Nginx how to make normal redirect from .html to address without extension?

Question

Nginx

I recently switched to Ngnix using this docs.rtcamp.com/easyengine/.
Everything pleases, wordpress is installed and works quickly.
However, there are problems with the usual static html site.
Its structure is as follows:
Directory
Directory
index.html
page1.html
page2.html
page3.html
If on Apache (previously configured redirects from www in .htaccess, and .html became generally wonderful), everything works correctly - when you go to site.ru/ page1 opens a page on the page1.html server and stuff like that,
then only the main site opens on Ngnix, site.ru(page index.html), at the addresses site.ru/page1 (or site.ru/page1/ - with a slash) the error "404 Not Found" pops up. Pages open only directly with extensions, for example site.ru/page1.html .
Question - how and how to set up redirects in the Ngnix web server in my case, so that everything works correctly?

Try it:

location / {
  # do nothing it the extension is already present
  if ($request_filename ~* ^.+.html$) {
    break;
  }
  # add .html if it was not present
  if (-e $request_filename.html) {
    rewrite ^/(.*)$ /$1.html permanent;
    break;
  }
}
