Extract hyperlink from message

[Dashi321]

I couldn't find the way to extract a link from a hyperlink within a text from a message that was sent in a channel.

You can parse the message to HTML and then extract links using regexp or the Cheerio DOM parser.
Example:

import {HTMLParser} from 'telegram/extensions/html';
import * as cherrio from 'cheerio';


const html = HTMLParser.unparse(message, entities);

const $ = cherrio.load(html);
// => Work with DOM like jQuery to extract your links
// => $("a:contains('Your Anchor')").attr("href");

switch (history.className) {
    case "messages.ChannelMessages":
        for (const message of history.messages) {
            switch (message.className) {
                case "Message":
                    for (const entity of message.entities || []) {
                        switch (entity.className) {
                            case "MessageEntityUrl":
                                const url = message.rawText.slice(entity.offset, entity.offset + entity.length)
                                console.log(url)
                                break
                        }
                    }
            }
        }
}
