利用モジュール:ngx-cookie-service

  • インストール
npm install ngx-cookie-service --save

利用方法

設定

  • app.module.tsのproviderに設定を追加
import { CookieService } from 'ngx-cookie-service';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpClientModule
  ],
  providers: [CookieService ],
  bootstrap: [AppComponent]
})
  • 利用するコンポーネントでもインポート
import { CookieService } from 'ngx-cookie-service';

constructor(
    private cookieService: CookieService
 ) { }

操作

cookieに保存

this.cookieService.set( 'test-key', 'test value' );

cookieからの読み取り

cookieValue = this.cookieService.get('test-key');

全ての項目を読み取り

const allCookies: {} = cookieService.getAll();

全ての項目を削除

cookieService.deleteAll();

Expires/Max-Age設定

  • デフォルト(指定無しの場合)は、「1969-12-31T23:59:59.000Z」が設定される。
    • 恐らく無期限では無さそう?
  • 日数指定の場合は、numberを指定(例:3日間の場合)
this.cookieService.set( 'test-expire', 'test-value', 3 );
  • 日時指定の場合は、Dateを指定(例:2018-05-04T23:59:59.000Zの場合)
const date: Date = new Date('2018-05-04T23:59:59.000Z');
this.cookieService.set( 'test-expire2', 'test-value2', date );
