Embed media and rich content in posts: youtube, vimeo, twitch etc. All embeds are based on the rules. You are encouraged to build your own rules to embed everything what is embeddable.

const specialChars = /[^\w]/gi;

export function getSanitizedName(value) {
    let result = value;

    if (value !== null && value !== undefined) {
        value = value.toLowerCase();
        value = value.replace(specialChars, '');
        result = value;
    }

    return result;
}
