@paperclipai/plugin-hello-world-example

First-party reference plugin showing the smallest possible UI extension.

What It Demonstrates

• a manifest with a dashboardWidget UI slot
• entrypoints.ui wiring for plugin UI bundles
• a minimal React widget rendered in the Paperclip dashboard
• reading host context (companyId) from PluginWidgetProps
• worker lifecycle hooks (setup, onHealth) for basic runtime observability

API Surface

• This example does not add custom HTTP endpoints.
• The widget is discovered/rendered through host-managed plugin APIs (for example GET /api/plugins/ui-contributions).

Notes

This is intentionally simple and is designed as the quickest "hello world" starting point for UI plugin authors. It is a repo-local example plugin for development, not a plugin that should be assumed to ship in generic production builds.

Local Install (Dev)

From the repo root, build the plugin and install it by local path:

pnpm --filter @paperclipai/plugin-hello-world-example build
pnpm paperclipai plugin install ./packages/plugins/examples/plugin-hello-world-example

Local development notes:

• Build first. The host resolves the worker from the manifest entrypoints.worker (e.g. ./dist/worker.js). Run pnpm build in the plugin directory before installing so the worker file exists.
• Dev-only install path. This local-path install flow assumes a source checkout with this example package present on disk. For deployed installs, publish an npm package instead of relying on the monorepo example path.
• Reinstall after pulling. If you installed a plugin by local path before the server stored package_path, the plugin may show status error (worker not found). Uninstall and install again so the server persists the path and can activate the plugin:
  pnpm paperclipai plugin uninstall paperclip.hello-world-example --force then
  pnpm paperclipai plugin install ./packages/plugins/examples/plugin-hello-world-example.
