log4js-faye-appender

log4js-faye-appender is a custom appender for log4js capable of publishing log to a faye server

Install

npm install log4js-faye-appender

Usage

Simply configure the appender with url and channel parameters:

log4js.configure({
    appenders: [
        {type: 'log4js-faye-appender', url: 'http://localhost:8000', channel: '/faye'},
        {type: 'console'}
    ]
});

When log4js fails to find a given appender in its own library, it attempts to find it in node_modules, which is why you do not need to explicitly require anything other than log4js. This implies that, in order to work properly, log4js-faye-appender itself must reside inside a node_modules directory.

Examples

The examples folder contains 4 elements:

• fayeServer which is a textbook faye server sample (in our case, the log aggregator)
• logger which is a sample code showing how to use log4js-faye-appender
• subscriber which is a simple node client to take a look at what the server pushes to its subscribers
• www a simple web log viewer

Note that while log4js-faye-appender as a module does not depend directly on log4js, logger.js does depend on log4js and so you must install it for it to run:

npm install log4js

Now, the simplest way to test this is to have 2 terminals and one browser:

• run node fayeServer.js
• open www/index.html inside your favorite browser
• run node logger.js
