Bindings to libzip for handling zipfile archives in node.
varzipfile=require('zipfile');// Creating a zipfile objectvarzf=newzipfile.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 objectzf.readFile('world_merc.prj',function(err,buffer){if(err)throwerr;console.log(buffer.toString());});To handle large zipfiles and avoid the overhead of passing data from C++ to JS use the copyFile interface:
varzipfile=require('zipfile');varzf=newzipfile.ZipFile('./test/data/world_merc.zip');varzip_entry_name='world_merc.shp';varoutput_file='out/world_merc.shp';zf.copyFile(zip_entry_name,output_file,function(err){if(err)throwerr;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
