title: How to export functions in shared.module?
body: <p>I have the following function:</p>
  <pre><code>export function toCamelCase(string): string {
    //code omitted
  }
  </code></pre>
  <p>Then I use it on my feature components by adding reference as:</p>
  <pre><code>import * as utility from '../shared/functions/helper-functions';
  </code></pre>
  <p>However, I use a shared module and I am wondering if it is possible to add this helper function reference only to shared module and export it so that I can use its functions without adding its reference (I already add shared.module reference). Any idea?</p>
  <pre><code>import * as utility from '../shared/functions/helper-functions';
  
  @NgModule({
    declarations: [
      //...
    ],
    imports: [
      //...
    ],
    exports:  [
      // I want to add helper function as a module    
    ],
    providers: [
      //...
  })
  export class SharedModule { }
  </code></pre>
