Amplify class (Amplify.ts) of aws-amplify unpredictable behaviour

[akasa9525]

I am using Node js - 8.11.3

var awsAmplify = require('aws-amplify');
    awsAmplify.configure({
          //
    });

throws me an error : awsAmplify.configure is not a function But we see in aws-amplify/packages/aws-amplify/src/Common/Amplify.ts at line 28, there is a static function by the name of configure.

I found that this issue is happening because, all the member functions oh the amplify class are wrapped in a json with key as default.

Amplify structure:

{ Analytics:
   AnalyticsClass {
     _config: {},
     _pluggables: [],
     _disabled: false,
     onHubCapsule: [Function] },

     API: APIClass { _api: null, _pubSub: null, _options: null },
     Storage: StorageClass { _options: null, vault: [Object], configure: [Function] },
     I18n:
      { [Function: I18n]
        configure: [Function],
        getModuleName: [Function],
        createInstance: [Function],
        setLanguage: [Function],
        get: [Function],
        putVocabulariesForLanguage: [Function],
        putVocabularies: [Function],
        checkConfig: [Function] },
     Cache:
      BrowserStorageCache {
        config: [Object],
        cacheCurSizeKey: 'aws-amplify-cacheCurSize',
        getItem: [Function: bound ],
        setItem: [Function: bound ],
        removeItem: [Function: bound ] },
     PubSub:
      PubSub {
        _options: null,
        _pluggables: [],
        subscribe: [Function: bound ] },
     Interactions: Interactions { _options: null, _pluggables: {} },
     Pushnotification: null,
     Logger: { [Function: ConsoleLogger] LOG_LEVEL: null },
     ServiceWorker: [Function: ServiceWorkerClass] } }

so for calling the configure function i had to use awsAmplify.default.configure()
We can remove this default wrapping around the members of amplify class.

@akasa9525 This is a expected behavior. Will this as documentation enhancement.

closing this and referencing in story for node support as we currently do not support running amplify in node
