A full application that demonstrates how to configure log4js

log4js-example

A full express application that demonstrates how to configure log4js for the most common use-case.

To run:

npm install
npm start

Log config

Config file is in config/log4js.json. It defines three appenders that are children of the clustered appender. The clustered appender makes sure that only the master process writes to the log files, otherwise having multiple processes try to write at the same time will cause problems. Three log files are defined: log/app.log gets all the log messages and is configured to rotate when the file gets to 10Mb in size, keeping 3 backups of the file; log/errors.log uses the logLevelFilter to only get ERROR messages; log/access.log contains only the http request logs, using the connect-logger, and is configured to rotate every day.

How can I Generate app.log file daily - datewise

I need help for generate app.log file on daily bases.

I have added pattern in log4js.json file for "apps" that
"app": {
"type": "file",
"filename": "./storage/logs/app.log",
"maxLogSize": 10485760,
"pattern": "-yyyy-MM-dd",
"numBackups": 3
},
but I'm getting error. Please help me to generate app.log file dynamic date wise. like app-14-apr-2020.log

configuration file log4js.json does not contain a valid configuration

When using the sample configuration file config/log4js.json log4js is unable to load this configuration:

 "appenderList.forEach is not a function" (TypeError: appenderList.forEach is not a function
    at configureAppenders (node_modules\log4js\lib\log4js.js:248:18)
    at configureOnceOff (node_modules\log4js\lib\log4js.js:308:7)
    at Object.configure (node_modules\log4js\lib\log4js.js:371:3)

A valid configuration file looks more like this:

{
    "appenders": [
      {
        "type": "dateFile",
        "filename": "log/access.log",
        "pattern": "-yyyy-MM-dd",
        "category": "http"
      },
      {
        "type": "file",
        "filename": "log/app.log",
        "maxLogSize": 10485760,
        "numBackups": 3
      }
    ]
  }

log4js not working with cluster

Log4js is not working with cluster. how can I make it work with cluster ?

res.error not a function

It is a minor bug, but i think in the route/users.js file, in the broken route the function should be res.send and not res.error.

The config file is one directory above bin/www

In the configuration of www seems that config directory is in the same level (because of the ./) but it is actually one level above

Should not it be ../ ?

Regards

app.log is also including access logs
