Minimal TS Logging framework

> [Live-Example]() | GitHub-Home

Very simple but extendable logger in TypeScript.

For now there are only two loggers define: ConsoleLogger and NoOpLogger but it
should be easy to define your own logger

Install

# NPM
npm install @mmit/logging

# YARN
yarn add @mmit/logging

Usage

The "default LogLevel" is 'INFO'

The most simplest way to get the logger is:

``typescript
import { LoggerFactory } from '@mmit/logging';

const logger = LoggerFactory.getLogger('test.Logger');

// Will not be shown
logger.debug("Shows message only if debug-level is set!");

// Will not be shown
logger.info("Shows message only if info-level is set!");

// Shows the warning message
logger.warn("Shows message only if warn-level is set!");
`

If you need more control:

`typescript
import { LoggerFactory, LogLevel } from '@mmit/logging';

const logger = LoggerFactory.for('test.Logger')
.level(LogLevel.DEBUG)
.get();

// Will be shown
logger.debug("Shows message only if debug-level is set!");

// Will be shown
logger.info("Shows message only if info-level is set!");

// Will be shown
logger.warn("Shows message only if warn-level is set!");
`

If you want to specify your own Log-Channel:

`typescript
import { LoggerFactory, LogLevel, Channel } from '@mmit/logger';

class MyCoolLogChannel implements Channel {
...
}

const myChannel = new MyCoolLogChannel();

const logger = LoggerFactory.for('test.Logger')
.on(myChannel)
.level(LogLevel.DEBUG)
.get();

logger.debug("Shows message only if debug-level is set!");
`
