From 5da1e572a1f7d4ab6bc0445eb65a52fa8e7b19d0 Mon Sep 17 00:00:00 2001 From: Krystie Date: Sun, 29 Mar 2026 19:46:41 -0700 Subject: [PATCH] refactor(server): Complete Phase 2.1 - Split monolithic server.js MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MASSIVE REFACTOR: - Created src/app.js (17KB) - Express setup, middleware, routes - Slimmed server.js from 1997 lines → 230 lines (88% reduction!) - Backed up original as server-old.js for reference NEW STRUCTURE: src/ ├── app.js (Express application factory) ├── config/ (paths, site config, constants) ├── context/ (DI container, domain modules) └── utils/ (http, logging, responses, async-handler) STATS: - Old server.js: 1997 lines (monolith) - New server.js: 230 lines (entry point only) - Modular code: 1729 lines across 14 files in src/ - Total reduction: 88% in main file server.js now ONLY handles: - App creation - License loading - HTTP server startup - Feature module initialization - Graceful shutdown All business logic moved to src/ modules. Clean, testable, maintainable.
