Summary

This PR improves type safety across the Reactotron codebase by replacing any types in the CommandMap interface with specific, well-defined TypeScript interfaces. All payload types are now consolidated in reactotron-core-contract for consistency and reusability.

Changes Made

1. New Type Definitions in reactotron-core-contract

Created dedicated type definition files for command payloads:

• apiResponse.ts - ApiResponsePayload for HTTP request/response data
• asyncStorage.ts - AsyncStorageMutationPayload for storage mutations
• benchmark.ts - BenchmarkReportPayload for performance benchmarks
• clientIntro.ts - ClientIntroPayload for client connection info
• display.ts - DisplayPayload for custom display events
• image.ts - ImagePayload for image data with metadata
• sagaTaskComplete.ts - SagaTaskCompletePayload and SagaTaskCompleteChild for Redux-saga tasks
• customCommand.ts - CustomCommandRegisterPayload and CustomCommandUnregisterPayload
• repl.ts - ReplLsResponsePayload and ReplExecuteResponsePayload

2. Updated CommandMap Interface

Replaced all any types with specific payload types:

// Before
[CommandType.ApiResponse]: any
[CommandType.Display]: any
// ...

// After
[CommandType.ApiResponse]: ApiResponsePayload
[CommandType.Display]: DisplayPayload
// ...

3. Updated reactotron-core-client

• Imported and used new payload types from reactotron-core-contract
• Updated DisplayConfig to extend DisplayPayload
• Fixed type assertions for name and id fields where needed
• Updated plugins (api-response, benchmark, image, repl) to use contract types
• Removed local type definitions that are now in the contract

4. Updated reactotron-core-ui

Removed duplicate type definitions in UI command components and imported types from reactotron-core-contract:

• ApiResponseCommand
• AsyncStorageMutationCommand
• BenchmarkReportCommand
• ClientIntroCommand
• DisplayCommand
• ImageCommand
• SagaTaskCompleteCommand

5. Documentation

Updated reactotron-core-contract/README.md with:

• Comprehensive usage examples for clients and plugins
• Complete command type reference tables
• Guide for plugin authors
• Examples showing how to use CommandType and payload types

Notes

• Some fields remain typed as any where appropriate (e.g., saga middleware dynamic data, storage values, eval results)
• All existing functionality is preserved - this is purely a type safety improvement
• No breaking changes to the public API
