How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

Performance: It delivers optimal performance.
Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
UI design: React Native enables you to design simple and responsive UI for your mobile app.
3rd party plugins: This framework supports 3rd party plugins.
Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
Near-native user experience: React Native provides several native components, and these are platform agnostic.
The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Angular Datepicker：Angular13でDatepickerを使用する方法

Angular Materialは、 Web、モバイル、デスクトップで機能する重要で最新のUIコンポーネントを備えた地上運用です。

Angular Materialコンポーネントは、ブラウザーの移植性と互換性、デバイスの独立性、適切な機能低下などの最新のWebデザイン原則を維持しながら、魅力的なUIとUX、一貫性のある機能的なWebページ、およびWebアプリケーションを構築するのに役立ちます。

Angular Datepicker

Angular Datepickerは、テキスト入力またはカレンダーから日付を選択して日付を入力できる組み込みのマテリアルコンポーネントです。Angular Material Datepickerを使用すると、ユーザーはテキスト入力またはカレンダーから日付を選択して日付を入力できます。Material Datepickerは、連携して機能するいくつかのコンポーネントとディレクティブで構成されています。

これは、連携して機能するさまざまな角度コンポーネントとディレクティブで構成されています。まず、Angularをインストールする必要があります。 AngularCLIを使用して Angularをインストールしてい ます。

ステップ1：AngularCLIをインストールします。

次のコマンドを入力します。

npm install -g @angular/cli

次に、次のコマンドを使用してAngularプロジェクトを作成します。

ng new datepicker

ステップ2：他のライブラリをインストールします。

プロジェクトに移動し、次のコマンドを使用してhammerjs をインストールします。

npm install --save hammerjs

Hammer.jsはオプションの依存関係であり、いくつかのコンポーネントのタッチサポートに役立ちます。

次に、次のコマンドを使用してAngularMaterial と AngularAnimations をインストールします。

npm install --save @angular/material @angular/animations @angular/cdk

ここで、 angular.json ファイル内に hammerjs を含めます。このファイルはプロジェクトのルートにあります。

ステップ3：作成済みのテーマとマテリアルアイコンをインポートします。

Angular Materialには、いくつかの事前に作成されたテーマが付属しています。これらのテーマは、色と基本的なスタイリングを際立たせています。

利用可能な主なテーマは、 インディゴピンク、ディープパープルアンバー、 パープルグリーン、 ピンク ブルーグレーです。

テーマをインポートするには、次のコードをグローバル styles.css ファイルに追加します。ファイルはsrc フォルダー内にあります。

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

マテリアルデザインアイコンにアクセスして、 <mat-icon> コンポーネントで名前付きアイコンを使用することもできます。

それらをプロジェクトにインポートする場合は、これをプロジェクトのルート index.html ファイルのheadセクションに追加できます。

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Datepicker</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
<body>
  <app-root></app-root>
</body>
</html>

ステップ4：カスタムマテリアルモジュールファイルを作成します。

src、>> app フォルダー内に、 material.module.ts というファイルを1つ作成し、次のコードを追加します。

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule } from '@angular/material';

@NgModule({
  imports: [
    MatDatepickerModule
  ],
  exports: [
    MatDatepickerModule
  ]
})

export class MaterialModule {}

MatDatepickerModule、MatNativeDateModule、およびAngularDatepickerサンプル アプリに必要なその他のコンポーネントをインポートしました。

必要に応じて、将来的にコンポーネントを追加できます。

このファイルにはすべてのマテリアルコンポーネントを簡単に含めることができるため、このファイルは独自に作成され、このファイルはapp.module.ts内にインポートされます。

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule,
        MatNativeDateModule,
        MatFormFieldModule,
        MatInputModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  exports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  providers: [ MatDatepickerModule ],
})

export class MaterialModule {}

ステップ5：App.module.tsファイルにMaterialModuleをインポートします。

app.module.ts ファイル内にMaterialModuleをインポートします。

// app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { MaterialModule } from './material.module';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MaterialModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

