Introduction

0:00 this video tutorial walks you through building a fully functional AI chat application using tools like the chat GPT API Google's Bert and the Deep seek R1 model along the way you'll gain hands-on experience with backend setup mongodb integration and hugging face models Harris from coding cleverly developed this course we're trying to build a full stack AI powered web app using the M which is basically mongod DB EXP press react node.js stack with chat GPD API and this is going to be an excellent project to learn web development and it's going to go with a step-by-step guide I ass sure that no one knows any kind of knowledge of uh programming and we're going to go by you know Bare Bones so basically we're first of all making sure that we know JavaScript HTML and CSS these are the course prerequisites then we'll put the development environment we TR we'll try to install nodejs we'll have npm which is the node package manager installed as well as mongod DB we'll use an editor like VSS code for this course as well as use git to set up GitHub for Version

1:12 Control the project overview will include uh basically a mongod DB for storing user queries and responses expressjs for backend routing will have reactjs for building the user interface node.js as a server environment along with open AI chat GPT API for the API responses or the AI responses setting up the project basically going to do is initialize our backend so we're going to create a nodejs and express application and making sure we create all of the things that were required first thing I want to do is basically I would set up my back end I would use the mkdir command to basically create an uh okay so what I'm going to do is I'm going to call this application basically it's called a AI powered web app so I could say mkd AI powered app okay so I created a folder and you going to basically do AI powered app you're inside the folder if you go in here you'll see that there is an AI powered app folder inside there's nothing so essentially we're going to start out from here now the goal here what we have to do is we have to essentially get our backend uh you know set up so I'm going to create a a folder mkd AI chat app okay now I'm going to CD

2:48 again basically the step that we repeated so I feel like we can just delete that one okay so I'm just going to shift and okay you could also do it using the the command so rmd and then AI chat app basically that removes that folder that was on there okay and now what we want to do is we want to install so we just initialize our um backend files so when I do npm init hyphen y I wrote to C users all this and this created a package.json which looks like this okay and it has the main as the index.js which have to which we have to create um and after that what we have to do is install some of the dependencies so I'm going to make sure I'm in Visual Studio code I'm going to use code and Dot this is going to open up my visual studio code window so we're going to install backend dependencies and uh let's start out with the beginning so first of all let me do that which is controll and B just making sure that

3:58 this is down Okay so what I'm going to start out with is npm sorry so let me clear this CLS okay so we're going to say npm install we're going to install basically Express mongus EnV body
