object-fill-missing-keys

Add missing keys into plain objects, according to a reference object

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required:

npm i object-fill-missing-keys

If you need a legacy version which works with require, use version 8.1.0

Quick Take

import { strict as assert } from "assert";
import { fillMissing } from "object-fill-missing-keys";

// deleting key 'c', with value 'd'
assert.deepEqual(
  fillMissing(
    {
      // input object that could have came from JSON
      b: "b",
    },
    {
      // schema reference object
      a: false,
      b: false,
      c: false,
    }
  ),
  {
    // patched result
    a: false,
    b: "b",
    c: false,
  }
);
