HttpClient is an evolution of the existing Angular HTTP API, which exists
alongside of it in a separate package, @angular/common/http. This structure
ensures that existing codebases can slowly migrate to the new API.
The new API improves significantly on the ergonomics and features of the legacy
API. A partial list of new features includes:
* Typed, synchronous response body access, including support for JSON body types
* JSON is an assumed default and no longer needs to be explicitly parsed
* Interceptors allow middleware logic to be inserted into the pipeline
* Immutable request/response objects
* Progress events for both request upload and response download
* Post-request verification & flush based testing framework
`Object.assign` is not available in all supported browsers and one had to
provide a polyfill. This commit replaces `Object.assign` with the spread
operator (`...`), which TypeScript will transpile to ES5-compatible code.
(#17971)
This commit changes the dynamic version of ngUpgrade to use `UpgradeHelper`,
thus bringing its behavior (wrt upgraded components) much closer to
`upgrade/static`. Fixes/features include:
- Fix template compilation: Now takes place in the correct DOM context, instead
of in a detached node (thus has access to required ancestors etc).
- Fix support for the `$onInit()` lifecycle hook.
- Fix single-slot transclusion (including optional transclusion and fallback
content).
- Add support for multi-slot transclusion (inclusing optional slots and fallback
content).
- Add support for binding required controllers to the directive's controller
(and make the `require` behavior more consistent with AngularJS).
- Add support for pre-/post-linking functions.
(This also ports the fixes from #16627 to the dynamic version.)
Fixes#11044
(#17971)
Although, pre- and post-linking functions are correctly called during directive
linking, directives with `link.post` would throw an error. Interestingly, having
`link.pre` only or defining `link: fn` (which is an alias for `link.post: fn`)
would not throw.
This commit removes this check and allows directives with pre- and/or
post-linking functions to work.
Previously, only simple, single-slot transclusion worked on upgraded components.
This commit fixes/adds support for the following:
- Multi-slot transclusion.
- Using fallback content when no transclusion content is provided.
- Destroy unused scope (when using fallback content).
Fixes#13271
- /deep/ is deprecated and being removed from Chrome
- >>> is semantically invalid in a stylesheet
- sass will no longer support either in any version of sass
-> use ::ng-deep in emulated shadow DOM mode
Because the deep combinator is deprecated in the CSS spec,
`/deep/`, `>>>` and `::ng-deep` are also deprecated in emulated shadow DOM mode
and will be removed in the future.

Destructuring of the form:
function foo({a, b}: {a?, b?} = {})
breaks strictNullChecks, due to the TypeScript bug https://github.com/microsoft/typescript/issues/10078.
This change eliminates usage of destructuring in function argument lists in cases where it would leak
into the public API .d.ts.
toString() from DefaultKeyValueDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
With 4.2, we introduced the min and max validator directives. This was actually a breaking change because their selectors could include custom value accessors using the min/max properties for their own purposes.
For now, we are rolling back the change by removing the exports. At the least, we should wait to add them until a major version. In the meantime, we will have further discussion about what the best solution is going forward for all validator directives.
Closes#17491.
----
PR #17551 tried to roll this back, but did not remove the dead code. This failed internal tests that were checking that all declared directives were used.
This PR rolls back the original PR and commit the same as #17551 while also removing the dead code.

This puts the behavior introduced in 573b8611bc behind the new flag
`alwaysCompileGeneratedCode` to not break users that might have relied
on this behavior.
This PR fixes an issue where `query(':enter')` will only collect elements up until it an element that is found that isn't apart of the `:enter` query.
Closes#17440
Previously the RequestOptions/ResponseOptions classes had constructors
with a destructured argument hash (represented by the
{Request,Response}OptionsArgs type). This type consists entirely of
optional members.
This produces a .d.ts file which includes the constructor declaration:
constructor({param, otherParam}?: OptionsArgs);
However, this declaration doesn't type-check properly. TypeScript
determines the actual type of the hash parameter to be OptionsArgs | undefined,
which it then concludes does not have a `param` or `otherParam` member.
This is a bug in TypeScript ( https://github.com/microsoft/typescript/issues/10078 ).
As a workaround, destructuring is moved inside the method, where it does not produce
broken artifacts in the .d.ts.
Fixes#16663.
This wraps the $interval service when using upgrade to run the
$interval() call outside the Angular zone. However, the callback is
invoked within the Angular zone, so changes still propagate to
downgraded components.
Refactoring the compiler to use transformers moves the code generation
after type-checking which suppresses the errors TypeScript would
generate in the user code.
`TypeChecker` currently produces the same factory code that was
generated prior the switch to transfomers, getting back the same
diagnostics as before. The refactoring will allow the code to
diverge from the factory code and allow better diagnostic error
messages than was previously possible by type-checking the factories.
These files are needed so that:
- user code can compile even without real codegen
- as tsc transformers cannot create but only change existing files
in the transformation pipeline.
This is required as e.g. `token` from `@Inject` is
accessed in string form via makeParamDecorator
but as a property in the `ReflectiveInjector`.
Closes#16889 as this is a more general fix.
Add source location as a note tag as `<note category="location">path/to/file.ts:start_line[,end_line]</note>`.
`[,end_line]` part is optional and specified only if the end line is different from the start line.
Fixes #16531
`flush()` can now be used from within fakeAsync tests to simulate moving
time forward until all macrotask events have been cleared from the
event queue.
This fixes a flicker when transitioning from server rendered page to client rendered page in lazy loaded routes by waiting for the lazy loaded route to finish loading, assuming initialNavigation on the route is set to 'enabled'.
Fixes#15716
Hybrid apps (mix of Angular and AngularJS) might return AngularJS implementation
of Promises that do not play well with the change detection. Wrapping them in
native Promises fix this issue.
This could be the case when a Resolver returns a `$q` promise.
Use bracket notation to access $inject in downgradeInjectable to
support property renaming. Since the return type is any,
Closure compiler renames $inject.
* refactor(core): provide error message in stack for reflective DI
Fixes#16355
* fix(compiler): make AOT work with `noUnusedParameters`
Fixes#15532
* refactor: use view engine also for `NgModuleFactory`s
This is a prerequisite for being able to mock providers
in AOTed code later on.
Template expressions can now use a post-fix `!` operator
that asserts the target of the operator is not null. This is
similar to the TypeScript non-null assert operator. Expressions
generated in factories will be generated with the non-null assert
operator.
Closes: #10855
Only one h1 is allowed per document, and this is provided by the template.
So we cannot have any h1 tags (or `#` markdown shorthand) in any API docs.
Closes#16193
* docs(animations): fix links to `Component` animations
* docs(core): fix links to `ReflectiveInjector` methods
The `resolve` and other methods were moved from the
`Injector` to the `ReflectiveInjector`.
* docs(core): fix links to `Renderer`
The local links were assuming that that methods were on the
current document (e.g. `RootRenderer`), but they are actually
on the `Renderer` class.
* docs(router): fix links to methods
* docs(forms): fix links to methods
* docs(core): fix links to methods
* docs(router): fix API page links and an internal link
