Underscore.js (tested with 1.1.7)

JSON_Minifier minifies a JSON array of Objects. Its motivation is to reduce the bandwidth of JSON Web Services. See arwid.github.com/JSON_Minifier for an example which reduces a simple JSON by 50%.

Usage

Use _.JSON_minify to minify a JSONString or JSONObject and _.JSON_revert to revert it back to original.

minified = _.JSON_minify([{ "firstName": "John" , "lastName": "Doe"   , "age": 23 }])
reverted = _.JSON_revert(minified)

As a very simple example, the following JSON

[
  { "firstName": "John" , "lastName": "Doe"   , "age": 23 },
  { "firstName": "Mary" , "lastName": "Smirth", "age": 32 },
  { "firstName": "Sally", "lastName": "Green" , "age": 27 },
  { "firstName": "Jim"  , "lastName": "Galley", "age": 41 }
]

…reduces to

{
  "data": [["John","Doe",23],["Mary","Smirth",32],["Sally","Green",27],["Jim","Galley",41]],
  "map" : ["firstName","lastName","age"]
}

Todos

  • Add support for more complicated JSONs. A mapping could possibly look like this:

    "map" : {"name":"[0]","address":"[1]","postalCode":"[1][0]","city":[1][1]"}

  • Extend api.jquery.com/jQuery.ajax/ by offering 'jsonm' as a datatype.

  • Create a ruby gem
