# Dev Server Skill

Centralized management of Next.js dev servers across multiple git worktrees. The daemon handles port allocation, environment variable injection, and log aggregation so that any agent can access dev server logs regardless of who started the server.

## Quick Start

```bash
# Check what's running
node .claude/skills/dev-server/cli.mjs status

# Start a dev server for current worktree
node .claude/skills/dev-server/cli.mjs start

# Start for a specific worktree
node .claude/skills/dev-server/cli.mjs start /path/to/worktree

# View logs
node .claude/skills/dev-server/cli.mjs logs <session-id>

# Stop a session
node .claude/skills/dev-server/cli.mjs stop <session-id>
```

**Checking if server is ready:** After starting, poll the session status to check `ready: true`. The daemon marks sessions ready either via configured health check endpoint or by detecting "Ready" patterns in logs.

## CLI Commands

| Command | Description |
|---------|-------------|
| `status` | Check daemon status and list all sessions |
| `list` | List all dev sessions |
| `start [worktree]` | Start dev server (default: current directory) |
| `logs [session-id]` | Get logs for a session |
| `tail [session-id]` | Tail logs continuously |
| `stop <session-id>` | Stop a session |
| `restart <session-id>` | Restart a session |
| `rgb [subcmd]` | RGB proxy control (`status`\|`start`\|`stop`\|`restart`\|`logs`) |
| `shutdown` | Shutdown the daemon |

## Session Object

Each session includes:

```json
{
  "id": "a1b2c3d4",
  "worktree": "/path/to/worktree",
  "branch": "feature/my-feature",
  "port": 3000,
  "status": "running",
  "ready": true,
  "readyAt": "2024-01-15T10:30:02.000Z",
  "startedAt": "2024-01-15T10:30:00.000Z",
  "url": "http://localhost:3000"
}
```

Status values: `starting`, `running`, `stopped`, `crashed`, `error`

## Log Entries

```json
{
  "index": 42,
  "timestamp": "2024-01-15T10:30:05.123Z",
  "level": "stdout",
  "message": "Ready on http://localhost:3000"
}
```

Log levels: `stdout`, `stderr`, `error`, `warn`, `info`

## Dashboard TUI

Run `node .claude/skills/dev-server/console.mjs` (or `npm run dev:daemon`) for a live terminal dashboard.

| Key | Action |
|-----|--------|
| `1` | Filter: errors (error + warn levels) |
| `2` | Filter: bitdex |
| `3` | Filter: trpc |
| `4` | Filter: api |
| `5` | Filter: prisma |
| `6` | Filter: stdout only |
| `7` | Filter: stderr only |
| `8` | Filter: info (daemon messages) |
| `/` or `f` | Free-text search (type query, Enter to apply) |
| `a` | Show all logs (clear filter) |
| `r` | Restart session |
| `c` | Clear log buffer |
| `x` | Stop session + exit |
| `R` | Toggle RGB proxy (start/stop) |
| `q` | Quit dashboard (server keeps running) |
| `K` | Kill daemon + quit |

Filters toggle on/off. Active filter is highlighted in the footer bar. Search highlights matching text in red.

## RGB Proxy

The daemon can optionally manage the `rgb-proxy` reverse proxy (serves `civitai-dev.{red,green,blue}` against the local dev server).

### Configuration

Edit `.claude/skills/dev-server/.env`:

```env
RGB_PROXY_ENABLED=true            # auto-start proxy when daemon boots
RGB_PROXY_PATH=../rgb-proxy       # path relative to project root
```

Also ensure the main `.env` has `NEXTAUTH_URL=https://civitai-dev.blue` + `SERVER_DOMAIN_*` and hosts file maps the three domains to `127.0.0.1`. See `.claude/skills/rgb-proxy/SKILL.md` for first-time setup.

### Control

```bash
# Start / stop / restart / status / logs via CLI
node .claude/skills/dev-server/cli.mjs rgb start
node .claude/skills/dev-server/cli.mjs rgb status

# Or via pnpm scripts
pnpm dev:rgb          # start proxy (daemon boots if not already running)
pnpm dev:rgb:stop
pnpm dev:rgb:status
```

In the dashboard TUI, press `R` to toggle the proxy.

### Admin / sudo requirement

Redbird binds ports 80 and 443. On Windows the daemon must be launched from an elevated terminal; on macOS/Linux start it with `sudo`. If it fails the daemon surfaces `lastError` via `/rgb` status and in RGB proxy logs.

## Notes

- The daemon starts automatically when you run CLI commands
- Sessions persist until explicitly stopped or the daemon shuts down
- Logs are kept in memory (up to 2000 lines per session)
