Immutablejs

[pablohpsilva]

First things first: I loved this lib!

Is there a way to add ImmutableJS into dot-object lib? I think it would be cool and would enhance the performance.

That would become a different library I think, dot-object is mutating everything in-place.

What methods / functions would like to use along side with ImmutableJS?

I see... I thought it was mutating the source element into something else, that's why I opened this issue to see if you could use ImmutableJS in this lib advantage.

I read the move and set functions and now I get what the lib's doing.

It might be a crazy idea, but... I think dot-object can use it. Since it is creating a new object, it could create a immutable one. How? The main idea would be:

const obj = {
  'first_name': 'John',
  'last_name': 'Doe'
};

const attributeList = [
  'from|to',
  'first_name|contact.firstname',
  'last_name|contact.lastname'
];

const immutableObj = dot.move(attributeList, obj);

Then, the move function would be something that uses the Immutable.Map, for example, and would return a immutable object as result;

export const move = (attributeList, obj) => {
  const aux = (Iterable.isIterable(obj)) ? obj : Immutable.Map(obj);
  const nObject = ... // apply attributeList `aux` to create nObject;
  return Immutable.Map(nObject);
};

That function could check if the obj is already a ImmutableJS obj and take advantage on delete, set, get, merge, and some other cool functions provided by ImmutableJS itself.
