The metrics server binds METRICS_PORT (code default 9090; this host runs it on 4018 — 4016 is occupied by another process). Docs said 4016 in three places, which is not what the service does.

# Discord Gateway
|
|
|
|
Event-driven selfbot service: captures Discord events, runs LLM moderation,
|
|
publishes everything to Redis for the backend to consume.
|
|
|
|
> Architecture, invariants and the AI pipeline are documented in
|
|
> **`ARCHITECTURE.md`** — that file is the source of truth. This README only
|
|
> covers how to run it.
|
|
|
|
## Commands
|
|
|
|
```bash
|
|
pnpm install
|
|
pnpm typecheck # tsc --noEmit
|
|
pnpm lint # biome check --diagnostic-level=error .
|
|
pnpm test # vitest run (138 tests)
|
|
pnpm build # tsc — CI/prod builds run this inside nix, which also
|
|
# runs scripts/fix-imports.mjs to rewrite @/ aliases and
|
|
# extensionless imports for Node ESM
|
|
pnpm dev # tsx watch src/index.ts
|
|
pnpm start # node dist/index.js
|
|
```
|
|
|
|
Deployment is CI-only: `nix build .#discord-gateway` → Attic cache → systemd
|
|
restart on the VPS. Do not build/hand-copy the artifact.
|
|
|
|
## Layout
|
|
|
|
```

|
```
|
|
|
|
Dependency direction is one-way: `index.ts` → `app/` → `modules/` → `shared/`.
|
|
Callers outside a module import its `index.ts` facade, never an internal file.
|
|
|
|
## Testing
|
|
|
|
Vitest, tests in `tests/`. Config supplies dummy env vars so the suite runs
|
|
without live Postgres/Redis/Qdrant; external services are mocked. `llmE2e.test.ts`
|
|
is skipped by default and needs real credentials (`pnpm test:e2e:live`).
