YoMo

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.

🚀 Getting Started

1. Install CLI

# Ensure use $GOPATH, golang requires main and plugin highly coupled
○ echo $GOPATH

if $GOPATH is not set, check Set $GOPATH and $GOBIN first.

$ GO111MODULE=off go get github.com/yomorun/yomo

$ cd $GOPATH/src/github.com/yomorun/yomo

$ make install

2. Create your serverless app

$ mkdir -p $GOPATH/src/github.com/{YOUR_GITHUB_USERNAME} && cd $_

$ yomo init yomo-app-demo
2020/12/29 13:03:57 Initializing the Serverless app...
2020/12/29 13:04:00 ✅ Congratulations! You have initialized the serverless app successfully.
2020/12/29 13:04:00 🎉 You can enjoy the YoMo Serverless via the command: yomo dev

$ cd yomo-app-demo

CLI will automatically create the app.go:

package main

import (
	"context"
	"fmt"
	"time"

	"github.com/yomorun/yomo/pkg/rx"
)

var printer = func(_ context.Context, i interface{}) (interface{}, error) {
	value := i.(float32)
	fmt.Println("serverless get value:", value)
	return value, nil
}

// Handler will handle data in Rx way
func Handler(rxstream rx.RxStream) rx.RxStream {
	stream := rxstream.
		Y3Decoder("0x10", float32(0)).
		AuditTime(100 * time.Millisecond).
		Map(printer).
		StdOut()

	return stream
}

3. Build and run

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

Congratulations! You have done your first YoMo application.

Optional: Set $GOPATH and $GOBIN

for current session:

export GOPATH=~/.go
export PATH=$GOPATH/bin:$PATH

for shell:

for zsh users

echo "export GOPATH=~/.go" >> .zshrc
echo "path+=$GOPATH/bin" >> .zshrc

for bash users

echo 'export GOPATH=~/.go' >> .bashrc
echo 'export PATH="$GOPATH/bin:$PATH"' >> ~/.bashrc

🎯 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 yomo-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
