From a1da2d30cec425aa4a5b896537313be5b6ccdff3 Mon Sep 17 00:00:00 2001 From: Pip Build Date: Mon, 16 Feb 2026 23:25:23 -0500 Subject: [PATCH 01/70] feat: REST API layer for web dashboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add Express HTTP server running alongside the Discord WebSocket client, providing a REST API for the upcoming web dashboard. Endpoints: - GET /api/v1/health — uptime, memory, discord status - GET /api/v1/guilds/:id — guild info via Discord client - GET /api/v1/guilds/:id/config — read config - PATCH /api/v1/guilds/:id/config — update config value - GET /api/v1/guilds/:id/stats — AI stats, message counts from DB - GET /api/v1/guilds/:id/members — paginated member list with roles - GET /api/v1/guilds/:id/moderation — paginated mod cases from DB - POST /api/v1/guilds/:id/actions — bot actions (sendMessage) Middleware: - x-api-secret header authentication (BOT_API_SECRET) - Per-IP rate limiting (in-memory) - CORS restricted to DASHBOARD_URL origin - JSON body parsing, global error handler Structure: - src/api/server.js — Express app, middleware, start/stop - src/api/index.js — router mount - src/api/middleware/auth.js — auth middleware - src/api/middleware/rateLimit.js — rate limiter - src/api/routes/health.js — health endpoint - src/api/routes/guilds.js — guild endpoints Integration: - Starts in src/index.js after Discord login - Graceful shutdown before DB close Tests: 5 test files, all endpoints tested with mocked Discord client and DB pool. 80%+ coverage on all metrics.
