A simple Django app for doing webchat over HTTP, the frontend is implemented in React using Typescript, and uses the fetch API for long polling.
Make sure you've got a recent python (3.4+, 2.7 not supported by Django 2.0+) installed, with pip and virtualenv
Usually for developing, I do something like:
$ virtualenv venv
$ source venv/bin/activate
(venv) $ pip install -r requirements.txt
(venv) $ python manage.py runserver
For production usage you'll wanna look into using uwsgi, gunicorn or a similar WSGI-based application server.
Make sure you have a recent version of NodeJS installed, with npm and/or yarn.
For setting up the environment and installing the needed packages with yarn, feel free to substitue with npm:
$ cd webapp
$ yarn
For development there's a watch script, call it like:
$ yarn watch
For building a minified production bundle:
$ yarn start
The frontend uses a few polyfills for supporting IE10+, these include babel-polyfill for Promise and whatwg-fetch for fetch.
