Built with --stats-json and read the esbuild metafile instead of guessing.
@angular/compiler was 495,831 bytes of a 1.5 MB main chunk - the JIT
compiler, in an AOT production build, 33% of everything an anonymous
visitor downloads.
src/main.ts imported it deliberately, with a comment explaining that
@marketplaces/auth shipped plain tsc output carrying no Ivy metadata, so
Angular JIT-compiled its classes at runtime and bootstrap threw without
it.
That comment was stale. The package is 0.2.0, built with ng-packagr,
module: dist/fesm2022/marketplaces-auth.mjs - proper Angular Package
Format, partial-compiled (ɵɵngDeclareInjectable), linked at consumer
build time. Nothing needs JIT.
Verified against the production bundle served statically, not just a
green build: the failure mode this guarded was a runtime throw, so a
successful compile proves nothing. Angular 22.0.8 bootstrapped, the
router resolved /ru, and the app rendered its own "server unavailable"
screen - meaning DI, HttpClient and the full interceptor chain ran. That
chain injects AuthService from @marketplaces/auth, the exact class the
old comment named. Zero JIT or compiler errors; the only console output
was the expected 404s from having no backend behind a static server.
Initial bundle 1.55 MB -> 1.04 MB raw, 323.58 kB -> 215.45 kB transfer.
Budget ratchet lowered 1.6MB -> 1.1MB, which is now also what stops the
import being re-added.
Next lever, deliberately not taken here: i18n/ru.ts is 290 kB, eager,
while en/hy are already lazy. TranslateService has the loader plumbing
and languageGuard already awaits a preload, so it is mechanically small -
but it adds a round-trip before first paint for the majority language,
which is a product tradeoff, not a cleanup. Roughly a 750 kB bundle once
someone decides.
256 tests pass.
