envlogdriver

Zerolog based logging libary optimized for serverless application.

What is this package?

This package provides simple structured logger optimized for serverless application based on zerolog.

Key features of envlogdriver are:

• zerolog based simple method chaining API
• log level is set from environment variable

Usage

First of all, initialize a logger.

logger := zerodriver.NewLogger() // log level set from LOG_LEVEL environment variable. (if not exists then set to `debug`)

Then, write logs by using zerolog based fluent API!

logger.Info().Str("key", "value").Msg("Hello World!")
// output: {"severity":"INFO","key":"value","time":"2009-11-10T23:00:00Z","message":"hello world"}

Here's complete example:

package main

import (
    "github.com/ma91n/envlogdriver"
)

func main() {
    logger := envlogdriver.NewLogger()
    logger.Info().Str("key", "value").Msg("hello world")
}

// output: {"level":"INFO","key":"value","time":"2009-11-10T23:00:00Z","message":"hello world"}
