discord-message-handler

##About discord-message-handler is a module written to simplify message and command handling for discord.js bots and applications.

##Installation Simply navigate to your project's folder and type npm install discord-message-handler --save on the command line.

##Usage To start using the module you must require it into you script like this:

const MessageHandler = require('discord-message-handler');

Define rules for the message handler (shown below) then parse messages in the as they arrive:

client.on('message', message => {
    MessageHandler.handleMessage(message);
});

###Simple message handlers

MessageHandler.whenMessageContainsWord("shrug").reply("¯\\_(ツ)_/¯");
MessageHandler.whenMessageContains("lol").replySometimes("kek", 50);
MessageHandler.whenMessageContainsExact("dota").replyOne(["volvo pls", "rip doto"]);
MessageHandler.whenMessageContainsOne(["br", "brazil"]).reply("huehue");
MessageHandler.whenMessageStartsWith("help").then(message => doSomething(message));

###Command handler

MessageHandler.onCommand("/doit").do((args, rawArgs, message) => {
    message.channel.sendMessage(`Doing something for ${message.author}...`)
});

###Commands with usage info

MessageHandler 
    .onCommand("/info")
    .minArgs(2)
    .whenInvalid("Invalid command. Usage: /info <a> <b>")
    .do((args) => {
        doSomething(args[0]);
        doSomethingElse(args[1]);
    });

###Case sensitivity In case you want message filters to be case sensitive you just need to call this function once:

MessageHandler.setCaseSensitive(true);

By default all message filters are case insensitive. (false)

###Logging To enable logging call MessageHandler.enableLogging() and pass a function to handle logs.

MessageHandler.enableLogging((filterType, filter, message) => {
    console.log(`${new Date().toISOString()} ${filterType}: ${filter} - "${message.content}"`);
});
