ||
|
|
||
| ```md | ||
| ## MIT License applies to: | ||
|
|
||
| - `lib/react_on_rails/` (entire directory) | ||
| - `packages/react-on-rails/` (entire package) | ||
|
|
||
| ## React on Rails Pro License applies to: | ||
|
|
||
| - `packages/react-on-rails-pro/` (entire package) | ||
| - `react_on_rails_pro/` (entire directory) | ||
| ``` | ||
|
|
||
| - [x] Verify no Pro code remains in core gem directories | ||
|
|
||
| **Success Criteria:** ✅ All CI checks pass + `lib/react_on_rails/pro/` deleted + Core gem is 100% MIT licensed | ||
|
|
||
| **Estimated Duration:** 2-3 days | ||
|
|
||
| **Risk Level:** Medium (requires careful refactoring of helper methods) | ||
|
|
||
| **Developer Notes:** | ||
|
|
||
| - The core gem now calls `ReactOnRailsPro::Helper.enhance_component_script_data` and `ReactOnRailsPro::Helper.enhance_store_script_data` if Pro gem is loaded | ||
| - The `immediate_hydration` method in `RenderOptions` now uses `retrieve_react_on_rails_pro_config_value_for(:immediate_hydration)` | ||
| - Tests have been updated to mock Pro gem functionality | ||
|

Restore the missing phase heading before PR #5.
After introducing this new PR, the document skips a “Phase 5” heading and jumps straight to “Phase 6,” which now contradicts the stated 8-phase plan. Please add the appropriate phase heading (e.g., ### Phase 5: ...) above this block so the numbering stays consistent.
🤖 Prompt for AI Agents
In docs/MONOREPO_MERGER_PLAN.md around lines 407 to 472, the document jumps from
Phase 4 to Phase 6 because the Phase 5 heading is missing; insert an appropriate
Phase 5 heading (for example: "### Phase 5: Move Pro features into Pro gem /
Core cleanup") immediately above the "PR #5: Move Pro Features from Core Gem to
Pro Gem" block so the numbering is consistent with the 8-phase plan and the
section is clearly labeled.
Since the Pro warning badge functionality has been removed (users can't enable Pro features without Pro gem installed), all tests related to the warning badge are now obsolete and have been removed. Tests removed: - react_component: 'with Pro license warning' context (4 test cases) - react_component_hash: 'with Pro license warning' context (2 test cases) - redux_store: 'with Pro license warning' context (3 test cases) These tests were checking for warning badges and log messages that no longer exist in the codebase.

29-56: Consider extracting mock logic to helper methods.The mock implementations for
enhance_component_script_dataandenhance_store_script_dataare comprehensive and test the integration well. However, the 25+ lines of conditional logic make thebeforeblock dense.Consider extracting the mock implementations to helper methods:
def mock_enhance_component_script_data(args) return { script_attrs: args[:script_attrs], additional_scripts: [] } unless args[:render_options].immediate_hydration dom_id = args[:render_options].dom_id script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ "ReactOnRails.reactOnRailsComponentLoaded('#{dom_id}');\n </script>" { script_attrs: args[:script_attrs].merge("data-immediate-hydration" => true), additional_scripts: [script_tag] } end def mock_enhance_store_script_data(args) return { script_attrs: args[:script_attrs], additional_scripts: [] } unless args[:redux_store_data][:immediate_hydration] store_name = args[:redux_store_data][:store_name] script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ "ReactOnRails.reactOnRailsStoreLoaded('#{store_name}');\n </script>" { script_attrs: args[:script_attrs].merge("data-immediate-hydration" => true), additional_scripts: [script_tag] } endThen in the

dom_idandstore_namewithout escaping. While this is acceptable in tests with controlled input, the real Pro implementation usesescape_javascriptas noted in the PR objectives. This discrepancy doesn't affect test correctness but means the mocks don't exactly mirror production escaping behavior.

Learning: In React on Rails, the force_load feature includes both explicit `data-force-load="true"` usage and the ability to hydrate components during the page loading state (`document.readyState === 'loading'`). Both capabilities require a Pro license, so the condition `!railsContext.rorPro && (isComponentForceLoaded || document.readyState === 'loading')` correctly gates both scenarios.

