How to clean all sessions in Node.js (heroku + redis)?

Question

I'm using node.js (Expressjs) hosted on heroku.

Sessions are stored in redis (Redistogo plugin for heroku):

RedisStore = require('connect-redis')(express)
app.use express.session
      secret: process.env.CLIENT_SECRET
      cookie: { maxAge: 604800000 }
      store: new RedisStore {client: redis}

After the user logged in I store his info in req.session:

after_user_logged_id = (req, user)->    
  req.session.current_user =
    id: user._id
    name: user.name

I need to restart the server and clean all sessions: logout all users to force them login one more time. How should I do this? Restarting the redis plugin doesn't help.

redis.flushdb() may be a bit extreme if you end up storing something else in redis. You just need to delete all the "sess:*" keys. Unfortunately, there is no del *, so you can use something like this:

redis.keys("sess:*", function(err, key) {
  redis.del(key, function(err) {
  });
});
