One exciting development in this field is ChatGPT, an advanced AI-based application that has captured our imagination.

In this blog post, we will explore how ChatGPT can be integrated with Node and Vue, two popular technologies.

Get ready to witness the extraordinary possibilities that arise when human creativity meets the power of AI. Let’s dive into the promising world of ChatGPT integration

The flow of ChatGPT Integration with Node and Vue

Note: ChatGPT recommends that we not store tokens on the client side instead of using the backend to request ChatGPT APIs.

Step 1: Dummy Project Setup

Combining Node.js and Vue.js in the ChatGPT project will open many exciting possibilities in web development.

With Node.js as the backend and Vue.js as the frontend, our project focuses on creating a connection between the two using a simple backend setup.

By configuring a single endpoint that accepts POST requests, we enable seamless communication between the frontend and the backend, ultimately integrating the powerful capabilities of ChatGPT.

This harmonious blend of technologies has the potential to elevate ordinary connections into extraordinary experiences.

When it comes to the front end, simplicity is the key. In this case, we have a ChatBox component that serves as the messenger between users and ChatGPT.

It’s responsible for sending messages and receiving the corresponding responses, making the interaction seamless and user-friendly.

Step 2: Set the OpenAI SDK/Package

OpenAI is like the middleman between users and the ChatGPT server. It’s the official package for ChatGPT, making communication smooth and easy. It’s the essential link that ensures a seamless and enjoyable experience for everyone involved.

Also, it is the official package for ChatGPT, to explore more and dive deeper into the details refer to the Documentation.

Next, we will install the OpenAI package in the backend with this command:

npm install openai

Now, we will configure chatGpt.controller.js which will communicate with ChatGPT APIs from the backend. See this:

chatGpt.controller.js

const {Configuration, OpenAIApi} = require('openai')

const askToChatGpt = async function (req, res) {

   /**
    * 1. Create/configure OpenAI Instance
    */
   const openAIInstance = await _createOpenAIInstance()

   /**
    * 2. Let's talk to chatGPT
    */
   await openAIInstance.createCompletion({
       model: 'text-davinci-003',
       prompt: req.body.message,
       temperature: 0,
       max_tokens: 500
   })
   .then((response) => {
       const repliedMessage = response.data.choices[0].text
       res.send({from: 'chatGpt', data: repliedMessage})
   })
   .catch((error) => {
       //Report error
       console.log('Error ', error)
   });
}
const _createOpenAIInstance = async () => {
   const conf = await new Configuration({
       apiKey: process.env['CHATGPT_TOKEN']
   })
   return await new OpenAIApi(conf)
}
module.exports = {
   askToChatGpt
}

Step 3: Set Up the Frontend

We’ve designed a special component called ChatBox.vue, which you can find in the /src/components directory.

This component plays a crucial role in connecting with the backend of our application. To make this connection possible, we rely on Axios, a powerful tool for handling API requests.

Now, here is an explanation of how we use Axios to communicate with our backend.

methods: {
   async sendMessage (message) {
    this. messages. push ({
     from: ‘user’,
     data: message
   })
   await axios.post('http://localhost:3000/ask-to-chat-gpt', {
     message: message
   })
   .then( (response) => {
      this. messages. push response. data)
   })
  }
}

This is how our ChatBox.vue component looks like this:

<template>
 <div class="hello">
   <h1>Ask to chatGpt</h1>
   <input v-model="currentMessage" type="text"> <span><button @click="sendMessage(currentMessage)">Ask</button></span>
   <div class="messageBox">
    <template v-for="message in messages">
     <div :class="message.from=='user' ? 'messageFromUser' :'messageFromChatGpt'" :key="message" v-html="message.data"></div>
   </template>
   </div>
 </div>
</template>

<script>
import axios from 'axios'
export default {
 name: "ChatBos",
 data() {
   return {
     messages: [],
     currentMessage: null
   }
 },

 methods: {
   async sendMessage(message) {
     this.messages.push({
       from: 'user',
       data: message
     })
     await axios.post('http://localhost:3000/ask-to-chat-gpt', {
       message: message
     })
     .then((response) => {
       this.messages.push(response.data)
     })
   }
 }
};
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
input {
 width: 300px;
 padding: 10px;
}

button {
 height: 40px;
 background-color: powderblue;
 padding: 10px;
}
.messageBox {
 height: 500px;
 background-color: gainsboro;
 /* margin-left: 10%;
 margin-right: 10%; */
 margin: 0 20% 0 20%;
 margin-top: 20px;
 padding: 5%;
}

.messageFromUser {
 text-align: right;
 background-color: aliceblue;
 border-radius: 10px;
 padding: 10px;
 margin-top: 15px;
 margin-bottom: 15px;
 width: 30%;
 margin-left: 70%;
}

.messageFromChatGpt {
 text-align: left;
 background-color: antiquewhite;
 border-radius: 10px;
 padding: 10px;
 margin-top: 15px;
 margin-bottom: 15px;
 width: 30%;
 margin-right: 70%;
}
</style>

Now, the coding part is done, so we will move forward to test it.

