.htaccess and proxy settings for routing a decoupled REST API consuming theme

Ok this probably has a superfluous few lines but this works for me:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^static/(.*)$ /wp-content/themes/MYTHEME/static/$1 [R=301,NC,L]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
