Notes

I'm a mediocre developer hacking away at hard problems. Whenever I figure something out, I write a note to myself so when I inevitably have the same problem in the future, I'll have a reference.

I've been doing this for years, locally, but just recently started pushing notes to a repo.

cryo's Issues

Prototype functions

Does it work with functions defined on an object's prototype? At a first look it doesn't seem so.

RangeError: Maximum call stack size exceeded

I am trying to stringify objects slightly larger than the example object that I have posted. And I receive the following error.

Error:

RangeError: Maximum call stack size exceeded

Objects of a given class

As it stands, cryo can re-create objects, but recreates vanilla objects, not those of their original type.

Would you be open to a pull request that added functionality so that something like this would be possible:

function Shape() {
  this.x = 0;
  this.y = 0;
}

var shape = new Shape();
var cryoShape = Cryo.parse(Cryo.stringify(shape));

shape instanceof Shape; // true
cryoShape instanceof Shape; // true

It would likely use __proto__ and/or setPrototypeOf and may require a way for types to be found during Cryo.parse.

Does this support outputting a string equivalent (compatible) with pickle.dumps ?

I need a javascript pickler (or json to pickled string utility) that outputs strings equivalent to what pickle.dumps would provide.

Is that feasible?

If not could you give some programming pointers for me to endeavour in writing?

status of this project?

Looks like the last commit was in 2017. Is this project still maintained or should it be considered EOL? @hunterloftis
Also, I couldn't find a license listed for your project. Can you make one publicly available?

Cryo.parse(Cryo.stringify(Cryo)) fails

Cryo.parse(Cryo.stringify(Cryo)) throws a SyntaxError on Chrome 23.0.1271.101/Mac 10.7.5.

Example output of stringify?

Looked through most of the tests, examples, and docs and still can't find an example of what the output looks like.

Security issue

Hi,

I'm a member of the Node.js Security WG and we received a report regarding a security issue with this module. We tried inviting the author by e-mail but received no response so I'm opening this issue and inviting anyone with commit and npm publish rights to collaborate with us on a fix.

Support ES6 Class

I was just wondering if anyone has looked into adding this before and not done it for any reason, and if not, @hunterloftis would you accept a PR to add this?

Support ES6 Map and Set

Certainly these can be done in a custom way, but it would be nice to support these structures by default, since they are often used.
