I use Angular 5 AOT to build my website. It work well but It has low score on google spacespeed.
After I have spend lots of time to troubleshoot, I wonder why bundled js files are always at the bottom of index.html.
How do I bring those bundled js files to html header. It is the way to force bundled js files be downloaded first.

I believe it is better to leave the bundled js files at the bottom because they block parallel downloads.

  • If the page has plenty of images, browser downloads images first then it blocks bundled js files util downloading images finish. – R.Kaka Aug 17 '18 at 01:35
