Hi

There are different ways to do it. 

One way is to load the api defintion with a script tag

<script src="http://app.domain.com/api.js"></script>

and then configure the Direct Manager

 Ext.direct.Manager.addProvider(Ext.app.REMOTING_API);

Or when you only have a few ext.direct server methods you can hardcode the definitions

 Ext.direct.Manager.addProvider({  
                    "url" : "http://app.domain.com/router",  
                    "type" : "remoting",  
                    "actions" : {
                          "logService" : [ { "name" : "log", "len" : 1 } ],
                          "navigationService" : [ {"name" : "getNavigation", "len" : 1} ]
                    });

In Ext Js 5 and 6 there is another way. With the function loaderProvider

 Ext.direct.Manager.loadProvider({
     url: 'http://app.domain.com/api.js',
     varName: 'Ext.app.REMOTING_API' 
 });

Here is an interesting blog about loading the ext direct api

Hi

Not sure why you want to change the type. But you can do that. You have to make sure that you write an implementation 

of the provider and the alias matches the type config 

type: 'rpc'   -->    alias: 'direct.rpcprovider'

Here is the source code of the remoting provider (type: 'remoting'): 

http://docs.sencha.com/extjs/6.0/6.0.0-classic/source/RemotingProvider.html#Ext-direct-RemotingProvider

What happens when you call the service? Make sure that the number of arguments matches the len config

For instance (len = 1)

logService.log(parm1, function() {

  //callback

});
