The built-in pipe json is used to convert a JavaScript object into a JSON string. It is useful for debugging purposes or when you need to display the raw JSON data in your Angular application.

Usage

Assume you have a data object in your components which is an javascript object:

{
  "userId": 1,
  "id": 20,
  "title": "ullam nobis libero sapiente ad optio sint",
  "completed": true
}

In your template file, you can use the json pipe to convert the object into a JSON string:

1	<pre>{{ data \| json }}</pre>

You will get the following output on the rendered page:

1	{ "userId": 1, "id": 20, "title": "ullam nobis libero sapiente ad optio sint", "completed": true }

Without the json pipe, you will get [object Object] in the output.

Introduction

Deferrable views is a new feature in Angular 18 that allows you to defer the loading of a component until it is needed. This can help improve the performance of your application by reducing the initial bundle size.

How to use deferrable views

Load when browser is idle

Wrap your component with @defer {} to make it deferrable. In the following example, the app-product-detail component will be loaded only when the Browser is idle.

1
2
3

@defer {
  <app-product-detail></app-product-detail>
}

Load when component enter the viewport

You can also specify a condition for when the component should be loaded. In the following example, the app-product-detail component will be loaded when it enters the viewport.

Placeholder

Note that, defer on viewport must be used in conjunction with @placeholder directive. When component is out of viewport, the placeholder will be rendered.

@defer(on viewport) {
  <app-product-detail></app-product-detail>
} @placeholder() {
  <div>Default content</div>
}

To test this, you can add a long div element before the app-product-detail component to make it out of the viewport.

Loading section.

You’d better add a section to show the loading state of the component.

@defer(on viewport) {
  <app-product-detail></app-product-detail>
} @placeholder() {
  <div>Default content</div>
} @loading() {
  <div>Loading...</div>
}

To test the loading view, you can set the slow 3G network in the browser dev tools/network tab.

Error section

You can also specify an error section to show when the component fails to load.

@defer(on viewport) {
  <app-product-detail></app-product-detail>
} @placeholder() {
  <div>Default content</div>
} @loading() {
  <div>Loading...</div>
} @error() {
  <div>Error loading component</div>
}

This is not easy to test, not found a method yet.

Minium render time for placeholder and loading section.

To avoid flickering, you can specify a minimum render time for the placeholder and loading section. In the following example, the placeholder will be rendered for at least 200ms before the component is loaded, and the loading section will be rendered for at least 500ms.

Note that at least doesn’t mean exactly, for example, if the component didn’t load in 500ms, the loading section will keep showing until the component is loaded.

@defer(on viewport) {
  <app-product-detail></app-product-detail>
} @placeholder( minimum 200ms) {
  <div>Default content</div>
} @loading(minimum 500ms) {
  <div>Loading...</div>
}

Trigger conditions

Angular provides several trigger conditions for deferrable views. You can use the following conditions to specify when the component should be loaded.

Trigger	Description
idle	Triggers when the browser is idle.
viewport	Triggers when specified content enters the viewport
interaction	Triggers when the user interacts with specified element
hover	Triggers when the mouse hovers over specified area
immediate	Triggers immediately after non-deferred content has finished rendering
timer	Triggers after a specific duration

idle

This is the default option, the component will be loaded when the browser is idle.

1
2
3

@defer() {
  <app-product-detail></app-product-detail>
}

viewport

The component will be loaded when the specified content enters the viewport. If you didn’t specify the content, the component will be loaded when itself enters the viewport.

@defer (on viewport) {
  <app-product-detail></app-product-detail>
} @placeholder {
  <div>Default view</div>
}

You can also load the component when a specific element enters the viewport. In the following example, the app-product-detail component will be loaded when the greeting element enters the viewport.

<div #greeting>Hello!</div>
@defer (on viewport(greeting)) {
  <app-product-detail></app-product-detail>
}

interaction

The interaction trigger loads the deferred content when user interacts withe the specific element through click or keydown event.

By default, the placeholder acts as the interaction element. Placeholders used this way must have a single root element.

@defer (on interaction) {
  <app-product-detail></app-product-detail>
} @placeholder {
  <div>Default view</div>
}

You can also specify a different element for the interaction trigger. In the following example, the app-product-detail component will be loaded when the greeting element is clicked.

<div #greeting>Hello!</div>
@defer (on interaction(greeting)) {
  <app-product-detail></app-product-detail>
}

hover

Same as interaction, you can just replace interaction with hover in the above examples.

immediate

This is different than idle, the component will be loaded immediately after the non-deferred content has finished rendering.

@defer (on immediate) {
  <app-product-detail></app-product-detail>
} @placeholder {
  <div>Default view</div>
}

timer

The timer trigger loads the deferred content after a specific duration. You can specify the duration in milliseconds or seconds.

@defer (on timer(500ms)) {
  <app-product-detail></app-product-detail>
} @placeholder {
  <div>Default view</div>
}

when

The when trigger accepts a custom conditional expression and loads the deferred content when the condition becomes true. You can control the condition in our component class.

@defer (when condition) {
  <app-product-detail></app-product-detail>
} @placeholder {
  <div>Default view</div>
}

This is a one-time operation– the @defer block does not revert back to the placeholder if the condition changes to a falsy value after becoming truthy.

Conclusion

Conditions for deferrable views

Must be standalone.
Must not references outside of the @defer block in the same template file.

How it works

Angular use dynamic import to load the deferrable views.
The component loaded in @defer was bundled in a separated chunk.

Introduction

在Angular开发中经常要使用一些后台数据，下面是一个封装好的DataService服务，用于获取后台数据。数据来自：JSONPlaceholder

DataService

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

@Injectable({providedIn: 'root'})
export class DataService {
  constructor() {
  }

  async fetchTodoById(id: number) {
    const response = await fetch(`https://jsonplaceholder.typicode.com/todos/${id}`);
    return await response.json();
  }

  async fetch200Todos() {
    const response = await fetch(`https://jsonplaceholder.typicode.com/todos`);
    return await response.json();
  }
}

Data types

Todo

export interface Todo {
  userId: number;
  id: number;
  title: string;
  completed: boolean;
}

Introduction

Angular has a built-in pipe async that can be used to subscribe to an Observable or Promise and return the latest value it has emitted.

Without async pipe

Let’s see how we write the code without using the async pipe. In the following OrderComponent, we have a todo object that is fetched from the DataService using the fetchTodoById method which returns an Promise. We call the fetchTodos method in the ngOnInit lifecycle hook and assign the result to the todo property.

export class OrderComponent implements OnInit {
  todo: Todo | null = null;

  constructor(private dataService: DataService) {
  }

  fetchTodos() {
    return this.dataService.fetchTodoById(1);
  }

  ngOnInit() {
    this.fetchTodos().then(todo => {
      this.todo = todo
    })
  }
}

<div>
  <div>id: {{todo?.id}}</div>
  <div>userId: {{todo?.userId}}</div>
  <div>title: {{todo?.title}}</div>
  <div>completed: {{todo?.completed}}</div>
</div>

With async pipe

With async pipe, we don’t need to call then method on Promise, the async pipe will take care of it. We can directly assign the result of fetchTodos method to the todo property and use the async pipe in the template to subscribe to the Promise.

We need two changes in the code:

Change the type of todo property to Promise<Todo> | null.
Assign the result of fetchTodos method to the todo property.

export class OrderComponent implements OnInit {
  todo: Promise<Todo> | null = null; // <--- 1

  constructor(private dataService: DataService) {
  }

  fetchTodos() {
    return this.dataService.fetchTodoById(1);
  }

  ngOnInit() {
    this.todo = this.fetchTodos(); // <--- 2
  }
}

Note that we use the as syntax to assign the result of the async pipe to a template variable todo.

<div *ngIf="todo | async as todo">
  <div>id: {{todo.id}}</div>
  <div>userId: {{todo.userId}}</div>
  <div>title: {{todo.title}}</div>
  <div>completed: {{todo.completed}}</div>
</div>

Using with Observables

If using with Observable, just change the type of todo property to Observable<Todo> | null.