また、最後に、app.component.html ファイル内にDatepickerHTMLコードを記述します。

<!-- app.component.html -->

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

ファイルを保存し、ターミナルまたはcmdに移動して、AngularDevelopmentServerを起動します。

ng serve --open

AngularDatepickerの例| AngularでDatepickerを使用する方法

ブラウザに移動すると、次の画像のようなものが表示されます。

ステップ6：日付ピッカーを入力に接続する

日付ピッカーは、テキスト入力とカレンダーポップアップで構成され、テキスト入力のmatDatePicker プロパティを介して接続されます。

<input [matDatepicker]="myDatepicker">
<mat-datepicker #myDatepicker></mat-datepicker>

オプションの日付ピッカートグルボタンが利用可能です。上記の例にトグルボタンを追加できます。

<input [matDatepicker]="myDatepicker">
<mat-datepicker-toggle [for]="myDatepicker"></mat-datepicker-toggle>
<mat-datepicker #myDatepicker></mat-datepicker>

<mat-form-field>の一部である入力でも同じように機能し、トグルボタンをマテリアル入力のプレフィックスまたはサフィックスとして簡単に使用できます。

<mat-form-field>
  <input matInput [matDatepicker]="myDatepicker">
  <mat-datepicker-toggle matSuffix [for]="myDatepicker"></mat-datepicker-toggle>
  <mat-datepicker #myDatepicker></mat-datepicker>
</mat-form-field>

ステップ7：カレンダーの開始ビューを設定する

<mat-datepicker>の startViewプロパティを使用して、カレンダーを最初に開いたときに表示される外観を設定できます。月、年、または複数年に構成できます。デフォルトでは、月表示を開始します。

カレンダーが開く月、年、または年の範囲は、最初に日付が現在選択されているかどうかを確認することによって決定され、選択されている場合は、その日付を含む月または年が開きます。それ以外の場合は、1か月または1年で開き、今日の日付を提供します。

この動作は、 <mat-datepicker>のstartAt プロパティを使用して簡単にオーバーライドできます。この場合、カレンダーは startAt 日付を含む月または年に開きます。

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker startView="year" [startAt]="startDate"></mat-datepicker>
</mat-form-field>

AngularMaterialDatepickerサンプルチュートリアル

コードはGithubにあります。

GITHUBコード

AngularDatepickerの検証

3つのプロパティにより、日付検証がdatepicker入力に追加されます。

最初の2つは、最小プロパティと最大プロパティです。

また、入力の検証を強制するために、これらのプロパティは、それぞれの値の前後のカレンダーポップアップのすべての日付を無効にし、ユーザーが最小または最大の日付を含む月または年（現在のビューに応じて）を超えてカレンダーを進めるのを防ぎます。

次のHTMLマークアップを参照してください。

<mat-form-field class="example-full-width">
  <input matInput [min]="minDate" [max]="maxDate" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

また、上記のマークアップに関連するtypescriptファイルも参照してください。

import {Component} from '@angular/core';

/** @title Datepicker with min & max validation */
@Component({
  selector: 'datepicker-min-max-example',
  templateUrl: 'datepicker-min-max-example.html',
  styleUrls: ['datepicker-min-max-example.css'],
})
export class DatepickerMinMaxExample {
  minDate = new Date(2000, 0, 1);
  maxDate = new Date(2020, 0, 1);
}

日付検証を追加する2番目の方法は、datepicker入力のmatDatepickerFilterプロパティを使用することです。

このプロパティは、<D> =>ブール値の関数を受け入れます（<D>は、datepickerで使用される日付型です。日付の実装の選択を参照してください）。

真の結果は日付が有効であることを示し、偽の結果は日付が有効でないことを示します。

繰り返しますが、これにより、無効なカレンダーの日付も無効になります。

ただし、matDatepickerFilterを使用する場合とminまたはmaxを使用する場合の重要な違いは、特定のポイントの前後のすべての日付を除外しても、ユーザーがそのポイントを超えてカレンダーを進めることを妨げないことです。

次のコード例を参照してください。最初にHTMLマークアップを参照してください。

<mat-form-field class="example-full-width">
  <input matInput [matDatepickerFilter]="myFilter" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

ここで、上記のマークアップに関連するTypescriptファイルを参照してください。

import {Component} from '@angular/core';

/** @title Datepicker with filter validation */
@Component({
  selector: 'datepicker-filter-example',
  templateUrl: 'datepicker-filter-example.html',
  styleUrls: ['datepicker-filter-example.css'],
})
export class DatepickerFilterExample {
  myFilter = (d: Date): boolean => {
    const day = d.getDay();
    // Prevent Saturday and Sunday from being selected.
    return day !== 0 && day !== 6;
  }
}

この例では、ユーザーは2005年を過ぎて戻ることができますが、それ以前のすべての日付は選択できなくなります。彼らは2000年よりもカレンダーに戻ることはできません。

最小値の前、最大値の後、またはフィルターで除外された日付を手動で入力すると、入力に検証エラーが発生します。

各検証プロパティには、チェックできる異なるエラーがあります。

たとえば、minプロパティに違反する値には、matDatepickerMinエラーがあります。
maxプロパティに違反する値には、matDatepickerMaxエラーがあります。
matDatepickerFilterプロパティに違反する値には、matDatepickerFilterエラーがあります。

角度入力および変更イベント

入力のネイティブ（入力）および（変更）イベントは、入力要素とのユーザーインタラクションのみをトリガーします。ユーザーがカレンダーポップアップから日付を選択しても、これらは起動しません。

したがって、datepicker入力は、（dateInput）および（dateChange）イベントもサポートします。これらは、ユーザーが入力またはポップアップのいずれかを操作したときにトリガーされます。

（dateInput）イベントは、ユーザーがカレンダーから日付を入力または選択したために値が変更されるたびに発生します。同様に、（dateChange）イベントは、ユーザーが入力の入力を終了するたびに（<input>ブラーで）、またはユーザーがカレンダーから日付を選択したときに発生します。

次のHTMLマークアップを参照してください。

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Input & change events"
         (dateInput)="addEvent('input', $event)" (dateChange)="addEvent('change', $event)">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

<div class="example-events">
  <div *ngFor="let e of events">{{e}}</div>
</div>

次に、そのマークアップに関連するtypescriptファイルを参照してください。

import {Component} from '@angular/core';
import {MatDatepickerInputEvent} from '@angular/material/datepicker';

/** @title Datepicker input and change events */
@Component({
  selector: 'datepicker-events-example',
  templateUrl: 'datepicker-events-example.html',
  styleUrls: ['datepicker-events-example.css'],
})
export class DatepickerEventsExample {
  events: string[] = [];

  addEvent(type: string, event: MatDatepickerInputEvent) {
    this.events.push(`${type}: ${event.value}`);
  }
}

AngularDatepickerの一部を無効にする

他の標準の<input>と同様に、disabledプロパティを追加することで、datepicker入力を無効にすることができます。

デフォルトでは、<mat-datepicker>と<mat-datepicker-toggle>は<input>から無効な状態を継承しますが、これは、datepickerまたはtoggle要素にdisabledプロパティを設定することでオーバーライドできます。

これは、テキスト入力を無効にしたいが、カレンダーを介した選択を許可したい場合、またはその逆の場合に非常に便利です。

次のHTMLマークアップを参照してください。

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp1" placeholder="Completely disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp1"></mat-datepicker-toggle>
    <mat-datepicker #dp1></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp2" placeholder="Popup disabled">
    <mat-datepicker-toggle matSuffix [for]="dp2" disabled></mat-datepicker-toggle>
    <mat-datepicker #dp2></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp3" placeholder="Input disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp3"></mat-datepicker-toggle>
    <mat-datepicker #dp3 disabled="false"></mat-datepicker>
  </mat-form-field>
</p>

ここで、typescriptファイルを参照してください。

import {Component} from '@angular/core';

/** @title Disabled datepicker */
@Component({
  selector: 'datepicker-disabled-example',
  templateUrl: 'datepicker-disabled-example.html',
  styleUrls: ['datepicker-disabled-example.css'],
})
export class DatepickerDisabledExample {}

このチュートリアルは以上です。

npm install --save hammerjs

Hammer.js is the optional dependency and helps with touch support for a few components.

Now, install Angular Material and Angular Animations using the following command.

npm install --save @angular/material @angular/animations @angular/cdk

Now, include hammerjs inside the angular.json file. You can find this file at the root of the project.

