AI (ChatGPT) Implementation Guide

You can select your AI tool of choice, we will demonstrate how to integrate the ChatGPT API into a real estate application using Nest.js. This integration will enable features like virtual assistants, personalized property recommendations, and automated content creation.

In our demonstration, we will use TS and NodeJS for the backend with Nest.js as the framework.

1.Setup project and install required dependencies

npm i -g @nestjs/cli

nest new gpt-implementation

npm install --save axios @nestjs/common @nestjs/core @nestjs/config reflect-metadata rxjs

2.In the/scr folder, create gpt directory

Required structure:





        │   chatgpt.module.ts

        │   chatgpt.service.ts

        │   chatgpt.controller.ts

3.Create 3 files in chatgpt folder as we have in the structure example.

  • chatgpt.module.ts
  • chatgpt.service.ts
  • chatgpt.controller.ts

4.Add code to chatgpt.module.ts

import { Module} from '@nestjs/common';
import { ChatGPTService } from './chatgpt.service';
import { ChatGPTController } from './chatgpt.controller';
import { HttpModule } from '@nestjs/axios';

 imports: [HttpModule],
 providers: [ChatGPTService],
 controllers: [ChatGPTController],
 exports: [ChatGPTService],
export class ChatGPTModule {}

import { HttpModule } from ‘@nestjs/axios’; We import the HttpModule from the @nestjs/axios package. The HttpModule provides utilities for making HTTP requests.
imports: [HttpModule] imports the HttpModule, which provides HTTP request functionalities.
providers: [ChatGPTService] This property specifies the providers (services) that are instantiated by this module, and that may be shared at least across this module. Here, it includes ChatGPTService, making it available throughout the module.
controllers: [ChatGPTController] controllers handle incoming requests and return responses.
exports: [ChatGPTService] we exported ChatGPTService so other modules can use it.

5.Create a .env file in the root folder and add the following line there


6.Add code to chatgpt.service.ts

import { Injectable} from '@nestjs/common';
import { AxiosResponse } from 'axios';
import { Observable } from 'rxjs';
import { HttpService } from '@nestjs/axios';

export class ChatGPTService {
 private readonly apiKey: string;
 private readonly apiUrl: string;

 constructor(private readonly httpService: HttpService) {
   this.apiKey = process.env.CHATGPT_KEY;
   this.apiUrl = '';

 generateResponse(prompt: string): Observable<AxiosResponse> {
   const data = {
     prompt: prompt,
     max_tokens: 150,
     n: 1,
     stop: null,
     temperature: 1,

   const headers = {
     'Content-Type': 'application/json',
     'Authorization': `Bearer ${this.apiKey}`,

   return, data, { headers: headers });

This service provides a method generateResponse that takes a prompt as input and returns an observable representation of the response from the OpenAI API.

API call options:

  • Prompt input prompt for the ChatGPT model.
  • max_tokens: 150 This sets the maximum number of tokens (the model is allowed to generate in its response. In this case, it’s set to 150.
  • n: 1 This sets the number of completions to generate for each prompt. It’s set to 1, meaning the model will generate one completion/response.
  • stop: null This parameter indicates a stop sequence for model generation. If set to a string or an array of strings, the model will stop generating tokens once it encounters any of these sequences. It’s set to null in this case, meaning the model won’t stop based on any specific sequence.
  • temperature: 1 This parameter controls the randomness of the generated response. A lower temperature makes the model more conservative and likely to generate more common responses, while a higher temperature makes it more creative and likely to generate diverse responses. Here, it’s set to 1, indicating a moderate level of randomness.

7.Add code to chatgpt.controller.ts

import { Controller, Post, Body, HttpCode, HttpStatus } from '@nestjs/common';
import { ChatGPTService } from './chatgpt.service';
import { AxiosResponse } from 'axios';
import { map } from 'rxjs/operators';

export class ChatGPTController {
 constructor(private readonly chatGPTService: ChatGPTService) {}

 generateResponse(@Body('prompt') prompt: string) {
   return this.chatGPTService
     .pipe(map((response: AxiosResponse) =>[0].text.trim()));

ChatGPTController handles incoming HTTP requests related to the ChatGPT functionality.
The pipe operator transforms the emitted value from the observable.

8.Modify the app module in the/src folder

import { Module } from '@nestjs/common';
import { ChatGPTModule } from './chatgpt/chatgpt.module';

 imports: [ChatGPTModule],
export class AppModule {}

This is how you can implement ChatGPT for your application and combine it with your preferred Real Estate API.
