Provides a runtime and compile time switch for ivy including `ApplicationRef.bootstrapModule`. This is done by naming the symbols such that `ngcc` (angular Compatibility compiler) can rename symbols in such a way that running `ngcc` command will switch the `@angular/core` module from `legacy` to `ivy` mode. This is done as follows: ``` const someToken__PRE_NGCC__ = ‘legacy mode’; const someToken__POST_NGCC__ = ‘ivy mode’; export someSymbol = someToken__PRE_NGCC__; ``` The `ngcc` will search for any token which ends with `__PRE_NGCC__` and replace it with `__POST_NGCC__`. This allows the `@angular/core` package to be rewritten to ivy mode post `ngcc` execution. PR Close #25238
Sanitization
This folder contains sanitization related code.
History
It used to be that sanitization related code used to be in @angular/platform-browser
since it is platform related. While this is true, in practice the compiler schema is permanently tied to the DOM and hence the fact that sanitizer could in theory be replaced is not used in practice.
In order to better support tree shaking we need to be able to refer to the sanitization functions from the Ivy code. For this reason the code has been moved into the @angular/core
.
