npm package: @grackle-ai/web
Description: React web UI for the Grackle multi-agent coordination platform
Latest version: 0.108.0

# @grackle-ai/web

The Grackle web dashboard -- a single-page application for managing remote AI coding agents, environments, tasks, and workspaces. It connects to the Grackle server over WebSocket for real-time state updates and streams agent output as it happens.

## Features

- **Real-time agent streaming** -- watch tool calls, code output, and agent reasoning as they happen, bridged from gRPC through the server's WebSocket layer.
- **Task tree management** -- create, edit, and monitor hierarchical task trees with parent/child relationships, dependency gating, review/approval workflows, and inline findings.
- **DAG visualization** -- interactive dependency graph powered by React Flow, showing task hierarchy and dependency edges at a glance.
- **Environment management** -- add, configure, and monitor Docker, SSH, Local, and Codespace environments from a unified panel.
- **Workspace boards** -- group tasks and sessions around a shared repo and environment; track progress, cost, and session history per workspace.
- **Chat with the orchestrator** -- talk directly to the root agent through a chat interface with full access to every Grackle MCP tool.
- **Findings panel** -- browse categorized discoveries shared across agents within a workspace.
- **Persona management** -- create and configure specialized agent personas with custom runtimes, models, and system prompts.
- **Credential & token management** -- store and manage API keys and provider credentials from the Settings page.
- **10 built-in themes** -- Grackle, Grackle Light, Glassmorphism, Matrix, Neubrutalism, Monokai, Ubuntu, Sandstone, Verdigris, and Primer. Several themes offer light/dark variants. Switch in Settings or follow system preference.
- **Responsive layout** -- sidebar drawer with mobile breakpoints, keyboard shortcuts (Escape to close), and animated page transitions.
- **Setup wizard** -- guided onboarding flow for first-time users.

| Layer | Technology |
|-------|------------|
| Framework | React 19 |

| Markdown | react-markdown + remark-gfm + rehype-prism-plus |
| Testing | Vitest + React Testing Library |
| Shared types | `@grackle-ai/common` (protobuf-generated) |

## Development

```bash
# From the repo root -- install dependencies and build all packages
rush install && rush build

# Start the Vite dev server (hot-reload on port 5173)
cd packages/web
rushx dev
```

The dev server proxies `/ws` requests to `ws://localhost:3000`, so you need a running Grackle server for live data. Start one with:

```bash
# In another terminal
node packages/cli/dist/index.js serve
```

Then open http://localhost:5173.

### Build for production

```bash
rushx build      # TypeScript check + Vite production build → dist/
rushx preview    # Serve the production build locally
```

### Run tests

```bash
rushx test       # Vitest unit tests
```

### Mock mode

Append `?mock` to the URL (e.g., `http://localhost:5173/?mock`) to run the UI with a mock data provider instead of a live server connection. Useful for frontend development without a running backend.
