connect-flash-now

Modern fork of connect-flash with a safe Array.isArray fallback.

This package applies a small fix to remove the use of util.isArray(), which is deprecated in Node.js, while preserving the original flash messages behavior and adding compatibility with modern Node.js versions.

What Changed

• The lib/flash.js file was updated to use Array.isArray() with a readable and compatible fallback.
• The tests were migrated to a modern runner that works with current Node.js versions.
• The package was renamed to connect-flash-now to differentiate it from the original.

Installation

$ npm install connect-flash-now

Modern Usage (Express / Current Node.js Versions)

const express = require('express');
const session = require('express-session');
const flash = require('connect-flash-now');

const app = express();

app.use(session({
  secret: 'keyboard cat',
  resave: false,
  saveUninitialized: false
}));
app.use(flash());

app.get('/flash', (req, res) => {
  req.flash('info', 'Flash is back!');
  res.redirect('/');
});

app.get('/', (req, res) => {
  const messages = req.flash('info');
  res.send(messages);
});

app.listen(3000, () => {
  console.log('Server running on http://localhost:3000');
});