25-27: LGTM! Pro gem availability mocks are clear.The mocks correctly simulate the Pro gem being present and licensed, which is appropriate for testing the integration between core and Pro functionality.
Moved immediate_hydration configuration from ReactOnRails initializers to ReactOnRailsPro initializers in dummy apps, reflecting the migration of this Pro feature from the core gem to the Pro gem. Changes: - Removed config.immediate_hydration from spec/dummy core initializer - Added config.immediate_hydration = true to Pro initializers in: - react_on_rails_pro/spec/dummy - react_on_rails_pro/spec/execjs-compatible-dummy Note: Explicitly set to true to match Pro gem's default and demonstrate the Pro feature is enabled in Pro dummy apps.
Code Review: PR #1854 - Move Pro features from core gem to Pro gemSummaryThis PR successfully achieves its goal of completely separating MIT-licensed core functionality from Pro-licensed features. The architecture is clean, well-documented, and maintains backward compatibility. ✅ Strengths1. Excellent Architecture PatternThe data enhancement pattern is brilliant:

).html_safe)Recommendation: While
Risk Level: Medium - Minor: Code Quality Issues1. Inconsistent Hash ReturnsLocation: The methods have an early return when immediate_hydration is true, then a separate return at the end. While functional, this could be cleaner: # Current
if render_options.immediate_hydration
# ... setup ...
return { script_attrs: script_attrs, additional_scripts: [immediate_script] }
end
{ script_attrs: script_attrs, additional_scripts: [] }
# Suggested
additional_scripts = if render_options.immediate_hydration
# ... setup ...
[immediate_script]
else

32-44: LGTM! Consider escape_javascript for improved test accuracy.The mock correctly implements the data-enhancement pattern, checking
immediate_hydrationfrom render_options and conditionally adding the hydration script and attribute.Optional refinement: Line 36 directly interpolates
dom_idinto a JavaScript string. While this works for tests, the actual Pro helper usesescape_javascriptper the AI summary. Consider using it here to make the mock more accurate and serve as better documentation:- script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ - "ReactOnRails.reactOnRailsComponentLoaded('#{dom_id}');\n </script>" + escaped_dom_id = ActionController::Base.helpers.escape_javascript(dom_id) + script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ + "ReactOnRails.reactOnRailsComponentLoaded('#{escaped_dom_id}');\n </script>"
45-57: LGTM! Consider escape_javascript for consistency.The store script enhancement mock correctly mirrors the component script logic, adapted for the store data structure.
Optional refinement: Similar to the component script mock, line 49 directly interpolates
store_name. For consistency and accuracy with the actual Pro helper implementation:- script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ - "ReactOnRails.reactOnRailsStoreLoaded('#{store_name}');\n </script>" + escaped_store_name = ActionController::Base.helpers.escape_javascript(store_name) + script_tag = "<script>\n typeof ReactOnRails === 'object' && " \ + "ReactOnRails.reactOnRailsStoreLoaded('#{escaped_store_name}');\n </script>"
426-446: Consider adding a test for redux_store with immediate_hydration: false.The component tests cover both
immediate_hydration: trueandimmediate_hydration: falsecases (lines 389-399), but the store tests only cover thetruecase. Adding a test forredux_storewithimmediate_hydration: falsewould ensure comprehensive coverage of the Pro gem enhancement behavior for stores.Example test to add after line 446:
context "with 'immediate_hydration' == false" do subject(:store) { redux_store("reduxStore", props: props, immediate_hydration: false) } let(:react_store_script_no_immediate_hydration) do '<script type="application/json" data-js-react-on-rails-store="reduxStore">' \ '{"name":"My Test Name"}' \ "</script>" end it "does not include data-immediate-hydration attribute" do expect(store).not_to include('data-immediate-hydration="true"') end it "does not include the immediate hydration script" do expect(store).not_to include("ReactOnRails.reactOnRailsStoreLoaded") end end

30-35: Safer Pro configuration stubCurrent stub replaces the full config object with a Struct exposing only immediate_hydration. If core later reads another Pro config key, specs will break. Prefer stubbing the chain to just the needed value.
- stub_const("ReactOnRailsPro", Module.new do - def self.configuration - @configuration ||= Struct.new(:immediate_hydration).new(true) - end - end) + stub_const("ReactOnRailsPro", Module.new) + allow(ReactOnRailsPro).to receive_message_chain(:configuration, :immediate_hydration).and_return(true)
50-62: Add assertions for store “loaded” script and false caseYou already validate the store tag’s data-immediate-hydration attribute. Add coverage for:
- Presence of the injected “ReactOnRails.reactOnRailsStoreLoaded(...)” script when immediate_hydration: true
- Absence of both the attribute and script when immediate_hydration: false
Example additions in this spec:

