From c48a0c5e3ba9c8dfa712f5a90b1ca9556b0cb474 Mon Sep 17 00:00:00 2001 From: MythEclipse Date: Mon, 1 Jun 2026 21:44:29 +0700 Subject: [PATCH] refactor: split monolith into 3 microservices (frontend, backend, discord-gateway) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Extract services into services/{frontend,backend,discord-gateway} - Create packages/shared/ for shared logger, errors, utils, types - Setup Modular MVC pattern in backend (controller→service→repository) - Setup event-driven architecture in discord-gateway with Redis pub/sub - Move Docker files to infra/docker/ with per-service Dockerfiles - Update docker-compose.yml to use Traefik-only routing (no port exposes) - Update GitHub Actions deploy workflow for multi-service matrix build - Fix all import paths and resolve type errors across all services - All 3 services pass tsc --noEmit clean Co-Authored-By: Claude Opus 4.8 --- .github/workflows/deploy-docker.yml | 92 +-

Architecture Patterns + +### Modular MVC Structure +Each module follows Controller-Service-Repository pattern: +- **Controller**: Discord event listeners (messageCapture, aiAnalyzer, voiceController) +- **Service**: Business logic (messageStore, llmModerationClient, recorder) +- **Repository**: Data access (messageStore, voiceRecordingRepo) + +### Event-Driven Design +- **Redis Pub/Sub**: All events published to Redis channels +- **Event Channels**: + - `discord:message:created` — New message captured + - `discord:message:updated` — Message edited + - `discord:message:deleted` — Message deleted + - `discord:message:analyzed` — AI analysis complete + - `discord:attachment:created` — Attachment detected + - `discord:attachment:uploaded` — Attachment uploaded to storage + - `discord:voice:started` — Voice recording started + - `discord:voice:stopped` — Voice recording stopped + - `discord:voice:uploaded` — Voice segment uploaded + - `discord:analysis:queue_status` — Analysis queue status update + +### Shared Infrastructure +- **Config**: Zod-validated environment variables +- **Logger**: Winston logger with context support +- **Database**: Drizzle ORM with PostgreSQL +- **Errors**: Custom error classes with codes and status codes +- **Utils**: Retry logic with exponential backoff + +### No HTTP Server +- Discord Gateway service is **event-driven only** +- No Express, WebSocket, or HTTP routes +- All communication via Redis pub/sub +- Backend service consumes events and serves HTTP API + +## Initialization Flow + +1. Load environment config (Zod validation) +2. Initialize database connection +3. Run pending migrations +4. Create Discord client with optimized cache settings +5. Initialize Redis event broadcaster +6. Register Discord event listeners (messageCapture, aiAnalyzer) +7. Login to Discord +8.

Exit process + +## Dependencies + +**Core Discord**: +- discord.js-selfbot-v13 +- @discordjs/voice +- @discordjs/opus + +**Audio Processing**: +- prism-media (Opus encoding/decoding) +- opusscript (Opus fallback) +- sharp (Image resizing) + +**Data & Config**: +- drizzle-orm (ORM) +- pg (PostgreSQL driver) +- zod (Config validation) +- ioredis (Redis client) + +**Logging & Utilities**: +- winston (Structured logging) +- p-retry (Retry logic) +- p-limit (Concurrency limiting) +- piscina (Worker pool) + +## Event Flow Example + +### Message Capture Flow +1. Discord emits `messageCreate` event +2. `messageCapture.ts` listener receives event +3. Extract metadata (user, channel, content, timestamp) +4. `messageStore.ts` inserts into database +5. `eventBroadcaster.messageCreated()` publishes to Redis +6. Backend service subscribes to `discord:message:created` channel +7. Backend processes and stores in its own database + +### Voice Recording Flow +1. `voiceController.connect()` joins voice channel +2. `recorder.ts` subscribes to user audio streams +3. For each speaking user: + - Create audio stream subscription + - Decode Opus packets to PCM + - Rotate OGG segments (5s default) + - Collect user metadata +4. On silence (3s): + - Finalize segment + - Create metadata JSON + - Upload segment to storage + - Publish `discord:voice:uploaded` event +5. Backend service receives event and indexes recording + +## No Breaking Changes + +- Original `src/` remains untouched for now +- Discord Gateway is a **new service** in `services/discord-gateway/` +- Can run alongside existing monolith during transition +- Backend service will consume Redis events +- Frontend continues to use Backend HTTP API diff --git a/services/discord-gateway/MODULE_STRUCTURE.md b/services/discord-gateway/MODULE_STRUCTURE.md new file mode 100644 index 0000000..536a8aa --- /dev/null +++ b/services/discord-gateway/MODULE_STRUCTURE.md @@ -0,0 +1,408 @@ +# Discord Gateway Service -