Step 4: Test the Flow

Here, we have served the backend on http://localhost:3000 and the Frontend on http://localhost:8080.

For Backend

node  index.js

For Frontend

npm run serve

Now, you will see a ChatGPT input box on the top. Just input a question and you will receive its respective answer from ChatGPT.

So, we have successfully integrated ChatGPT with Node and Vue.

To make the functioning smooth and efficient, understanding the basics of ChatGPT services will be beneficial.

Basic Terminologies of ChatGPT

When we use the ChatGPT services, we can customize our requests by specifying certain properties.

These properties play a vital role in determining the responses we receive from the ChatGPT APIs.

To understand this better, let’s take a closer look at each property and how it influences the answers we get. It’s like unlocking a magical world where our requests shape the outcomes.

await openAIInstance.createCompletion({
    model: 'text-davinci-003',
    prompt: req.body.message,
    temperature: 0,
    max_tokens: 500
})
.then {(response) => {
      const repliedMessage = response.data.choices[0].text
      res.send({from: 'chatGpt', data: repliedMessage})
})
.catch( (error) => {
    //Report error
    console. log('Error ', error)
});

Model

Here, we have used the ‘text-davinci-003’ model. As we know, ChatGPT is trained with huge data sets, you can choose which model to use while making the request, depending on your use case as well.

Prompt

The prompt is the question that we have to ask ChatGPT. In our project, it is a message requested from the client side.

Temperature

Temperature determines the diversity of answers you receive, allowing you to choose the level of variation that suits your needs. Lower values below 1.0 offer more predictable responses, while higher values offer more imaginative and diverse outcomes.

Max_Tokens

It directly decides the length of the answers and defines the number of words, punctuation marks, etc.

Conclusion

Integrating ChatGPT with Node and Vue brings exciting opportunities for developers and bloggers.

This combination allows us to create interactive chat interfaces that utilize the power of natural language processing and the user-friendly features of Vue.

Through this, we can enhance customer support, build intelligent chatbots, and craft immersive storytelling experiences that captivate our audience.

Step 1: Create a New Angular App

Start by creating a new Angular app using the following command.

ng new my-new-app

Step 2: Installing Bootstrap

This step guides you on how to install Bootstrap 4 in your Angular app using npm. Additionally, you need to add the Bootstrap CSS file to the angular.json file.

npm install bootstrap

Now you need to add bootstrap css in the angular.json file.

angular.json

....
"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
        ],
....

Step 3: Creating a Service

This step involves creating a service called ImageUploadService to handle the image upload functionality. The service utilizes the HttpClient module to make HTTP requests to the server.

The imageUpload method sends a POST request with the image file and progress tracking enabled. The errorMgmt method handles any errors that occur during the upload process.

ng generate service image-upload

src/app/image-upload.service.ts

import { Injectable } from '@angular/core';
import { Observable, throwError } from 'rxjs';
import { catchError } from 'rxjs/operators';
import { HttpErrorResponse, HttpClient } from '@angular/common/http';
  
@Injectable({
  providedIn: 'root'
})
export class ImageUploadService {
  
  constructor(private http: HttpClient) { }
  
  imageUpload(name: string, profileImage: File): Observable {
var formData: any = new FormData();
    formData.append("name", name);
    formData.append("image", profileImage);
  
    return this.http.post('http://localhost:8000/upload.php', formData, {
      reportProgress: true,
      observe: 'events'
    }).pipe(
      catchError(this.errorMgmt)
    )
  }
  
  errorMgmt(error: HttpErrorResponse) {
    let errorMessage = '';
    if (error.error instanceof ErrorEvent) {
      // Get client-side error
      errorMessage = error.error.message;
    } else {
      // Get server-side error
      errorMessage = `Error Code: ${error.status}\nMessage: ${error.message}`;
      console.log(error);
    }
    console.log(errorMessage);
    return throwError(errorMessage);
  }
}

Step 4: Importing Modules

In this step, you import the necessary modules (HttpClientModule and ReactiveFormsModule) and the ImageUploadService into the AppModule.

src/app/app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
  
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { ReactiveFormsModule } from '@angular/forms';
  
