mondora / asteroid Goto Github PK

Would appreciate a code example. Don't get it setup...

(Sorry if i don't mark this as a question, i'm new here)
By the way, i find that Asteroid is amazing! Good job!
So, i am currently developing a Ionic Framework App (Android), to communicate with a Meteor App (with it's own server), and i managed to succeed when testing in the browser (Google Chrome), but when i installed the app on a real Android device, it gave me an error...

WebSocket connection to 'ws://my.meteor.app.server' failed: Error during WebSocket handshake: Status line does not end with CRLF

It shows me that the error is on ddp.js, line 62. I have tried some things, like adding '\r' to the end of some variables, but i don't quite understand this WebSocket thing... Is there anyway someone can help me?

Hi!

I've created a Chrome Extension, basically a background page that listens to a browser action (pressing on the extension icon). When that happens it send information about the page to the Meteor Backend.

The problem relies in the fact that everytime I open Chrome the background page logs in with twitter and opens a new tab in the browser.

Is there a way to do the login process in the backround? Or maybe store the credentials?

Am I explaining myself properly?

Thanks!

Refactor Calls : Can we write the code for calls/loginWith etc to be similar to meteor .. which takes a callback .. rather than returning the promise. Its same .. but keeping api similar makes life simpler

I want to fetch data from collection with sort
var prod=Production.reactiveQuery({sort: {index : -1},productionId:$cookies.productionid});
sort is not working here

To fix, look here:
https://github.com/mondora/asteroid/blob/master/src/core/asteroid-methods.js#L135

The updated promise of a call or apply call must always be resolved. It would probably be useful to resolve it with info on the success or failure of the call.

Hi @pscanf you know that classic pattern for implementing search, where you resubscribe to the same publication with a different query on keyup?

I've got this implemented with Asteroid and it's not working.

It seems like anytime I pass arguments into subscribe, nothing ever comes out, even though my publication is fine (verified from Meteor's own client).

Have you tried using subscribe with a query and had it working?

Asteroid files, unminified, amount to ~98k right now (32KB for asteroid.browser.js, 58KB for q.js, and 8.5KB for ddp.js). It would help with page load speed to have them concatenated and minified on CDNjs and jsDelivr.

    Ceres.subscribe("product-latest-10");
    var Products = Ceres.createCollection("products");

and

Products.find({});

However the Products here is undefined. I couldn't find what exactly the problem. Subscription is fine and return all messages correctly. Seems likes the TODO's asteroid code is different than the current code on github as I have to change the initialization to:

Ceres = new Asteroid('localhost:3000', false, true);

There seems to be no LICENSE file inside the Asteroid codebase.

As I understood from Paolo Scanferla during the 2014-11-07 Meteor Italia meeting, the code is released under the MIT license.

I will be happy to submit a Pull Request if this may help, please just let me know.

Has anyone built a login UI that uses Asteroid under the hood to login with user/pass, Facebook, Google, Twitter and GitHub?

Seems like an important part of the work is already done in @splendido's useraccounts, or @Differential's accounts-entry.

Hi !
The whole stuff is a really nice package and a great work. I'm already enjoying it using it.
What do you think about implementing 'observe' -> http://docs.meteor.com/#observe

The meteor-ddp package support it : https://github.com/eddflrs/meteor-ddp.

The implementation looks pretty straightforward :

https://github.com/eddflrs/meteor-ddp/blob/master/meteor-ddp.js#L153
and
https://github.com/eddflrs/meteor-ddp/blob/master/meteor-ddp.js#L212

So what do you think about it ?

Hi @pscanf,

I was looking at the Meteorpedia list of DDP clients implemented in JavaScript and saw Asteroid along with @eddflrs's meteor-ddp. Since meteor-ddp already existed when you started this project, I was wondering what the reasons were for creating a new implementation, and how Asteroid compares with Meteor-DDP.

Thanks,
Dan

So you don't have to learn/do stuff differently.

They should be transparent, although what the functions return might be wrapped with more compatibility stuff.

Is this possible - if not (when) will it be?

Can't see any mentions of this in the source code or documentations...

I'm trying to do server-side rendering (in node.js), using Asteroid as the data layer.

Is there anyway to do an async data fetch and run a callback when there's data available?

Late Edit: I've already tried the ready promise on subscriptions, but it never seems to get executed. I can't even get a simple script to log results and exit.

