Nginx config for multiple laravel sites based on /api/v1 url paths

nginx.conf

# This config will host your main [Laravel] GUI application at /, and any additional [Lumen] webservices at /api/v1 and /api/v2...
# This also works perfectly for all static file content in all projects
# This is full of debug comments so you can see how to print debug output to browser! Took me hours to nail this perfect config.

# Example:
# http://example.com - Main Laravel site as usual
# http://example.com/about - Main Laravel site about page as usual
# http://example.com/robots.txt - Main Laravel site static content as usual
# http://example.com/api/v1 - Lumen v1 api default / route
# http://example.com/api/v1/ - Lumen v1 api default / route
# http://example.com/api/v1/users - Lumen v1 api users route
# http://example.com/api/v1/robots.txt - Lumen v1 api static content
# http://example.com/api/v2 - Lumen v2 api default / route
# http://example.com/api/v2/ - Lumen v2 api default / route
# http://example.com/api/v2/users - Lumen v2 api users route
# http://example.com/api/v2/robots.txt - Lumen v2 api static content
