express-zip allows you to do res.zip(files) in express, without creating any intermediary files on disk, and in 100% pure node.
var app = require('express')();
var zip = require('express-zip');
app.get('/', function(req, res) {
res.zip([
{ path: '/path/to/file1.name', name: '/path/in/zip/file1.name' }
{ path: '/path/to/file2.name', name: 'file2.name' }
]);
});
app.listen(3000);$ npm install express-zip
/**
* Respond with a ZIP attachment containting `files`, with an optional
* "save as" `filename` (default is attachment.zip), and then call `cb`
* when finished.
*
* @param {Array} files { name: <name>, path: <path> }
* @param {String|Function} filename that will be shown in "save as" dialog
* @param {Function} cb(err, bytesZipped) optional
*/
res.zip = function(files, filename, cb) {Borrows heavily from nulltask's express-csv, uses ctalkington's zip-stream for the actual zipping.
