#ai #node #tutorial #beginners

Hello

Did you try AI for real in your projects?
Specifically OpenAI API or just announeced Vertex from Google?

Here we are.
We will create a product generator for your next marketplace solution!

Create a new project
Init npm init es6
Install open AI package npm install openai
Create a file index.js
Add this code

import { Configuration, OpenAIApi } from "openai";

const configuration = new Configuration({
  apiKey: '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' 
// Input Your Open AI key here from
// https://platform.openai.com/account/api-keys
});
const openai = new OpenAIApi(configuration);

async function getImage(info) {
  const response = await openai.createImage({
    prompt: info,
    n: 1,
    size: "256x256"
  });

  return response.data.data[0].url;
}

async function getProductInfo(info) {
  const completion = await openai.createChatCompletion({
    model: 'gpt-3.5-turbo',
    messages: [{ "role": "user", "content": `Generate a creative info in JSON for product type ${info}, use following structure  "{name: string, price: string, currency: string }", respond only with JSON` }]
  });

  const output = completion.data.choices[0].message.content;
  return JSON.parse(output);
}

function getProduct(info) {
  const productInfo$ = getProductInfo(info);
  const image$ = getImage(info);
  return Promise.all([productInfo$, image$]).then(([product, image]) => ({ ...product, imageUrl: image }));
}

async function execute() {
   const topic = 'Kid Toy';
   const productNumbers = 4;

   const promises = [];
   for (let i = 0; i < productNumbers; ++i) {
     promises.push(getProduct(topic))
   }

   const products = await Promise.all(promises);

   console.log(products);
}

execute();

6) Execute the file node index.js
7) Check terminal or console, you would see the following

Can you imagine? you just generated quite real products, it could be anything else. Be creative - test it out.
