Hermes Web UI

Web dashboard for Hermes Agent — chat interaction, session management, scheduled jobs, platform channel configuration, 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)
• vue-i18n — Internationalization (Chinese / English)
• 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

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

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

npm run build

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

Features

Chat

• Async Run + SSE event streaming via BFF proxy
• Session management via Hermes CLI
• Multi-session switching with message history
• Session grouping by source (Telegram, Discord, Slack, etc.) with collapsible accordion
• Session rename and deletion
• Markdown rendering with syntax highlighting and code copy
• Tool call detail expansion (arguments / result)
• File upload support (saved to temp, path passed to API)
• Model selector — automatically discovers available models from ~/.hermes/auth.json credential pool
• Global model switching (updates ~/.hermes/config.yaml)
• Per-session model display (badge in chat header and session list)

Platform Channels

• Unified channel configuration page (Telegram, Discord, Slack, WhatsApp, Matrix, Feishu, WeChat, WeCom)
• Credential management — writes to ~/.hermes/.env (matching hermes gateway setup behavior)
• Channel behavior settings — writes to ~/.hermes/config.yaml
• WeChat QR code login — opens QR in browser, polls scan status, auto-saves credentials
• Auto gateway restart after any channel config change
• Per-platform configured/unconfigured status detection

Model Management

• Automatically reads credential pool from ~/.hermes/auth.json
• Fetches available models from each provider endpoint (/v1/models)
• Groups models by provider (e.g. zai, subrouter.ai)
• Add custom OpenAI-compatible providers
• Switching model updates model.provider in config.yaml to bypass env auto-detection
• Error handling: parallel fetching, per-provider timeout, fallback to config.yaml parsing

Settings

• Display settings (streaming, compact mode, reasoning, cost, etc.)
• Agent settings (max turns, timeout, tool enforcement)
• Memory settings (enable/disable, char limits)
• Session reset settings (idle timeout, scheduled reset)
• Privacy settings (PII redaction)
• API server settings

Scheduled Jobs

• Job list view (including paused/disabled jobs)
• Create, edit, pause, resume, and delete jobs
• Trigger immediate job execution
• Cron expression quick presets

Skills & Memory

• Browse and search installed skills
• View skill details and attached files
• User notes and profile management

Logs

• View Hermes agent/gateway/error logs
• Filter by log level, log file, and search keyword
• Structured log parsing with HTTP access log highlighting

Other

• Internationalization — auto-detect browser language, manual toggle between Chinese and English
• Real-time connection status monitoring
• Hermes version display in sidebar
• Auto config check on startup
• Minimalist dark theme
• Session group collapse state persisted across navigation

Architecture

Browser → BFF (Koa, :8648) → Hermes API (:8642)
                ↓
           Hermes CLI (sessions, logs, version)
                ↓
           ~/.hermes/config.yaml  (channel behavior)
           ~/.hermes/.env         (platform credentials)
           Tencent iLink API      (WeChat QR login)

The BFF layer handles:

• API proxy to Hermes (with header forwarding)
• SSE streaming passthrough
• File upload to temp directory
• Session CRUD via Hermes CLI
• Config & credential management (config.yaml + .env)
• WeChat QR code login flow (fetch QR, poll status, save credentials)
• Auto gateway restart on platform config changes
• Model discovery from ~/.hermes/auth.json credential pool
• Skills, memory, and custom provider management
• Log file reading and parsing
• Static file serving (SPA fallback)
