Process.env variables inside index.html

Created by: CodeJjang

I've read the docs thoroughly as well as issues here and haven't found such a suggestion.

How about injecting the process.env values to index.html too, just like PUBLIC_URL is being injected?

It's useful in cases you want to must embed variables (like API keys) in a script tag, e.g. when using react-google-autocomplete and you have to put the following in index.html:

 <script type="text/javascript"
            src="https://maps.googleapis.com/maps/api/js?key=%SOME_ENV_VARIABLE%&libraries=places"/>

I know I can do it by ejecting and adding parameters to webpack config, but I thought there should be a better way to perform this without ejecting.

Thanks
