micro

Micro - the serverless Go functions framework

Usage

A simple timer trigger:

import "git.sr.ht/~louis77/micro"

func myFunc(payload *string, log *log.Logger) (*string, error) {
    // Run any code here
    // Log output to log interface,
    // will be pushed to console and eventservice, if configured
    //
    // Return *string for Trigger which support returning a result
    // like HTTPTrigger
    // Return err if execution failed. Error will be logged and
    // Triggers can decide how to handle
}

func main() {
    micro.NewTimerTrigger("0 0 12 * * *", myFunc)
    micro.Start()
}

import "git.sr.ht/~louis77/micro"

func import(provider string) micro.Func {
  return func (log *log.Logger) {
  }
}

func main() {
	eventservice, err := eventers.NewPGClient(os.Getenv("DATABASE_URL"))
    if err != nil {
        t.Error(err)
    }
    SetEventer(eventservice)
	
    micro.NewTimerTrigger("0 0 12 * * *", import("providerA"), "import")
    micro.NewTimerTrigger("0 0 14 * * *", import("providerB"), "import")
    
	// Start triggers and continue, or...
	micro.Start()
	
	// Start triggers and a HTTP listener
	micro.StartAndListen(os.Getenv("PORT"))
}

Eventservices

Currently, there is one event service logger which supports logging to a Postgres database table. Micro provides the Eventer interface which will allow you to write your own event service loggers.

type Eventer interface {
	PushEvent(class string, startTime, endTime time.Time, output string, err error) error
}

Roadmap

• Add function chaining
• Add more trigger types
• PGClient should create schema automatically
• PGClient should dynamically accept table name
