session-data v1.1.2

session-data

The sessionData is a special area of the session used for storing data. Data are written to the sessionData and cleared after being used by the user. The sessionData is typically used in combination with redirects, ensuring that the data is available to the next page that is to be rendered.

Install

$ npm install session-data

Usage

Express 3.x

sessionData are stored in the session. First, setup sessions as usual by enabling cookieParser and session middleware. Then, use sessionData middleware provided by session-data.

var sessionData = require('session-data');
var app = express();

app.configure(function() {
  app.use(express.cookieParser('keyboard cat'));
  app.use(express.session({ cookie: { maxAge: 60000 }}));
  app.use(sessionData());
});

With the sessionData middleware in place, all requests will have a req.sessionData() function that can be used for sessionData.

app.get('/sessionData', function(req, res){
  // Set a flash message by passing the key, followed by the value, to req.sessionData().
  req.sessionData('info', 'Flash is back!')
  res.redirect('/');
});

app.get('/', function(req, res){
  // Get an array of sessionData by passing the key to req.sessionData()
  res.render('index', { sessionData: req.sessionData('info') });
});