1	todo: Observable<Todo> \| null = null; // If using Observable

Using with `ngFor`

<div *ngFor="let todo of todos | async">
  <div>id: {{todo.id}}</div>
  <div>userId: {{todo.userId}}</div>
  <div>title: {{todo.title}}</div>
  <div>completed: {{todo.completed}}</div>
</div>

Benefits

When use with Observables, the async pipe automatically subscribes to the Observable, renders the output within the template, and then unsubscribes when the component is destroyed. - You don’t need to manually subscribe and unsubscribe.
Works with Promises as well.

angular-directive-ngfor

Posted on 2024-12-31 Edited on 2025-04-07 In angular
Symbols count in article: 284 Reading time ≈ 1 mins.

Introduction

NgFor is a structural directive in Angular, it is used to iterate over a list of items and render them in the template.

Usage

Suppose you have a months array in your component which contains ‘January’, ‘February’, ‘March’, and You want to render them in the template, you can use NgFor directive to achieve this.

// app.component.ts
@Component({
  selector: 'app-ng-for',
  templateUrl: './ng-for.component.html',
  styleUrls: ['./ng-for.component.less']
})
export class NgForComponent implements OnInit {
  months: string[] = ['January', 'February', 'March'];
  constructor() {}
  ngOnInit(): void {}
}

<!--app.component.html-->
<div class="months">
  <ul *ngFor="let month of months">
    <li>{{month}}</li>
  </ul>
</div>

Note that, *ngFor start iteration from the element where it is placed, in this case, it starts from the ul element and renders as below:

<div class="months">
  <ul>
    <li>January</li>
  </ul>
  <ul>
    <li>February</li>
  </ul>
  <ul>
    <li>March</li>
  </ul>
</div>

In order to render the list in a single ul element, you can place *ngFor on the li element:

<!--app.component.html-->
<div class="months">
  <ul>
    <li *ngFor="let month of months">{{month}}</li>
  </ul>
</div>

track index

If you want to track the index of the current item, you can use index, note index is zero-based.

<!--app.component.html-->
<div class="months">
  <ul>
    <li *ngFor="let month of months; let i = index">{{i + 1}}. {{month}}</li>
  </ul>
</div>

The code above will render as below:

<div class="months">
  <ul>
    <li>1. January</li>
    <li>2. February</li>
    <li>3. March</li>
  </ul>
</div>

Use `@for`

With the new built-in structural @for directive, you can use the following syntax:

<ul>
  @for(month of months; track $index) {
    <li>{{$index + 1}}. {{ month }}</li>
  }
</ul>

Introduction

Angular app build后会生成如下文件结构，其中main/polyfills/runtime文件中的xxx是Angular随机生成的hash值。

dist/
├─ angular-15/
│  ├─ assets/
│  ├─ 3rdpartylicenses.txt
│  ├─ favicon.ico
│  ├─ index.html
│  ├─ main.xxx.js
│  ├─ polyfills.xxx.js
│  ├─ runtime.xxx.js
│  ├─ styles.xxx.css

今天我们来分析一下main.js文件的内容。（注意，由于Angular编译后的代码是压缩过的，所以以下源码是使用ng server命令本地启动app后在浏览器中查看的。）

main.js文件主要定义了app中的各个组件，比如下面代码中的AppComponent、AppModule、HomeComponent、ProductComponent、AboutComponent等。

在这个文件里面用到的许多函数都是在runtime.xxx.js文件中定义的，比如：

__webpack_require__.r函数
__webpack_require__.d函数

每个component前面都有一个数字，比如HomeComponent前面的5067，表示该模块的id，这个id是webpack生成的，用来标识模块的唯一性。

Introduction

Angular app build后会生成如下文件结构，其中main/polyfills/runtime文件中的xxx是Angular随机生成的hash值。

dist/
├─ angular-15/
│  ├─ assets/
│  ├─ 3rdpartylicenses.txt
│  ├─ favicon.ico
│  ├─ index.html
│  ├─ main.xxx.js
│  ├─ polyfills.xxx.js
│  ├─ runtime.xxx.js
│  ├─ styles.xxx.css

polyfills.js文件主要是加载一些polyfills，用来兼容一些老的浏览器，当然也做一些额外的操作，比如zone.js的monkey patch。

(self["webpackChunkangular_15"] = self["webpackChunkangular_15"] || []).push([["polyfills"],{

