## What it is
connect-flash is a middleware for Connect and Express that provides flash messages stored in the session and cleared after display. It restores the flash functionality removed in Express 3.x and works with any middleware-compatible framework.

## Use cases
- show success or error messages after a redirect in Express
- display one-time notifications to users across page loads
- add flash message support to Express 3.x apps
- show form validation feedback after POST-redirect-get
- display login failure messages with Passport

## When to choose
- you use Express 3.x or Connect and need session-based flash messages
- you want messages that persist through a redirect and disappear after display

## When to avoid
- you use Express 4/5, where req.flash is often replaced by other session-based flash packages
- your app has no session middleware and you don't want to add it
- you need client-side or non-session notifications
