koa-connect-flash
The flash is a special area of the session used for storing messages. Messages are written to the flash and cleared after being displayed to the user. The flash is typically used in combination with redirects, ensuring that the message is available to the next page that is to be rendered.
This middleware was extracted from Express 2.x, after Express 3.x removed direct support for the flash. koa-connect-flash brings this functionality to koa.
Install
$ npm install koa-connect-flash
Usage
Koa
Flash messages are stored in the session. First, setup sessions using koa-generic-session
middleware. Then, use flash
middleware
provided by koa-connect-flash.
var koa = ;var router = ;var session = ;var flash = ; var app = ; appkeys = 'keys';app; app; app;
With the flash
middleware in place, all requests will have a this.flash()
function
that can be used for flash messages.
app; app;
