# Hermes Web UI

Web dashboard for [Hermes Agent](https://github.com/EKKOLearnAI/hermes-agent) — chat interaction, session management, scheduled jobs, and log viewing.

## Tech Stack

- **Vue 3** — Composition API + `<script setup>`
- **TypeScript**
- **Vite** — Build tool
- **Naive UI** — Component library
- **Pinia** — State management
- **Vue Router** — Routing (Hash mode)
- **Koa 2** — BFF server (API proxy, file upload, session management)
- **SCSS** — Style preprocessor
- **markdown-it** + **highlight.js** — Markdown rendering and code highlighting

## Install and Run

```bash
npm install -g hermes-web-ui
hermes-web-ui start
```

Open http://localhost:8648

### CLI Commands

| Command | Description |
|---------|-------------|
| `hermes-web-ui start` | Start in background (daemon mode) |
| `hermes-web-ui start --port 9000` | Start on custom port |
| `hermes-web-ui stop` | Stop background process |
| `hermes-web-ui restart` | Restart background process |
| `hermes-web-ui status` | Check if running |
| `hermes-web-ui` | Run in foreground (for debugging) |

### Auto Configuration

On startup, the BFF server automatically checks `~/.hermes/config.yaml` and ensures `platforms.api_server.enabled` is set to `true`. If modified, it backs up the original to `config.yaml.bak` and restarts the gateway.

## Development

```bash
git clone https://github.com/EKKOLearnAI/hermes-web-ui.git
cd hermes-web-ui
npm install
npm run dev
```

This starts:
- Frontend: http://localhost:5173
- BFF Server: http://localhost:8648 (proxies to Hermes on 8642)

### Build

```bash
npm run build
```

Outputs to `dist/` (frontend + compiled BFF server).

## Architecture

```
Browser → BFF (Koa, :8648) → Hermes API (:8642)
                ↓
           Hermes CLI (sessions, logs, version)
```

The BFF layer handles:
- API proxy to Hermes (with header forwarding)
- SSE streaming passthrough
- File upload to temp directory
- Session CRUD via Hermes CLI
- Log file reading and parsing
- Static file serving (SPA fallback)
