A message flashing module. Inspired by Flask.
$ npm install node-twinkle
var express = require('express'),
flash = require('node-twinkle');
var app = express();
app.configure(function(function() {
app.use(express.cookieParser());
app.use(express.session({ secret: 'My Secret Key' });
app.use(flash); // make sure to put this before your routes dispatchers.
app.use(app.router);
});// in your view functions:
app.post('/signin', function(req, res) {
// actual logic for user signing in.
req.flash('You have successfully signed in.');
res.redirect('/');
});
// in your templates: (we use ejs as an example, however you can use any template as you like)
<body>
<% if (has_flashed_messages()) { %>
<% get_flashed_messages().forEach(function(message) { %>
<p><%= message %></p>
<% }) %>
<% } %>
</body>Examples are under the 'example' directory.
To test node-twinkle, make sure you have mocha installed, then run the following command:
