How to transfer data from node.js array to js array?

Question

JavaScript

The task is this: I receive data from the database that I process with node.js, put it into an array, and I need to transfer it to the array in which it is located in the js file. Or put node js data into a file and from there somehow read it into the js array. Can this be done somehow using the local server that I created on node.js?

Answer 1

Well, you need your nodejs to set up a web server on some port and return json in the response. In js which in the browser you make a request to your host.

async function getData() {
  const response = await fetch("https:://node-js-host/get");
  const json = await response.json();
}

1. You can create your own API based on Express, for example, which will give the necessary data when requested.
2. If the data is updated infrequently and you know about it - you can save the array as a JSON object to a file and access it from JavaScript.
The bottom line is that you must contact the backend for this array from the frontend.
