From YouTube: JavaScript Chatbots - Memona Haq

Description

Did you know it's not that hard to build a Chatbot in JavaScript? All it takes is 15 minutes. Join me in this quick demo where we will build a basic Chatbot using the Hubot Framework.

This talk was recorded at the Jozi.JS meetup group on 20 September 2018.

A

Yeah hi guys Mimi I'm, a software developer at intellect I'm, currently placed at standard bank yeah. Oh yeah, I asked oh yeah, hi I thought you asked you a question. Okay, like I, didn't, say anything yet: okay, so chat. Bots chat. Bots are basically like any other computer application that have conversations with people while using either text or audio and they're two basic types of chat BOTS. They can be either simple or smart.

A

Simple chat, BOTS basically make use of key words and phrases and do some kind of like regex or other string analysis to catch commands, and you have to code every single command that you want your butt to reply. To way, for example, like tell me a joke, so the bar will look for the word: joke can be like. Oh, you probably want a joke and apply appropriately, and then you get smart chat, BOTS, which use a AI techniques like a natural language processing and basically take any input.

A

The user gives it and try to process it somehow and like flow the conversation in a way, then the main thing about smart BOTS. They learn from experience. So the more they talk to people, the more the better they get yeah.

A

So so you guys, you guys, have probably used a few chat BOTS in your life like if you have virtual assistants, like Alexa or Siri or Google assistant, and most other chat, BOTS found on like slack and other messaging applications and to choose if your bot needs to be smart or simple is basically, it began really depends on your use case. So if you have a virtual assistant, it needs to be smart because he needs to take in any input. The user gives it and somehow make sense of it ways.

A

If you have like a chat up spot for a company, it can be simple and you listen to commands like restarts over X.

A

Again next slide, so here are some examples of people chatting to see he's pretty funny, I couldn't choose, which ones to put they two hours later. I'm like thank you stuff, but yeah I. Give you guys few seconds to read a few this one's funny. This one.

A

Yeah, okay, so there are many many many chat boards but like how do you find them? They are such engines especially made for chat BOTS that the one there is a, but for this buttless you can go, find bots for inspiration or actually using them. You can empty slack telegram, they're, pretty simple, to add so building a chat, bot you're going to build your own chat bot. It's four simple steps, it's not as simple but like footsteps.

A

So if first of all, if you're trying to go what your body needs to do, second thing: is you have to choose a platform? What it really your pet, bought beyond a website really beyond, are on a mobile app on a messaging app like slack or telegram, and then you get to choose from ready-made reading match but frameworks or writing everything from scratch. And then you create customize and launch simple.

A

So some of the muttering works that are available you bought, which AI Microsoft bought frameworks. I fell upon you bot so that I kind of got to playing with it. So that's what I'm going to show you guys. So you got is basically your open source chat framework. It stood in CoffeeScript, which is said, but they are migrating everything to JavaScript now, so you, your scripts, can be either in CoffeeScript or JavaScript. They work all together because yeah and then you got is adaptable to many platforms like slack Trotter, chair telegram.

A

So that's why it's great! You can also write your own adapters if your messaging platform doesn't have a delta and I found it to be quite easily deployable using docker in a mixture of kubernetes docking everything. So that's how we deploy ours, it's data bank by the way, okay, this link at the bottom is a link to a bunch of you, but scripts that are already written. So you don't have to like write everything. I'll share the slides right, yeah, okay. So what do you need to build your own?

A

But you basically note in your computer and NPM and yeoman generator. It's basically a scale. Folding tool gives you a little a bunch of files just to get you up and going right away. So damnit I'm I'm checking code like that: okay, the sky and I will.

A

Yes, Mara, okay,.

A

So, basically, once again, don't look at that guy's, okay, so first thing we do need to do is get the yeoman generator, which is the scalping tool, as I mentioned and I already have it and it takes a while to install so I'm gonna just like cancel it now. Okay! Well, it works that works. Okay next thing, obviously you need to make a new folder for our bot. It's.

