bitwise-logger v0.0.4

bitwise-logger

Many years ago, in Java, I developed a preference for bitwise loggers, and hoped someone would eventually release one. That never happened and I adapted to the node highwatermark style of loggers.

Recently though I had a need for detailed, verbose logging that could be minimized, this called not only for more granular control (so you aren't dumping at a rate distorting timing), but also for segmentation of output.

It includes support for bitwise operations on the logger and the log event as well as channels and works in node and the browser.

Usage

The simplest thing to do is use the default static instance

import Logger from 'bitwise-logger';
//...
Logger.log('foo', Logger.DEBUG & Logger.INFO ) //log to either debug level

You can also configure and use your own instance

import { Logger } from 'bitwise-logger';
import consoleBridge from 'bitwise-logger/src/console.js';
//...
const logger = new Logger(); // create a new logger
logger.level = Logger.ERROR & Logger.INFO; //only log errors and info
logger.registerChannel(consoleBridge); // bind to the built-in console functions
logger.log('foo', Logger.DEBUG & Logger.INFO ) //log to either debug level

Testing

npm run test

to run the same test inside the browser:

npm run browser-test

to run the same test inside docker:

npm run container-test
