How to set Socket.IO handlers in SailsJS on client side in DOM?

Question

Node.js

After I decided to write a simple to-do list using sockets, I got into the off-docs, from the docks I realized that the binding action occurs according to the principle: a handler is placed in the controller that notifies of all changes in the Model, and it is called subscribe .

Further, on the client side in JS, you can use the functions of the basic suckat socket.io , as well as additional gingerbread of Sails itself, which are described on the same page of the docks, a little resting on the use of this functionality, I looked at stackoverflow - in which I was told to look at the cast on using sockets .

I caught the main point and was able to get my controller to follow the updates using the method specified in the cast

subscribe: function (req, res) {
    Task.find(function foundTask (err, tasks) {
      if (err) return next(err);

      // оповещает когда создается запись
      Task.subscribe(req.socket);
      // оповещает когда произошло обновление или удаление
      Task.subscribe(req.socket, tasks);
    });
  }

But I just can't understand how on the client side you can create a handler that could update the list?

I realized that it all comes down to the fact that when updating, you need to make sure that this update is transferred as a list to the DOM using even banal jquery, but I don’t know the approximate algorithm of actions used for such manipulations.

If you can, tell me the algorithm, article, docks, or code example for this task.

Answer 1

subscribe subscribes you to certain events. If I understand everything correctly, then in the controller methods that change the model, you need to select the publish methods, for example, publishCreate.
Then all subscribed clients will receive the message.
