$ gorush --android --topic "/topics/foo-bar" \
  -m "This is a Firebase Cloud Messaging Topic Message" \
  -k your_api_key

-m: Notification message.
-k: Firebase Cloud Messaging api key
-t: Device token.
--title: Notification title.
--topic: Send messages to topics. note: don't add device token.
--proxy: Set http proxy url. (only working for FCM)

Send iOS notification

Send single notification with the following command.

$ gorush -ios -m "your message" -i "your certificate path" \
  -t "device token" --topic "apns topic"

-m: Notification message.
-i: Apple Push Notification Certificate path (pem or p12 file).
-t: Device token.
--title: Notification title.
--topic: The topic of the remote notification.
--password: The certificate password.

The default endpoint is APNs development. Please add -production flag for APNs production push endpoint.

$ gorush -ios -m "your message" -i "your certificate path" \
  -t "device token" \
  -production

Run gorush web server

Please make sure your config.yml exist. Default port is 8088.

# for default config
$ gorush
# for custom config file
$ gorush -c config.yml

Get go status of api server using httpie tool:

$ http -v --verify=no --json GET http://localhost:8088/api/stat/go

Run gRPC service

Gorush support gRPC service. You can enable the gRPC in config.yml, default as disabled. Enable the gRPC server:

$ GORUSH_GRPC_ENABLED=true GORUSH_GRPC_PORT=3000 gorush

The following example code to send single notification in Go.

package main

import (
	"context"
	"log"

	"github.com/appleboy/gorush/rpc/proto"

	"google.golang.org/grpc"
)

const (
	address = "localhost:9000"
)

func main() {
	// Set up a connection to the server.
	conn, err := grpc.Dial(address, grpc.WithInsecure())
	if err != nil {
		log.Fatalf("did not connect: %v", err)
	}
	defer conn.Close()
	c := proto.NewGorushClient(conn)

	r, err := c.Send(context.Background(), &proto.NotificationRequest{
		Platform: 2,
		Tokens:   []string{"1234567890"},
		Message:  "test message",
	})
	if err != nil {
		log.Fatalf("could not greet: %v", err)
	}
	log.Printf("Success: %t\n", r.Success)
	log.Printf("Count: %d\n", r.Counts)
}

See the Node.js example and see more detail frome README:

var messages = require('./gorush_pb');
var services = require('./gorush_grpc_pb');

var grpc = require('grpc');

function main() {
  var client = new services.GorushClient('localhost:9000',
    grpc.credentials.createInsecure());
  var request = new messages.NotificationRequest();
  request.setPlatform(2);
  request.setTokensList(["1234567890"]);
  request.setMessage("Hello!!");
  client.send(request, function (err, response) {
    console.log('Success:', response.getSuccess());
    console.log('Counts:', response.getCounts());
  });
}

main();

GRPC Health Checking example: See document.

package main

import (
	"context"
	"log"

	"github.com/appleboy/gorush/rpc/proto"

	"google.golang.org/grpc"
