PythonReact

Did you ever think: "We need a JS library turned into a python module used for console output in stead of rendering a webpage."? No? Well I did. So here it is.

Installation

This package is on pypi.
Installing can be done via pip

Windows:

pip install pythonreact

Mac/ Linux:

pip3 install pythonreact

Usage

If you are familliar with the JS library react this should be very easy.

Component

Everything is a component.
To create a new component, make a class that inherits from PythonReact.Component

import PythonReact


class MyComponent(PythonReact.Component):
    pass

Hello python react

To show something in the console we will add a render function. This render function should return a list of printable items or other Components.

import PythonReact


class MyComponent(PythonReact.Component):
    def render(self) -> list:
        return [
            "Hello",
            "Python React"
        ]

Let's make an object of that type:

# snip
my_comp = MyComponent()

It will automatically start printing now. And it will render your function.

State

If you have used React you know about state.

To create a state add it to the __init__ of your component. And then simply call the variables in your render function.

import PythonReact


class MyComponent(PythonReact.Component):
    def __init__(self):
        self.state = {
            "name": "Donkere",
        }

        super().__init__()

    def render(self) -> list:
        return [
            f"Hello {self.state['name']}!",
        ]


my_comp = MyComponent()

>>>
Hello Donkere!

Set state

Just as in React there is a set state function.

import PythonReact


class MyComponent(PythonReact.Component):
    def __init__(self):
        self.state = {
            "name": "Donkere",
        }

        super().__init__()

    def render(self) -> list:
        return [
            f"Hello {self.state['name']}!",
        ]


my_comp = MyComponent()
my_comp.set_state({"name": "New Name"})

>>>
Hello Donkere!
# Screen get's cleared
Hello New Name!
