logd

A powerful modular logging facility for node.js

Core features:

• Completely modular: log messages are packed into JSON objects and can be sent anywhere
• Routing: log messages with different levels can be sent to different targets
• Log source: log messages are tagged with the file and line where it was created
• Configurable output: the output of messages can be limited to certain levels
• Namespaces: all messages are part of user defined namespace which can be used for filtering

Using Logd

In the main file of your application or library, import the module, define a namespace and set a transport for the log output.

import logd from 'logd';
import ConsoleTransport from 'logd-console-transport';


// if this isn't code loaded by another application
// you should define a transport that is used for output
logd.transport(new ConsoleTransport());


// define the module we're logging from
const log = logd.module('my-service');


// start logging
log.info('some information');


// you may pass as many arguments as you like 
// to the log methods
log.error('something went wrong', err, {some: 'data'});


// if you just want to output temporary logs to the console
// that are not sent to any transport you may pass
// directly data to the module by invoking it directly
log(err, {an: 'object'}, 'direct to console logging ftw ;)');
