botkit_hear_middleware.js

// From https://github.com/howdyai/botkit#hear-middleware

function custom_hear_middleware(patterns, message) {

    for (var p = 0; p < patterns.length; p++) {
        if (patterns[p] == message.text) {
            return true;
        }
    }
    return false;
}


controller.hears(['hello'],'direct_message',custom_hear_middleware,function(bot, message) {

    bot.reply(message, 'I heard the EXACT string match for "hello"');
