I know a typical practice to build an Electron app is to follow SPA (Single Page App). I still would like to split my html content into separate files for easy maintenance. There is still the main index.html file which is to be loaded on startup.
My question is: is there a protocol for inserting a part of html content from a different files? For eg. in Django, there is a include and extend tags where you can insert an entire html file into the body of another parent html file or retain certain features from another html file.
