JSON.stringify function

Question

I have an object that has some properties and methods, like so:

{name: \"FirstName\",
age: \"19\",
load: function () {},
uniq: 0.5233059714082628}
         


        

Answer 1

Here's some code I have used in my previous projects, maybe useful?

  // Similar to JSON.stringify(), with three major differences:
  // (1) It also wrap functions
  // (2) Upon execution, it expose an object, nl, into the scope
  // (3) Results are minified by 'uglify-js'
  var bundle = function(obj) {
    var type = typeof obj;
    if(type === 'string') return '\'' + obj + '\'';
    if(type === 'boolean' || type === 'number') return obj;
    if(type === 'function') return obj.toString();
    var ret = [];
    for(var prop in obj) {
      ret.push(prop + ': ' + bundle(obj[prop]));
    }
    return '{' + ret.join(',') + '}';
  };
  var ret = 'var nl = ' + bundle(nl);
  ret = require('uglify-js').minify(ret, {fromString: true}).code;
  fs.writeFileSync('nl.js', ret);

One Caveat when using this is that if the function uses anything in external closure, it won't work, ie: ... obj: {..., key: (function() {...var a = 10;... return function() {... some code uses 'a'...})()}
