This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@rokucommunity/logger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Advanced Usage

Log inheritance and Prefixing

A Logger instance can inherit settings from a parent, only needing to provide settings for the values it wants to override. All loggers inherit from the base Logger that is the default export from this module.

Consider the following example:

const logger = require('./dist');
logger.log('Hello from logger');

const childLogger = logger.createLogger({prefix: '[Child]'});
childLogger.log('Hello from childLogger');

const grandchildLogger = childLogger.createLogger({prefix: '[Grandchild]'});
grandchildLogger.log('Hello from grandchildLogger');

Output:

[14:38:30.429][LOG] Hello from logger
[14:38:30.432][LOG] [Child] Hello from childLogger
[14:38:30.432][LOG] [Child][Grandchild] Hello from grandchildLogger
