`@angular/platform-server` provides the foundation for rendering an Angular app on the server. In order to achieve that, it uses a server-side DOM implementation (currently [domino][1]). For rendering on the server to work as closely as possible to running the app on the browser, we need to make DOM globals (such as `Element`, `HTMLElement`, etc.), which are normally provided by the browser, available as globals on the server as well. Currently, `@angular/platform-server` achieves this by extending the `global` object with the DOM implementation provided by `domino`. This assignment happens in the [setDomTypes()][2] function, which is [called in a `PLATFORM_INITIALIZER`][3]. While this works in most cases, there are some scenarios where the DOM globals are needed sooner (i.e. before initializing the platform). See, for example, #24551 and #39950 for more details on such issues. This commit provides a way to solve this problem by exposing a side-effect-ful entry-point (`@angular/platform-server/init`), that shims the `global` object with DOM globals. People will be able to import this entry-point in their server-rendered apps before bootstrapping the app (for example, in their `main.server.ts` file). (See also [#39950 (comment)][4].) In a future update, the [`universal` schematics][5] will include such an import by default in newly generated projects.
