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.
