We CAN build the impossible! https://codepen.io/justinbmeyer/pen/yEGGoK

Referencing the superMap tag in the stache file, showing “Is Loading” while isPending is true, and then displaying the the stache for the component, once the data is loaded.

Justin Meyer

@justinbmeyer

it would use the todos returned by {}

Thomas Sieverding

@Bajix

For my use case, I want to explicitely disable data-url

Justin Meyer

@justinbmeyer

not for the first load though right?

Thomas Sieverding

@Bajix

As the data will be loaded after the fact

I’m delaying loading findAll until a websocket connection is established

Justin Meyer

@justinbmeyer

@RALifeCoach ok ... but that's different than what I'm talking about

Thomas Sieverding

@Bajix

Then I’m loading based off of time, and letting my websocket connection publish going forward

Christopher Oliphant

@RALifeCoach

Sorry, there are several different conversations going on at once

Justin Meyer

@justinbmeyer

@Bajix what do you mean by "based off time"?

sounds like you need a data-websocket behavior.

Thomas Sieverding

@Bajix

I have a creation time on my data, and I would want to query things created before connecting, but after the crreation time of the last thing cached

Justin Meyer

@justinbmeyer

ah ... last thing cached in localstorage?

Thomas Sieverding

@Bajix

Yes

Justin Meyer

@justinbmeyer

this is a perfect opportunity for a behavior

Thomas Sieverding

@Bajix

Oh?

Justin Meyer

@justinbmeyer

like .. this is exactly the scenario can-connect was built to handle

Thomas Sieverding

@Bajix

I know ;p

Justin Meyer

@justinbmeyer

well built to be ABLE to handle

doesn't handle it

Thomas Sieverding

@Bajix

Though I don’t see why data-websocket would be a behavior

Justin Meyer

@justinbmeyer

you query the websocket once it's connected for the new things right?

Thomas Sieverding

@Bajix

Nope

Though I suppose I could do it that way

Justin Meyer

@justinbmeyer

when / how do you query the new things?

Thomas Sieverding

@Bajix

I would query things using findAll after my websocket connection is online

Justin Meyer

@justinbmeyer

oh ... I would fire getList and forget

Thomas Sieverding

@Bajix

Then I’d use something like hydrateInstance to handling incoming data from my websocket connection

Justin Meyer

@justinbmeyer

ok, so I'm not sure how all this works ... but let me take a stab at some sudo code

Thomas Sieverding

@Bajix

Sure

onData: function( packet ) {
  var action = packet[0],
    data = packet[2];

  switch (action) {
    case 'DELETE channel':
      return Channel.model(data).destroyed();
    case 'DELETE message':
      return Message.model(data).destroyed();
    case 'DELETE user':
      return User.model(data).destroyed();
    case 'channel':
      return this.dispatch('channel', [Channel.model(data)]);
    case 'message':
      return this.dispatch('message', [Message.model(data)]);
    case 'user':
      return this.dispatch('user', [User.model(data)]);
  }
},

This is an example of a similar use-case to what I’m building now

      '{scope} onlineAt': function( scope, ev, onlineAt ) {
        var channel = scope.attr('channel');

        if (onlineAt) {
          Message.findAll({
            channel: channel._id,
            limit: channel.config.loadMessageCount
          });

          User.findAll({
            channel: channel._id,
            limit: config.chat.loadMessageCount
          });
        }
      },

So onlineAt would be the time my connection goes online

This was pre can-connect

My models were setup to emit newInstance on prototype.init on their constructor

I was combining the two data sets manually

back to steal-tools - I have in my package.son

  "system": {
    "main": "modules/page.players-redesign/player-bio/components/player-bio.js"
  },

/git/pgatour-cq-v2/front-end/node_modules/steal-tools/lib/graph/make_graph_with_bundles.js:83
    if( Array.isArray(cfg.main) ) {
                         ^

TypeError: Cannot read property 'main' of undefined
    at module.exports (/git/pgatour-cq-v2/front-end/node_modules/steal-tools/lib/graph/make_graph_with_bundles.js:83:23)

Leath Cooper

@IcculusC

not in system

it's a top level package.json field

Thomas Sieverding

@Bajix

@IcculusC It’s in both

Leath Cooper

@IcculusC

Thomas Sieverding

@Bajix

He should be doing this in system.main

the top level main is a fallback

Leath Cooper

@IcculusC

weird, in my experience it only works under the top level package.json object

Christopher Oliphant

@RALifeCoach

I removed it from the system object and I am getting the same result

This message was deleted

Leath Cooper

@IcculusC

well I learned something just now

Thomas Sieverding

@Bajix

@RALifeCoach Your paths are likely the issue

Christopher Oliphant

@RALifeCoach

how so?
