What is the best format to deliver pages using Express?

Normally I use .js as page extension to work in Express, but I normally would work in Next.j…

For this particular project I DON’T want to work in REACT or Next.js… so I went ahead to use EJS… However, EJS requires “type”:“module” in json files, which changes the format of the import files I am using…

If I work on HTML then Express .render doesn’t work, and I would need to change the code to something else…

Seems like coding is never uniform…

What do you think is the best and/ or more common format when using Express.js?
