Like if you want that Gemini return the solution in JSON then you have to type
Give me the top 10 news in new york, USA. Format the response and return in JSON
So her basically you are giving command then give the top 10 news in JSON. then Gemini will do this for you.
Here is the image you can check.
and If you are working with node js then you have to use one package name that is
npm i @google/generative-ai
This is an official package by google in node js
You can create function like
const generateAiResponse = () => {
if (!process.env.GEMINI_AI_API_KEY) {
console.error('GENERATIVE_AI_API_KEY is not defined');
return;
}
const genAI = new GoogleGenerativeAI(process.env.GEMINI_AI_API_KEY);
// add the model of gemini which you wan to use
const model = genAI.getGenerativeModel({ model: "gemini-1.5-flash" });
const result = await model.generateContent(prompt);
const responseText = await result.response.text();
console.log("Parsed JSON Response:", responseText);
return responseText;
