Programming with ChatGPT4 – Creating the Genre Viewer in Express.JS

If you’re a developer looking to integrate ChatGPT4 into your web application, you might be wondering how to create a genre viewer using Express.JS. In this article, we’ll walk you through the steps to build a simple genre viewer using Express.JS and ChatGPT4.

Setting up your project

First, make sure you have Node.js installed on your system. Then, create a new directory for your project and navigate to it in your terminal. To initialize a new Node.js project, run the following command:

npm init -y

Installing dependencies

Next, you’ll need to install the required dependencies for your project. Run the following command to install Express and the OpenAI API client:

npm install express openai

Creating the Express server

Now that you have your project setup and dependencies installed, you can create the Express server. Create a new file called index.js and add the following code:

const express = require('express');
const openai = require('openai');
const app = express();
const gpt = new openai.ChatCompletion({
  engine: "text-davinci-003",
  apiKey: "YOUR_API_KEY"
});

app.get('/genre-viewer', async (req, res) => {
  const genre = req.query.genre;
  const prompt = `I want to read a ${genre} book. Can you suggest some good ones for me?`;
  const completion = await gpt.createChatCompletion(prompt);
  const suggestions = completion.choices[0].text.trim();
  res.send(suggestions);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Replace YOUR_API_KEY with your actual OpenAI API key. This code sets up a basic Express server with a route to handle genre requests and generate book suggestions using ChatGPT4.

Testing the genre viewer

Start your Express server by running the following command in your terminal:

node index.js

Now, you can test the genre viewer by visiting http://localhost:3000/genre-viewer?genre=mystery in your web browser. This will return book suggestions for the mystery genre. You can replace mystery with any other genre to get suggestions for that genre.

Next steps

This is just a simple example of how you can integrate ChatGPT4 into your web application using Express.JS. You can further customize the genre viewer, add frontend components, and enhance the user experience. Additionally, you might want to handle error cases and improve the performance of your server.

Now that you have a basic understanding of how to create a genre viewer using Express.JS and ChatGPT4, you can start building more complex and interactive applications that leverage the power of natural language processing.

Happy coding!
