This is a cheat sheet for updating your hexo blogs, which assumes you have already set up the theme.
$ hexo new [layout] <title>
In my case I generally use post for layout, also since I’m using local environment I run commands with npx.
$ hexo clean && hexo g
This will clean the old generated files and regenerate the static files.
$ hexo s
This allows you to preview locally.
$ hexo d # or directly hexo clean && hexo g && hexo d
This will deploy the static files to the platform (should be configured in the _config.yml).
