ngx-clipboard

What is ngx-clipboard?

ngx-clipboard is an Angular library that provides a simple way to copy text to the clipboard. It is designed to be easy to use and integrate into Angular applications, offering both directive and service-based approaches for copying text.

What are ngx-clipboard's main functionalities?

Directive-based Copy

This feature allows you to use a directive to copy text to the clipboard. By adding the `ngxClipboard` directive to a button and binding the `cbContent` property to the text you want to copy, you can easily enable copy functionality.

<button ngxClipboard [cbContent]="'Text to copy'">Copy Text</button>

Service-based Copy

This feature allows you to use a service to copy text to the clipboard. By injecting the `ClipboardService` into your component, you can call the `copy` method with the text you want to copy.

import { ClipboardService } from 'ngx-clipboard';

constructor(private clipboardService: ClipboardService) {}

copyText() {
  this.clipboardService.copy('Text to copy');
}

Copy from Input Element

This feature allows you to copy text from an input element. By referencing the input element and using the `copyFromInputElement` method of the `ClipboardService`, you can copy the text contained in the input element.

<input #inputText type="text" value="Text to copy">
<button (click)="clipboardService.copyFromInputElement(inputText)">Copy Text</button>

README

ngx-clipboard , F.K.A angular2-clipboard

From 6.0.0, there is no other JS dependency anymore. Just Angular.

It works with angular version 2.0.0 and up

To make more sense with the future versioning scheme of Angular, the directive selector is now rename to ngxClipboard

Other packages

• ngx-progressive-image-loader: it can lazy load img/picture, prevent reflow and seo friendly.

Dependencies

• If you need to use it on 2.x, please use version 7.x.x.
• If you need to use it on 4.x, please use version 8.x.x.
• If you need to use it on 5.x, please use version 10.x.x.
• If you need to use it on 8.x, please use version 12.x.x.
• If you need to use it on 9.x, please use version 13.x.x.

The code are pretty much the same, in v8.0.0 it uses InjectionToken which requires angular4 and above.

Install

You can get it on npm.

npm install ngx-clipboard --save

Open your module file e.g app.module.ts and update imports array

import { ClipboardModule } from 'ngx-clipboard';
...
imports: [
...
    ClipboardModule,
...
]

Usage

If you use SystemJS to load your files, you might have to update your config:

System.config({
    map: {
        'ngx-clipboard': 'node_modules/ngx-clipboard'
    }
});

Copy source

This library support multiple kinds of copy source.

• Setting cbContent attribute

<button ngxClipboard [cbContent]="'target string'">Copy</button>

You can assign the parent container to avoid focus trapper issue, #145

<div #container>
    <button ngxClipboard [cbContent]="'target string'" [container]="container">Copy</button>
</div>

• Setting an input target

....

<input type="text" #inputTarget />

<button [ngxClipboard]="inputTarget">Copy</button>

• Using copyFromContent from ClipboardService to copy any text you dynamically created.

import { ClipboardService } from 'ngx-clipboard'

...

constructor(private _clipboardService: ClipboardService){
...
}

copy(text: string){
  this._clipboardService.copyFromContent(text)
}

Callbacks

• cbOnSuccess callback attribute is triggered after copy was successful with $event: {isSuccess: true, content: string}

<button (cbOnSuccess)="copied($event)" [cbContent]="'example string'">Copied</button>

Or updating parameters directly like so

<button (cbOnSuccess)="isCopied = true" [cbContent]="'example string'">Copied</button>

• cbOnError callback attribute is triggered when there's failure in copying with $event:{isSuccess: false}

Conditionally render host

You can also use the structural directive *ngxClipboardIfSupported to conditionally render the host element

<button ngxClipboard *ngxClipboardIfSupported [cbContent]="'target string'" (cbOnSuccess)="isCopied = true">
    Copy
</button>

Handle copy response globally

To handle copy response globally, you can subscribe to copyResponse$ exposed by the ClipboardService

export class ClipboardResponseService {
  constructor(
    private _clipboardService: ClipboardService,
    private _toasterService: ToasterService
  ) {
    this.handleClipboardResponse();
  }

  handleClipboardResponse() {
    this._clipboardService.copyResponse$.subscribe((res: IClipboardResponse) => {
      if (res.isSuccess) {
        this._toasterService.pop('success', undefined, res.successMessage);
      }
    });
  }
}

Clean up temporary textarea used by this module after each copy to clipboard

This library creates a textarea element at the root of the body for its internal use. By default it only destroys it when the directive is destroyed. If you'd like it to be destroyed after each copy to clipboard, provide root level module configuration like this:

ClipboardService.configure({ cleanUpAfterCopy: true });

Special thanks to @DmitryEfimenko for implementing this feature
