To use logging.js import it in javascript file and get default logger by calling getLogger method.

Logging class has static method setLogger which can be used to define new loggers.
Each logger has to have following static methods:
- debug,info
- ,notice
- ,warning
- ,error
- ,critical
- ,alert
- ,emergency
- .
Convention used in predefined loggers is to handle two parameters for each method:
- first for message which is string,context
- second for which is object.
`js
import Logging from '@sacoding/logging.js';
class FooLogger {
static emergency = () => {};
static alert = () => {};
static critical = () => {};
static error = () => {};
static warning = () => {};
static notice = () => {};
static info = () => {};
static debug = () => {};
}
Logging.setLogger('foo', FooLogger, false);
`
Third parameter of Logging::setLogger method is used to set new logger as default one if it is true.
To log with new logger call:
`js``
const fooLogger = Logging.getLogger('foo');
fooLogger.debug('bar');
