How ToUI works

How ToUI creates web applications

ToUI uses Flask to create web applications. To make the website responsive, ToUI communicates with JavaScript through WebSockets. The WebSocket communication is established using the Python package Flask-Sock and the JavaScript object WebSocket. JavaScript sends the document object to Python while Python sends ‘instructions’ back to JavaScript:

How ToUI creates desktop apps

ToUI uses pywebview to create graphical user interfaces (desktop apps). The communication between Python and JavaScript is similar to web apps but using js_api object in pywebview instead of WebSockets.

Security?

For web apps, ToUI uses Flask web framework, Flask-Sock for communicating through WebSockets, and Flask-BasicAuth for restricting access to the website. To know more about the security of these Python packages, please find their documentations below:

• Flask docs

• Flask-Sock docs

• Flask-BasicAuth docs

ToUI uses pywebview for making desktop apps. To learn more about its security, please check this link: pywebview docs. Note that pywebview can create two types of apps: serverless apps or apps built by running a local web server. However, ToUI currently creates only serverless pywebview apps.
