How to Display Flash Messages using connect-flash Module in Node.js and Express

To display flash messages using the connect-flash module in Node.js and Express, you will need to perform the following steps:

Install the connect-flash module by running npm install connect-flash in your terminal.

2. In your Express app, require the connect-flash module and add it as middleware. For example:

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

app.use(flash());

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

app.use(flash());

In your route handlers, set flash messages using the req.flash function. For example:

req.flash('success', 'Welcome to our website!');

1	req.flash('success', 'Welcome to our website!');

In your views, display the flash messages using the req.flash function. For example, in an EJS template:

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

<% if (success) { %>

<%= success %>

</div>

<% } %>

Make sure to call req.flash() after each redirect, otherwise the message will be lost.

6) You can also add different type of flash message like error, success, warning and info.
