node-zipfile
Example
var zipfile = require('zipfile');
// Creating a zipfile object
var zf = new zipfile.ZipFile('./test/data/world_merc.zip');
// the zipfile has a list of names:
// zf.names[0] === 'world_merc.prj'
// the zipfile also has a count property that is the number of files contained
// zf.count == 2
// finally it has a readFile method that uncompresses a single file
// into a Buffer object
zf.readFile('world_merc.prj', function(err, buffer) {
if (err) throw err;
console.log(buffer.toString());
});Large files
To handle large zipfiles and avoid the overhead of passing data from C++ to JS use thecopyFile interface:var zipfile = require('zipfile');
var zf = new zipfile.ZipFile('./test/data/world_merc.zip');
var zip_entry_name = 'world_merc.shp';
var output_file = 'out/world_merc.shp';
zf.copyFile(zip_entry_name,output_file, function(err) {
if (err) throw err;
console.log('Successfully wrote ' + output_file);
});Depends

Install from binary:npm installnpm install --build-from-sourceDynamically linking against libzip
node-zipfile depends on libzip, but by default
bundles a copy in deps/ which is statically linked and packaged as a binary.If you want to use an external libzip first install it:
