I am new to the SharePoint world & I have been assigned to make a Single-page Application using any Framework (ReactJS/Angular) on SharePoint online (Microsoft 365).
The Application needs to take the whole screen, and integrate with SharePoint lists & Library.
I Have been doing some research lately, but I could not find anything straight forward that would get me going.
Edit: From my understand SPFX is used to create Web-parts that take a portion of a page. However for my case i am trying to create an App that takes over the whole page
