The lockfile only contained @rollup/rollup-darwin-arm64 because it was last regenerated on macOS, which trips npm's optional-dependency bug (npm/cli#4828) and breaks 'npm ci' on Linux/Windows runners.
Swap the unmaintained parcel-bundler@1.x for Vite's build API, called
from the same generateAssets hook. Output layout is unchanged
(dist/src/main/main.js + dist/static/index.html + dist/renderer.{js,css})
so no runtime path changes — __dirname-based asset lookup, loadFile, and
packagerConfig.ignore all keep working.
Renderer is built in lib/CJS mode with Node builtins + electron
externalized; a one-line banner aliases exports=module.exports since the
Electron <script> context provides module/require but not a bare exports
global. CSS (98.css + root.css) is now imported from app.tsx so Vite
emits a single renderer.css with fonts inlined.
Drops parcel-bundler and rimraf (vite-build clears dist/ itself).
~800ms full build.
The stylesheets only used Less for variables and nesting, both of which
are now native CSS features supported by Electron 41's bundled Chromium.
- src/less/ -> src/css/, all .less files renamed to .css
- @win-* variables -> :root custom properties + var()
- // comments -> /* */
- Dropped unused @win-silver
- Removed less devDependency and the dead 'less' npm script
(pointed at a non-existent tools/lessc.js)
React 19, Electron 41, TypeScript 6, electron-forge 7.8, plus everything
else to latest. Migrated to React 19 createRoot API, updated for Electron 41
session/window type changes, and adjusted tsconfig for TS 6 deprecations.
Regenerated @electron/packager patch for 18.4.4.
