GZIP compression

The first simple thing you can do to reduce the bandwidth is to use GZIP compression, so everything that is sent over the wire gets smaller. Web servers such as Apache or nginx provide native support to compress responses on the fly, and it's better to avoid implementing your ad hoc compression at the Python level.

For example, this nginx configuration will enable GZIP compression for any response produced by the Flask app on port 5000, with an application/json content type:

    http {         gzip  on;         gzip_types application/json;         gzip_proxied      any;         gzip_vary on;          server {             listen       80;             server_name  localhost;                         location / {                  proxy_pass http://localhost:5000;             }         } 

From the client-side, making an HTTP request to the nginx server ...
