I would like to add some options to the header in the index.html file. I know I can append the header with jquery and javascript but that fires too late. I'm trying to add some Facebook meta data. Facebook scrapes just the header for this data so by the time javascript kicks in Facebook has already finished.
Outside of manually editing the index.html file every time I export how can I add items to the header?
Example of what I would like to add to the header of the index.html file.
<meta property="og:title" content="Hello World">
