UI performance: a typical page now transfers ~290 KB instead of ~4.8 MB, and almost nothing on repeat visits. Every page previously pulled 4,847 KB of vendor JS/CSS across 31 files, uncompressed and uncacheable. Four independent fixes:
- Static assets are now cacheable. They were served with no validator, so browsers re-downloaded everything on every navigation. Assets now carry an
ETag(scoped to the build version) andCache-Control: max-age=3600, and conditional requests get a304— repeat navigations transfer a few hundred bytes. The short max-age plus a version-scoped ETag means an upgrade still picks up new assets rather than pinning stale ones. - Responses are compressed (gzip/brotli, negotiated per request). Worth ~82% on the remaining assets and on the large HTML report tables.
- Unused libraries removed. jQuery UI (252 KB, loaded only for an AdminLTE shim that guards against a clash which cannot occur once jQuery UI is gone), InputMask (100 KB) and Moment.js (60 KB) were on every page and referenced by nothing. The external Ionicons CDN stylesheet is also gone — no
ion-*icon is used, and dropping it removes a third-party request per page load (which also blocked page render on air-gapped installs). - Heavy optional libraries are now opt-in per page.
jszip/pdfmake/vfs_fonts(2.2 MB) load only on the five pages with Excel/PDF table buttons; Chart.js only on the dashboard and the two live report pages; Select2 and Duallistbox only on the form pages that use those widgets. Beyond bandwidth this removes the JS parse cost on every other page.
Net: a baseline page goes from 4,847 KB / 31 files to 1,954 KB / 19 files, or ~290 KB on the wire once compressed — then near-zero on subsequent navigations.