A

A

Josie J a spot.

A

And all you need to say: is you yo you what yeah but laughs, demos, okay, she's a name for your, but what your butt will do? What platform I'm, making the bat for so I'm gonna be making a telegram, but so just choose an adapter in no way to find it. You know all of that.

A

Okay, wait! There's my internet working! Yes, a bit! Okay, cool.

A

So yeah from as soon as this is done from the get-go, we can start talking to the what it has built and stuff. Just so you can test, is your butt working, so I'm going to do is say bin you bought and I'll run the guy. So this just it runs it using the shell adapter. So you can try test it out. You don't actually have to connect it and go find an API token for your platform and everything. So we can test there. Is it working? No wait? Joe zjs, but.

A

Pink yeah, it is punk. Okay, you can also say rules, it is cool, gives you the rules? Okay,.

A

So we don't just want to use a, but on the shell. Obviously we want to connect it to some kind of platform and it's fairly simple, to connect to telegram, because shadow made a bot to make Mobile's a but father. Basically so just go to telegram such a bad father, I, don't know why it's not bought mother. That makes more sense, cuz, okay, but yeah. So all you say is give me a new bot and exhaust you with the name, the username and that's it, and then it gives you an API token.

A

You have to save this, just keep hold of that and then there's your bot. So it's good to the bot yeah awesomesauce. Just don't read my chat on the side.

A

But you see okay, so I mean you. This is a like what it gives you from the get-go. There's an example that coffee sorry about CoffeeScript, the tester stuff will be in JavaScript I promise, and then you can just uncomment something here and see if it's working so don't run.

A

But it phone worked like this. You need an environment variable for your telegram token, and the second environment variable basically tells it. After how long should a poll telegram for messages and yeah give it a name? And the last thing is the adapter.

A

So yeah that looks fine.

A

I should work okay, there we go yeah. So if you look at the code, it's basically it's really really simple. I only started it, it says robot dot. Here it should hear anything, and this is basically ellagic s--, so it right now it will listen to this just right and you can just say: oh anything and like it can be followed by anything or stuff like that. You can customize it. However, you like it, so it it is a few few scripts. Let me just get it in the okay, so this first guy.

A

Basically sends key fees because keys are awesome, choose a random one and it'll send it to us. So basically, it'll, listen to anything, followed, oh, like followed by care for like give some way in the text. Basically, so just could you start this yeah.

A

Hopefully it's safe for work.

A

Yes, it is okay, awesome, okay, so these are basic things like basic parts for entertainment, but obviously you want to do work with these things, so I create another one, basically to make a new deployment on kubernetes I have mini cube running on my computer, since I mean like a little kubernetes cluster. So let's ask the bot: let's actually go to the code. First, okay, that's the kubernetes code, so we basically have basically we'll execute, commands and it'll be like what is up with. Basically, it's a command to check.

A

How's your namespace doing I have a namespace call milk in D. So if you want to ask your buddy you're at home late at night, you don't have VP and X's in like a bank system or something you can be like. What's up with my mouth cluster or something like that, and it will show you a summary of everything. Okay, we can try this out and second one will make a new deployment.

A

So if we go to the pot and say what's up no.

A

Okay, yeah, this I promise makes sense. If you know it's like little, you can form with it better. That was in a hurry, so yeah. This is this one deployment. Currently they and it's not working, but it's ok. It's not reduction. So right now on mini cube.

A

This is just proof that it does work, we have one deployment and then we can go to the pot again, a.

A

Second, come on was deployed on namespace, so.

A

Deploy is just a yellow file. I have lying it on in the same folder. On milk, oh.

A

Why couldn't you deploy.

A

ah Damn I didn't save it once again, I hot coated it. My bed.

A

A

Whoo-Hoo it worked so yeah, so basically you can do a lot with pots. The possibilities are endless, and this is just like the start of it. Managing your clusters, my infrastructure or sending reminders personal assistants. You can create your own and it's really simple with you but yeah. That's it.
