hapi-flash

Reply interface decorated flash messages - for the [post,put,patch,delete] redirect to [get] pattern. Currently supports any session-based hapi authentication scheme that populates request.auth.credentials (such as hapi-auth-cookie).

Usage

Set Flash Message

Anywhere that you would would ordinarily issue a reply.redirect(url), use reply.flash(message, url).

The message parameter can be a single message object, or an array of message objects.

reply.flash(message) can also be called multiple times adding multiple flash messages if the redirect url argument is omitted, followed by either reply.flash(message, url), or the standard reply.redirect(url).

Retrieve Flash Messages

From any handler, or anywhere in the request pipeline where the reply interface is available, call reply.flash() with no arguments, and all flash messages will be returned as well as cleared from the flash cache. Flash messages are returned as an array.
