angular-emojione

Angular EmojiOne

EmojiOne for Angular 2+.

Usage

To use this library, install both emojione and this library, angular-emojione, from npm.

$ npm install --save emojione angular-emojione

It is highly recommended you include the EmojiOne stylesheet to properly size the emoji in your app. Include the following <link> tag in your index.html.

<link rel="stylesheet" href="https://cdn.jsdelivr.net/emojione/2.2.7/assets/css/emojione.min.css"/>

Import the EmojiModule into your app.module.ts and add it to your imports array:

//...
import { EmojiModule } from 'angular-emojione';

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

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    //...
    EmojiModule
  ]
})
export class AppModule {}

You're now ready to go! Check out the documentation below for using the various pieces of this library.

Component

You can use the component for a single shortcode-to-emoji rendering. Simply use the markup below:

<emoji [shortname]="myVar"></emoji>

Where myVar is bound to a string with a single shortcode, such as :poop:. That component will then render the emoji.

Pipe

Using the pipe is simple. Below is a sample component that makes use of the EmojiPipe.

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

@Component({
  selector: 'app-root',
  template: `
    <div [innerHTML]="text | emoji"></div>
  `
})
export class AppComponent {
  text: string;

  constructor() {
    this.text = `This will be converted to EmojiOne emojis! :thumbsup: ❤️`;
  }
}

The pipe will then convert the text and the output will look like the following:

As EmojiOne simply replaces shortcodes and native unicode emoji, you will need to bind your output to the innerHTML attribute, as is shown in the example above.

Service

If you'd rather do conversions yourself, this library provides an easy to use service with various methods for managing your emoji! Simply import EmojiService where you wish to use it, like the example below:

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

import { EmojiService } from 'angular-emojione';

@Component({
  selector: 'app-root',
  template: `
    <div>Hello World!</div>
  `
})
export class AppComponent {

  constructor(public emojiService: EmojiService) {
    // Emoji Service methods are available to use!
  }
}

shortnameToImage()

This function takes a shortname, such as :thumbsup:, and returns an <img> tag with the corresponding EmojiOne emoji.

unicodeToShortname()

This function takes a native unicode emoji, like ❤️, and returns a the corresponding shortname, in this case, :heart:.

unicodeToImage()

This function takes a native unicode emoji, like ❤️, and returns an <img> tag with the corresponding EmojiOne emoji.

convertText()

This function takes a string and replaces all instances of native unicode emoji and shortnames with <img> tags with their corresponding EmojiOne emoji. This is what the angular-emojione library uses for its EmojiPipe.
