Optimizing Fetch Requests with a Vanilla JavaScript Debounce Function (No Lodash Required)

Problem: I was working in Node.js and needed to generate a hash from a data object. Instead of relying on external libraries, I decided to use the built-in crypto module to create a simple solution.

Solution: Implemented a small method that uses crypto to generate a SHA-256 hash string from a JavaScript object

import { createHash } from 'crypto';

const hashValue = val =>
  new Promise(resolve =>
    setTimeout(
      () => resolve(createHash('sha256').update(val).digest('hex')),
      0
    )
  );

hashValue(JSON.stringify({ a: 'a', b: [1, 2, 3, 4], foo: { c: 'bar' } })).then(
  console.log
);
// '04aa106279f5977f59f9067fa9712afc4aedc6f5862a8defc34552d8c7206393'

Keywords: Node.js crypto hashing, create hash from object, JavaScript SHA-256, object to hash, hashify data, crypto module, generate hash in Node.js.
