@icon-magic/logger

---

This package is responsible for exposing all the logging functionality for icon-magic. It contains a wrapper around winston.js for including the filename from where the logs are generated as a label in the logged message.

Logs are written to the following simulataneously:

1. console - logs of all levels
2. icon-magic-run.log - logs of all levels
3. icon-magic-error.log - only error logs

Usage

// Import the logger module and it's interface
import { Logger } from "@icon-magic/logger";

// Instantiate by passing the name of the file. This will be a label in the log message
const LOGGER: logger = new Logger("icon-magic:icon-models:asset");

// Log a debug message
LOGGER.debug("Icon generation has begun");

// Log an error message
LOGGER.error("Oh no! An error has occurred!");

This will print logs of the following format:

<timestamp> [<label>] <logLevel> <msg>

For example,

2019-05-15T17:40:40.056Z [icon-magic:icon-models:asset] debug: Asset test created in /Users/rchitloo/workspace/artdeco-icons-source_trunk/icons/shadows
