Chalk'it

Welcome to Chalk'it. Chalk'it ambition is to allow technicians, scientists or engineers, not specialists in web technologies, to build their own web applications based on the Python code, JavaScript code or web-services they develop. Watch this 5 minutes video for a quick introduction: https://www.youtube.com/watch?v=vY8I1XwKs9k or this more detailed demo: https://www.youtube.com/watch?v=4O2IfRogeCc.

Currently, Chalk'it allows to export and share standalone HTML apps with Python and/or JavaScript code, thanks to Pyodide. Since version 0.5.0, Chalk'it is able to run standard Python code and host related dashboard as Docker images.

See the demos gallery and templates gallery for examples with code.

For more details, you can browse the online documentation.

Deploy

Rename your dashboard file to dashboard.xprjson and deploy it using Docker.

Use this Dockerfile:

FROM python:3.11

# assume your application is named application.xprjson
COPY dashboard.xprjson dashboard.xprjson

# install py-chalk-it and gunicorn
RUN pip install py-chalk-it gunicorn

# this configuration is needed for your app to work, do not change it
ENTRYPOINT ["gunicorn", "chlkt.render:app", "run", "--bind", "0.0.0.0:80"]

Build the docker image:

docker build . -t application

Run it:

docker run -p 5000:80 application

Your dashboard will be displayed on port 5000.

Roadmap

• 3 clicks dashboard cloud sharing
• Command line interface (project open, render ...)
• PyDeck support