3: Import a pre-built theme and Material icons.

Angular Material comes with some pre-built themes. These themes have set off the colors and basic styling.

The main available themes are indigo-pink, deeppurple-amber, purple-green, and pink-bluegrey.

To import the theme, you can add the following code to your global styles.css file. The file is inside the src folder.

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

You can also access the Material Design icons and use named icons with a <mat-icon> component.

If we want to import them to your project, we can add this to the head section of your project’s root index.html file.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Datepicker</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
<body>
  <app-root></app-root>
</body>
</html>

4: Create a Custom Material Module File.

Inside the src,>> app folder, create one file called material.module.ts and add the following code.

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule } from '@angular/material';

@NgModule({
  imports: [
    MatDatepickerModule
  ],
  exports: [
    MatDatepickerModule
  ]
})

export class MaterialModule {}

We have imported MatDatepickerModule, MatNativeDateModule, and other components that we need in our Angular Datepicker Example App.

We can add additional components in the future if we need to.

This file is written on its own because it is easy to include all the Material components in this file, and then this file will be imported inside the app.module.ts.

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule,
        MatNativeDateModule,
        MatFormFieldModule,
        MatInputModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  exports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  providers: [ MatDatepickerModule ],
})

export class MaterialModule {}

5: Import MaterialModule in an app.module.ts file.

Import MaterialModule inside the app.module.ts file.

// app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { MaterialModule } from './material.module';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MaterialModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Also, finally, write the Datepicker HTML code inside the app.component.html file.

<!-- app.component.html -->

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Save the file, go to a terminal or cmd, and start Angular Development Server.

ng serve --open

Angular Datepicker Example | How To Use Datepicker In Angular

Go to the browser, and see something like the below image.

6: Connecting a datepicker to an input

A datepicker comprises text input and a calendar popup, connected via the matDatePicker property on the text input.

<input [matDatepicker]="myDatepicker">
<mat-datepicker #myDatepicker></mat-datepicker>

There is an optional datepicker toggle button available. The toggle button can be added to the example above:

<input [matDatepicker]="myDatepicker">
<mat-datepicker-toggle [for]="myDatepicker"></mat-datepicker-toggle>
<mat-datepicker #myDatepicker></mat-datepicker>

It works the same with an input that is part of a <mat-form-field> and a toggle button can easily be used as a prefix or suffix on the material input:

<mat-form-field>
  <input matInput [matDatepicker]="myDatepicker">
  <mat-datepicker-toggle matSuffix [for]="myDatepicker"></mat-datepicker-toggle>
  <mat-datepicker #myDatepicker></mat-datepicker>
</mat-form-field>

7: Setting the calendar starting view

The startView property of <mat-datepicker> could be used to set the look that will show up when the calendar first opens. It can be configured to month, year, or multi-year; by default, it will begin to month view.

A month, year, or range of years that a calendar opens to is determined by first checking if any date is currently selected, and if so, it will open to a month or year containing that date. Otherwise, it will open in a month or year, providing today’s date.

This behavior can be easily overridden using the startAt property of <mat-datepicker>. In this case, a calendar will open to the month or year containing the startAt date.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker startView="year" [startAt]="startDate"></mat-datepicker>
</mat-form-field>

Angular Material Datepicker Example Tutorial

You can find the code on Github.

Angular Datepicker Validation

Three properties add the date validation to the datepicker input.

The first two are the min and max properties.

Also, to enforce validation on input, these properties will disable all the dates on the calendar popup before or after the respective values and prevent the user from advancing the calendar past the month or year (depending on current view) containing the min or max date.

See the following HTML markup.

<mat-form-field class="example-full-width">
  <input matInput [min]="minDate" [max]="maxDate" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Also, see the typescript file related to the above markup.

import {Component} from '@angular/core';

/** @title Datepicker with min & max validation */
@Component({
  selector: 'datepicker-min-max-example',
  templateUrl: 'datepicker-min-max-example.html',
  styleUrls: ['datepicker-min-max-example.css'],
})
export class DatepickerMinMaxExample {
  minDate = new Date(2000, 0, 1);
  maxDate = new Date(2020, 0, 1);
}

The second way to add the date validation is by using the matDatepickerFilter property of the datepicker input.