For some reason I can't make Facebook or Twitter Login to work on my chrome extension

        this.ddp = new Asteroid("localhost:3000");


        this.ddp.on('connected', =>
            console.log 'Connected'


            this.ddp.resumeLoginPromise.then( ->
                console.log ('ok')
            ).fail( =>
                console.log 'fail, now log in'

                this.ddp.subscribe("meteor.loginServiceConfiguration").ready.then =>
                    #this.ddp.loginWithTwitter()
                    this.ddp.loginWithFacebook()
            )
        )

This sends me to an endlessly loading new tab.

The following images are the callback urls for the facebook and twitter apps.

Any idea on why is this happening?

Thanks.

Here is the piece of code that got me a bit trouble implementing Facebook / Google oauth login with Asteroid. The problem is that not all service use the same structure in the database as of the latest meteor. service.clientId should be change to some if else.

Asteroid.prototype._getOauthClientId = function (serviceName) {
    var loginConfigCollectionName = "meteor_accounts_loginServiceConfiguration";
    var loginConfigCollection = this.collections[loginConfigCollectionName];
    var service = loginConfigCollection.reactiveQuery({service: serviceName}).result[0];
    return service.clientId;
};

Here is the structure:

{
        "service" : "facebook",
        "appId" : "xxx",
        "secret" : "xxx",
        "_id" : "xxx"
}
{
        "service" : "twitter",
        "consumerKey" : "xxx",
        "secret" : "xxx",
        "_id" : "xxx"
}
{
        "service" : "google",
        "clientId" : "xxx",
        "secret" : ""xxx,
        "_id" : "xxx"
}

// Connect to a Meteor backend
var ceres = new Asteroid("localhost:3000");

// Use real-time collections
ceres.subscribe("tasksPublication");
var tasks = ceres.getCollection("tasks");

tasks already contains values in tasks._set._items internal object

tasks.insert({
  description: "Do the laundry"
});
// Get the task
var laundryTaskRQ = tasks.reactiveQuery({description: "Do the laundry"});
// Log the array of results
console.log(laundryTaskRQ.result);

laundryTaskRQ.result in this (pseudo-synchronous) case is always empty array

// Listen for changes
laundryTaskRQ.on("change", function () {
  console.log(laundryTaskRQ.result);

In this case, result contain actual values.

});

My questions:

1. Does reactiveQuery have synchronous behavior in this example? Or your example incorrect?
2. if (1) is true, does Collection have API methods to get actual values in already existed ._set._items ?

Using Chrome.

var ddp = new Asteroid("localhost:3000");

ddp.on('connected', function() {
  console.log("connceted");
  ddp.loginWithGoogle();
});

I get this error:

Uncaught TypeError: Cannot read property 'reactiveQuery' of undefined

From this method:

Asteroid.prototype._getOauthClientId = function (serviceName) {
    var loginConfigCollectionName = "meteor_accounts_loginServiceConfiguration";
    var loginConfigCollection = this.collections[loginConfigCollectionName];
    var service = loginConfigCollection.reactiveQuery({service: serviceName}).result[0];
    return service.clientId || service.consumerKey || service.appId;
};

rollback functionality via asteroid

in mongo we can do like this
db.transactions.insert( {
_id: 1, source: "A", destination: "B", value: 100, state: "initial", lastModified: new Date()
})

how do i perform same in asteroid upon insert,update, or remove?

Implement having the server time as parameter of the connection.

Hi,

can we create tracker over the variables and define dependencies between them ..

like : http://docs.meteor.com/#/full/tracker_dependency

When i try login with facebook it gives me, "Uncaught TypeError: Cannot read property 'reactiveQuery' of undefined "

How do we handle the onReady/onError callback in a subscription ? Asteroid.subscribe(name,arg, { onReady: ...

callbacks Function or Object
Optional. May include onError and onReady callbacks. If a function is passed instead of an object, it is interpreted as an onReady callback.

http://docs.meteor.com/#/full/meteor_subscribe

Hi !

How one would handle persistent login with this nice asteroid lib ? I mean, if I want user to be able to close the browser and come back how could I do that without (i know its bad) saving the password and email locally. Woops my finger on fire.

Thanks a lot for any helpful advices

There must an overall example on how to use asteroid. With issues which might arise?
Any one?

Is there any way to get feedback on whether or not a subscription is still loading documents? I'm using this on a mobile application and would love to display a loading icon while records are still loading. Great work, by the way!

