How to enable Brotli compression in nginx on ubuntu

This is useful if (for example) Google Lighthouse gives you this message:

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.

Brotli reduces file sizes more than the other compression algorithms.

sudo apt-add-repository -y ppa:hda-me/nginx-stable
sudo apt-get update
sudo apt-get install brotli nginx nginx-module-brotli

(the step above it different if you don't have apt-get... there's a yum equivalent, and a 'download and unzip' equivalent too.

Edit your nginx.conf file --


sudo nano /etc/nginx/nginx.conf

Load the module when nginx restarts, by adding these lines:

load_module modules/;
load_module modules/;

Now locate the nginx config file specific to your site. e.g. it should be in /etc/nginx/sites-available/

 # gzip
gzip on;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_types text/plain text/css text/xml application/json application/javascript application/xml+rss application/atom+xml image/svg+xml;

# brotli
brotli on;
brotli_comp_level 6;
brotli_types text/xml image/svg+xml application/x-font-ttf image/ application/x-font-opentype application/json font/eot application/ application/javascript font/otf application/xml application/xhtml+xml text/javascript  application/x-javascript text/plain application/x-font-truetype application/xml+rss image/x-icon font/opentype text/css image/x-win-bitmap;
Nginx web server needs a restart for the static contents to be compressed.

sudo systemctl restart nginx
