-# log4js-node
+# log4js-node [![Build Status](https://secure.travis-ci.org/nomiddlename/log4js-node.png?branch=master)](http://travis-ci.org/nomiddlename/log4js-node)
 
-This is a conversion of the [log4js](http://log4js.berlios.de/index.html) 
-framework to work with [node](http://nodejs.org). I've mainly stripped out the browser-specific code
-and tidied up some of the javascript. It includes a basic file logger, with log rolling based on file size, and also replaces node's console.log functions. 
 
-NOTE: in v0.2.x require('log4js') returned a function, and you needed to call that function in your code before you could use it. This was to make testing easier. v0.3.x make use of [felixge's sandbox-module](https://github.com/felixge/node-sandboxed-module), so we don't need to return a function.
+This is a conversion of the [log4js](http://log4js.berlios.de/index.html)
+framework to work with [node](http://nodejs.org). I've mainly stripped out the browser-specific code and tidied up some of the javascript. 
+
+Out of the box it supports the following features:
+
+* coloured console logging
+* replacement of node's console.log functions (optional)
+* file appender, with log rolling based on file size
+* SMTP appender
+* GELF appender
+* hook.io appender
+* multiprocess appender (useful when you've got worker processes)
+* a logger for connect/express servers
+* configurable log message layout/patterns
+* different log levels for different log categories (make some parts of your app log as DEBUG, others only ERRORS, etc.)
+
+NOTE: version 0.6.0 onwards will only work with node v0.10.x upwards, since it makes use of the new streams API. If you're using node 0.8 or lower, use log4js@0.5.7.
+
+NOTE: from log4js 0.5 onwards you'll need to explicitly enable replacement of node's console.log functions. Do this either by calling `log4js.replaceConsole()` or configuring with an object or json file like this:
+
+```javascript
+{
+  appenders: [
+    { type: "console" }
+  ],
+  replaceConsole: true
+}
+```
 
 ## installation
 
 npm install log4js
 
-## tests
-
-Tests now use [vows](http://vowsjs.org), run with `vows test/*.js`. 
 
 ## usage
 
 Minimalist version:
-
-           var log4js = require('log4js');
-           var logger = log4js.getLogger();
-           logger.debug("Some debug messages");
-
+```javascript
+var log4js = require('log4js');
+var logger = log4js.getLogger();
+logger.debug("Some debug messages");
+```
 By default, log4js outputs to stdout with the coloured layout (thanks to [masylum](http://github.com/masylum)), so for the above you would see:
+```bash
+[2010-01-17 11:43:37.987] [DEBUG] [default] - Some debug messages
+```
+See example.js for a full example, but here's a snippet (also in fromreadme.js):
+```javascript
+var log4js = require('log4js'); 
+//console log is loaded by default, so you won't normally need to do this
+//log4js.loadAppender('console');
+log4js.loadAppender('file');
+//log4js.addAppender(log4js.appenders.console());
+log4js.addAppender(log4js.appenders.file('logs/cheese.log'), 'cheese');
 
-    [2010-01-17 11:43:37.987] [DEBUG] [default] - Some debug messages
+var logger = log4js.getLogger('cheese');
+logger.setLevel('ERROR');
 
-See example.js:
-
-    var log4js = require('log4js'); //note the need to call the function
-    log4js.addAppender(log4js.consoleAppender());
-    log4js.addAppender(log4js.fileAppender('logs/cheese.log'), 'cheese');
-    
-    var logger = log4js.getLogger('cheese');
-    logger.setLevel('ERROR');
-    
-    logger.trace('Entering cheese testing');
-    logger.debug('Got cheese.');
-    logger.info('Cheese is Gouda.');  
-    logger.warn('Cheese is quite smelly.');
-    logger.error('Cheese is too ripe!');
-    logger.fatal('Cheese was breeding ground for listeria.');
-  
+logger.trace('Entering cheese testing');
+logger.debug('Got cheese.');
+logger.info('Cheese is Gouda.');
+logger.warn('Cheese is quite smelly.');
+logger.error('Cheese is too ripe!');
+logger.fatal('Cheese was breeding ground for listeria.');
+```
 Output:
+```bash
+[2010-01-17 11:43:37.987] [ERROR] cheese - Cheese is too ripe!
+[2010-01-17 11:43:37.990] [FATAL] cheese - Cheese was breeding ground for listeria.
+```    
+The first 5 lines of the code above could also be written as:
+```javascript
+var log4js = require('log4js');
+log4js.configure({
+  appenders: [
+    { type: 'console' },
+    { type: 'file', filename: 'logs/cheese.log', category: 'cheese' }
+  ]
+});
+```
 
