Interacting with ChatGPT API in Angular Application

ChatGPT is a powerful API that allows developers to integrate chat functionality into their applications. In this article, we will explore how to interact with the ChatGPT API in an Angular application.

Step 1: Obtaining API Key

In order to use the ChatGPT API, you will need to obtain an API key. You can do this by signing up for an account on the ChatGPT website and generating a new API key.

Step 2: Setting Up Angular Project

To begin, create a new Angular project using the Angular CLI:

  
  npm install -g @angular/cli
  ng new chatgpt-angular
  cd chatgpt-angular

Step 3: Installing Axios Library

We will be using the Axios library to make HTTP requests to the ChatGPT API. Install Axios by running the following command:

  
  npm install axios

Step 4: Interacting with ChatGPT API

Now that our project is set up, we can start interacting with the ChatGPT API. Create a new service in Angular to handle the API requests. Here’s an example of a chat service that makes a request to the ChatGPT API:

  
  import { Injectable } from '@angular/core';
  import axios from 'axios';

  @Injectable({
    providedIn: 'root'
  })
  export class ChatService {

    private apiUrl = 'https://api.openai.com/v1/engines/davinci-codex/completions';

    constructor() { }

    sendMessage(message: string) {
      const headers = {
        'Authorization': 'Bearer YOUR_API_KEY',
        'Content-Type': 'application/json'
      };

      return axios.post(this.apiUrl, {
        prompt: message,
        max_tokens: 150
      }, { headers });
    }
  }

Step 5: Using the Chat Service in Angular Components

Now that we have a chat service set up, we can use it in Angular components to interact with the ChatGPT API. Here’s an example of how to use the chat service in a component:

  
  import { Component } from '@angular/core';
  import { ChatService } from './chat.service';

  @Component({
    selector: 'app-chat',
    templateUrl: './chat.component.html',
    styleUrls: ['./chat.component.css']
  })
  export class ChatComponent {

    constructor(private chatService: ChatService) { }

    sendMessage(message: string) {
      this.chatService.sendMessage(message)
        .then(response => {
          console.log(response.data.choices[0].text);
        })
        .catch(error => {
          console.error(error);
        });
    }
  }

With these steps, you can start interacting with the ChatGPT API in your Angular application. This will allow you to build powerful chat functionality into your application using the capabilities of the ChatGPT API.
