strfry-evsifter

A tiny framework for writing strfry's event sifter (write policy) plugin in Go.

Installation

go get github.com/jiftechnify/strfry-evsifter

Example

The same logic as the example implemented using this framework.

package main


import (
	"log"

	evsifter "github.com/jiftechnify/strfry-evsifter"
)

var whiteList = map[string]struct{}{
    "003ba9b2c5bd8afeed41a4ce362a8b7fc3ab59c25b6a1359cae9093f296dac01": {},
}

// event-sifting function
func acceptWhiteListed(input *evsifter.Input) (*evsifter.Result, error) {
	if _, ok := whiteList[input.Event.PubKey]; ok {
        return input.Accept()
	}

    // you can emit arbitrary logs by log.Print() family
    log.Println("blocking event!")
    return input.Reject("blocked: not on white-list")
}

func main() {
    // initialize a evsifter.Runner and set an event-sifting function
    var s evsifter.Runner
    s.SiftWithFunc(acceptWhiteListed)

    // start the event sifter routine
    s.Run()
}
