New Custom Handlers component for Chrome – make everything intensely
The HTML Standard section on Custom Handlers describes the procedure to register custom protocol handlers for URLs with specific schemes. When a URL is followed, the protocol dictates which part of the system handles it by consulting registries. In some cases, handlers may fall to the OS level and and launch a desktop application (eg. mailto:// may launch a native application) or, the browser may redirect the request to a different HTTP(S) URL (eg. mailto:// can go to gmail).

Protocol Handler Registration via Browser Extensions – make everything intensely
Custom URL schemes have traditionally served as an integration bridge between the browser and external capabilities. Schemes such as mailto: and tel: allow navigation to trigger actions beyond ordinary HTTP resource retrieval. The HTML Standard formalizes this mechanism through the Custom Scheme Handlers API, which enables websites to register themselves as handlers for specific URL schemes.

Understanding AT Protocol
I’ve been playing around with AT Protocol. The posts on this site are now published to standard.site, and I’ve written a (very basic) WordPress plugin to display posts from my PDS on the Now page of this site.