Learning: RSC support validation in React on Rails Pro is handled through a chain of validations:
1. Pro version check in `run_stream_inside_fiber`
2. RSC support check during pack generation via `ReactOnRailsPro.configuration.enable_rsc_support`
3. RSC support validation during component registration
This makes additional validation in the helper methods unnecessary.

Return HTML-safe buffers from the Pro helper stub.
The real ReactOnRailsPro::Helper builds these scripts with content_tag(...).html_safe, so downstream code treats them as trusted. Here we’re returning plain strings, which Rails will escape when safe-joining (<script> instead of <script>), meaning the spec would still pass even if the helper accidentally stopped emitting executable tags. Please mark these stubs as HTML safe (or build them via content_tag) so the test faithfully exercises the production contract.

In spec/dummy/spec/helpers/react_on_rails_helper_spec.rb around lines 37 to 59,
the helper stubs return plain strings for script tags which Rails will escape in
views; update the stub to return HTML-safe buffers by calling .html_safe on the
script_tag strings (or build them via content_tag(...).html_safe) for both
enhance_component_script_data and enhance_store_script_data so
additional_scripts contains HTML-safe content that mirrors the real
ReactOnRailsPro::Helper contract.
Pull Request Review: Move Pro Features from Core Gem to Pro GemOverall AssessmentThis is a well-architected and thoroughly executed refactoring. The PR successfully achieves complete license separation between MIT and Pro-licensed code using a clean data enhancement pattern. The implementation is solid with good test coverage. Code Quality & ArchitectureExcellent Design PatternsData Enhancement Pattern - Clean separation of concerns where core gem builds data structures and Pro gem enhances them. No HTML parsing needed. The enhance_component_script_data and enhance_store_script_data methods are well-designed and extensible. Configuration Retrieval - The retrieve_react_on_rails_pro_config_value_for method (render_options.rb:164-170) is elegant, falls back gracefully when Pro gem not loaded, and maintains backward compatibility. Potential Issues & Concerns1. Security: XSS Prevention (MEDIUM PRIORITY)Location: react_on_rails_pro/lib/react_on_rails_pro/helper.rb:35-38, 60-63 The inline JavaScript generation uses escape_javascript correctly, but add explicit tests for XSS scenarios with malicious dom_id values (e.g., containing </script> tags or quotes). 2. Inconsistent String Formatting (LOW PRIORITY)Location: react_on_rails_pro/lib/react_on_rails_pro/helper.rb:36-38 Consider using heredocs instead of %(...) for multi-line JavaScript strings for better readability. 3. Missing Validation (MEDIUM PRIORITY)Location: react_on_rails_pro/lib/react_on_rails_pro/helper.rb:29-46, 54-71 The methods don't validate input structure. Consider adding defensive checks for nil values and type validation. 4. Unused Parameter (INFORMATIONAL)The _script_content parameter is intentionally unused. Consider adding a comment explaining it's reserved for future use. Performance ConsiderationsPositive:
Minor: Array concatenation in helper.rb:824 creates temporary arrays. Consider: [main_script, *additional_scripts].join("\n").html_safe Security ConcernsAlready Addressed:

Potential Issues & Suggestions1. Hash Mutation (Minor) - In lib/react_on_rails/helper.rb:818-819, the Pro helper returns a mutated reference to the original script_attrs hash. While this works, it is slightly implicit. Current approach is fine since the hash is not used after enhancement. 2. Error Handling (Low Priority) - If ReactOnRailsPro::Helper.enhance_component_script_data raises an exception, it will bubble up and potentially break rendering. Consider adding graceful fallback if Pro gem failures are expected to be recoverable. Current fail-fast approach may be desirable. 3. Test Coverage Gap (Minor) - Consider adding edge case tests for when Pro gem is available but returns malformed data or enhancement raises an exception. 4. Performance (Informational) - The ReactOnRails::Utils.react_on_rails_pro? check is already memoized in utils.rb:233, so performance impact is minimal. Code Quality Checklist
