Lecture 341:- Adding Flash Messages to more Actiions

To add flash messages to more actions, you will need to follow these steps:

1. Install the connect-flash package using npm:

arduinoCopy code

npm install connect-flash

1. Require the package in your app.js file:

javascriptCopy code

const flash = require('connect-flash');

1. Add the flash middleware to your app:

javascriptCopy code

app.use(flash());

1. Create a flash message in your controller, just like before:

javascriptCopy code

req.flash('success', 'Post deleted successfully');

1. In the controller action where you want to display the message, retrieve the message from the flash and pass it to the view:

javascriptCopy code

const flashMessages = res.locals.messages(); res.render('index', { flashMessages });

1. In your view, add code to display the flash message:

ejsCopy code

<% if (flashMessages.success) { %>  <div class="alert alert-success" role="alert">    <%= flashMessages.success %>  </div> <% } %>

1. Repeat steps 4-6 for any other actions where you want to display flash messages.
2. You can also use the error message type for displaying error messages:

javascriptCopy code

req.flash('error', 'There was an error deleting the post');

And in your view:

ejsCopy code

<% if (flashMessages.error) { %>  <div class="alert alert-danger" role="alert">    <%= flashMessages.error %>  </div> <% } %>

By adding flash messages to more actions, you can provide better feedback to the user and improve the overall user experience.
