Can you help me with this please?

Thank you.

I get html like this

Hello, how are you? :thumbsup:

I would like to get something like this:

Hello, how are you? <Emoji emoji=':thumbsup:'  size={64} />

You will need a regex to detect the colons-syntax emojis, then you will be able to reconstruct your children with a mix of strings and Emoji components (given you already are in a React app)

Here’s a quick snippet of how we parse them in Missive:

let string = 'Hello, how are you? :thumbsup:'
let regex = new RegExp('(^|\\s)(\:[a-zA-Z0-9-_+]+\:(\:skin-tone-[2-6]\:)?)', 'g')

let match
while (match = colonsRegex.exec(string)) {
  let colons = match[2]
  let offset = match.index + match[1].length
  let length = colons.length

  console.log(colons, offset, length)
}

The colons variable can be used as-is w/ the Emoji component: <Emoji emoji={colons}>, it supports skin color too.

The rest (instead of the console.log) can vary depending on many factors, so I’ll let you figure out how that can be implemented in your app 😄

Thank you for your suggestion.

I would like to ask you about the implementation this awesome component with some input or textarea.
Can you share some code or suggest some example how implement this component with input/textbox? :)

BWT: second question - how display in component <Emoji emoji=':)' /> smile like this :)

how to set emoji into a textarea box or input box

[janbuerling]

Hello @kiranbabu189 , this is a bit complicated, but I have found a good solution.

I will explain it step by step.

1. Handler for the emoji-mart

Access the onClick method from the emoji-mart and act the chosen emoji.

onClick={this.handleClickEmojiIcon}

handleClickEmojiIcon(emoji) { ... }

2. Get the curser positon in textarea

Add these two lines to both componentDidMount and componentWillUnmount.

document.addEventListener('input', this.handleCursorPosition.bind(this), true);
document.addEventListener('click', this.handleCursorPosition.bind(this), true);

And create the method

handleCursorPosition(e) {
    if (e.target === this.textarea) {
      this.setState({ 
         curserPositonStart: e.target.selectionStart,
         curserPositonEnd: e.target.selectionEnd });
      }
  }

Be aware that you must place a reference on the textarea. I have called this in my case textarea.
ref={ref => (this.textarea = ref)}

3. The content of handleClickEmojiIcon method

const textareaStrParts = [
        `${this.textarea.value.substring(0, this.state.curserPositonStart)}`,
        `${emoji.native}`,
        `${this.textarea.value.substring(this.state.curserPositonEnd, this.length)}`,
      ];

      textareaValue = textareaStrParts.join('');

Then you can transfer the result back to the textarea.

I hope I could help you

@kiranbabu189 Please, if you create a detailed working sample, feel free to share it. :)

@janbuerling Why not just use the following this.textarea.selectionStart directly like so:

const textareaStrParts = [
        `${this.textarea.value.substring(0, this.textarea.selectionStart)}`,
        `${emoji.native}`,
        `${this.textarea.value.substring(this.textarea.selectionEnd, this.length)}`,
      ];

      textareaValue = textareaStrParts.join('');

I tried this and it works, however I feel I may be missing an edge case that you aren't...

Hi @EtienneLem Could you please help me figure this out. How I can render
var body = "Hello, how are you? <Emoji emoji=':thumbsup:' size={64} />" with

<div dangerouslySetInnerHTML={{__html: body}}></div>

[EtienneLem]

Only way I can think of, but only works with native emojis:

var EmojiMart = require('emoji-mart')
var body = "Hello, how are you? ${EmojiMart.emojiIndex.emojis['+1'].native}"

Because dangerouslySetInnerHTML doesn’t support components, only pure HTML. We could eventually add a toHTML function to the component that would return an HTML string.

[ajbeaven]

I'd be keen for a toHTML function. I'm working with a markdown component which requires its input to be supplied in a parameter (it too would be using dangerouslySetInnerHTML).

[ivawzh]

+1, I really need toHTML to support dangerouslySetInnerHTML too.

[veob]

Here is my solution to render native emoji as <Emoji /> components. Hope it'll be useful to somebody. Feel free to suggest improvements in the comments to the gist.

Whole code: https://gist.github.com/veob/1dfe6cfb39a4a5768ec66c5e2cec9574

The gist of the gist (sorry):

	let matchArr;
	let lastOffset = 0;
	const parts = [];
        // *children* is a string containing native emoji 

	while ((matchArr = regexp.exec(children)) !== null) {
		parts.push(children.substring(lastOffset, matchArr.index));

		// skip 2 chars, because an emoji is 2-chars wide
		lastOffset = matchArr.index + 2;

		const emoji = getByNative(matchArr[0]);

		if (emoji) {
			parts.push(<Emoji emoji={emoji.id} size={16} />);
		} else {
			parts.push(matchArr[0]);
		}
	}

	parts.push(children.substring(lastOffset, children.length));
