Mod and unmod

The MODE Twitch command delivers a slightly cryptic payload. We can expect '+o' as a middle parameter to mean 'mod' and '-o' to mean 'unmod'.

twitch.chat.inference('MODE', function (msg, channel, key, user) {
    const commands = { '+o': 'mod', '-o': 'unmod' };

    return {
        command: commands[key],
        params: [channel, user]
    };
});

twitch.chat.on('mod', function (msg, channel, user) {
    console.log(`${user} is a mod in ${channel}!`);
});

twitch.chat.on('unmod', function (msg, channel, user) {
    console.log(`${user} is no longer a mod in ${channel}!`);
});
