HealthChat desktop variant
===========================

This directory is the `--cfgdir` / build config for HealthChat desktop builds:

  config.json   Element Web runtime config baked into webapp.asar. Mirrors
                apps/web/config.json (HealthChat homeserver, theme, branding) and
                loads the HealthChat plugin:
                  - "modules": ["/modules/healthchat-module.js"]
                  - "ch.healthchat.elements_base_url": "/webapp/modules/elements"
  build.json    electron-builder variant (appId, productName "HealthChat", protocols).

Why the paths differ from web
-----------------------------
The desktop app serves the webapp from `vector://vector/webapp/`, so root-relative
paths need a `/webapp` prefix:

  - The `modules` array is rewritten automatically by apps/desktop/src/electron-main.ts
    (`/modules/x` -> `/webapp/modules/x`), so it stays as `/modules/healthchat-module.js`.
  - `ch.healthchat.elements_base_url` is NOT auto-rewritten (the elements bundle is loaded
    by a <script> tag the plugin injects, not by the module loader), so it is set explicitly
    to `/webapp/modules/elements` here. On web it is `/modules/elements`.

The plugin artifacts must live inside the asar at `modules/healthchat-module.js` and
`modules/elements/healthchat-elements.js`.

Building locally
----------------
  # 1. Build the element-plugin (from the healthchat-workspace checkout) and stage it:
  (cd ../healthchat-workspace/element-plugin && npm ci && npm run build)
  (cd ../healthchat-workspace/element-plugin/module && npm ci && npm run build)
  mkdir -p plugin-dist/elements
  cp ../healthchat-workspace/element-plugin/module/dist/healthchat-module.js plugin-dist/healthchat-module.js
  cp ../healthchat-workspace/element-plugin/dist/elements/browser/main.js plugin-dist/elements/healthchat-elements.js

  # 2. Build the fork webapp with the plugin injected:
  ./apps/desktop/scripts/build-healthchat-webapp.sh

  # 3. Pack and run:
  cp apps/desktop/element.io/healthchat/config.json apps/desktop/webapp/config.json
  pnpm --dir apps/desktop run asar-webapp
  pnpm --dir apps/desktop start

CI
--
.github/workflows/build-healthchat-desktop.yaml builds the plugin + webapp artifact and
feeds it into build_desktop_prepare.yaml (`config: element.io/healthchat`,
`webapp-artifact: healthchat-webapp`) and build_desktop_linux.yaml.

Open items before a production release
--------------------------------------
  - api_base_url: confirm the production API origin in config.json (currently assumed
    https://healthchat.ch). On desktop this MUST be absolute (vector:// origin can't reach
    a relative /api).
  - Fork vs upstream shell: build_desktop_prepare.yaml / build_desktop_linux.yaml check out
    element-hq/element-web (upstream). The webapp + variant are HealthChat's, but the Electron
    shell (electron-main, icons) is upstream. Point those workflows at this fork to fully brand
    the shell, and to guarantee the `/modules` -> `/webapp/modules` rewrite is present.
  - macOS/Windows: need signing/notarization secrets; add the macos/windows reusable workflows
    once configured.
  - Deploy target: the upstream deploy job pushes to packages.element.io / Cloudflare R2 — wire
    up a HealthChat distribution target instead.
