How to enable nginx enable gzip

In this short tutorial we are going to learn how to enable gzip compression

Open the nginx configuration file /etc/nginx/nginx.conf with sudo:

sudo nano /etc/nginx/nginx.cong

Inside the http section append the following lines:

    gzip  on;
    gzip_disable "msie6";
    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

In our gzip_types section we included css, json, xml and javascript to use gzip compression. The gzip_disable uses a regex on the user agent, we added this line since nginx could crash with msie6, check here the official doc on gzip_disable.

finally restart the server:

sudo service nginx restart

More options that you can add to the configuration:

    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_buffers 16 8k;
    gzip_http_version 1.1;

You can se more options on the compression of the responses, check here all the options available.
