Package description

What is webpack-log?

The webpack-log package is a logging utility used in the webpack ecosystem. It provides a way to output logs with different levels of severity, such as 'info', 'warn', and 'error'. It is designed to work with webpack's node.js API and plugins to provide a consistent logging experience.

What are webpack-log's main functionalities?

Creating a logger instance

This code sample demonstrates how to create a new logger instance with a specified name. The logger can then be used to output informational messages.

const log = require('webpack-log');
const logger = log({ name: 'wds' });
logger.info('Server is starting...');

Logging warnings

This code sample shows how to log a warning message using the logger instance created earlier.

logger.warn('This is a warning message.');

Logging errors

This code sample illustrates how to log an error message, which could be used to output error information during the build process or plugin execution.

logger.error('An error has occurred!');

Requirements

This module requires an LTS Node version (v8.0.0+).

Install

Using npm:

npm install webpack-log --save-dev

Usage

Create a new logger and use it to log something wild:

const getLogger = require('webpack-log');
const log = getLogger({ name: 'webpack-batman' });

log.info('Jingle Bells, Batman Smells');
log.warn('Robin laid an egg');
log.error('The Batmobile lost a wheel');
log.debug('And the Joker got away');

And there will appear magic in your console:

console magic

Options

level

Type: String
Default: info

Specifies the level the logger should use. A logger will not produce output for any log level beneath the specified level. Valid level names, and their order are:

[
  'trace',
  'debug',
  'info',
  'warn',
  'error',
  'silent'
]

For example, If a level was passed as { level: 'warn'} then only calls to warn and error will be displayed in the terminal.

name

Type: String
Default: <webpack-log>

Specifies the name of the logger to create. This value will be part of the log output prefix.

timestamp

Type: Boolean
Default: false

If true, the logger will display a timestamp for log output, preceding all other data

unique

Type: Boolean
Default: true

If false, the logger will use cached versions of a log with the same name. Due to the nature of the webpack ecosystem and multiple plugin/loader use in the same process, loggers are created as unique instances by default.
