Eviluation

This library uses ES6 templates - node > 4.0 is required.

Stringify javascript objects, function or prototypes and get them back. This can be dangerous if misused!

For example, take this prototype:

function Test() {}

Test.prototype.hello = function(name) {
  return `hello ${name}!`
}

Now we can share this as a string:

var engine = require('eviluation')

var str = engine.stringify(Test)

var SomeTest = engine.parse(str)

var t = new SomeTest()

//prints hello you!
console.log(t.hello('you'))

Internally this only uses new Function(string), so it will run in the global context. This can obviously be harmful:

 var t = function() {
  //do some evil things with global variables
  return process
 }

 var s = engine.stringify(t)
 var o = engine.parse(s)
 
 expect(o()).to.deep.equal(process)

Anyway, having an Error object stringified can be useful:

var t = new Error('test')

var s = engine.stringify(t)

var o = engine.parse(s)

console.log(o.stack)
