A live demo on Netlify.

Features

• Support Firebase Cloud Messaging using go-fcm library for Android.
• Support HTTP/2 Apple Push Notification Service using apns2 library.
• Support HMS Push Service using go-hms-push library for Huawei Devices.
• Support YAML configuration.
• Support command line to send single Android or iOS notification.
• Support Web API to send push notification.
• Support HTTP/2 or HTTP/1.1 protocol.
• Support notification queue and multiple workers.
• Support /api/stat/app show notification success and failure counts.
• Support /api/config show your YAML config.
• Support store app stat to memory, Redis, BoltDB, BuntDB, LevelDB or BadgerDB.
• Support p8, p12 or pem format of iOS certificate file.
• Support /sys/stats show response time, status code count, etc.
• Support for HTTP, HTTPS or SOCKS5 proxy.
• Support retry send notification if server response is fail.

      "tokens": ["token_a", "token_b"],
      "platform": 1,
      "message": "Hello World iOS!"
    }
  ]
}

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.

{
  "notifications": [
    {
      "tokens": ["token_a", "token_b"],
      "platform": 1,
      "badge": 5,
      "alert": {
        "title" : "Game Request",
        "body" : "Bob wants to play poker",
        "action-loc-key" : "PLAY"
      }
    }
  ]
}

The following payload specifies that the device should display an alert message, plays a sound, and badges the app’s icon.

{
  "notifications": [
    {

Response body

Error response message table:

status code	message
400	Missing notifications field.
400	Notifications field is empty.
400	Number of notifications(50) over limit(10)

Success response:

{
  "counts": 60,
  "logs": [],
  "success": "ok"
}

If you need error logs from sending fail notifications, please set a feedback_hook_url. The server with send the failing logs asynchronously to your API as POST requests.

core:
  port: "8088" # ignore this port number if auto_tls is enabled (listen 443).
  worker_num: 0 # default worker number is runtime.NumCPU()
  queue_num: 0 # default queue number is 8192
  max_notification: 100
  sync: false
- feedback_hook_url: ""
+ feedback_hook_url: "https://exemple.com/api/hook"

You can also switch to sync mode by setting the sync value as true on yaml config.

core:
  port: "8088" # ignore this port number if auto_tls is enabled (listen 443).
  worker_num: 0 # default worker number is runtime.NumCPU()
  queue_num: 0 # default queue number is 8192
  max_notification: 100
- sync: false
+ sync: true

See the following error format.

{
  "counts": 60,
  "logs": [
    {
      "type": "failed-push",
      "platform": "android",
      "token": "*******",
      "message": "Hello World Android!",
      "error": "InvalidRegistration"
    },
    {
      "type": "failed-push",
      "platform": "ios",
      "token": "*****",
      "message": "Hello World iOS1111!",
      "error": "Post https://api.push.apple.com/3/device/bbbbb: remote error: tls: revoked certificate"
    },
    {
      "type": "failed-push",
      "platform": "ios",
      "token": "*******",
      "message": "Hello World iOS222!",
      "error": "Post https://api.push.apple.com/3/device/token_b: remote error: tls: revoked certificate"
    }
  ],
  "success": "ok"
}

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"

	structpb "github.com/golang/protobuf/ptypes/struct"
	"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",
		Badge:    1,
		Category: "test",
		Sound:    "test",
		Priority: proto.Priority_High,
		Alert: &proto.Alert{
			Title:    "Test Title",
			Body:     "Test Alert Body",
			Subtitle: "Test Alert Sub Title",
			LocKey:   "Test loc key",
			LocArgs:  []string{"test", "test"},
		},
		Data: &structpb.Struct{
			Fields: map[string]*structpb.Value{
				"key1": {
					Kind: &structpb.Value_StringValue{StringValue: "welcome"},
				},
				"key2": {
					Kind: &structpb.Value_NumberValue{NumberValue: 2},
				},
			},
		},
	})
	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();
  var alert = new messages.Alert();
  request.setPlatform(2);
  request.setTokensList(["1234567890"]);
  request.setMessage("Hello!!");
  request.setTitle("hello2");
  request.setBadge(2);
  request.setCategory("mycategory");
  request.setSound("sound")
  alert.setTitle("title");
  request.setAlert(alert);
  request.setThreadid("threadID");
  request.setContentavailable(false);
  request.setMutablecontent(false);
  client.send(request, function (err, response) {
    if(err) {
      console.log(err);
    } else {
      console.log("Success:", response.getSuccess());
      console.log("Counts:", response.getCounts());
    }
  });
}

main();

Run gorush in Docker

Set up gorush in the cloud in under 5 minutes with zero knowledge of Golang or Linux shell using our gorush Docker image.

docker pull appleboy/gorush
docker run --name gorush -p 80:8088 appleboy/gorush

Run gorush with your own config file.

docker pull appleboy/gorush
docker run --name gorush -v ${PWD}/config.yml:/config.yml -p 80:8088 appleboy/gorush

Testing your gorush server using httpie command.

http -v --verify=no --json GET http://your.docker.host/api/stat/go

Run gorush in Kubernetes

Quick Start

Create namespace as gorush as gorush and then your configuration map:

kubectl create -f k8s/gorush-namespace.yaml
kubectl create -f k8s/gorush-configmap.yaml

Create redis service:

kubectl create -f k8s/gorush-redis-deployment.yaml
kubectl create -f k8s/gorush-redis-service.yaml

Create gorush deployment controller provides declarative updates for Pods and ReplicaSets:

kubectl create -f k8s/gorush-deployment.yaml

Create the Service Controller for AWS ELB

kubectl create -f k8s/gorush-service.yaml

Ingress Controller for AWS ALB

Update the following in k8s/gorush-service.yaml

-  type: LoadBalancer
-  # type: NodePort
+  # type: LoadBalancer
+  type: NodePort

Then start the AWS ALB by the follwong command.

kubectl create -f k8s/gorush-service.yaml
kubectl create -f k8s/gorush-aws-alb-ingress.yaml

Clean up the gorush:

kubectl delete -f k8s

Run gorush in AWS Lambda

AWS excited to announce Go as a supported language for AWS Lambda. You’re going to create an application that uses an API Gateway event source to create a simple Hello World RESTful API.

Build gorush binary

Download source code first.

git clone https://github.com/appleboy/gorush.git
cd gorush && make build_linux_lambda

you can see the binary file in release/linux/lambda/ folder

Deploy gorush application

we need to build a binary that will run on Linux, and ZIP it up into a deployment package.

zip deployment.zip release/linux/lambda/gorush

Upload the deployment.zip via web UI or you can try the drone-lambda as the following command. it will zip your binary file and upload to AWS Lambda automatically.

$ AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY_ID \
  AWS_SECRET_ACCESS_KEY=YOUR_AWS_SECRET_ACCESS_KEY \
  drone-lambda --region ap-southeast-1 \
  --function-name gorush \
  --source release/linux/lambda/gorush

Without an AWS account

Or you can deploy gorush to alternative solution like netlify functions. Netlify lets you deploy serverless Lambda functions without an AWS account, and with function management handled directly within Netlify. Please see the netlify.toml file:

[build]
  command = "./build.sh"
  functions = "release/linux/lambda"

[build.environment]
  GO_IMPORT_PATH = "github.com/appleboy/gorush"
  GO111MODULE = "on"

[[redirects]]
  from = "/*"
  to = "/.netlify/functions/gorush/:splat"
  status = 200
