🔗 A Guide to Writing slog Handlers

The standard library's log/slog package has a two-part design. A "frontend," implemented by the Logger type, gathers stuctured log information like a message, level, and attributes, and passes them to a "backend," an implementation of the Handler interface. The package comes with two built-in handlers that usually should be adequate. But you may need to write your own handler, and that is not always straightforward. This guide is here to help.
