webpack-log

A common logging module for the Webpack ecosystem. webpack-log leverages loglevelnext.

Getting Started

First thing's first, install the module:

npm install webpack-log --save

Note: We do not recommend installing this module globally.

Requirements

webpack-log requires Node v6 or higher.

Usage

const weblog = require('webpack-log');
const log = weblog({ name: 'wds' }) // webpack-dev-server

log.info('Server Starting');

The code above will produce:

Options

The default export (function) will return a logger, given an options Object. The following is a property reference for the Object.

Note: the logger returned is unique by default, due to the nature of the webpack ecosystem. Please reference the unique option below for disabling this feature and to force caching.

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. Available levels and order are:

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

Note: The level names shown above correspond to the available logging methods, with the notable exception of the silent level.

name

Required
Type: String
Default: '<unknown>'

Specifies the name of the log to create. This property is required, and used to differentiate between loggers when webpack-log is used in multiple projects executing in the same process space.

timestamp

Type: Boolean
Default: false

If true, instructs the logger to display a timestamp for log output, preceding all other data.

unique

Type: Boolean
Default: true

If false, instructs the logger to used 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 space, loggers are created as unique instances by default. By passing false for this property, the module is instructed to cache the requested logger.
