Overview

Sappy is a simple, single-page application (SPA) web server for end-to-end testing.

The Python standard library includes a web server that works great for serving up files:

$ python3 -m http.server 8080
Serving HTTP on 0.0.0.0 port 8080 ...

$ curl http://localhost:8080/index.html
<!DOCTYPE html>
<html>
  <head>
    <title>Example Index</title>
...

But when used to serve up single-page applications, a 404 is returned whenever any page other than the index is accessed directly:

$ curl http://localhost:8080/login
<!DOCTYPE html>
<html lang=en>
  <title>Error 404 (Not Found)</title
...

This project builds on the existing web server code to forward all requests to the index. The single-page application’s client-side routing can then display the page that corresponds to that request’s URL.