-    [2010-01-17 11:43:37.987] [ERROR] cheese - Cheese is too ripe!
-    [2010-01-17 11:43:37.990] [FATAL] cheese - Cheese was breeding ground for listeria.
-
-  
 ## configuration
 
-You can either configure the appenders and log levels manually (as above), or provide a 
-configuration file (`log4js.configure('path/to/file.json')`) explicitly, or just let log4js look for a file called `log4js.json` (it looks in the current directory first, then the require paths, and finally looks for the default config included in the same directory as the `log4js.js` file). 
-An example file can be found in `test/log4js.json`. An example config file with log rolling is in `test/with-log-rolling.json`
-You can also pass an object to the configure function, which has the same properties as the json versions.
+You can configure the appenders and log levels manually (as above), or provide a
+configuration file (`log4js.configure('path/to/file.json')`), or a configuration object. The 
+configuration file location may also be specified via the environment variable 
+LOG4JS_CONFIG (`export LOG4JS_CONFIG=path/to/file.json`). 
+An example file can be found in `test/log4js.json`. An example config file with log rolling is in `test/with-log-rolling.json`.
+By default, the configuration file is checked for changes every 60 seconds, and if changed, reloaded. This allows changes to logging levels to occur without restarting the application.
 
-## connect/express logger
+To turn off configuration file change checking, configure with:
 
-A connect/express logger has been added to log4js, by [danbell](https://github.com/danbell). This allows connect/express servers to log using log4js. See example-connect-logger.js. 
+```javascript
+var log4js = require('log4js');
+log4js.configure('my_log4js_configuration.json', {});
+```
+To specify a different period:
 
-    var log4js = require('./lib/log4js');
-    log4js.addAppender(log4js.consoleAppender());
-    log4js.addAppender(log4js.fileAppender('cheese.log'), 'cheese');
-      
-    var logger = log4js.getLogger('cheese');
-    
-    logger.setLevel('INFO');
-    
-    var app = require('express').createServer();
-    app.configure(function() {
-        app.use(log4js.connectLogger(logger, { level: log4js.levels.INFO }));
-    });
-    app.get('/', function(req,res) {
-        res.send('hello world');
-    });
-    app.listen(5000);
+```javascript
+log4js.configure('file.json', { reloadSecs: 300 });
+```
+For FileAppender you can also pass the path to the log directory as an option where all your log files would be stored.
 
-The options object that is passed to log4js.connectLogger supports a format string the same as the connect/express logger. For example:
+```javascript
+log4js.configure('my_log4js_configuration.json', { cwd: '/absolute/path/to/log/dir' });
+```
+If you have already defined an absolute path for one of the FileAppenders in the configuration file, you could add a "absolute": true to the particular FileAppender to override the cwd option passed. Here is an example configuration file:
+```json
+#### my_log4js_configuration.json ####
+{
+  "appenders": [
+    {
+      "type": "file",
+      "filename": "relative/path/to/log_file.log",
+      "maxLogSize": 20480,
+      "backups": 3,
+      "category": "relative-logger"
+    },
+    {
+      "type": "file",
+      "absolute": true,
+      "filename": "/absolute/path/to/log_file.log",
+      "maxLogSize": 20480,
+      "backups": 10,
+      "category": "absolute-logger"          
+    }
+  ]
+}
+```    
+Documentation for most of the core appenders can be found on the [wiki](https://github.com/nomiddlename/log4js-node/wiki/Appenders), otherwise take a look at the tests and the examples.
 
-    app.configure(function() {
-        app.use(log4js.connectLogger(logger, { level: log4js.levels.INFO, format: ':method :url' }));
