Download

emoji-button-2.9.4.min.js

Installation

If you are using a package manager like yarn or npm, you can install Emoji Button directly from the npm registry:

npm install @joeattardi/emoji-button

You can also download the minified JavaScript file and add it to your page via a <script> tag. This will create a global variable EmojiButton, which you can use to instantiate a picker.

Basic usage

The picker is shown by calling showPicker or togglePicker on the EmojiButton instance. When the user selects an emoji, the picker will emit the emoji event, which you can listen for and then handle the emoji according to your application's needs.

  import EmojiButton from '@joeattardi/emoji-button';

  const button = document.querySelector('#emoji-button');
  const picker = new EmojiButton();

  picker.on('emoji', emoji => {
    document.querySelector('input').value += emoji;
  });

  button.addEventListener('click', () => {
    picker.togglePicker(button);
  });

TypeScript note

Because the EmojiButton class is a default export, it requires a small tweak to import the library in a TypeScript project. There are two options:

1. Enable the esModuleInterop compiler option and import it normally as shown in the above example
2. Import the module using the following syntax: import EmojiButton = require('@joeattardi/emoji-button');.

For more details on this, please see https://www.typescriptlang.org/docs/handbook/modules.html#export--and-import--require.
