Showing errors with Flash message (Node.js) | Doctor's appointment booking system - Part 5
In this video, I'm gonna show you the way to use Flash message with the Node.js platform. Flash messages are a great way to add some simple notifications to users of your website or application about important events that may have happened. As soon as the user navigates to another page, the flash message goes away.
Flash messages are semipermanent data used to display information to users of an application. These messages originate in your application server and travel to your users’ browsers as part of a session. Sessions contain data about the most recent interaction between a user and the application, such as the currently logged-in user, length of time before a page times out, or messages intended to be displayed once.
You have many ways to incorporate flash messages into your application. In this video, you use the connect-flash middleware module.
