I would like to know if it is possible to implement an SP application WITHOUT using yeoman.
Let me explain: I would like to create an application using VueJS and WebPack (maybe without gulp and Typescript), change the Typescript version used, customizing files as I like.
I have seen that it is possible to integrate VueJs into a solution, and I have also seen that it is possible to add configurations to WebPack, but I am a type that likes to understand what is underneath and have the TOTAL control on the application, I do not like very much the tools that do everything.
Does anyone know if it is possible to create an SPFX application from scratch? Is there a tutorial?
