I'd like to know if it's possible to have {filename}.html generated for every {filename}.html.twig? I know one solution is to copy and paste the source code from the browser, but is there a more efficient way of doing this?
Thank you in advance.
Such solution, I think, will satisfy your needs.
curl www.yoururl.com > /path/to/yourfolder/file.html
Have a look below story, if you interested in.
Story
A few months ago, i was working on a yii2 project. The index page was loading in 3 seconds because of response from external services. Cloudflare and other caching scenarios weren't succeeded - I came up with 2.5 seconds best.
After 2-3 days of thinking period, I found a nasty solution :)
Created a cache-less, fresh version of homepage and wrote a crone job, to fetch the contents of that page and write into index.html file inside public (in yii2 web) folder in every 2 minutes.
Other pages were ok - (<0.2s), so didn't wrote anything for them.
All I've done, was
curl www.example.com > /path/to/web/index.html
