Grav uses its filesystem as a database, and heavily relies on caching (filesystem, memcache, redis…)
There's an admin plugin with a nice user-interface which allows to:
- add/edit pages and articles
- configure the whole system and the plugins
- run updates and backups
- clear the cache manually
Grav is not a static site generator, as it handles dynamic operations via plugins using an eventing system. Yet it is not a Wordpress-like CMS that renders all templates on every request, as it caches rendered templates (among others).
As a concept, Grav brings the best of both worlds. But the current implementation is far from scalable (Grav team recommends setups with at max a few thousand pages).
- Fast setup, amazing documentation
- Nice responsive design
- Many useful plugins
- Multi-language support (url-based differenciation, support for language-based slugs)
- Dates are not translated
- Not optimized for big websites (1000s of pages), as building collections/taxonomies (categories, tags, events) requires parsing through all of the pages (can be made faster with SSDs, but still requires lots of RAM)
You can find both the Grav core and a package with the Admin plugin in the downloads section of the Grav site. If you download the package, simply extract it, and point your web server there to be guided through setup.
Sample configuration files are available for nginx, caddy, Apache, IIS and lighttpd.
Updates can be made through the admin interface (from the main dashboard), or using the command-line tool, from your webroot : bin/gpm selfupgrade
Although backups are achievable through the web interface, data storage within Grav only relies on files, so making daily backups of your website can be as easy as a cron job running rdiff/rsync for the user/ folder in the webroot.
The default Antimatter theme supports basic microformats2 out-of-the-box. Support for h-feed name and description is available in a fork of the Antimatter theme. The About Me plugin adds additional information, including h-card on the home page and links to your identity in silos and other sites.
Themes and plugins generally provide full instructions for adding either via the command line or through the Grav admin interface.
Open Graph / Twitter Cards
To automatically generate og: and twitter: tags for your pages (can be overriden on a per-page basis), there's the socialmeta plugin.
OleVik has written a plugin that will display RSS feeds in a Grav site. This can be useful for bringing in content from elsewhere.
