# log

[![Hackage version](https://img.shields.io/hackage/v/log-base.svg?label=Hackage)](https://hackage.haskell.org/package/log-base)

[![Build Status](https://github.com/scrive/log/workflows/Haskell-CI/badge.svg?branch=master)](https://github.com/scrive/log/actions?query=branch%3Amaster)

A set of libraries that provide a way to record structured log messages with

multiple backends.

Supported backends:

* Standard output via

  [`log-base`](https://hackage.haskell.org/package/log-base).

* Elasticsearch via

  [`log-elasticsearch`](https://hackage.haskell.org/package/log-elasticsearch).

* PostgreSQL via

  [`log-postgres`](https://hackage.haskell.org/package/log-postgres).

## Example

A sample usage for logging to both standard output and Elasticsearch:

```haskell

{-# LANGUAGE OverloadedStrings #-}

module Main where

import Log

import Log.Backend.ElasticSearch

import Log.Backend.StandardOutput

main :: IO ()

main = do

  let config = defaultElasticSearchConfig

        { esServer = "http://localhost:9200"

        , esIndex  = "logs"

        }

  withStdOutLogger $ \stdoutLogger -> do

    withElasticSearchLogger config $ \esLogger -> do

      runLogT "main" (stdoutLogger <> esLogger) defaultLogLevel $ do

        logInfo_ "Hi there"

```
