- Support YAML configuration.
- Support command line to send single Android or iOS notification.
- Support Web API to send push notification.
- Support graceful restart & zero downtime deploy using facebook grace.
- Support HTTP/2 or HTTP/1.1 protocol.
- Support notification queue and multiple workers.
- Support
/api/stat/appshow notification success and failure counts. - Support
/api/configshow your YAML config. - Support store app stat to memory, Redis, BoltDB, BuntDB, LevelDB or BadgerDB.
- Support
p8,p12orpemformat of iOS certificate file. - Support
/sys/statsshow response time, status code count, etc. - Support for HTTP proxy to Google server (FCM).
- Support retry send notification if server response is fail.
- Support expose prometheus metrics.
- Support install TLS certificates from Let's Encrypt automatically.
- Support send notification through RPC protocol, we use gRPC as default framework.
- Support running in Docker, Kubernetes or AWS Lambda (Native Support in Golang)

brew install --HEAD https://github.com/appleboy/gorush/raw/master/HomebrewFormula/gorush.rbGorush uses the Go Modules support built into Go 1.11 to build. The easiest way to get started is to clone Gorush in a directory outside of the GOPATH, as in the following example:
mkdir $HOME/src
cd $HOME/src
git clone https://github.com/appleboy/gorush.git
cd gorush

}The following payload asks the system to display an alert with a Close button and a single action button.The title and body keys provide the contents of the alert. The “PLAY” string is used to retrieve a localized string from the appropriate Localizable.strings file of the app. The resulting string is used by the alert as the title of an action button. This payload also asks the system to badge the app’s icon with the number 5.
