title: Angular 2 - building "dist" for production using "npm", and not "ng build -prod"
body: <p>I have a project that I am building and running with <code>npm start</code> instead of <code>ng serve</code>. I am an angular 2 beginner, so I don't know how to build this project for production, in order to have the <code>dist/</code> folder with pure javascript/html/css in it. For <code>ng init</code> - created angular 2 apps, if I use <code>ng</code> command, I can just do <code>ng build --prod</code> when work is done and the <code>dist</code> folder is created. If I use <code>ng build --prod</code> on this project, angular is offering me to overwrite some of my files (app.module.ts, app.component.ts, etc....) which I don't want overwritten. There are routing things inside and I don't want to change them. How can I have the production version of this app (ie. the dist/ folder) without using the <code>ng build --prod</code> command? Angular-cli version is:</p>
  
  <pre><code>angular-cli: 1.0.0-beta.28.3
  </code></pre>
