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
This can be used to e.g. add the NoopAnimationsModule by default:
```
TestBed.initTestEnvironment([
BrowserDynamicTestingModule,
NoopAnimationsModule
], platformBrowserDynamicTesting());
```
This change installs HttpModule with ServerModule, and overrides bindings to
service Http requests made from the server with the 'xhr2' NPM package.
Outgoing requests are wrapped in a Zone macro-task, so they will be tracked
within the Angular zone and cause the isStable API to show 'false' until they
return. This is essential for Universal support of server-side HTTP.
BREAKING CHANGE: web worker platform is now exported via separate packages.
Please use @angular/platform-webworker and @angular/platform-webworker-dynamic
This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.
Main part of #10043Closes#10164
BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
- Introduces `CompilerFactory` which can be part of a `PlatformRef`.
- Introduces `WorkerAppModule`, `WorkerUiModule`, `ServerModule`
- Introduces `serverDynamicPlatform` for applications using runtime compilation
on the server.
- Changes browser bootstrap for runtime and offline compilation (see below for an example).
* introduces `bootstrapModule` and `bootstrapModuleFactory` in `@angular/core`
* introduces new `browserDynamicPlatform` in `@angular/platform-browser-dynamic
- Changes `initTestEnvironment` (which used to be `setBaseTestProviders`) to not take a compiler factory any more (see below for an example).
BREAKING CHANGE:
## Migration from `setBaseTestProviders` to `initTestEnvironment`:
- For the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {initTestEnvironment} from ‘@angular/core/testing’;
import {browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
BrowserDynamicTestModule,
browserDynamicTestPlatform());
```
- For the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {initTestEnvironment} from ‘@angular/core/testing’;
import {serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
ServerTestModule,
serverTestPlatform());
```
## Bootstrap changes
```
@AppModule({
modules: [BrowserModule],
precompile: [MainComponent],
providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {
constructor(appRef: ApplicationRef) {
appRef.bootstrap(MainComponent);
}
}
// offline compile
import {browserPlatform} from ‘@angular/platform-browser’;
import {bootstrapModuleFactory} from ‘@angular/core’;
bootstrapModuleFactory(MyModuleNgFactory, browserPlatform());
// runtime compile long form
import {browserDynamicPlatform} from ‘@angular/platform-browser-dynamic’;
import {bootstrapModule} from ‘@angular/core’;
bootstrapModule(MyModule, browserDynamicPlatform());
```
Closes#9922
Part of #9726
Every test now has an implicit module. It can be configured via `configureModule` (from @angular/core/testing)
to add providers, directives, pipes, ...
The compiler now has to be configured separately via `configureCompiler` (from @angular/core/testing)
to add providers or define whether to use jit.
BREAKING CHANGE:
- Application providers can no longer inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead. This reflects the
changes to `bootstrap` for module support (3f55aa609f).
- Compiler providers can no longer be added via `addProviders` / `withProviders`.
Use the new method `configureCompiler` instead.
- Platform directives / pipes need to be provided via
`configureModule` and can no longer be provided via the
`PLATFORM_PIPES` / `PLATFORM_DIRECTIVES` tokens.
- `setBaseTestProviders()` was renamed into `initTestEnvironment` and
now takes a `PlatformRef` and a factory for a
`Compiler`.
- E.g. for the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {browserTestCompiler, browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
browserTestCompiler,
browserDynamicTestPlatform(),
BrowserDynamicTestModule);
```
- E.g. for the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {serverTestCompiler, serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
serverTestCompiler,
serverTestPlatform(),
ServerTestModule);
```
Related to #9726Closes#9846
Previously these symbols were exposed via platform-browser-dynamic, then we merged then into platform-browser
thinking that tools would know how to shake off the compiler and other dynamic bits not used with the offline
compilation flow. This turned out to be wrong as both webpack and rollup don't have good enough tree-shaking
capabilities to do this today. We think that in the future we'll be able to merge these two entry points into
one, but we need to give tooling some time before we can do it. In the meantime the reintroduction of the -dynamic
package point allows us to separate the compiler dependencies from the rest of the framework.
This change undoes the previous breaking change that removed the platform-browser-dynamic package.
