How to export static /pages/page.js to be served as /page.html (not /page)

[osnwt]

I am trying to export static site to a set of *.html files. They can later be served by any HTTP server. The problem is that from a client view everything works, and requests to /somepage result in fetching /somepage.html. But if I refresh such page to get it from server directly, I have 404 error unless I add the html extension like /somepage.html.

In same cases it is possible to instruct a server to try known extensions like html or htm for requests without extension (MultiViews for Apache). Sometimes it is not possible. Is there any recommended way to refer to pages with full names (with .html extensions) when exporting a static site?

PS. Sufficient option could be to generate files without extension, that is, not page.html, but just page. How?

This configuration would depend 100% on how you are hosting it. What are you using to serve these files?

I am newbie with web apps. So I try different options to know how.

Particularly, I have a PHP Symfony-based backend with some API, and I tried to copy nextjs-generated static frontend files to Symfony's public directory to be served from there. Symfony does not map requests to /page into /page.html and returns 404. So I have to rename generated page.html to just page. Then it works.

Of course, I would hardly use such a mix of technologies. But as I said, I want to know more inner details. So perhaps I can tell next (maybe using custom webpack config) to not use html extension for generated static page files.
