Express and connect appeared to have removed their gzip functions because they were too inefficient. Are there any reliable solutions to gzip with express-js currently?
I have also searched npm and found for example:
https://github.com/tomgallacher/gzippo
gzippo pronounced g-zippo is a gzip middleware for Connect using Compress for better performance.
Gzippo has recently been developed(2 days ago) which I think is a good thing. I can't tell you about production usage. You should test/benchmark it yourself. I would also probably use a CDN for a live site or Nginx to host my static files instead of some nodejs module.
