Bindings to libzip for handling zipfile archives in node.
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()); });To handle large zipfiles and avoid the overhead of passing data from C++ to JS use the copyFile 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); });- Node v0.10.x, v4.x, v5.x, or v6.x
Install from binary:
npm install Install from source:
npm install --build-from-source 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:
Debian:
sudo apt-get install libzip-dev libzip1 OS X:
brew install libzip Then configure node-zipfile with the --shared_libzip option:
npm install --build-from-source --shared_libzip If you installed libzip in a custom location then configure like:
npm install --build-from-source --shared_libzip \ --shared_libzip_includes=/opt/local/include \ --shared_libzip_libpath=/opt/local/lib If you installed libzip with homebrew do:
npm install --build-from-source --shared_libzip \ --shared_libzip_includes=`brew --prefix`/include \ --shared_libzip_libpath=`brew --prefix`/lib BSD, see LICENSE.txt
