Mongolog for node

Log everything everywhere, monolog for javascript and node

Monolog for node is heavily inspired by monolog PHP library that was written by mparaiso mparaiso@online.fr and now rewritten again.

Installation

npm install @sh4dow/monolog

Handlers

• ConsoleLogHandler : log to console
• StreamHandler : log to a stream
• CouchDBHandler : log to CouchDB
• MongoDBHandler : log to MongoDB
• TestHandler : log to an array
• NullHandler : logging to /dev/null

Processors (work in progress)

• ExpressProcessor : get express request data
• WebProcessor : get server data

Formatters

• JSONFormatter : format log to JSON
• LineFormatter : format log to a string

Usage

Basic usage

    var {Logger, formatter, handler} = require('@sh4dow/monolog');

    // create log channel
    var log = new Logger('name')

    // make formatter
    var jsonFormat = new formatter.JSONFormatter();
    // create handler
    var consoleLog = new handler.ConsoleLogHandler(Logger.DEBUG);
    //set formatter for handler
    consoleLog.setFormatter(jsonFormat);
    // add handler to created channel
    log.addHandler(consoleLog);

    // save all logs to file
    log.pushHandler(new StreamHandler('/path/to/your.log',Logger.DEBUG));

    // add records to the log
    log.info('InFo');
    log.warning('Foo');
    log.error('Bar');
    log.debug('Baz');

CouchDB Logging

    
    const {Logger, handler} = require('@sh4dow/monolog');
    logger = new Logger("couchdb logger");
    logger.pushHandler(new handler.CouchDBHandler({
        host:"localhost",
        dbname:"logger"
    }));
    
    logger.info('Logging to couchdb');

MongoDB Logging ( with mongodb package)

    
    const {Logger, handler} = require('@sh4dow/monolog');
    const mongodb = require('mongodb').MongoClient.connect("localhost",function(err,db){
        logger = new Logger("channel name");
        logger.pushHandler(new handler.MongoDBHandler(db,"log_collection"));
        logger.info("log message");
    });

Missing express.js and webServer processors will be soon.
