title: How to add a url config file for Vue project
body: <p>Is there any possible to add a config file for Vue project to config API URL?</p>
  
  <p>Now I have a Vue web project, and a .Net Web API project.</p>
  
  <p>I have to build the web project every time that I have to publish to different environment.</p>
  
  <p>Is there any possible to add a config file like web.config for .Net Web API that I can edit it any time I want?</p>
  
  <p><strong><em>What I expected is, I can have a file to edit anytime I want after run command 'npm run build'. Is this possible</em></strong></p>
