The very first public release of the high-level Python web framework JustPy has been published to GitHub. JustPy is object-oriented, component-based, and does not distinguish between front-end and back-end programming.
As the framework’s developer Eliezer Mintz describes, “All programming is done on the back-end allowing a simpler, more productive, and more Pythonic web development experience.” He further hopes that “JustPy will enable teaching web development in introductory Python courses by reducing the complexity of web development.”
So, let’s see how to use JustPy and how it integrates with other Python tools.
First steps with JustPy
JustPy requires Python 3.6 or higher, and it is recommended to run the tutorial programs in a virtual environment so as not to affect the system-wide Python interpreter.
The documentation shows how to install JustPy and its dependencies, after creating a directory and creating and activating the virtual environment jp:
$ mkdir jptutorial $ cd jptutorial $ python3 -m venv jp $ source jp/bin/activate (jp) $ pip install justpy
On Windows, use
jp\Scripts\activate instead of
source jp/bin/activate to active the virtual environment.
Then, in the jptutorial directory, you can create the file test.py (another file name may be chosen instead) that contains the following code:
import justpy as jp def hello_world(): wp = jp.WebPage() jp.Hello(a=wp) return wp jp.justpy(hello_world)
Now, run the program by entering the command
$ python3 test.py and go to http://127.0.0.1:8000 or http://localhost:8000/ in your browser – and you should see “Hello!”. When you click on it multiple times, the number of clicks should be displayed.
Support for Matplotlib, pandas and more
