Official Push adapter for parse-server
If you have migrated from parse.com and you are seeing situations where silent (newsstand-like presentless) notifications are failing to deliver please ensure that your payload is setting the content-available attribute to Int(1) and not "1" This value will be explicitly checked.
You can enable verbose logging with environment variables:
VERBOSE=1 or VERBOSE_PARSE_SERVER_PUSH_ADAPTER=1
This will produce a more verbose output for all the push sending attempts
