rb-go / go-fcm

Optimized Firebase Cloud Messaging Package for Golang

gofcm

(in beta but works in production :) )

This project basicly was forked from github.com/appleboy/go-fcm.

Difference with appleboy package

• Go modules with semantic versioning
• valyala/fasthttp client instead of net/http
• mailru/easyjson client instead of encoding/json
• Send() returns original body ([]byte) too (if FCM answer changed you can parse by yourself and not wait for package update)
• Some optimizations

Golang client library for Firebase Cloud Messaging. Implemented only HTTP client.

Getting Started

go get github.com/riftbit/gofcm

Sample Usage

Here is a simple example illustrating how to use FCM library:

package main

import (
	"log"

	"github.com/riftbit/gofcm"
)

func main() {
	// Create the message to be sent.
	msg := &fcm.Message{
		To: "sample_device_token",
		Data: map[string]interface{}{
			"foo": "bar",
		},
	}

	// Create a FCM client to send the message.
	client, err := fcm.NewClient("sample_api_key")
	if err != nil {
		log.Fatalln(err)
	}

	// Send the message and receive the response without retries.
	response, body, err := client.Send(msg)
	if err != nil {
		log.Fatalln(err)
	}

	log.Printf("%#v\n", response)
	log.Printf("%#v\n", body)
}
