Controlling Session Start with LocomotiveJS

Question

I know it is possible to control session start with express and connect middleware. Like suggested here: Controlling Session Start with express and connect middleware

Is it possible to control session start with LocomotiveJS?

I don't want to start session for every user - I just want to start it when user successfully logs in.

I'm already storing session in MongoDb (myabe in the future I will use Redis) and creating not required session for every user which enter the page seems to be a waste of resources.

I just found the solution: Maybe LcomotiveJS itself does not support it directly, but it can be easily implemented using Express (and Locomotive is on top of it).

Instead of declaring session as:

this.use(express.cookieParser());
this.use(express.session({
    secret: '123qwemax',
    cookie: {maxAge: 60 * 60 * 1000},
    store: new MongoStore({
      url: 'mongodb://localhost:27017/tests'       
    }),
}));

Declare your session as:

this.get(/^\/login\/.*/, express.cookieParser());
this.get(/^\/login\/.*/, express.session({
    secret: '123qwemax',
    cookie: {maxAge: 60 * 60 * 1000},
    store: new MongoStore({
      url: 'mongodb://localhost:27017/tests'       
    }),
}));

This way session will start any time we will go to /login/.* pages.

I don't know why this.all was not working...

Of course examples doesn't cover logic for starting session for logged users only. It just shows that handler functions for session can be added to defined urls - not to every (like with this.use). — irla, Sep 12 '13 at 19:31