This property accepts a function of <D> => boolean (where <D> is the date type used by the datepicker, see Choosing a date implementation).

A true result indicates that the date is valid, and a false result suggests that it is not.

Again this will also disable the dates on a calendar that are invalid.

However, a critical difference between using matDatepickerFilter vs. using min or max is that filtering out all dates before or after a certain point will not prevent a user from advancing a calendar past that point.

See the following code example. See first the HTML markup.

<mat-form-field class="example-full-width">
  <input matInput [matDatepickerFilter]="myFilter" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Now, see the Typescript file related to the above markup.

import {Component} from '@angular/core';

/** @title Datepicker with filter validation */
@Component({
  selector: 'datepicker-filter-example',
  templateUrl: 'datepicker-filter-example.html',
  styleUrls: ['datepicker-filter-example.css'],
})
export class DatepickerFilterExample {
  myFilter = (d: Date): boolean => {
    const day = d.getDay();
    // Prevent Saturday and Sunday from being selected.
    return day !== 0 && day !== 6;
  }
}

In this example, the user can go back past 2005, but all of the dates before then will be unselectable. They will not be able to go further back in the calendar than 2000.

If they manually type in a date before the min, after the max, or filtered out, the input will have validation errors.

Each validation property has a different error that can be checked:

For example, the value that violates a min property will have the matDatepickerMin error.
The value that violates a max property will have the matDatepickerMax error.
The value that violates a matDatepickerFilter property will have the matDatepickerFilter error.

Angular Input and change events

The input’s native (input) and (change) events will only trigger user interaction with the input element; they will not fire when the user selects the date from the calendar popup.

Therefore, a datepicker input also has support for (dateInput) and (dateChange) events — these triggers when a user interacts with either an input or the popup.

The (dateInput) event will fire whenever the value changes due to the user typing or selecting a date from the calendar. Likewise, the (dateChange) event will fire whenever the user finishes typing input (on <input> blur) or when a user chooses the date from a calendar.

See the following HTML Markup.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Input & change events"
         (dateInput)="addEvent('input', $event)" (dateChange)="addEvent('change', $event)">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

<div class="example-events">
  <div *ngFor="let e of events">{{e}}</div>
</div>

Now, see the typescript file related to that markup.

import {Component} from '@angular/core';
import {MatDatepickerInputEvent} from '@angular/material/datepicker';

/** @title Datepicker input and change events */
@Component({
  selector: 'datepicker-events-example',
  templateUrl: 'datepicker-events-example.html',
  styleUrls: ['datepicker-events-example.css'],
})
export class DatepickerEventsExample {
  events: string[] = [];

  addEvent(type: string, event: MatDatepickerInputEvent) {
    this.events.push(`${type}: ${event.value}`);
  }
}

Disabling parts of the Angular Datepicker

As with any standard <input>, it is possible to disable the datepicker input by adding the disabled property.

By default, the <mat-datepicker> and <mat-datepicker-toggle> will inherit their disabled state from the <input>, but this can be overridden by setting a disabled property on the datepicker or toggle elements.

This is very useful if you want to disable the text input but allow selection via the calendar or vice-versa.

See the following HTML Markup.

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp1" placeholder="Completely disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp1"></mat-datepicker-toggle>
    <mat-datepicker #dp1></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp2" placeholder="Popup disabled">
    <mat-datepicker-toggle matSuffix [for]="dp2" disabled></mat-datepicker-toggle>
    <mat-datepicker #dp2></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp3" placeholder="Input disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp3"></mat-datepicker-toggle>
    <mat-datepicker #dp3 disabled="false"></mat-datepicker>
  </mat-form-field>
</p>

Now, see the typescript file.

import {Component} from '@angular/core';

/** @title Disabled datepicker */
@Component({
  selector: 'datepicker-disabled-example',
  templateUrl: 'datepicker-disabled-example.html',
  styleUrls: ['datepicker-disabled-example.css'],
})
export class DatepickerDisabledExample {}

That’s it for this tutorial.

Angular Datepicker: Cómo Usar Datepicker En Angular 13

Angular Material está funcionando desde cero con componentes de interfaz de usuario significativos y modernos que funcionan en la web , dispositivos móviles y computadoras de escritorio .

