angular-xmpp-services

This is a library talks to a xmpp server and generates a model { dynamic json }, ready to use for controllers and directives. Serverside xmpp_ftw is needed.

The library sends and receives xmpp stanzas. Based on these messages a model (json tree) is build. The lib also handels the render timing by sending promise notify messages. https://docs.angularjs.org/api/ng/service/$q

• No $rootScope messaging needed
• ready to use automatic updating model
• easy to use API

#install

#getting started

Command list: xmpp-ftw-core

    //to use this lib we need a server with xmpp-ftw
    var host="http://laos.buddycloud.com/";
    $scope.xmpp=new Xmpp(host);

    //Here is the angular magic. 
    //If the model has changed and needs rerender, 
    //the factory will trigger the digest cycle by sending a notification
    $scope.xmpp.watch().then(function(data){
        console.log("disconnect - you have to login again");
    },function(error){
        console.log(error);
    },function(notification){
        console.log("notification",notification);
        //$scope.$apply() not needed,empty function fires render process
    });

    //login (please don't change the password)
    $scope.xmpp.send('xmpp.login',{
         "jid": "[email protected]",
         "password": "nix"
    }).then(function(){
        $scope.xmpp.send("xmpp.roster.get")
        $scope.xmpp.send("xmpp.presence")
    });

##The Model angular-xmpp-services sends your commands directly to xmpp-ftw. The xmpp traffic is monitored and a model (json tree) is generated. The model is updated automaticaly and the changes will be rendered by angular. ###me $scope.xmpp.model.me

{
  "status": "online",
  "jid": {
    "local": "robotnic",
    "domain": "laos.buddycloud.com",
    "resource": "angular-xmpp",
    "user": "robotnic"
  }
}

plunker

You can change the {{xmpp.model.me}} to an other value to explore the model.

template

<div>user: {{xmpp.model.me.jid.user}}</div>
<div>domain: {{xmpp.model.me.jid.domain}}</div>
<div>{{xmpp.model.me.status}}"</div>

roster with presence

 <div ng-repeat="item in xmpp.model.roster">
    <div ng-if="item.presence" class="status online"></div>
    <div ng-if="!item.presence" class="status offline"></div>
    {{item.jid.user}}@{{item.jid.domain}}
    <p class="statustext">{{item.presence.status}}</p>
  </div>

#Directives

If you are looking for a ready to use directive collection, this is the place to go: angular-xmpp

Here we learn how to make directives

structure

There is an outer <xmpp></xmpp> that containes the other directives. It provides xmpp core https://xmpp-ftw.jit.su/manual/core/ The inner directives share the same instance of the XmppCore Factory.

<xmpp host="https://laos.buddycloud.com" domain="laos.buddycloud.com">
    <xmpplogin></xmpplogin>
    <xmpproster></xmpproster>
    <xmppminichat></xmppminichat>
    <xmppmycoolapp></xmppmycoolapp>
</xmpp>

        'scope': {
            oninit:'&oninit'

            xmppController.on("connected",function(event,status){
