Google's Gemini for Nodejs results in error ReferenceError: fetch is not defined

Question

I am trying Google's Gemini model in Node js as suggested in their documentation here

However, when I executed their sample code in my node application, i receive the following error:

ReferenceError: fetch is not defined

This is the code block i'm trying:

const model = genAI.getGenerativeModel({ model: "gemini-pro"});
const prompt = "Write a story about a magic backpack."
const result = await model.generateContent(prompt);
const response = await result.response;
const text = response.text();
console.log(text);

Anyone know how the issue?

Followed exactly what the documentation example

What's your node version? fetch required node 18 stackoverflow.com/questions/48433783/… — Omkar76

I am using Node 16. However, I installed node-fetch, which still resulted in the same error. I don't see anywhere in Google's documentation that I'd need node 18 in order to use @google/generative-ai — rawPotato

If you're using a version of Node prior to 18, the fetch API is not implemented out-of-the-box and you'll need to use an external module for that, like node-fetch. See this ReferenceError: fetch is not defined — kiranvj
