Prerequisite Tools

Fetch from GitHub

Gorush 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
go install

or you can use the go get command to install the latest or specific version.

Note: such go get installation aren't guaranteed to work. We recommend using binary installation.

# install stable version
go install github.com/appleboy/gorush

# install latest version
go install github.com/appleboy/gorush@master

Send Android notification

To authenticate a service account and authorize it to access Firebase services, you must generate a private key file in JSON format.

  1. In the Firebase console, open Settings > Service Accounts.
  2. Click Generate New Private Key, then confirm by clicking Generate Key.
  3. Securely store the JSON file containing the key.

When authorizing via a service account, you have two choices for providing the credentials to your application. You can either set the GOOGLE_APPLICATION_CREDENTIALS environment variable, or you can explicitly pass the path to the service account key in code. The first option is more secure and is strongly recommended.

Send single notification with the following command.

gorush -android -m "your message" --fcm-key "FCM Credentials Key Path" -t "device token"

# or set GOOGLE_APPLICATION_CREDENTIALS environment variable
export GOOGLE_APPLICATION_CREDENTIALS="FCM Credentials Key Path"
gorush -android -m "your message" -t "device token"

Send messages to topics.

gorush --android --topic "foo-bar" \
  -m "This is a Firebase Cloud Messaging Topic Message" \
  --fcm-key "FCM Credentials Key Path"

Send Huawei (HMS) notification

Send single notification with the following command.

gorush -huawei -title "Gorush with HMS" -m "your message" -hk "API Key" -hid "App ID" -t "Device token"

Send messages to topics.

gorush --huawei --topic "foo-bar" \
  -title "Gorush with HMS" \
  -m "This is a Huawei Mobile Services Topic Message" \
  -hk "API Key" \
  -hid "App ID"

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"

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

Send Android or iOS notifications using Firebase Cloud Messaging

Send single notification with the following command:

gorush -android -m "your message" \
  --fcm-key "FCM Credentials Key Path" \
  -t "Device token"

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 and feedback_header for custom header. 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"
+ feedback_header:
+   - x-gorush-token:4e989115e09680f44a645519fed6a976

You can also switch to sync mode by setting the sync value as true on yaml config. It only works when the queue engine is local.

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.NewClient(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.NotificationRequest_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.Println("could not greet: ", err)
  }

  if r != nil {
    log.Printf("Success: %t\n", r.Success)
    log.Printf("Count: %d\n", r.Counts)
  }
}

See the Node.js example and see more detail from 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 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

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 = "make build_linux_lambda"
functions = "release/linux/lambda"

[build.environment]
GO111MODULE = "on"
GO_IMPORT_PATH = "github.com/appleboy/gorush"
GO_VERSION = "1.21.11"

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