JZON

A simple wrapper for JSON functions to return errors instead of throw

Introduction

I tend to use a lot of JSON in my apps, but I dislike the common method of wrapping JSON calls in a try/catch block. It can get very repetetive for such a common task, so instead of writing:

try{
  var x = JSON.parse(str);
catch(e){
  //error handling bits here
}

I would rather write:

  var x = jzon.parse(str);

Then the code handling x should be able to determine whether it received an error or the parsed value.

Installation

npm install jzon

Usage

JZON can function as a drop-in replacement for the native JSON libraries.

var jzon = require('jzon');
jzon.parse(str);
jzon.stringify(obj);

Also, the jzon variable itself is a function which you can use like so:

var x = jzon('parse', str);
var y = jzon('stringify', obj);

And, if you like callback style, the last argument can be a callback.

jzon.parse(str, function(err, obj){
  if(err) return
})
