A CARE plugin that embeds an Excalidraw whiteboard into CARE, letting clinicians sketch and annotate diagrams directly within patient workflows.

Built as a CARE micro-frontend using Module Federation. The plugin exposes a manifest that CARE loads at runtime from a remote remoteEntry.js.

• React 19 + TypeScript
• Vite 6 with @originjs/vite-plugin-federation
• @excalidraw/excalidraw
• Tailwind CSS v4
• raviger (routing) and react-i18next (localization) — shared with the CARE host

Clone the repository and install dependencies:

git clone https://github.com/ohcnetwork/care_excalidraw_fe
cd care_excalidraw_fe
npm install

Start the dev server (builds the federated bundle in watch mode and serves a preview):

npm run dev

The plugin is served at http://localhost:4173, with the federation entry at http://localhost:4173/assets/remoteEntry.js.

Make sure you have CARE running locally, then:

1. Open the CARE Admin Dashboard (usually http://localhost:4000/admin).

2. Go to the Apps section and click Add New Config.

3. Add a slug and set the following as the Meta:

   {
     "url": "http://localhost:4173/assets/remoteEntry.js",
     "name": "care_excalidraw"
   }

4. Save the configuration and reload CARE.

The name must match the federation name in vite.config.ts (care_excalidraw). Changing one without the other will prevent CARE from resolving the remote module.

This plugin is published in the CARE Apps Registry as care_excalidraw. When installing through the App Store, CARE computes the meta.url from the configured App base URL as ${appBaseUrl}/assets/remoteEntry.js, so you only need to provide the base URL (e.g. http://localhost:4173 for local development or https://care-excalidraw.pages.dev for production).
