**cereale/min** — the library flattened into one minified ES module,
25.5 KB / 8.6 KB gzipped, for import maps, <script type="module">, Deno
and Workers. Built from dist/esm/index.js, so the decorator lowering and
the ES2025 target are tsc's; esbuild only flattens and minifies.
It is an addition rather than a replacement, and the measurement is the
reason. Bundled through esbuild the flat and per-module builds land within
2 bytes of each other; through rollup + terser the flat one is 165 bytes
smaller; unused decorators tree-shake out of both. With the size argument a
wash, per-module stays the default import for the one thing it does better
— readable stack traces without source maps. (My first pass at that
measurement reported "shaken" for every symbol because both rollup builds
had failed and grep was reading missing files as absence. The check now
asserts the bundle is non-empty and that a *used* symbol is present, so it
can tell a real result from a broken harness.)
**FRAMEWORKS.md** — a recipe per framework, each one run before it was
written, with the versions and date verified against.
Angular works, which was not obvious: the CLI scaffolds
experimentalDecorators: true, but ngtsc erases @Component and @Injectable
into static properties rather than leaning on TypeScript's decorator emit.
Flip the flag and both systems coexist. Verified with ngc on Angular 21.2
with strictTemplates — templates still type-check and a wrong cereale rule
is still TS1240 inside the Angular build.
Next.js cannot work inline, structurally: it derives both the SWC parser's
decorator support and the transform mode from the one flag, so on gives
legacy emit and off makes @ a syntax error. NestJS cannot either — its DI
needs design:type from emitDecoratorMetadata.
Both have the same answer: keep the cereale classes in a package compiled
by tsc and import the built output. Verified inside a program with BOTH
legacy flags on, alongside @Injectable() — mapping and validation work, and
the compile-time guarantee still holds where the rules are written.
Also verified: Bun 1.3 needs no configuration, and a real Vite 8 build with
the plugin works where the same build without it silently leaves decorator
syntax in the bundle.
Version 0.4.0: cereale/min is a new public entry point, and cutting a minor
keeps the existing v0.3.0 tag meaningful instead of force-moving it onto a
commit it was never cut from.