Introduction

Angular app build后会生成如下文件结构，其中main/polyfills/runtime文件中的xxx是Angular随机生成的hash值。

dist/
├─ angular-15/
│  ├─ assets/
│  ├─ 3rdpartylicenses.txt
│  ├─ favicon.ico
│  ├─ index.html
│  ├─ main.xxx.js
│  ├─ polyfills.xxx.js
│  ├─ runtime.xxx.js
│  ├─ styles.xxx.css

今天我们来分析一下runtime.js文件的内容。（注意，由于Angular编译后的代码是压缩过的，所以以下源码是使用ng server命令本地启动app后在浏览器中查看的。）

Introduction

字符串操作是JS中非常常见的操作，本文将介绍JS中搜索字符串的几种方法。

判断是否包含某个字符串

String.prototype.indexOf()

在ES5中，我们通常使用indexOf方法来查找字符串中的子串。indexOf方法返回给定子串的第一个索引，如果不存在，则返回 -1。indexOf方法的语法如下：

1 2	indexOf(searchValue) indexOf(searchValue, fromIndex)

String.prototype.includes()

includes方法是ES6引入的，相比indexOf方法，includes方法更加直观。includes方法用于判断一个字符串是否包含另一个字符串。includes方法的语法如下：

String.prototype.startsWith()

startsWith也是ES6引入的方法，用于判断一个字符串是否以另一个字符串开头。startsWith方法的语法如下：

String.prototype.endsWith()

endsWith也是ES6引入的方法，用于判断一个字符串是否以另一个字符串结尾。endsWith方法的语法如下：

includes, startsWith, endsWith方法都可以传递第二个参数，表示从指定位置开始搜索。个人感觉没有必要。

Introduction

今天我们一起研究一下Angular App是如何运行的，今天主要讨论的是在生产环境下，Angular App是如何运行的。既然限定了生产环境，那么就不讨论开发环境相关的东西了，我们直接看编译后的代码如何运行。

Create Angular app

首先，我们需要创建一个Angular项目，这里我们使用Angular CLI来创建一个项目，具体的步骤可以参考这篇文章。

Build Angular App

然后，我们使用ng build --prod命令来构建我们的Angular项目，这个命令会将我们的项目编译成生产环境下的代码。编译完成后，我们会得到一个dist目录，里面包含了我们的项目的所有文件，如下图所示：

众所周知，index.html是前端项目的入口文件，我们看看这个文件的内容：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <title>Angular15</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="styles.ef46db3751d8e999.css">
</head>
<body>
    <app-root></app-root>
    <script src="runtime.17ade4109dbace19.js" type="module"></script>
    <script src="polyfills.7488d7e9e1657922.js" type="module"></script>
    <script src="main.301f0813b18ba60a.js" type="module"></script>
</body>
</html>

该文件主要执行以下操作：

加载styles.ef46db3751d8e999.css样式文件 - 这是项目打包后的样式文件。
加载runtime.17ade4109dbace19.js文件 - 这个文件的作用是初始化webpack相关的设置，比如加载模块的方法，为后续的代码运行做准备。
加载polyfills.7488d7e9e1657922.js文件 - 这个文件主要是加载一些polyfills，用来兼容一些老的浏览器，当然也做一些额外的操作，比如zone.js的monkey patch。
加载main.301f0813b18ba60a.js文件 - 这个文件是我们的项目的主要代码，我们书写的所有组件，服务等代码都会被编译到这个文件。

由于runtime/polyfills/main这三个文件打包后都是混淆的，我们无法查看其代码，所以我们还是借助开发环境，使用ng serve命令来查看这三个文件的内容。

以下是runtime.js的内容：
该文件主要是初始化一些Webpack的相关函数，用来为后续加载polyfills和main文件做准备。

注意代码末尾的self["webpackChunkangular_15"], 这里angular_15是我们的项目名称，webpackChunk是前缀。self是浏览器Window对象的一个属性。它就指向Window对象本身。详情参考这里：https://developer.mozilla.org/en-US/docs/Web/API/Window/self

其余代码我就不细说了，大伙有空自己看吧，都比较简单。
