Empty path routes are effectively 'passthrough' routes that do not
appear in the URL. When these exist in the route tree, we do not want to
apply named outlet commands to that tree location. Instead, we skip past
this location in the tree, effectively squashing/removing this
passthrough route from the tree.

The documentation incorrectly stated that the app.module.ts file is generated
when the --standalone flag is used. This is not the case, and the documentation
should accurately reflect the behavior.
Closes#51306
PR Close#51307
An empty runtime is added just to make the local compiled angular files valid to run. A separate PR will implement the runtime in the right way using the deps tracker.
PR Close#51089
A factory generator function called "i0.ɵɵgetComponentDepsFactory" is added to generate a factory function for component dependencies. This function will use the deps tracker to calculate the component's dependencies.
For standalone components the component imports (if exists) will be passed to this function. Alternatively this function can grab the imports directly from the decorate, but such extraaction needs some runtime logic which overlapps with what the trait compiler is doing. So better to pass the imports directly to this function at compile time.
PR Close#51089
In local mode the compiler combines the raw imports and exports and pass them to the injector definition as the imports field. It is not possible to filter out ng modules at compile time though, and it will be done in runtime.
Unit tests also added, and since that was the first time adding tests for local compilation some tweaks had to be made in order to disable diagnostics in local compilation mode in order for tests to run (such situation is also the case in real compilation where we ignore all teh diagnostics basically)

A minor error is present within the documentation. Specifically, in the documentation for the CanActivateFn function, a reference is made to the CanActivateChildFn function. However, it appears that the CanActivateChildFn function is not utilized or referenced elsewhere in the documentation of CanActivateFn.

The current change is done behind a flag which is set to false. So no change in code path took place here. In a followup PR the flag is changed to true which will make the actual change.

For cases when a root component also acts as an anchor node for a ViewContainerRef (for example, when ViewContainerRef is injected in a root component), there is a need to serialize information about the component itself, as well as an LContainer that represents this ViewContainerRef. Effectively, we need to serialize 2 pieces of info: (1) hydration info for the root component itself and (2) hydration info for the ViewContainerRef instance (an LContainer). Each piece of information is included into the hydration data (in the TransferState object) separately, thus we end up with 2 ids. Since we only have 1 root element, we encode both bits of info into a single string: ids are separated by the `|` char (e.g. `10|25`, where `10` is the ngh for a component view and 25 is the `ngh` for a root view which holds LContainer).
Previously, we were only including component-related information, thus all the views in the view container remained dehydrated and duplicated (client-rendered from scratch) on the client.
Resolves#51157.
PR Close#51247
This refactoring adds utility functions to add / remove LView from LContainer.
Those utils are preparation for the control flow and defer work.
Existing code was refactored to use the new utility functions and avoid
any code duplication.

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).

PR Close#51170
This commit updates the logic to drop regular imports when all symbols that it brings can be defer-loaded.
The change ensures that there is no mix of regular and dynamic imports present in a source file.
PR Close#51171
Fixes that if a directive/pipe is used after a nested `defer` block, we weren't tracking it as lazy anymore. This was due to the fact that we were resetting the `isInDeferBlock` to false every time instead of the previous value.
PR Close#51262
Adds validations for the following invalid deferred block structures:
* Duplicated triggers.
* Multiple `minimum` parameters on `placeholder` and `loading` blocks.
* Multiple `after` parameters on `loading` blocks.
PR Close#51262
Stores the `deferred` block triggers as a map instead of an array, because triggers can't be duplicated and because having to search through an array will be inconvenient later on.
I've also added a `DeferredBlock.visitAll` method to deduplicate the logic from the various visitor implementations.

the style attribute.

Refactors ElementAttributes to be an implementation detail of the const

Refactors the attribute extraction phase to create a new temporary op

`ElementAttributes`.

Updates the template pipeline's temporary variables phase to reuse
temporary variables within an expression. The algorithm implemented here
reuses variables more aggressively than TemplateDefinitionBuilder. This
change in behavior is acceptable, as it is unlikely to cause any
failures, and implementing the exact behavior observed in
TemplateDefinitionBuilder would be difficult.
PR Close#51100
In some cases it is not feasible to have the template pipeline produce
the exact same compiled output as the TemplateDefinitionBuilder. This
commit adds support to the testing infrastructure to have different
expected output files for each. This option should be used sparingly, as
we want the output to be as close as possible.
