Here is a jsfiddle that demonstrates the desired behavior.
import { observable, observe } from 'https://unpkg.com/@nx-js/[email protected]/dist/es.es6.js';
const obj1 = {
name: "My complex object",
subObj: { val: 1 },
}
const obj2= {
name: "Second complex object",
subObj: { val: 2 },
}
const state = observable({
currentObject: null,
});
observe(() => console.log(`${state.currentObject?.name}`));
console.log("Start observing:")
// Should log
state.currentObject = obj1;
// Should log
state.currentObject = obj2;
// Should not log - we only want to observe changes to state.currentObject, but not changes inside state.currentObject.
state.currentObject.name = 'Very complex object';
I imagine an API like:
// Don't observe changes inside `obj1`
state.currentObject = notObservable(obj1);
that does not observe inside obj1.
A trivial implementation would be to have notObservable
add a new property to the object, like __DONT_OBSERVE
and then in observable()
, ignore objects with that property. In the same way that shouldInstrument
is used.
