# Monlet Web
Dashboard for Monlet. Monitoring pages are read-only; agent admission and blacklist controls can mutate server state.
## Stack
- Next.js 16 (App Router)
- React 19
- TypeScript
- Tailwind CSS v4
- Typed API client generated from `api/openapi.yaml`
## Commands
```sh
cd web
npm_config_cache=../.cache/npm npm install
npm_config_cache=../.cache/npm npm run dev
```
Build / lint / typecheck / smoke:
```sh
npm_config_cache=../.cache/npm npm run build
npm_config_cache=../.cache/npm npm run lint
npm_config_cache=../.cache/npm npm run typecheck
npm_config_cache=../.cache/npm npm run smoke
```
Do not install Node packages globally. Project dependencies live in `web/node_modules`; npm cache lives under repository `.cache/npm`.
## Environment
| Var | Default | Purpose |
|---|---|---|
| `MONLET_API_BASE_URL` | `http://127.0.0.1:8000` | Server base URL (server-side fetch) |
| `MONLET_API_TOKEN` | _(none)_ | Bearer token sent to server |
| `MONLET_WEB_TIME_ZONE` | `UTC` | IANA timezone used to render timestamps |
| `MONLET_WEB_AUTH_USERNAME` | _(none)_ | Optional local web login username |
| `MONLET_WEB_AUTH_PASSWORD` | _(none)_ | Optional local web login password |
| `MONLET_WEB_SESSION_SECRET` | _(none)_ | Secret used to sign the web session cookie; required with local web login; at least 32 bytes |
| `MONLET_WEB_SESSION_TTL_SEC` | `604800` | Local web session lifetime |
| `MONLET_WEB_TRUST_PROXY_AUTH` | `false` | Trust `X-Forwarded-User` from an upstream auth proxy |
The API token never reaches the browser — all server calls happen in Server Components / route handlers. Agent admission actions are blocked unless local web login is configured or trusted proxy auth is enabled.
Production deployments should rate-limit `/login` at the reverse proxy. The app applies constant-time credential checks and a small fixed delay on failed login attempts, but it is not a full auth gateway.
The timezone switcher stores the selected mode in browser cookies, so each operator keeps their own default/browser/UTC preference.
## Pages
- `/` — redirects to `/agents`
- `/agents` — agent list
- `/agents/blacklist` — blocked agent keys
- `/agents/[id]` — agent detail
- `/checks` — current check states
- `/incidents` — incident list
- `/events` — events query
- `/outbox` — notification outbox
## API client
Types are generated from `../api/openapi.yaml` into `src/lib/api-types.ts` via `npm run gen:api`.
