Event Logger

This package provides a simple interface for event logging to generic backends as well as a solid set of backend implementations.

Available Storage Backends

• csv: logging events in CSV format, easy for development and log collection
• bq: logging to Google BigQuery, great for production
• gsheets: logging to a Google Sheet, great for low-volume production

Backend Decorators

• async: a decorator to make logging asynchronous
• row: a decorator to make logging to row based backends easier

Installation

go install github.com/trichner/elog

Usage

package main

import (
	"github.com/trichner/elog"
	"github.com/trichner/elog/csv"
	"os"
	"time"
)

func main() {

	// create a new logger with the CSV backend
	logger, err := csv.NewCsvEventLogger(os.Stdout)
	if err != nil {
		panic(err)
	}

	// create a new event
	event := elog.NewEventBuilder().
		WithKind("user_login").
		WithTimeStamp(time.Now()).
		WithPayload(map[string]string{
			"user":   "Alice",
			"remote": "42.0.4.23",
		}).
		Build()

	// ... and log it!
	logger.Log(event)
}
