PR Review: Room → CallSession Refactoring

I've completed a comprehensive review of this large-scale refactoring PR. Here's my detailed analysis:

Todo List:

• Read and understand the refactoring scope
• Review renamed files for consistency
• Check for missed references to old naming
• Evaluate test coverage and updates
• Assess breaking change impact
• Check changeset requirements
• Provide comprehensive feedback

---

Overall Assessment ✅

This is a well-executed large-scale refactoring that successfully replaces "Room" concepts with "CallSession" terminology. The changes are systematic and comprehensive, with good consistency across the codebase.

Code Quality & Best Practices ✅

Positive Aspects:

• Systematic renaming: Files, classes, interfaces, and methods have been consistently renamed
• Maintained functionality: All core functionality appears preserved during the rename
• Proper deprecation: Added @deprecated annotations for backward compatibility (e.g., RoomScreenShare, CallDevice)
• Clean file structure: Removed obsolete files and consolidated interfaces appropriately
• Test coverage: E2E tests have been updated to use new terminology

Architecture Consistency:

• BaseCallSession properly extends the architecture pattern
• CallSessionConnection maintains the same interface contracts
• CallSessionScreenShare and CallSessionDevice follow existing patterns
• Event system preserved with proper event name mappings

Potential Issues & Concerns ⚠️

Minor Issues Found:

1. Typo in variable name packages/client/src/unified/workers/callSegmentWorker.ts:28:

   const segmentRooSessionId = action.payload.room_session_id

   Should be segmentRoomSessionId (missing 'm')

2. Documentation references still mention old API packages/client/src/CallSessionDevice.ts:46-49:

   /**
    * A CallSessionDevice represents a device (such as a microphone or a camera)
    * that is at some point in its lifetime part of a {@link RoomSession}. You can
    * obtain a CallSessionDevice from the {@link RoomSession} methods
    * {@link RoomSession.addCamera}, {@link RoomSession.addMicrophone}, and
    * {@link RoomSession.addDevice}.
    */

   References to RoomSession should be updated to CallSession.

3. Inconsistent interface naming packages/client/src/utils/interfaces/call.ts:246:

   /** Whether the screen share object should automatically join the room */
   autoJoin?: boolean
   /** Audio constraints to use when joining the room. Default: `true`. */
   audio?: MediaStreamConstraints['audio']

   Comments still reference "room" instead of "call session".

Room vs Call Session Event Considerations:

• room.left, room.updated, room.joined events are still used for backward compatibility
• This is appropriate as these are internal event names that maintain API consistency
• The public API correctly uses CallSession terminology

Performance Considerations ✅

• No performance regressions expected
• File consolidation reduces bundle size (removed 1000+ lines of duplicate code)
• Event handling architecture remains unchanged

Security Concerns ✅

• No security issues identified
• Authentication and session management patterns unchanged
• No exposure of sensitive data

Breaking Change Assessment 🚨

This is correctly marked as a breaking change. Impact analysis:

Public API Changes:

• RoomSession → CallSession class name changes
• Import path changes for consumers
• Method signature consistency maintained
• Event names preserved for backward compatibility

Migration Path:

• Clear deprecation warnings provided
• Type aliases maintain backward compatibility temporarily
• Documentation comments need updates

Test Coverage Assessment ✅

Well-Updated Areas:

• E2E tests: Comprehensive updates across all test files
• Unit tests: Core functionality tests updated
• Integration tests: CallSession integration properly tested

Test Quality:

• Tests properly validate new class names and imports
• Event handling tests cover the refactored components
• Screen sharing and device management tests updated

Changeset Requirements ⚠️

Issue: The changeset-bot indicates no changeset is present, but this IS a breaking change that requires one.

Recommendation: Add a changeset with:

---
"@signalwire/client": major
---

BREAKING: Rename Room concepts to CallSession

- RoomSession → CallSession
- VideoRoomSession → CallSession  
- RoomScreenShare → CallSessionScreenShare
- Related interfaces and types updated

Recommendations

High Priority Fixes:

1. Add required changeset for this breaking change
2. Fix the typo: segmentRooSessionId → segmentRoomSessionId
3. Update documentation: Fix JSDoc references to old RoomSession API

Medium Priority:

1. Update interface comments: Change "room" to "call session" in type definitions
2. Consider migration guide: Document the breaking changes for users

Low Priority:

1. Event naming consistency: Consider whether internal events should also be renamed in future versions

Conclusion

This is a high-quality refactoring that successfully modernizes the terminology while maintaining functionality. The main issues are minor documentation inconsistencies and the missing changeset. The architectural decisions are sound and the execution is thorough.

Recommendation: ✅ Approve with minor fixes - Address the changeset requirement and fix the small issues identified above.
