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
