Whether the Editor Extension implementation of Theia is similar to eclipse RCP? Configure the editor’s editable suffix and specific implementation class through extension. There are init(), createpartcontrol(), dosave(), setinput(), onface(), and dispose(). Whether it is in the same form as creating editor in RCP. Do you have Theia help?
