In the era of digital communication, emojis have become an essential tool for expressing emotions and adding nuance to text-based conversations. As a React developer, integrating emoji functionality into your applications can significantly enhance user experience and engagement. This is where react-emoji-picker comes into play, offering a flexible and customizable solution for adding emoji selection capabilities to your React projects.

What is react-emoji-picker?

react-emoji-picker is a powerful React library that enables developers to create Slack-like emoji pickers in their user interfaces. It provides a customizable component that displays a wide range of emojis, allowing users to easily select and insert them into text inputs or other areas of your application.

Key Features

  • Customizable UI: Tailor the appearance of the emoji picker to match your application’s design.
  • Flexible Integration: Easily incorporate the emoji picker into various parts of your React application.
  • Emoji Conversion: Convert emoji shortcodes (e.g., :laughing:) into actual emoji characters.
  • Extensive Emoji Support: Utilizes the Twemoji emoji set for a wide range of emoji options.

Getting Started with react-emoji-picker

Installation

To begin using react-emoji-picker in your project, you’ll need to install it via npm or yarn. Open your terminal and run one of the following commands:

Using npm:

npm install react-emoji-picker

Using yarn:

yarn add react-emoji-picker

Basic Usage

Let’s dive into a simple example of how to implement an emoji picker in your React application:

import React, { useState } from 'react';
import EmojiPicker from 'react-emoji-picker';
import emojiMap from 'react-emoji-picker/lib/emojiMap';

const EmojiInput: React.FC = () => {
  const [emoji, setEmoji] = useState<string | null>(null);
  const [showPicker, setShowPicker] = useState(false);

  const handleEmojiSelect = (selectedEmoji: string) => {
    setEmoji(selectedEmoji);
    setShowPicker(false);
  };

  return (
    <div>
      <input
        type="text"
        value={emoji || ''}
        onChange={(e) => setEmoji(e.target.value)}
        placeholder="Select an emoji"
      />
      <button onClick={() => setShowPicker(!showPicker)}>
        {showPicker ? 'Close' : 'Open'} Emoji Picker
      </button>
      {showPicker && (
        <EmojiPicker onSelect={handleEmojiSelect} />
      )}
    </div>
  );
};

export default EmojiInput;

In this example, we’ve created a simple input field with a button to toggle the emoji picker. When an emoji is selected, it’s displayed in the input field.

Advanced Usage

Customizing the Emoji Picker

react-emoji-picker offers various customization options to tailor the picker to your needs. Here’s an example of how you can style the emoji picker:

import React from 'react';
import EmojiPicker from 'react-emoji-picker';

const CustomEmojiPicker: React.FC = () => {
  const pickerStyles = {
    position: 'absolute' as const,
    top: '100%',
    left: 0,
    zIndex: 1000,
    backgroundColor: '#f0f0f0',
    border: '1px solid #ccc',
    borderRadius: '4px',
    boxShadow: '0 2px 5px rgba(0,0,0,0.1)',
  };

  return (
    <div style={{ position: 'relative' }}>
      <EmojiPicker
        onSelect={(emoji) => console.log('Selected:', emoji)}
        emojiPickerStyles={pickerStyles}
      />
    </div>
  );
};

export default CustomEmojiPicker;

This example demonstrates how to apply custom styles to the emoji picker container, giving you control over its appearance and positioning.

Integrating with Text Areas

For a more practical application, let’s look at how to integrate the emoji picker with a text area:

import React, { useState } from 'react';
import EmojiPicker from 'react-emoji-picker';
import emojiMap from 'react-emoji-picker/lib/emojiMap';

const EmojiTextArea: React.FC = () => {
  const [text, setText] = useState('');
  const [showPicker, setShowPicker] = useState(false);

  const handleEmojiSelect = (emoji: string) => {
    setText((prevText) => prevText + emoji);
  };

  const handleTextChange = (e: React.ChangeEvent<HTMLTextAreaElement>) => {
    setText(e.target.value);
  };

  return (
    <div>
      <textarea
        value={text}
        onChange={handleTextChange}
        placeholder="Type your message here..."
      />
      <button onClick={() => setShowPicker(!showPicker)}>
        {showPicker ? 'Close' : 'Open'} Emoji Picker
      </button>
      {showPicker && (
        <EmojiPicker onSelect={handleEmojiSelect} />
      )}
    </div>
  );
};

export default EmojiTextArea;

This implementation allows users to insert emojis directly into a text area, enhancing the typing experience in chat applications or comment sections.

Emoji Conversion and Validation

react-emoji-picker also provides utilities for converting emoji shortcodes and validating emoji inputs. Here’s an example of how to use these features:

import React, { useState } from 'react';
import emojiMap from 'react-emoji-picker/lib/emojiMap';

const EmojiValidator: React.FC = () => {
  const [input, setInput] = useState('');
  const [isValid, setIsValid] = useState(true);

  const validateEmoji = (value: string) => {
    const matched = emojiMap.filter((emoji) => `:${emoji.name}:` === value);
    setIsValid(matched.length > 0);
  };

  const handleInputChange = (e: React.ChangeEvent<HTMLInputElement>) => {
    const value = e.target.value;
    setInput(value);
    validateEmoji(value);
  };

  return (
    <div>
      <input
        type="text"
        value={input}
        onChange={handleInputChange}
        placeholder="Enter an emoji shortcode (e.g., :smile:)"
      />
      {isValid ? (
        <span>Valid emoji!</span>
      ) : (
        <span>Invalid emoji shortcode</span>
      )}
    </div>
  );
};

export default EmojiValidator;

This component demonstrates how to validate emoji shortcodes entered by users, providing immediate feedback on whether the input corresponds to a valid emoji.

Conclusion

react-emoji-picker offers a powerful and flexible solution for integrating emoji functionality into your React applications. By providing an intuitive picker interface and utilities for emoji conversion and validation, it enables developers to create rich, expressive user experiences.

While react-emoji-picker currently supports only the Twemoji set, its foundation on react-emoji opens the possibility for future expansions to include other emoji flavors like Emojione or custom sets.
