express-flashyo

Flash messaging for Express 4.x

Install

npm install flashyo --save

Initialise

app.use(require('express-session')); // OPTIONAL 
app.use(require('express-flashyo'));

Use

Response

Using res.flash(message, [level]) or res.flash({ message: '...', customKeys: 123 }) sets values straight away onto the res.locals object (shown in example) so your view engine can render the data.

app.use(require('express-flashyo'))
app.get('/', function(req, res) {
 
  res.flash('Welcome to this crazy Express app!');
  // res.locals.flashyo = [ 
  //   { message: 'Welcome to this crazy Express app!' } 
  // ]; 
 
  res.flash('Welcome to this crazy Express app!');
  // res.locals.flashyo = [ 
  //   { message: 'Welcome to this crazy Express app!' } 
  // ]; 
 
  res.render('layout');
 
});

Delayed Response

By using a delayed response requires express-session to be initialised beforehand. When req.flash(message, [level]) or req.flash({ message: '...', customKeys: 123 }); the message is places in the session so that the next request has the flash message places in res.locals.

// app.use express-session 
// app.use(require('express-flashyo')); 
 
app.get('/setup', function() {
  setTimeout(function() {
    req.flash('You\'re site is now setup');
    res.redirect('/');
  }, 600);
});
 
app.get('/', function(req, res) {
  console.log()
})
