node-json-minifier

A two-way JSON minifier to reduce JSON size and amount of data transferred on clients. Can also act as an obfuscator.

how to use

npm install json-minifier

Compressor

var specs = {
  key: 'k',
  MySuperLongKey: 'm',
  SomeAnotherPropertyThatIsRealyLong: 's'
};

var minifier = require('json-minifier')(specs);

var json = minifier.minify({
  SomeAnotherPropertyThatIsRealyLong: 1234,
  MySuperLongKey: 'Home',
  key: 0
});

/*
{ s: 1234,
  m: 'Home',
  k: 0 } 
*/
console.log(json);

Uncompressor

Using the json object from the previous exemple:

/*
{
  SomeAnotherPropertyThatIsRealyLong: 1234,
  MySuperLongKey: 'Home',
  key: 0
}
*/
console.log(minifier.unminify(json));

Use in browser

You can implement your own, don't need to require our module or use browserify. Use the following snippet:

json is your compressed json, and you exposed your compression table in the reverseJsonFilters array.

function unzip(json) {
  for (var key in json) {
    if (typeof json[key] === 'object') {
      unzip(json[key]);
    } 
    if (reverseJsonFilters[key] !== undefined) {
      json[reverseJsonFilters[key]] = json[key];
      delete json[key];
    }
  }
}
