Nodejs Gzip write after end error zlib

Source:

nce a writable stream is closed, it cannot accept anymore data (see the documentation): this is why on the first execution your code will work, and on the second you’ll have thewrite after enderror.

Just create a new gunzip stream for each request:

http.get(url, function(req) {
   var gunzip = zlib.createGzip();
   req.pipe(gunzip);

   gunzip.on('data', function (data) {
     decoder.decode(data);
   });

   gunzip.on('end', function() {
     decoder.result();
   });

});
