ollie-webui

Browser-based front-end for ollie. A Preact single-page application that talks to ollie-httpgw over REST. Provides session management, a chat interface with markdown rendering, and theme switching.

Prerequisites

• Either olliesrv or ollied running (provides the D-Bus org.ollie.SessionManager interface)
• ollie-httpgw running (HTTP → D-Bus gateway)

Build

npm install
npm run build

Output: dist/ (static files).

Development

Vite dev server with hot reload and API proxy:

npm run dev
# Open http://localhost:5173

The proxy forwards /sessions, /backends, /agents, and /openapi.json to localhost:8011 (httpgw default with -listen :8011, or adjust vite.config.ts).

Serve (production)

dist/ is a static site. Serve with any HTTP server and proxy API paths to httpgw:

server {
    listen 3000;
    root /path/to/ollie/webui/dist;
    index index.html;

    location / { try_files $uri /index.html; }

    location ~ ^/(sessions|backends|agents|openapi\.json)(/|$) {
        proxy_pass http://localhost:8011;
    }
}

Features

• Session list sidebar with state, backend, model, and cwd
• Create, rename, and kill sessions
• Send prompts; updates via 250ms poll
• Stop a running agent turn
• Markdown rendering of assistant responses (via marked + mermaid + KaTeX)
• Two built-in themes: midnight (dark) and acme (Plan 9-inspired light); persisted to localStorage

Stack

• Preact (UI)
