Pretty print config

[vjpr]

Provide a print method which uses the prettyjson module to print YAML-like output of the webpack config.

Why?

• If you print a normal config object it will not show the names of the plugins, just their instance vars.
• prettyjson looks nicer and is easier to read.

I quite like this idea. I've never used the prettyjson module before but it looks promising. This has always been a problem in projects that required complex configuration. My hack solution would either involve stringifying or using node-inspector to see the raw output when resolving.

My only questions are:

• Does prettyjson handle regular expression objects? Previously, stringifying would simply return an empty object.
• Does prettyjson handle instance names (such as DefinePlugin)?
• How do you imagine this working? Would you expect another method (e.g. .print()) or something else?

Yep.

Does prettyjson handle instance names (such as DefinePlugin)?

Nope.

This method I wrote does:

function prettifyWebpackConfig(config) {
  const prettyConfig = _.clone(config, true)
  prettyConfig.plugins = config.plugins.map(p => {
    return {name: p.constructor.name, settings: p}
  })
  return require('prettyjson').render(prettyConfig)
}

How do you imagine this working? Would you expect another method (e.g. .print()) or something else?

.print() makes the most sense if we are printing with prettyjson. Maybe a class method too in order to not have to run resolve twice.

Also off-topic, maybe .toJSON() as an alias for resolve().
