This is a Linux shell (bash) script that gzip-compresses the static assets contained within a production build of a Meteor webapp. It has been tested under CentOS 7. This script is intended to be used when Nginx is running as the web server and the 'gzip_static' configuration option is enabled. When the client supports gzip compression, Nginx wi…
