Lo que suele suponerse
Modifying .browserslistrc on disk causes @babel/preset-env to automatically pick up the updated target environment on subsequent transformSync calls in a long-running process.
El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.
Contrato
- When .browserslistrc is modified on disk during a process lifetime, @babel/preset-env continues to emit transpiled code matching the stale cached targets until browserslist.clearCaches() is explicitly invoked.
- assert modifying .browserslistrc on disk without clearing caches produces output transpiled against stale cached targets
- assert browserslist.clearCaches() evicts memoized config files and forces @babel/preset-env to re-read updated target definitions
- assert passing explicit in-memory targets option bypasses file configuration caching
