zlogger

The last console logger

Installation

install --save zlogger

Feature

• ?? Extends Console
• ?? Support custom prefix before every line
• ?? Support custom stdout and stderr
• ?? Support print time
• ?? Support child logger

Usage

zlogger is same as global console which has .log, .info, .warn, .error.

Every line will start with prefix that you customize.

t logger = new ConsoleLogger({
efix: '> ',

Specify stdout/stderr, default is process.stdout/process.stderr, you can use fs if you want to print to file.

t logger = new ConsoleLogger({
dout: fs.createWriteStream('stdout.log'),
derr: fs.createWriteStream('stderr.log'),

er.info('info');
er.error('error');

at stdout.log
at stderr.log

You can create a child logger, the first argument can be a ChildProcess or writable stream. If you give a prefix, it will print after prefix defined by the parent logger.

t cp = require('child_process');
t logger = new ConsoleLogger({
efix: 'prefix > ',

er.info('see directory')

t ls = cp.spawn('ls', { cwd: __dirname });
er.child(ls, '> ');

15:03:46] prefix > see directory
15:03:46] prefix > > History.md
15:03:46] prefix > > README.md
15:03:46] prefix > > index.js
15:03:46] prefix > > node_modules
15:03:46] prefix > > package.json
15:03:46] prefix > > test

.child will return a new logger.

t logger = new ConsoleLogger({
efix: 'parent> ',

er.info('parent');

t child = logger.child('child> ');
d.info('child');

15:02:43] parent> parent
15:02:43] parent> child> child

It will print time before prefix, format is [HH:MM:SS], but you can disable it.

??

• {WriteStream} stdout - stdout, .log and .info will pipe to it?default is process.stdout
• {WriteStream} stderr - stderr, .warn and .error will pipe to it?default is process.stderr
• {String|Function} prefix - every line will start with prefix, if it's a function, it will be called every line print.
• {Boolean} time - print time
