title: How to package, or import Html-Templates without Html-Imports
body: <p>Since Html-Imports are now deprecated in Chrome (<a href="https://www.chromestatus.com/feature/5144752345317376" rel="noreferrer">https://www.chromestatus.com/feature/5144752345317376</a>) and will be removed, I wonder what the alternatives are.</p>
  
  <p>I'm currently using Html-Imports to import Html-Templates. I see only two alternatives so far:</p>
  
  <ul>
  <li>Bundling all HTML-files together in one file. This would also improve donwload times in production, but this would decrease encapsulation and modularization. There is a polymer-bundler that would do the job by traversing the HTML-Import-Statements in separated HTML-Files. But this would mean, that HTML-Imports remain in my Code even if they are not supported by any Browsers in future.</li>
  <li>Building some kind of module loader using XHttpRequests and knitting the templates into one HTML-File at runtime. This would preserve encapsulation and modularization, but this has a bad smell to me since I would basically rebuild the import-Statements on my own.</li>
  </ul>
  
  <p>Is there a new vanilla way to import Html-Templates? (By "vanilla" I basically mean a way without any additional tools like precompiler or bundler involved)</p>
