Steps for rendering Emoji in React Application

I'm looking to integrate emojis into my webpage within a React chat app. The idea is to provide users with a list of emojis to choose from. How can I use codes like '1F683' to display emojis on the page, particularly with support for Chrome?

I have successfully utilized CSS to display emojis.

<div className="smiley"></div>

.smiley:after {
    content: "\01F683";
}

Another method I've explored is creating a list of images and mapping them to their corresponding codes to display an img element for each emoji.

Are there any other approaches, and which would be considered the best way to achieve this?

While I may be a bit tardy to the event, I found myself in a situation where I needed to dynamically display various emojis within the same component. Here is the approach that worked best for me:

Firstly, visit
Locate the emojis you require, such as U+1F609, and convert it to a hexadecimal string like 0x1F609 by utilizing String.fromCodePoint in your code as shown below:

Create a small component to adhere to the eslint rule that could otherwise trigger an error stating,

Emojis should be wrapped in <span>, have role="img", and have an accessible description with aria-label or aria-labelledby  jsx-a11y/accessible-emoji

:

const Emoji = React.memo(({ className, label, symbol }) =>
    <span className={className} role="img" aria-label={label}>
        {String.fromCodePoint(symbol)}
    </span>)

export default Emoji

Then, in another part of your code, you can incorporate it like this:

class MarvelousComponent extends PureComponent {
    getEmojiConditionally = () => this.props.happy ? '0x1F60A' : '0x1F61E'

    render = () =>
        <SpecificComponentWhereEmojiIsNeeded>
            <Emoji symbol={this.getEmojiConditionally(} />
        </SpecificComponentWhereEmojiIsNeeded>
}

Emojis are standardized using the format provided by the Emoji Cheat Sheet. For example, the code \01F683 corresponds to the emoji railway_car in the Emoji Cheat Sheet.

Storing emojis with these identifiers and mapping them to the actual emojis later can be a more efficient approach. This eliminates the need to encode the emojis themselves or struggle to remember the Unicode sequence (\01F683) associated with each emoji.

If you want to link the human-readable identifier to the Unicode symbol, you have different options. Take the example of railway_car:

Twemoji Awesome

Twemoji Awesome resembles Font Awesome but with Twitter Emojis.

To insert an emoji using Twemoji Awesome, you can use the following code, similar to Font Awesome:

<i class="twa twa-railway-car"></i>

This code will display the corresponding SVG:

Emoji Dictionary

An npm package named emoji-dictionary allows you to map emoji names to Unicode characters for use with the browser's default emoji renderer.

To use this package, you would write:

emoji.getUnicode("railway_car");

This function would return 🚃 (visible on most modern browsers, possibly causing display issues on older browsers).

If you're looking for the unicode of emojis, you can find it on the W3C website. The emojis range from {. Hex 2600-26FF.}.

With this information, you can easily generate emojis without relying on CSS.

Take a look at the example below 👇🏼

class Emoji extends React.Component  {

  render() {
    const {title, code} = this.props;
    return <span className="emoji" title={title}>{code}</span> 
  }
}

class App extends React.Component {

renderEmojis() {
  const rangeEmojis = Array.from({length: 256}, (v, k) => (k + 9728).toString(16));
  
  return rangeEmojis.map((code, index) => <Emoji code={unescape ('%u' + code)} title={"My code is :"+code} key={'emj'+index} />) 

} 

render() {

  return (
  
    <div>
      {this.renderEmojis()}
 
    </div>
  )
}

}

ReactDOM.render(<App />, document.querySelector('#chat'))

.emoji {
  border: solid 1px #3e3e3e;
  width: 50px;
  height: 50px;
  cursor:pointer;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>

Utilizing Typescript TS or enabling strict mode,

it is not possible to provide a string argument to String.fromCodePoint,

therefore, the argument must be a hexadecimal type number. You can achieve this by using the following method -

String.fromCodePoint(parseInt('0x1f603', 16))

Expected Output: 😃

If anyone happens to come across this post while searching for the same solution, I thought I'd share what worked for me.

<p>
I spent a while searching online and eventually just copied and pasted the emoji - it worked perfectly 🤷‍♂️.
</p>

I found the emoji by going to Discord, selecting the one I needed, and then copying and pasting it directly into my code. It displayed correctly on my screen.
