Temporary Routes Using Meteor & Iron: Router?

Question

Is it possible to make a temporary route in Meteor using Iron: Router?

How it'll be applied: When a user asks a question they will be redirected into a chatroom with a custom parameter that I supply. When the user is done in the chatroom and leaves, I want this route to be destroyed.

ex: /chat/[custom parameter I set]

Answer 1

Use : in your route to represent a value which can change but is mandatory (i.e. /chatroom/12345 would work but /chatroom would not)

Router.route('/chatroom/:chatId', {
    name: 'chatroom',
    template: 'chatroom',
    layoutTemplate:"myLayout",
    data: function () {
        return ChatRoomData.findOne({_id:this.params.chatId});
    }
});

Or, you can make the parameter passed in optional by adding a ? too

Router.route('/chatroom/:chatId?', {
    name: 'chatroom',
    template: 'chatroom',
    layoutTemplate:"myLayout",
    onBeforeAction: function () {
        if (!!this.params.chatId)
           //Do Something with the chatId
           this.render('specificChatRoom', {
              data: function () {
                  return ChatRoomData.findOne({_id:this.params.chatId});
              }
           });
        else
           //Do Something else
           this.render('mainChatRoom');

        this.next();
    }
});
