This commit updates provideClientHydration to automatically enable incremental hydration by default. It also introduces a new withNoIncrementalHydration feature for opting out, adds conflict safety checks, and includes a schematic migration.
This commit adds a utility method to debug why the application has not stabilized after
a set period of time (9 seconds, or `hydrationTimeout-1`).

The zoneless scheduler is always enabled, so if hydration works with zoneless, it works
for all Angular apps. There is no need for detection of custom zone implementations
PR Close#63847
Adds an internal token to detect when both hydration and blocking initial navigation are enabled. Logs a warning during app initialization if this unsupported combination is found, helping developers avoid misconfiguration and potential runtime issues.

Prior to this commit, `hasHttpTransferCacheOptions` was calculated immediately after the `featuresKind` set was declared, which was always defaulted to `false`.
PR Close#60605
Removed two typos in the withHttpTransferCacheOptions function description.
- Corrected spelling of "whether"
- Changed spelling from "a an" to "an"

This commit drops the `@developerPreview` annotation from the `withEventReplay()` function, which effectively makes the Event Replay feature stable.

Angular recently gained a local compilation mode (see commit
345dd6d81a). This is intended to be used
with the TypeScript compiler option isolatedModules, which bans imports
of const enums.
This changes all const enums tagged with @publicApi to regular enums.
Fixes#46240

This commit removes the `@developerPreview` annotation from the `provideClientHydration` function and related symbols, promoting them to stable.
PR Close#52197
This commit removes the `withNoDomReuse` function to minimize public API. The `withNoDomReuse` function used to disable DOM reuse, which is the main feature of the `provideClientHydration()`.
The `withNoDomReuse()` function was in the "developer preview" mode, so the removal happens without prior deprecation.
BREAKING CHANGE:
The `withNoDomReuse()` function was removed from the public API. If you need to disable hydration, you can exclude the `provideClientHydration()` call from provider list in your application (which would disable hydration features for the entire application) or use `ngSkipHydration` attribute to disable hydration for particular components. See this guide for additional information: https://angular.io/guide/hydration#how-to-skip-hydration-for-particular-components.
PR Close#52057
`provideClientHydration()` accepts new `HydrationFeature` : `HttpTransferCacheOptions`.
`withHttpTransferCacheOptions` accepts an option object:
* `includeHeaders` : list of headers entries to keep in the cache with the request
* `filter` a callback to determine if a request should be cached
* `includePostRequests`: to include POST requests in the allowed methods
Implements some of the features requested in #50117

non-destructive hydration expects the DOM tree to have the same structure in both places.
With this commit, the app will throw an error if comments are stripped out by the http server (eg by some CDNs).
fixes#51160
PR Close#51170
Hydration relies on a signal from ZoneJS when it becomes stable inside an application, so that Angular can start serialization process on the server or post-hydration cleanup on the client (to remove DOM nodes that remained unclaimed).
Providing a custom or a "noop" ZoneJS implementation may lead to a different timing of the "stable" event, thus triggering the serialization or the cleanup too early or too late. This is not yet a fully supported configuration.
This commit adds a warning (non-blocking) for those cases.
PR Close#49944
This commit updates the docs for the `withNoDomReuse` function, which lets to opt out of non-destructive hydration.
The docs now mention the need to configure an initial navigation option for the Router to be blocking, i.e.
use `withEnabledBlockingInitialNavigation()` Router feature.
PR Close#49895
This commit adds support by default for HTTP caching when using `provideClientHydration`. Users can opt-out of this behaviour by using the `withoutHttpTransferCache` feature.
```ts
import {
bootstrapApplication,
provideClientHydration,
withNoHttpTransferCache,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration(withNoHttpTransferCache())]
});
```
PR Close#49699
This commit adds the `provideClientHydration` function to the public API. This function can be used to enable the non-destructive Angular hydration.
Important note: the non-destructive hydration feature is in Developer Preview mode, learn more about it at https://angular.io/guide/releases#developer-preview.
Before you can get started with hydration, you must have a server side rendered (SSR) application. Follow the [Angular Universal Guide](https://angular.io/guide/universal) to enable server side rendering first. Once you have SSR working with your application, you can enable hydration by visiting your main app component or module and importing `provideClientHydration` from `@angular/platform-browser`. You'll then add that provider to your app's bootstrapping providers list.
```typescript
import {
bootstrapApplication,
provideClientHydration,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration()]
});
```
Alternatively if you are using NgModules, you would add `provideClientHydration` to your root app module's provider list.
```typescript
import {provideClientHydration} from '@angular/platform-browser';
import {NgModule} from '@angular/core';
@NgModule({
declarations: [RootCmp],
exports: [RootCmp],
bootstrap: [RootCmp],
providers: [provideClientHydration()],
})
export class AppModule {}
```
You can confirm hydration is enabled by opening Developer Tools in your browser and viewing the console. You should see a message that includes hydration-related stats, such as the number of components and nodes hydrated.
