ISR

over full SSR

Marketing pages changed weekly, not per request. Incremental regeneration kept them effectively static, fast first byte, no rebuild pipeline to babysit, while the storefront stayed server-rendered where freshness actually mattered.

A provider-agnostic payment interface

over Integrating whichever gateway got approved

Gateway approval was pending and the launch date was not. One shared contract with each provider behind it meant the checkout was finished before the business decision was. That turned out to matter more than expected: we ran Razorpay first, then Paytm, then Cashfree, and each move was a route switch rather than a reintegration.

Polling with explicit cleanup

over trusting the redirect callback

Payment confirmation can land late, or the user can close the tab mid-flow. I polled for terminal status and tore the interval down on unmount and on resolution, so no orphaned timers, and no order stuck reading "processing" because a callback never arrived.

react-hook-form

over controlled component state

The waitlist and pre-booking forms had dynamic fields and cross-field validation. Controlled inputs re-rendered the whole form on every keystroke; uncontrolled refs kept large forms responsive and put validation in one schema instead of scattered handlers.
