how to eliminate the render blocking in angular-cli site?

after running ng build --prod I can go into my index.html file in the newly created dist folder and add the async attribute to the bundled script tags to keep them from being blocking. this helps with website speed but sporadically crashes the site. is there an option in the angular-cli.json that would add this for me during the build in a better way? i ran my site through google's test my website and the only thing i have left to fix is Eliminate render-blocking JavaScript and in above-the-fold content
