使用
var StreamZip = require('node-stream-zip');
var zip = new StreamZip({
file: 'archive.zip',
storeEntries: true
});
zip.on('error', function(err) { /*handle*/ });
zip.on('ready', function() {
console.log('Entries read: ' + zip.entriesCount);
// stream to stdout
zip.stream('node/benchmark/net/tcp-raw-c2s.js', function(err, stm) {
stm.pipe(process.stdout);
});
// extract file
zip.extract('node/benchmark/net/tcp-raw-c2s.js', './temp/', function(err) {
console.log('Entry extracted');
});
// extract folder
zip.extract('node/benchmark/', './temp/', function(err, count) {
console.log('Extracted ' + count + ' entries');
});
// extract all
zip.extract(null, './temp/', function(err, count) {
console.log('Extracted ' + count + ' entries');
});
// read file as buffer in sync way
var data = zip.entryDataSync('README.md');
});
zip.on('extract', function(entry, file) {
console.log('Extracted ' + entry.name + ' to ' + file);
});
zip.on('entry', function(entry) {
// called on load, when entry description has been read
// you can already stream this entry, without waiting until all entry descriptions are read (suitable for very large archives)
console.log('Read entry ', entry.name);
});
