Seeking assistance with setting up connect-flash for my nodejs express app. My goal is to display a flashed message when users visit specific pages. Utilizing ES6 package module type in this project, my code snippet is as follows. No errors are logged in the console, yet no flashed message appears on visiting the /privacy-policy route.
// Package Imports
import express from 'express';
import path from 'path';
import ejsMate from 'ejs-mate';
import session from 'express-session';
import flash from 'connect-flash';
import methodOverride from 'method-override';
import { fileURLToPath } from 'url';
import mainRoute from './routes/main.js';
import contactRoutes from './routes/contact.js';
// Path Setup
const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
// App Initialization
const app = express();
app.engine('ejs', ejsMate)
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'))
app.use(express.urlencoded({ extended: true }));
app.use(methodOverride('_method'));
app.use(express.static(path.join(__dirname, 'public')))
// Session Configuration
const sessionConfig = {
secret: 'thisshouldbeabettersecret!',
resave: false,
saveUninitialized: true,
cookie: {
httpOnly: true,
expires: Date.now() + 1000 * 60 * 60 * 24 * 7,
maxAge: 1000 * 60 * 60 * 24 * 7
}
}
app.use(session(sessionConfig))
app.use(flash());
// Routes
app.use('/', mainRoute);
app.use('/contact', contactRoutes)
app.get('/privacy-policy', (req, res) => {
req.flash('test message', 'success')
res.render('privacy')
});
app.get('/terms-of-service', (req, res) => {
res.render('terms')
});
app.all('*', (req, res, next) => {
next(new ExpressError('Page Not Found', 404))
})
app.use((err, req, res, next) => {
const { statusCode = 500 } = err;
if (!err.message) err.message = 'Oh No, Something Went Wrong!'
res.status(statusCode).render('error', { err })
})
app.listen(3000, () => {
console.log('Serving on port 3000')
})
Questioning the approach to importing connect-flash with ES6 syntax. What steps can be taken to enable connect-flash functionality? Given the limitation on using import rather than require syntax due to other modules utilized in the application, how else could dynamic messages be displayed upon user redirection?
Your guidance is highly appreciated.
