Package description
The @angular/common package is a core Angular library that provides commonly needed services, pipes, and directives that are essential for application development. It is part of the Angular framework and is used for tasks such as HTTP communication, localization, and various utility functions.
HTTP Client
Provides a simplified API for HTTP functionality which allows performing HTTP requests and handling responses within an Angular application.
import { HttpClientModule } from '@angular/common/http';
@NgModule({
imports: [
HttpClientModule
]
})
export class AppModule { }Common Directives
Includes directives like ngIf, ngFor, and ngSwitch which are essential for controlling the rendering of the template.
import { CommonModule } from '@angular/common';
@NgModule({
imports: [
CommonModule
]
})
export class SharedModule { }Location Services
Provides services for interacting with the browser's URL. Useful for routing and navigation within an Angular application.
import { Location } from '@angular/common';
@Component({
selector: 'app-component',
template: '<p>Current path: {{ location.path() }}</p>'
})
export class AppComponent {
constructor(public location: Location) { }
}Date, Currency, and Decimal Pipes
Provides built-in pipes for formatting data such as dates, currency, and numbers.
import { DatePipe, CurrencyPipe, DecimalPipe } from '@angular/common';
@Component({
selector: 'app-component',
template: '<p>Today is {{ today | date }}</p><p>Amount: {{ amount | currency }}</p>'
})
export class AppComponent {
today = new Date();
amount = 1234.56;
}React is a JavaScript library for building user interfaces. While it is not a one-to-one comparison with @angular/common, React provides a component-based architecture similar to Angular's directives and services.
Vue.js is a progressive JavaScript framework used for building UIs and single-page applications. It offers similar directives and reactivity systems but is generally considered to be more lightweight and easier to integrate into projects than Angular.
Axios is a promise-based HTTP client for the browser and Node.js. It provides many of the same HTTP client capabilities as the HttpClientModule in @angular/common.
Moment.js is a library for parsing, validating, manipulating, and formatting dates. It is similar to the DatePipe in @angular/common but is a standalone library focused solely on date manipulation.
Changelog
18.0.0-next.1 (2024-03-20)
RESOURCE_CACHE_PROVIDER APIs have been removed.deprecated platformDynamicServer has been removed. Add an import @angular/compiler and replace the usage with platformServer
deprecated ServerTransferStateModule has been removed. TransferState can be use without providing this module.
deprecated useAbsoluteUrl and baseUrl been removed from PlatformConfig. Provide and absolute url instead.
Legacy handling or Node.js URL parsing has been removed from ServerPlatformLocation.
The main differences are;
pathname is always suffixed with a /.port is empty when http: protocol and port in url is 80port is empty when https: protocol and port in url is 443Route.redirectTo to be a function
in addition to the previous string. Code which expects redirectTo to
only be a string on Route objects will need to be adjusted.| Commit | Type | Description | | -- | -- | -- | | 879bd80b57 | fix | capture data bindings for content projection purposes in blocks (#54876) |
