title: Angular 7 library html-template changes are not affected into application when concurrently running ng build --watch and ng serve
body: <p>Angular 7 library html-template changes are not affected into Angular application when they are running concurrently in different cmd using "ng build library --watch" and "ng serve application".</p>
  
  <p>So I first start library with watch flag on, then I start application with ng serve. Changes in library into ts files will start HMR on application and changes are affected correctly. But when I change some components html or css files HMR will detect change and start to update application but changes are not seen in UI. If I stop ng serve and start it again then those html and css changes are affected into UI.</p>
  
  <p>I have checked that changes are affected to dist directory where library build will but output files. So somehow ng serve will not take them even it notice them.</p>
  
  <p>I refer to library using tsconfig.json paths. Because baseUrl for my application is src I need to use ../ in configuration like this</p>
  
  <pre><code>"@lw/common": [
      "../dist/@lw/common"
    ]
  </code></pre>
  
  <p>I use @ in deploy path because I need to import scss files from library. This way import path is same if I install this package from npm. So configuration what I am looking for is to ease library development by using --watch mode.</p>

      @lw
          common
  projects
      lw
          common

  <p>EDIT: This problem was already reported in Angular cli github repo <a href="https://github.com/angular/angular-cli/issues/13588" rel="nofollow noreferrer">https://github.com/angular/angular-cli/issues/13588</a> So it is bug in cli.</p>
