YoMo is an open-source Streaming Serverless Framework for building Low-latency Edge Computing applications. Built atop QUIC Transport Protocol and Functional Reactive Programming interface. makes real-time data processing reliable, secure, and easy.

Official Website: 🦖


🌶 Features

⚡️ Low-latency Guaranteed by implementing atop QUIC QUIC
🔐 Security TLS v1.3 on every data packet by design
📱 5G/WiFi-6 Reliable networking in Celluar/Wireless
ğŸŒŽ Geo-Distributed Edge Mesh Edge-Mesh Native architecture makes your services close to end users
📸 Event-First Architecture leverages serverless service to be event driven and elastic
🦖 Streaming Serverless Write only a few lines of code to build applications and microservices
🚀 Y3 a faster than real-time codec
📨 Reactive stream processing based on Rx

🚀 Getting Started


Install Go

1. Install CLI

$ go install[email protected]

Verify if the CLI was installed successfully

$ yomo -V

YoMo CLI version: v0.0.6

2. Create your serverless app

$ yomo init yomo-app-demo

⌛  Initializing the Serverless app...
✅  Congratulations! You have initialized the serverless function successfully.
ℹ️   You can enjoy the YoMo Serverless via the command: 
ℹ️   	DEV: 	yomo dev -n Noise yomo-app-demo/app.go
ℹ️   	PROD: 	First run source application, eg: go run example/source/main.go
		Second: yomo run -n yomo-app-demo yomo-app-demo/app.go

$ cd yomo-app-demo

CLI will automatically create the app.go:

package main

import (

	y3 ""

// NoiseDataKey represents the Tag of a Y3 encoded data packet
const NoiseDataKey = 0x10

// NoiseData represents the structure of data
type NoiseData struct {
	Noise float32 `y3:"0x11"`
	Time  int64   `y3:"0x12"`
	From  string  `y3:"0x13"`

var printer = func(_ context.Context, i interface{}) (interface{}, error) {
	value := i.(NoiseData)
	rightNow := time.Now().UnixNano() / int64(time.Millisecond)
	fmt.Println(fmt.Sprintf("[%s] %d > value: %f ⚡️=%dms", value.From, value.Time, value.Noise, rightNow-value.Time))
	return value.Noise, nil

var callback = func(v []byte) (interface{}, error) {
	var mold NoiseData
	err := y3.ToObject(v, &mold)
	if err != nil {
		return nil, err
	mold.Noise = mold.Noise / 10
	return mold, nil

// Handler will handle data in Rx way
func Handler(rxstream rx.RxStream) rx.RxStream {
	stream := rxstream.

	return stream

3. Build and run

  1. Run yomo dev from the terminal. you will see the following message:
$ yomo dev

ℹ️   YoMo serverless function file: app.go
⌛  Create YoMo serverless instance...
⌛  YoMo serverless function building...
✅  Success! YoMo serverless function build.
ℹ️   YoMo serverless function is running...
ℹ️   Run: /Users/xiaojianhong/Downloads/yomo-app-demo/sl.yomo

ğŸŽ¯ Focuses on computings out of data center

  • IoT/IIoT/AIoT
  • Latency-sensitive applications.
  • Networking situation with packet loss or high latency.
  • Handling continuous high frequency generated data with stream-processing.
  • Building Complex systems with Streaming-Serverless architecture.

🌟 Why YoMo

  • Based on QUIC (Quick UDP Internet Connection) protocol for data transmission, which uses the User Datagram Protocol (UDP) as its basis instead of the Transmission Control Protocol (TCP); significantly improves the stability and throughput of data transmission. Especially for cellular networks like 5G.
  • A self-developed y3-codec optimizes decoding performance. For more information, visit its own repository on GitHub.
  • Based on stream computing, which improves speed and accuracy when dealing with data handling and analysis; simplifies the complexity of stream-oriented programming.
  • Secure-by-default from transport protocol.

🦸 Contributing

First off, thank you for considering making contributions. It's people like you that make YoMo better. There are many ways in which you can participate in the project, for example:

  • File a bug report. Be sure to include information like what version of YoMo you are using, what your operating system is, and steps to recreate the bug.
  • Suggest a new feature.
  • Read our contributing guidelines to learn about what types of contributions we are looking for.
  • We have also adopted a code of conduct that we expect project participants to adhere to.