Los componentes de Angular Material nos ayudarán a construir una interfaz de usuario y una experiencia de usuario atractivas , páginas web y aplicaciones web consistentes y funcionales, manteniendo los principios de diseño web modernos, como la portabilidad y compatibilidad del navegador, la independencia del dispositivo y la degradación elegante.

Selector de fecha angular

Angular Datepicker es un componente de material incorporado que nos permite ingresar la fecha a través de la entrada de texto o eligiendo la fecha de un calendario. Angular Material Datepicker permite a los usuarios ingresar la fecha a través de la entrada de texto o eligiendo la fecha del calendario. Material Datepicker consta de varios componentes y directivas que funcionan juntos.

Se compone de varios componentes angulares y directivas que funcionan en conjunto. Primero, necesitamos instalar Angular. Estamos usando Angular CLI para instalar Angular.

Paso 1: Instale la CLI angular.

Escriba el siguiente comando.

npm install -g @angular/cli

Ahora, crea el proyecto Angular usando el siguiente comando.

ng new datepicker

Paso 2: Instale otras bibliotecas.

Ingrese al proyecto e instale hammerjs usando el siguiente comando.

npm install --save hammerjs

Hammer.js es la dependencia opcional y ayuda con la compatibilidad táctil para algunos componentes.

Ahora, instale Angular Material y Angular Animations usando el siguiente comando.

npm install --save @angular/material @angular/animations @angular/cdk

Ahora, incluya hammerjs dentro del archivo angular.json . Puede encontrar este archivo en la raíz del proyecto.

Paso 3: importa un tema preconstruido e íconos de materiales.

Angular Material viene con algunos temas prediseñados. Estos temas han resaltado los colores y el estilo básico.

Los principales temas disponibles son rosa índigo , ámbar morado oscuro , verde púrpura y gris azulado rosa .

Para importar el tema, puede agregar el siguiente código a su archivo global styles.css . El archivo está dentro de la carpeta src .

@import '~@angular/material/prebuilt-themes/indigo-pink.css';

También puede acceder a los íconos de Material Design y usar íconos con nombre con un componente <mat-icon> .

Si queremos importarlos a su proyecto, podemos agregar esto a la sección principal del archivo raíz index.html de su proyecto.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Datepicker</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons">
</head>
<body>
  <app-root></app-root>
</body>
</html>

Paso 4: cree un archivo de módulo de material personalizado.

Dentro de la carpeta src,>> app , cree un archivo llamado material.module.ts y agregue el siguiente código.

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule } from '@angular/material';

@NgModule({
  imports: [
    MatDatepickerModule
  ],
  exports: [
    MatDatepickerModule
  ]
})

export class MaterialModule {}

Hemos importado MatDatepickerModule, MatNativeDateModule y otros componentes que necesitamos en nuestra aplicación de ejemplo Angular Datepicker .

Podemos agregar componentes adicionales en el futuro si es necesario.

Este archivo se escribe solo porque es fácil incluir todos los componentes de Material en este archivo, y luego este archivo se importará dentro de app.module.ts.

// material.module.ts

import { NgModule } from '@angular/core';
import { MatDatepickerModule,
        MatNativeDateModule,
        MatFormFieldModule,
        MatInputModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  imports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  exports: [
    MatDatepickerModule,
    MatFormFieldModule,
    MatNativeDateModule,
    MatInputModule,
    BrowserAnimationsModule
  ],
  providers: [ MatDatepickerModule ],
})

export class MaterialModule {}

Paso 5: importe MaterialModule en un archivo app.module.ts.

Importe MaterialModule dentro del archivo app.module.ts .

// app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { MaterialModule } from './material.module';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    MaterialModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Además, finalmente, escriba el código HTML de Datepicker dentro del archivo app.component.html .

<!-- app.component.html -->

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Guarde el archivo, vaya a una terminal o cmd e inicie Angular Development Server.

ng serve --open

Ejemplo de selector de fecha angular | Cómo usar el selector de fechas en Angular

Vaya al navegador y vea algo como la imagen de abajo.

