# webpack-log

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

## Getting Started

First thing's first, install the module:

```console
npm install webpack-log --save
```

_Note: We do not recommend installing this module globally._

## Requirements

`webpack-log` requires Node v6 or higher.

## Usage

```js
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`](#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:

```js
[
  '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.