I'm getting this error from Meteor on the server side

W20141127-09:50:17.280(-8) (oauth_server.js:398) Error in OAuth Server: Failed to complete OAuth handshake with Google. failed [400] {   "error" : "redirect_uri_mismatch" }

I checked the login url that is being generated by Asteroid:

https://accounts.google.com/AccountChooser?service=lso&continue=https%3A%2F%2Faccounts.google.com%2Fo%2Foauth2%2Fauth%3Fscope%3Dopenid%2Bemail%26response_type%3Dcode%26redirect_uri%3Dhttp%3A%2F%2Flocalhost%3A3000%2F_oauth%2Fgoogle%26state%3DeyJsb2dpblN0eWxlIjoicG9wdXAiLCJjcmVkZW50aWFsVG9rZW4iOiJlODk0N2M1MzVkYTZjMzg4NGUzM2MxYjVjZjQ5M2NhOCIsImlzQ29yZG92YSI6ZmFsc2V9%26client_id%3D60750537449-d2469pvur5lkfh4fs6cgo7q0100hk60g.apps.googleusercontent.com%26hl%3Den%26from_login%3D1%26as%3D-775f8062e42146ac&btmpl=authsub&hl=en

Compared to what is being generated by Meteor

https://accounts.google.com/AccountChooser?service=lso&continue=https%3A%2F%2Faccounts.google.com%2Fo%2Foauth2%2Fauth%3Fzt%3DChRQNW1LRng5NktlMFg0eHNhVUFQdRIfY3NvMDJ2NG1oOWtib2lJQmVPNlAybV9DR2JMa2t3SQ%25E2%2588%2599APsBz4gAAAAAVHdlnpuxD-W9_tPpKB5z3StCb_h4pCLI%26from_login%3D1%26hl%3Den%26as%3D-59273d9af2e8a0a5&btmpl=authsub&hl=en

I checked and the redirect_uri that is in the loginUrl generated by Asteroid is in my Google API configuration. (http://localhost:3000/_oauth/google)

First of all: Thank you so much for developing this project. I've read your blog post and I always felt exactly the same, not wanting to go for an all-in for Meteor, but rather use just the server part with a DDP connection to a client.

One thing I'd really like to use is offline storage, like they do in the Meteor world with Ground DB. Would something like this be possible with Asteroid?

I think some updates to how Meteor handles oauth might have messed things up for asteroid's Chrome platform loginWith methods. Asteroid.prototype._openOauthPopup expects token info from the tabs hash string but it seems like that hash no longer gets set for non-Cordova Meteor apps.

Might have a play around to see how far I get but thought of raising it up here. Awesome library by the way.

In your todo list demo you're using find and findOne methods on your collections, the latest version doesn't include these. Any reason for this?

http://docs.meteor.com/#publish_error

Can we have a hook to store and retrieve session variables.

http://docs.meteor.com/#/full/session_set

Do you have an example of how this could be achieved?

Thanks

Could be nice to get event only ddp message instead of collection related event.
I've been playing with stream ( http://arunoda.github.io/meteor-streams/ ) but I do not see how to make use of it as a agnostic meteor client.

thanks

I have a query like notifications.reactiveQuery({"read":false}), which returns records fine, when a record read attr changes to true (via a meteor.call 'clearNotification'), the query doesn't seem to catch the change. my current workaround is to rerun the query in the updated promise from my meteor.call method

I can tweak the read attr in the db and it works as you expect. not sure if its something i'm missing ?

var unreadNotificationQuery = notifications.reactiveQuery({"read":false});
  unreadNotificationQuery.on('change',function (change) {   
    console.log("change")
    $scope.notifications =  unreadNotificationQuery.result
    $scope.$apply()
  }) 

$scope.clearNotification = function(notification) {
    call = meteor.call('clearNotification',notification._id);    
    call.updated.then(function(){
      var q = notifications.reactiveQuery({"read":false});      
      $scope.notifications =  q.result 
      $scope.$apply() 
    })
  }

Hi,

I have a chrome extension that uses Twitter Sign in.
Also, I have a Meteor client that uses Twitter Sign in.

How can I sign in once and affect the other?

eg. I login on the meteor client and now the chrome extension is also logged.

Thank you.

Since in this 0.3.0 Version you put up a major change on Asteroid, could you redo the To Do app for the moment? I current have to read the asteroid test file to figure out the new updates

In the long run it will definitely update the document.

To fix the Meteor quirk

Use find instead of reactiveQuery, and return a cursor with fetch and observe methods.
