How to make the bot respond to @ or *?

Answer 1

An example is given using "vk-io". The implementation was available somewhere on this site, found, tested. Works.

const GROUP_ID = SOME_GROUP_ID;

const mentionPattern = new RegExp(
    String.raw`^(?:\[-${GROUP_ID}\|[^\]]+\])(?:[\s.,\'\"!?\-+]+|$)`,
    'i'
);

vk.updates.on('message', (context, next) => {
    if (context.isChat && !mentionPattern.test(context.text)) {
        return;
    }

    if (context.text) {
        context.text = context.text.replace(mentionPattern, '');   
    }

    return next();
});
