Moving from Pages Router to App Router in production

We finally migrated our main dashboards to the Next.js App Router and Server Components. The performance gains are real. Bundle sizes dropped by thirty percent because most components no longer ship JS to the client. Layout nesting and parallel routes simplified our routing layout significantly. Highly recommend making the switch.

this is huge tbh, pages router code splitting was always a bit clunky compared to RSC. not shipping heavy packages like moment or lodash to the client by default is such a win for TBT and INP. app router definitely standardizes web perf imo.

ikr, shipping zero client-side JS for static branches is underappreciated. RSC handles data fetching at the database edge and streams HTML directly, saving CPU cycles on mobile. pages router felt like we were sending the entire kitchen sink just to render a simple article tbh.
