Refactor: Split src/index.ts into focused modules#2
Merged
Conversation
Add comprehensive plan to split the 648-line src/index.ts file into 6 focused modules: - src/types.ts - Type definitions and interfaces - src/handlers/mcp-handlers.ts - Core MCP protocol handling - src/session/sse-session.ts - SSE session management - src/routes/mcp-routes.ts - HTTP route handlers - src/decorators/mcp-decorators.ts - Fastify decorators - src/index.ts (refactored) - Main plugin orchestration Plan includes detailed implementation steps and maintains backward compatibility. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Auto-fix all ESLint style issues: - Add missing newlines at end of files - Remove trailing spaces - Fix spacing and formatting 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
The refactoring introduced a bug where SSE event strings used double backslashes (\\n) instead of actual newlines (\n), breaking the SSE format and causing tests to hang waiting for properly formatted events. Fixed in: - src/session/sse-session.ts: replayMessagesFromEventId and sendSSEMessage - src/routes/mcp-routes.ts: SSE event generation and heartbeat messages All tests now pass without timeouts. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
The refactoring is complete, so the planning document is no longer needed. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Break down the large handleRequest function by extracting each switch case into its own focused function: - handleInitialize() - MCP initialization - handlePing() - Ping requests - handleToolsList() - List available tools - handleResourcesList() - List available resources - handlePromptsList() - List available prompts - handleToolsCall() - Execute tool with parameters - handleResourcesRead() - Read resource content - handlePromptsGet() - Get prompt with arguments Benefits: - Improved readability and maintainability - Each handler is now independently testable - Better separation of concerns - Easier to debug and modify individual handlers - Cleaner main handleRequest function Added HandlerDependencies type to reduce repetition and improve type safety. All tests pass, functionality preserved. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…ify plugins Convert the registration functions to proper Fastify plugins following Fastify's plugin architecture: - src/decorators/mcp-decorators.ts: Now exports a Fastify plugin with proper typing (MCPDecoratorsOptions) and uses fastify-plugin wrapper - src/routes/mcp-routes.ts: Now exports a Fastify plugin with proper typing (MCPRoutesOptions) and uses fastify-plugin wrapper - src/index.ts: Updated to register plugins using app.register() instead of direct function calls Benefits: - Better separation of concerns with proper plugin boundaries - Improved type safety with explicit option interfaces - Follows Fastify's recommended plugin architecture - Enables better plugin lifecycle management - Makes plugins independently testable and reusable All tests pass, functionality preserved. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
