Snap.Utils

Snap.Utils provides helper modules for making web apps with Snap Framework. The underlying design goal is to rely on more traditional HTTP-based methods of stateless control flow instead of relying on cookies and server state continuations.

Documentation

module Snap.Utils.Alert

Alerts uses GET request URI query parameters to display an alert on the next response page.

module Snap.Utils.Environment

Environment splices the -e runtime environment (ex: devel, prod, etc.) name into a template tag. This allows for splicing certain content only when in a specific runtime environment.

module Snap.Utils.ErrorLogger

ErrorLogger catches exceptions that are thrown all the way to the top of the site and handles them cleanly without crashing the application server.

module Snap.Utils.TargetPage

TargetPage captures the desired target page when interim pages need to be visited first before continuing onto the target page afterwards.
