Hello fellow friends, just playing a bit with a Bot + slack decide to test locally with NPM + node.js which is just an easy go, it gets more complex when you build up the message structure as this is not an A.I we have to foresee the questions and responses.<\/p>\n

Lets get down to it
\nInstalling Node and NPM<\/strong><\/p>\n

1) Visit the official Node.js website to get the installer.
\n2) After download, run the installer.
\n3) Restart your computer to ensure the changes can take effect.<\/p>\n

\"\"<\/a><\/p>\n

The Node.js installer should have also installed\u00a0<\/span>NPM<\/a>\u00a0<\/span>for you. To confirm that you have installed both properly, you’ll need to open\u00a0<\/span>Windows Command Prompt<\/strong>\u00a0<\/span>if you’re on Windows, or\u00a0<\/span>Terminal<\/strong>\u00a0<\/span>if you’re on Mac or Linux.<\/p>\n

To check if you installed node:<\/p>\n

node -v<\/strong><\/p><\/blockquote>\n

To check if NPM is installed<\/p>\n

npm -v\u00a0<\/strong><\/p><\/blockquote>\n

If both of the commands return\u00a0results we are good to go.<\/p>\n

Initializing our Project and Installing Slackbots.js<\/strong><\/h2>\n

Create a folder anywhere you’d like to serve as the root directory for your bot. Navigate to that folder and initialize a new project by running<\/p>\n

npm init<\/p><\/blockquote>\n

Feel free to enter in whatever information you’d like. After that finishes running, you will be left with a file called.<\/span>package.json<\/code><\/p>\n

Now, to simplify our interactions with Slack’s\u00a0<\/span>Real Time Messaging API<\/a>, we will be using the\u00a0<\/span>Slackbots.js library<\/a>. To install Slackbots.js for use in our project, run the installation command:<\/p>\n

npm install slackbots – -save<\/strong><\/p><\/blockquote>\n

We are now ready to use Slackbots.js in our code!<\/span><\/p>\n

Creating a New Slack bot<\/strong><\/h2>\n

Let’s register a new bot on our slack instance. Head on over to:
\nhttps:\/\/yourinstancehere\/services\/new\/bot<\/code><\/p>\n

Replace with<\/span>instance<\/code><\/span> the name of your Slack instance. Once here, give your bot a name. We’ll call our bot\u00a0<\/span>AD-BOT<\/strong>.<\/p>\n

After you hit,Add bot integration<\/code> you’ll be provided with your bot’s\u00a0<\/span>API token<\/strong>. You’ll need this, later on, to save this somewhere. Additionally, you can also change the name of your bot, upload an icon, and set what channels your bot will operate inside.<\/span><\/p>\n

Building our Bot<\/strong><\/h2>\n

In the same directory that your\u00a0<\/span>package.json<\/code>\u00a0<\/span>lives in, create a new file called.<\/span>index.js<\/code> This file will serve as the code for your bot.<\/p>\n

This is my first code but you can adjust for your purposes
\n\/\/ create a bot<\/code><\/p>\n

var SlackBot = require(“slackbots”);
\nvar channel = “YourchannelHere”;<\/p>\n

var bot = new SlackBot({
\ntoken: “YOURTOKENHERE”,
\nname: “AD-BOT”
\n});<\/p>\n

bot.on(“start”, function() {
\nbot.postMessageToChannel(channel, “Welcome to Active Directory Channel”);
\nconsole.log(“BOT is now Live!”);
\n});<\/p>\n

bot.on(“message”, function(data) {
\nif (data.type !== “message”) {
\nreturn;
\n}<\/p>\n

handleMessage(data.text);
\n});<\/p>\n

function handleMessage(message) {
\nswitch(message) {
\ncase “hi”:
\ncase “hello”:
\nsendGreeting();
\nbreak;
\ndefault:
\nreturn;
\n}
\n}<\/p>\n

function sendGreeting() {
\nvar greeting = getGreeting();
\nbot.postMessageToChannel(channel, greeting);
\n}<\/p>\n

function getGreeting() {
\nvar greetings = [
\n“hello!”,
\n“hi there!”,
\n“Hi! Hope you are having fun today!”,
\n“how do you do!”,
\n“Howdy”
\n];
\nreturn greetings[Math.floor(Math.random() * greetings.length)];
\n}<\/p>\n

\"\"<\/a><\/p>\n

Our new code has our bot listen on the\u00a0<\/span>start<\/code>\u00a0<\/span>event which is fired when a connection to Slack is established. Once the event fires, it will run the provided function. In that function, we tell our bot to send the text\u00a0<\/span>Hello world!<\/code>\u00a0<\/span>to the channel you defined in the\u00a0<\/span>channel<\/code>variable. Finally, we threw in a\u00a0<\/span>console.log<\/code>\u00a0<\/span>just for good measure.<\/p>\n

Now it’s time to run our bot. To do so, simply run your\u00a0<\/span>index.js<\/code>\u00a0<\/span>file by running this command at the same directory:<\/p>\n


\n node index.js<\/code><\/p>\n

If everything went well, not only should you see printed\u00a0BOT is now Live!<\/span><\/span> on your console, but if you go to the designated channel on Slack, you should also see your bot saying Welcome to Active Directory Channel<\/code> in your channel, you can change that accordingly.<\/span><\/p>\n
