Create a Domain Name Generator with OpenAI GPT-4o & Real-time Availability Check | Full Walkthrough

People & Blogs

Introduction

In this comprehensive tutorial, we will build a simple full-stack web application that integrates OpenAI's powerful API to develop an AI-based domain name generator. This application will not only generate domain name suggestions but also check their availability in real time. Whether you are a beginner exploring AI integration or an experienced developer looking to streamline your process, this guide will provide you step-by-step instructions to create a fully functional web app capable of tapping into AI capabilities.

Project Overview

The application we will be building is called Dominator, an AI-powered domain name generator. By the end of this tutorial, you will have a solid foundation that you can expand for your own projects.

We will cover:

  • Setting up the development environment
  • Creating a front-end user interface using HTML and Bootstrap
  • Setting up a back-end service with Node.js and Express
  • Integrating real-time checks for domain name availability
  • Utilizing OpenAI's API for generating domain names

Setting Up the Environment

  1. Create Project Folder: Start by creating a folder named "Dominator" for our project. Open this folder in your preferred code editor (e.g., Visual Studio Code).

  2. Initialize a Git Repository: Use Git to initialize your project and store it on GitHub. You will be able to access all code in the repository linked in the description.

  3. Set Up Node.js: Initialize a Node.js application using the command:

    npm init -y

  4. Install Required Packages: We will install several packages to facilitate our development:

    • Express: For the back-end server.
    • CORS: To enable communication between the front-end and back-end.
    • Dotenv: To manage environment variables securely.
    • OpenAI: For integrating the OpenAI API.
    • Whoiser: To check domain name availability.

  5. Create Project Structure: Set up an index.js file for the server logic and an index.html file for the user interface.

Creating the User Interface

  1. HTML Structure: Create a simple HTML page using Bootstrap 5 that contains:

    • A title prompting the user to describe their desired domain name.
    • A text area where users can input their text.
    • A submit button to send the input to the back-end.
    • A container to display responses after submission.

  2. JavaScript for Form Functionality: Write a JavaScript function to handle the form submission. The function should listen for the submit event, send the content of the text area to the back-end, and then display the returned results in the response container.

Setting Up the Back End with Node.js and Express

  1. Basic Express Server: Using OpenAI's API, create a basic Express server with a POST route that handles incoming requests.

  2. OpenAI API Setup:

    • Create a project on OpenAI and configure it for our application.
    • Generate an API key and store it securely using environment variables in a .env file.

  3. Handling API Requests: Set up the server to receive the domain description, forward it to OpenAI to generate domain name suggestions, and return the results to the front end.

  4. Integrate Availability Checks: Use the Whoiser library to check whether the generated domain names are available for registration, and then return this information alongside the suggestions.

Final Touches

  1. Display Results on the Front End: Modify the JavaScript to display the results in a structured table format, indicating whether each domain is available or taken.

  2. Styling: Ensure the table and its content are styled for better user experience.

  3. Testing the Application: Test the application by generating domain names for different business ideas and check the availability to ensure everything works as expected.

Conclusion

By the end of this tutorial, you will have a complete AI-powered domain name generator capable of suggesting creative domain names and checking their availability instantly. There are further improvements and functionalities you can add, such as allowing users to navigate suffix options or customizing character limits.