Paso 6: Conectar un selector de fechas a una entrada

Un selector de fecha consta de entrada de texto y una ventana emergente de calendario, conectados a través de la propiedad matDatePicker en la entrada de texto.

<input [matDatepicker]="myDatepicker">
<mat-datepicker #myDatepicker></mat-datepicker>

Hay un botón de alternar selector de fecha opcional disponible. El botón de alternar se puede agregar al ejemplo anterior:

<input [matDatepicker]="myDatepicker">
<mat-datepicker-toggle [for]="myDatepicker"></mat-datepicker-toggle>
<mat-datepicker #myDatepicker></mat-datepicker>

Funciona de la misma manera con una entrada que es parte de un <mat-form-field> y un botón de alternar se puede usar fácilmente como prefijo o sufijo en la entrada de material:

<mat-form-field>
  <input matInput [matDatepicker]="myDatepicker">
  <mat-datepicker-toggle matSuffix [for]="myDatepicker"></mat-datepicker-toggle>
  <mat-datepicker #myDatepicker></mat-datepicker>
</mat-form-field>

Paso 7: Configuración de la vista de inicio del calendario

La propiedad startView de <mat-datepicker> podría usarse para establecer el aspecto que se mostrará cuando se abra el calendario por primera vez. Puede configurarse para mes , año o varios años ; de forma predeterminada, comenzará a ver el mes.

Un mes, año o rango de años en los que se abre un calendario se determina comprobando primero si alguna fecha está actualmente seleccionada y, de ser así, se abrirá en un mes o año que contenga esa fecha. De lo contrario, se abrirá en un mes o año, proporcionando la fecha de hoy.

Este comportamiento se puede anular fácilmente usando la propiedad startAt de <mat-datepicker> . En este caso, se abrirá un calendario en el mes o año que contiene la fecha startAt .

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker startView="year" [startAt]="startDate"></mat-datepicker>
</mat-form-field>

Tutorial de ejemplo de selector de fecha de material angular

Puedes encontrar el código en Github.

CÓDIGO GITHUB

Validación de selector de fecha angular

Tres propiedades agregan la validación de fecha a la entrada del selector de fecha.

Los dos primeros son las propiedades min y max .

Además, para hacer cumplir la validación en la entrada, estas propiedades deshabilitarán todas las fechas en la ventana emergente del calendario antes o después de los valores respectivos y evitarán que el usuario avance el calendario más allá del mes o año (según la vista actual) que contiene la fecha mínima o máxima. .

Consulte el siguiente marcado HTML.

<mat-form-field class="example-full-width">
  <input matInput [min]="minDate" [max]="maxDate" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Además, consulte el archivo mecanografiado relacionado con el marcado anterior.

import {Component} from '@angular/core';

/** @title Datepicker with min & max validation */
@Component({
  selector: 'datepicker-min-max-example',
  templateUrl: 'datepicker-min-max-example.html',
  styleUrls: ['datepicker-min-max-example.css'],
})
export class DatepickerMinMaxExample {
  minDate = new Date(2000, 0, 1);
  maxDate = new Date(2020, 0, 1);
}

La segunda forma de agregar la validación de fecha es usando la propiedad matDatepickerFilter de la entrada del selector de fecha.

Esta propiedad acepta una función de <D> => booleano (donde <D> es el tipo de fecha utilizado por el selector de fecha, consulte Elección de una implementación de fecha).

Un resultado verdadero indica que la fecha es válida y un resultado falso sugiere que no lo es.

Nuevamente, esto también deshabilitará las fechas en un calendario que no son válidas.

Sin embargo, una diferencia crítica entre usar matDatepickerFilter y usar min o max es que filtrar todas las fechas antes o después de cierto punto no evitará que un usuario avance un calendario más allá de ese punto.

Consulte el siguiente ejemplo de código. Vea primero el marcado HTML.

