Javascript app: require is not defined

Question

I have an array and I want to create a .json to store the array in it. This is what I have, but i receive require is not defined. I know it has something to do with NodeJS, but I dont know what I should do.

let answersString = JSON.stringify(answersArray);
const fs = require('fs');

fs.writeFileSync("answers.json", answersString);

Thanks!

EDIT: Now I know this was a pretty dumb question, sorry. In the meantime I learned about node, bundling, testing etc.

Is this to do with RequireJS, which is a browser framework? Node.JS runs server-side, not in the browser... — cmbuckley, Feb 27 '18 at 11:55

You're using the code in client, and require() does not exists in javascript browser-side (nodeJS is server side...).

My proposal would be to send file to server side where you will have fs and do the work there.

Thanks for the quick answer. And how should I create the .json file? – Ezeeroc Feb 27 '18 at 11:57

You still can use require at the client side but you need to use a bundler. The notorious ones are Webpack and Browserify.
