Node-Lepton

A NodeJS wrapper library for Dropbox JPEG Letpon compression tool.

Quick start

This guide assumes you have Dropbox Lepton and node/npm already installed.

First, run npm install node-lepton --save for your app. Then, in an Express app:

var lepton = require('node-lepton');

// ...

After this you can run one of two commands, compress or decompress. You must provide a valid path for either of these functions to work.

These functions takes a callback that returns an error object and the output in form of a binary file blob.

lepton.compress('../../aoeu.jpeg',  
{
  unjailed: true,
},
function(err, data){
  if(err) throw err;
  
  console.log('Successfully compressed aoeu.jpeg');
});

lepton.decompress('../../aoeu.lep', 
{
  unjailed: true,
},
function(err, data){
  if(err) throw err;
  
  console.log('Successfully decompressed aoeu.lep');
});