<mat-form-field class="example-full-width">
  <input matInput [matDatepickerFilter]="myFilter" [matDatepicker]="picker" placeholder="Choose a date">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

Ahora, vea el archivo TypeScript relacionado con el marcado anterior.

import {Component} from '@angular/core';

/** @title Datepicker with filter validation */
@Component({
  selector: 'datepicker-filter-example',
  templateUrl: 'datepicker-filter-example.html',
  styleUrls: ['datepicker-filter-example.css'],
})
export class DatepickerFilterExample {
  myFilter = (d: Date): boolean => {
    const day = d.getDay();
    // Prevent Saturday and Sunday from being selected.
    return day !== 0 && day !== 6;
  }
}

En este ejemplo, el usuario puede retroceder hasta 2005, pero todas las fechas anteriores no podrán seleccionarse. No podrán retroceder más en el calendario que 2000.

Si escriben manualmente una fecha antes del mínimo, después del máximo o filtrada, la entrada tendrá errores de validación.

Cada propiedad de validación tiene un error diferente que se puede verificar:

Por ejemplo, el valor que viola una propiedad mínima tendrá el error matDatepickerMin.
El valor que viola una propiedad máxima tendrá el error matDatepickerMax.
El valor que viola una propiedad matDatepickerFilter tendrá el error matDatepickerFilter.

Entrada angular y eventos de cambio

Los eventos nativos (entrada) y (cambio) de la entrada solo activarán la interacción del usuario con el elemento de entrada; no se activarán cuando el usuario seleccione la fecha de la ventana emergente del calendario.

Por lo tanto, una entrada de selector de fecha también admite eventos (dateInput) y (dateChange), que se activan cuando un usuario interactúa con una entrada o la ventana emergente.

El evento (dateInput) se activará siempre que el valor cambie debido a que el usuario escribe o selecciona una fecha del calendario. Del mismo modo, el evento (dateChange) se activará cada vez que el usuario termine de escribir la entrada (en <input> blur) o cuando un usuario elija la fecha de un calendario.

Consulte el siguiente marcado HTML.

<mat-form-field>
  <input matInput [matDatepicker]="picker" placeholder="Input & change events"
         (dateInput)="addEvent('input', $event)" (dateChange)="addEvent('change', $event)">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

<div class="example-events">
  <div *ngFor="let e of events">{{e}}</div>
</div>

Ahora, vea el archivo mecanografiado relacionado con ese marcado.

import {Component} from '@angular/core';
import {MatDatepickerInputEvent} from '@angular/material/datepicker';

/** @title Datepicker input and change events */
@Component({
  selector: 'datepicker-events-example',
  templateUrl: 'datepicker-events-example.html',
  styleUrls: ['datepicker-events-example.css'],
})
export class DatepickerEventsExample {
  events: string[] = [];

  addEvent(type: string, event: MatDatepickerInputEvent) {
    this.events.push(`${type}: ${event.value}`);
  }
}

Deshabilitar partes de Angular Datepicker

Al igual que con cualquier <entrada> estándar, es posible deshabilitar la entrada del selector de fecha agregando la propiedad deshabilitada.

De forma predeterminada, <mat-datepicker> y <mat-datepicker-toggle> heredarán su estado deshabilitado de <input>, pero esto se puede anular configurando una propiedad deshabilitada en el selector de fecha o los elementos de alternancia.

Esto es muy útil si desea deshabilitar la entrada de texto pero permitir la selección a través del calendario o viceversa.

Consulte el siguiente marcado HTML.

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp1" placeholder="Completely disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp1"></mat-datepicker-toggle>
    <mat-datepicker #dp1></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp2" placeholder="Popup disabled">
    <mat-datepicker-toggle matSuffix [for]="dp2" disabled></mat-datepicker-toggle>
    <mat-datepicker #dp2></mat-datepicker>
  </mat-form-field>
</p>

<p>
  <mat-form-field>
    <input matInput [matDatepicker]="dp3" placeholder="Input disabled" disabled>
    <mat-datepicker-toggle matSuffix [for]="dp3"></mat-datepicker-toggle>
    <mat-datepicker #dp3 disabled="false"></mat-datepicker>
  </mat-form-field>
</p>

Ahora, vea el archivo mecanografiado.

import {Component} from '@angular/core';

/** @title Disabled datepicker */
@Component({
  selector: 'datepicker-disabled-example',
  templateUrl: 'datepicker-disabled-example.html',
  styleUrls: ['datepicker-disabled-example.css'],
})
export class DatepickerDisabledExample {}

Eso es todo por este tutorial.
