Introspected NPM

Introspected

If you'd like to be notified about any possible change that could happen to a JSON compatible model / data / object / array / structure, including the possibility to retrieve the exact full path of the object that changed and eventually walk through it, you've reached your destination.

const data = Introspected(
  // any object or JSON compatible structure
  // even with nested properties, objects, arrays
  JSON.parse('{}'),
  (root, path) => {
    // the root object that changed
    console.log(root);
    // the path that just changed
    console.log(path);
  }
);

// now try the following in console
data.a.b.c.d.e.f.g = 'whatever';
data.array.value = [1, 2, 3];
data.array.value.push(4);
// see all notifications about all changes 🎉

JSON.stringify(data);
// {"a":{"b":{"c":{"d":{"e":{"f":{"g":"whatever"}}}}}},"array":{"value":[1,2,3,4]}}
