JSON parser that isn't strict

jsonic

A JSON parser for Node.js that isn't strict.

A JSON parser that can parse "bad" JSON. Mostly, this is about avoiding the need to quote everything!

Strict JSON requires you to do this:

{ "foo":"bar", "red":1 }

The JavaScript language itself is a little easier:

{ foo:"bar", red:1, }

But if you really want to be lazy, jsonic lets you say:

foo:bar, red:1,

See below for the relaxed JSON rules.

This module is used by the Seneca framework to provide an abbreviated command syntax.

Support

Current Version: 0.1.1

Tested on: node 0.10.19, Chrome 29

Quick example

var jsonic = require('jsonic')

// parse a string into a JavaScript object
var obj = jsonic('foo:1, bar:zed')

// prints { foo: '1', bar: 'zed' }
console.dir( obj )

Install

npm install jsonic

Relaxed Rules

JSONIC format is just standard JSON, with a few rule relaxations:

• You don't need to quote property names: { foo:"bar baz", red:255 }
• You don't need the top level braces: foo:"bar baz", red:255
• You don't need to quote strings with spaces: foo:bar baz, red:255
• You do need to quote strings if they contain a comma or closing brace: icky:",}_"
• You can use single quotes for strings: Jules:'Cry "Havoc," and let slip the dogs of war!'
• You can have trailing commas: foo:bar, red:255,

How it Works

The parser uses PEG.js and is an extension of the example JSON parser included in that project.

Development

You'll need:

sudo npm install [email protected] uglify-js -g
