Modify module with plugins when Typescript definition split across multiple files -

in typescript 2.2 i'm trying define module (hapijs) has various plugin options.

i refactored core code multiple .d.ts files , imported , re-exported them index.d.ts using following pattern (as seen here):

export * './hapi/connection'; export * './hapi/reply'; export * './hapi/request'; export * './hapi/response'; export * './hapi/route'; export * './hapi/server_views'; export * './hapi/server'; 

in separate module, extends them as seen here:

import * hapi 'hapi';  declare module 'hapi' {     interface ifilehandler {         /** path - path string or function described above (required). */         path: string | irequesthandler<string>;         ...     }      // extending hapi core:     interface irouteconfiguration {         file?: string | irequesthandler<string> | ifilehandler; 

however when did references irequesthandler above error with: "cannot find name 'irequesthandler'.". if hapi code moved 1 giant index.d.ts works expected. there way achieve using multiple hapi definition files?

i haven't tried out perhaps might possible use following (though doubt interface hapi.irouteconfiguration { acceptable):

import * hapi 'hapi';  declare module 'hapi' {     interface ifilehandler {         /** path - path string or function described above (required). */         path: string | hapi.irequesthandler<string>;         ...     }      // extending hapi core:     interface hapi.irouteconfiguration {         file?: string | hapi.irequesthandler<string> | ifilehandler;'; 

alternatively perhaps importing hapi/server, or whichever part needed.
