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 ' ) ; } ) ;
