Build a web server framework using Python. Litefs was developed to implement a server framework that can quickly, securely, and flexibly build Web projects. Litefs is a high-performance HTTP server. Litefs has the characteristics of high stability, rich functions, and low system consumption.

It can be installed via pip:

$ pip install litefs

It can be installed via source code:

$ git clone https://github.com/leafcoder/litefs.git litefs

$ cd litefs

$ python setup.py install

Firstly, let's write a basci example via litefs. Save it to "example.py".

# /usr/bin/env python

import litefs

litefs.test_server()

Secondly, you should create a directory named "site" (or any other name which is same as __"--webroot"__).

$ mkdir ./site

Thirdly, you can copy the below code into a new file "./site/helloworld.py".

def handler(self):

return "Hello World!"

Run "example.py", visit "http://localhost:9090/helloworld" via your browser. You can see "Hello World!" in your browser.

$ ./example.py
