* Page-loading strategy. |
| 7 |
* |
| 8 |
* Pages >1500 lines are split into separate chunks via React.lazy so they |
| 9 |
* land in the JS bundle on demand instead of inflating the initial paint. |
| 10 |
* Vite picks these up automatically as separate output files — operators |
| 11 |
* who never visit the Whatsapp tab never download its ~80KB of code. |
| 12 |
* |
| 13 |
* Pages that ship eagerly: |
| 14 |
* - Dashboard: the default landing route, almost always rendered first |
| 15 |
* - Smaller list pages (Trips, Bookings, Customers, etc.) where the |
| 16 |
* lazy-chunk overhead (extra HTTP round-trip on first nav) outweighs |
| 17 |
* the bytes saved on initial paint |
| 18 |
* |
| 19 |
* Pages that ship lazily (in line-count order, biggest savings first): |
| 20 |
* - TripForm (9.6k loc) |
| 21 |
* - Settings (8.6k loc) |
| 22 |
* - Team (3.5k loc) |
| 23 |
* - Reports (3.1k loc) |
| 24 |
* - DiscountForm (2.7k loc) |
| 25 |
* - Itinerary (2.7k loc) |
| 26 |
* - RecurringRuleForm (2.6k loc) |
| 27 |
* - Whatsapp (2.6k loc) |
| 28 |
* - ChannelManager (2.5k loc) |
| 29 |
* - Webhooks (2.5k loc) |
| 30 |
* - TripConsentForm (2.1k loc) |
| 31 |
* - BookingForm (1.8k loc) |
| 32 |
* - DynamicPricing (1.8k loc) |
| 33 |
* - AvailabilityForm (1.7k loc) |
| 34 |
* - AiAssistant (1.6k loc) |
| 35 |
* - AbandonedRecovery (1.6k loc) |
| 36 |
* - WhiteLabel (1.6k loc) |
| 37 |
* - DynamicPricingRuleForm (1.5k loc) |
| 38 |
* - ViewBooking (1.5k loc) |
| 39 |
* |
| 40 |
* If you add a new heavy page, lazy-import it here too; cheap to add and |
| 41 |
* the only thing to remember is that lazy components must be rendered |
| 42 |
* inside a <Suspense> boundary (we wrap the whole renderPage() output). |
