Let's say you create a zip file in-memory following the example from node-zip
's documentation:
var zip = new require('node-zip')()
zip.file('test.file', 'hello there')
var data = zip.generate({type:'string'})
How do you then send data
to a browser such that it will accept it as a download?
I tried this, but the download hangs at 150/150 bytes AND makes Chrome start eating 100% CPU:
res.setHeader('Content-type: application/zip')
res.setHeader('Content-disposition', 'attachment; filename=Zippy.zip');
res.send(data)
So what's the proper way to send zip data to a browser?
Using the archiver and string-stream packages:
var archiver = require('archiver')
var fs = require('fs')
var StringStream = require('string-stream')
http.createServer(function(request, response) {
var dl = archiver('zip')
dl.pipe(response)
dl.append(new fs.createReadStream('/path/to/some/file.txt'), {name:'YoDog/SubFolder/static.txt'})
dl.append(new StringStream("Ooh dynamic stuff!"), {name:'YoDog/dynamic.txt'})
dl.finalize(function (err) {
if (err) res.send(500)
})
}).listen(3000)
