next.config.jsのコールバック地獄を回避する

More than 1 year has passed since last update.

例えば

プラグインが増えてしまう度にコールバック地獄を見たくないですよね。

next.config.js
const withA = require('a')
const withB = require('b')
const withC = require('c')
module.exports = withA(withB(withC({
  webpack(config, options) {
    return config
  }
})))

どんどん増えていきます…。
毎度プラグインが増える度にコールバックを書き直す必要があります。

解決策

reduceで解決します。

next.config.js
const plugins = [
  require('a'),
  require('b'),
  require('c')
]

const webpackConf = {
  webpack(config, options) {
    return config
  }
}

module.exports = plugins.reduce((prev, current) => current(prev), webpackConf)

結構スッキリしました。
あとは、プラグイン追加の度に、pluginsに追加していけばオッケーです。
module.exports以下は書き直す必要がありません。