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule,
    ReactiveFormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 5: Updating the View File

Here, you update the app.component.html file to include a form with file input and a progress bar.

src/app/app.component.html

<div class="row">
<div class="col-md-8">
<div class="container mt-5">
	<div class="card">
		<div class="card-header">
			<strong>How To Image Upload With Progress Bar Angular 15 - Websolutionstuff</strong>
		</div>
		<div class="card-body">
			<form [formGroup]="form" (ngSubmit)="submitImage()">
				<!-- Progress Bar -->
				<div class="progress form-group mb-2" *ngIf="progress > 0">
					<div class="progress-bar progress-bar-striped bg-success" role="progressbar" [style.width.%]="progress">{{progress}}%
					</div>
				</div>
<div class="form-group">
     <input formControlName="file" type="file" class="form-control" (change)="uploadFile($event)">
    </div>
    
    <div class="form-group">
     <button class="btn btn-success btn-block mt-2">Submit</button>
    </div>
   </form>
  </div>
 </div> 
</div>
</div>
</div>

Step 6: Using the Component TypeScript File

In the app.component.ts file, you define the form, progress variable, and necessary methods. The uploadFile method updates the form with the selected image file.

The submitImage method calls the imageUpload method from the service and subscribes to the progress events. Depending on the event type, progress updates and completion messages are logged.

src/app/app.component.ts

import { Component } from '@angular/core';
import { FormBuilder, FormGroup } from "@angular/forms";
import { ImageUploadService } from "./image-upload.service";
import { HttpEvent, HttpEventType } from '@angular/common/http';
   
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  form: FormGroup;
  progress: number = 0;
  
  constructor(
    public fb: FormBuilder,
    public imageUploadService: ImageUploadService
  ) {
    this.form = this.fb.group({
      name: [''],
      avatar: [null]
    })
  }
  
  ngOnInit() { }
  
  uploadFile(event:any) {
    const file = event.target.files ? event.target.files[0] : '';
    this.form.patchValue({
      avatar: file
    });
    this.form.get('avatar')?.updateValueAndValidity()
  }
  
  submitImage() {
    this.imageUploadService.imageUpload(
      this.form.value.name,
      this.form.value.avatar
    ).subscribe((event: HttpEvent<any>) => {
      switch (event.type) {
        case HttpEventType.Sent:
          console.log('Request has been made!');
          break;
        case HttpEventType.ResponseHeader:
          console.log('Response header has been received!');
          break;
        case HttpEventType.UploadProgress:
          var eventTotal = event.total ? event.total : 0;
          this.progress = Math.round(event.loaded / eventTotal * 100);
          console.log(`Uploaded! ${this.progress}%`);
          break;
        case HttpEventType.Response:
          console.log('Image Upload Successfully!', event.body);
          setTimeout(() => {
            this.progress = 0;
          }, 2000);
  
      }
    })
  }
}

Step 7: Creating a PHP API

In this step, we will create a PHP file called upload.php that takes care of the server-side logic for uploading images.

This file will be responsible for receiving the image file from the client and moving it to the desired location on the server.

Additionally, it will provide a JSON response back to the client, indicating whether the upload was successful or not.

Now that we have successfully implemented the image upload functionality, including the preview feature, in our Angular application, it’s time to create an API file using PHP.

This API file, upload.php, will handle the actual process of receiving the uploaded image file and storing it in a specific folder called “upload”.

By creating the upload.php file, we will have a centralized component that handles the communication between the client-side Angular application and the server-side storage.

This ensures a smooth and efficient process for uploading and storing images in our application

upload.php

<?php
  
    header("Access-Control-Allow-Origin: *");
  
    header("Access-Control-Allow-Methods: PUT, GET, POST");
  
    header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
  
    $target_dir = "upload/";
    $target_file = $target_dir . basename($_FILES["image"]["name"]);
    $uploadOk = 1;
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
  
    if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
        $t = "The file ". htmlspecialchars( basename( $_FILES["fileToUpload"]["name"])). " has been uploaded.";
    } else {
        $t = "Sorry, there was an error uploading your file.";
    } 
  
    header('Content-Type: application/json; charset=utf-8');
    echo json_encode([$t]);
    exit;
  
?>

Step 8: Test the Image Upload with Progress Bar

Start the Angular development server using the ng serve command and open the app in your browser. Try selecting an image file using the file input field. The selected image should be displayed in the preview area.

ng serve

To run the PHP file on a different port, you can use a PHP development server. Open your terminal or command prompt, navigate to the directory where the upload.php file is located, and run the following command.

php -S localhost:8000
