This commit adds sanitization for `elementProperty` and `elementAttribute` instructions used in `hostBindings` function, similar to what we already have in the `template` function. Main difference is the fact that for some attributes (like "href" and "src") we can't define which SecurityContext they belong to (URL vs RESOURCE_URL) in Compiler, since information in Directive selector may not be enough to calculate it. In order to resolve the problem, Compiler injects slightly different sanitization function which detects proper Security Context at runtime. PR Close #27939
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
.
