Node.JS - express - connect-redis how to delete a record

I have an example directly derived from an express document.

app.use(express.cookieParser());
app.use(express.session({ secret: "keyboard cat" }));
var RedisStore = require('connect-redis');
app.use(express.cookieParser());
app.use(express.session({ secret: "keyboard cat", store: new RedisStore }));

I know that this code will create a session id and automatically save the session id in redis databse. Correctly?

Now let's say the generated session_id was 555444, how can I delete a record when it is no longer needed?

Are any of these actions being performed?

store.destroy('555444', function(err) { ... })

or

app.get('/', function(req, res) {
    if (req.session.sid == '555444') {
        req.session.destroy(function(err) { ... });
    }
})

I faced a similar situation where I wanted to destroy an existing session and clear the cookie during the logout. This seems to work just fine for me (the store is an instance of RedisStore).

app.get('/logout', function (req, res) {
  res.contentType('json');
  store.destroy(req.sessionID, function () {
    req.session.destroy(function () {
      res.clearCookie(sessionOpts.key, { path: '/' });
      res.send({ success: true });
    });
  });
});

Github, backbone.js, node.js, express.js, mongodb, socket.io redisif you want to check it out. I have contributed to the reconfiguration of the backbone platforms.

Scroll it here on github

  • socket.io for real-time multi-user editing
  • mongodb data storage
  • redis for session management
  • redis pub / sub for record locks, so two users do not try to edit the same Todo

You just need to provide the sessionID to the destroy method, this will clear this session key from the Redis database. Here is the code that worked for me:

req.session.destroy(req.sessionID, function () {
    // Passport logout
    req.logout();
});
