[Angular] よく使われるモジュール達 - @NgModuleとは何か (4)

Posted at

@NgModuleとは何かを知るシリーズ4回目です。
Angular付属のよく使うモジュールの紹介です。

今までの記事です。

BrowserModule

アプリケーションをブラウザ内で実行するのに必要です。
ほぼほぼ必須ですかね。

使い方
import { BrowserModule } from "@angular/platform-browser";

CommonModule

NgIfとかNgForとかを使うのに必要です。
BrowserModule読み込めば入ってます。

使い方
import { CommonModule } from "@angular/common";

FormsModule

input系のタグでNgModelを使うのに必要です。

使い方
import { FormsModule } from "@angular/forms";

ReactiveFormsModiule

NgModelではなく、新しいFormGroupFormControlを使うのに必要です。

使い方
import { ReactiveFormsModule } from "@angular/forms";

RouterModule

SPA(Single Page Application)を作る際に使います。

使い方
import { RouterModule } from "@angular/router";

HttpClientModule

サーバとHTTPでやり取りするの使います。

使い方
import { HttpClientModule } from "@angular/common/http";
