Customize front-end UI

Hi all,
I seen in documentation below :
https://www.theia-ide.org/doc/Composing_Applications.html
We can build our own IDE, is it possible to use a different web library to change the wall front end ?
Thanks for your help

Do you mean to use different library to phosphor for desktop like layouting?

Hi Anton, I mean actually maybe I’m wrong but you use React to generate the front end ? Is it possible to Rebuild the front end with another framework? Maybe I can keep the actual front end and create an extension that will communicate directly with the backend ? I don’t know if it’s clear…?

You can unbind all existing frontend widgets and create own widgets using another framework. Depending on what you are trying to achieve it can be quite a lot of work.
