OpenAI API Tutorial: Getting Started with Node.js Integration

steps

1. Create a new folder for your project and navigate into it:

   bashCopy

   mkdir openai-node-integration
   cd openai-node-integration

2. Initialize a new Node.js project:

   bashCopy

   npm init -y

   This command generates a package.json file with default settings.

3. Create an entry file for your application (e.g., app.js):

   bashCopy

   touch app.js

4. Add a quick test to verify the setup. Open app.js in your code editor and insert the following:

   javascriptCopy

   console.log("Node.js project initialized");

5. Run your application to ensure it works:

   bashCopy

   node app.js
   # Output: Node.js project initialized

steps

1. Create a configuration folder and file:

   bashCopy

   mkdir config
   touch config/openaiConfig.js

2. Inside config/openaiConfig.js, set up the configuration:

   javascriptCopy

   import { Configuration, OpenAIApi } from "openai";
   
   // Initialize OpenAI configuration
   const configuration = new Configuration({
       apiKey: "your_api_key_here",
   });
   
   // Create an OpenAI client
   const openai = new OpenAIApi(configuration);
   
   export default openai;

3. Create a .env file in the project root and add your OpenAI API key:

   bashCopy

   touch .env

   Inside .env:

   Copy

   OPENAI_API_KEY=your_api_key_here

4. Update your app.js file to:

   javascriptCopy

   import openai from './config/openaiConfig.js';
   
   (async () => {
       console.log("Verifying OpenAI connection...");
       try {
           const response = await openai.listModels();
           console.log("Available models:", response.data);
       } catch (error) {
           console.error("Error connecting to OpenAI:", error.message);
       }
   })();

5. To enable ES modules, add "type": "module" in your package.json:

   jsonCopy

   {
     "name": "openai-node-integration",
     "version": "1.0.0",
     "type": "module",
     ...
   }

6. Run your application:

   bashCopy

   node app.js
   # Output will list available models or display an error message.
