When you are serving a website, you have to serve dynamic content, but you also need to serve static files, such as CSS, JavaScript files, and images. While uWSGI is capable of serving static files, it adds an unnecessary overhead to HTTP requests and therefore, it is encouraged to set up a web server, such as NGINX in front of it.

NGINX is a web server focused on high concurrency, performance, and low memory usage. NGINX also acts as a reverse proxy, receiving HTTP requests, and routing them to different backends. Generally, you will use a web server, such as NGINX in front, for serving static files efficiently and quickly, and you will forward dynamic requests to uWSGI workers. By using NGINX, you can also apply rules and benefit from its reverse proxy capabilities.

Install NGINX with the following command:

sudo apt-get install nginx

If you are using macOS X, you can install NGINX using the command brew install nginx. You can find NGINX binaries for Windows at https://nginx.org/en/download.html.
