Importing Boostrap4 into angular2 CLI

Question

I am learning Angular2 CLI into my http://localhost:4200/. I followed https://cli.angular.io/ the tutorial and installed Angular2 successfully.

I have the problem with importing bootstrap4 css in this. I have tried the following code into my src/angular.json file.

"assets": [
  "src/favicon.ico",
  "src/assets"
],
"styles": [
  "src/styles.css",
  "src/assets/css/bootstrap.min.css",
  "src/assets/css/style.css"
],
"scripts": [
  "src/assets/js/jquery.min.js",
  "src/assets/js/bootstrap.min.js"
],

I have added the bootstrap sample navbar into my app.component.html

<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav mr-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>      
    </ul>
  </div>
</nav>

I am getting the [WDS] Disconnected! error in my local.

I have tried adding import 'src/assets/css/bootstrap.css'; into my style.css but its working as a inline style not getting desired output.

If I tried to include index.html header using <link src="" its working but I don't want to use this method. Any help will be appreciated. Thanks in Advance.

Try this command,

npm install bootstrap@4 jquery --save 

After edit the Angular.json file modify `"style"

["node_modules/bootstrap/dist/css/bootstrap.css"]`

&

"script:["/node_modules/jquery/dist/jquery.js"]`and ["node_modules/bootstrap/dist/ js/boostrap.js"`]
