That's nice! So decompression is happening on the client, but not at the JS level, instead you are taking advantage of browser's ability to accept zip-encoded

That's nice! So decompression is happening on the client, but not at the JS level, instead you are taking advantage of browser's ability to accept zip-encoded content from the server, hence decompression is done the by browser's own behavior when it receives a "content-encoding: gzip" stream or something like that.
