Q&A
node、webpackのビギナーです。
GASをTypeScriptで書くために以下の記事を参考に環境を用意しました。
Google Apps Script をローカル環境で快適に開発するためのテンプレートを作りました - Qiita
ビルドやデプロイも問題なくできたため、実際にコードを書き始め、HTMLをパースする必要があったためcheerio-httpcliを使うことにしました。
Node.js用のスクレイピングモジュール「cheerio-httpcli」の紹介 - Qiita
以下のコマンドでcheerio-httpcliをインストールしました。
npm install --save-dev cheerio-httpcli
インストールは問題なく終わり、package.jsonのdevDependenciesにも"cheerio-httpcli": "^0.7.2",が追加されたことを確認しました。
./src/index.tsの1行目にvar client = require('cheerio-httpcli');と追記してnpm run buildを実行するとエラーがでました。

.\node_modules\cheerio-httpcli\libを確認したところcore.jsが存在していました。
調べるとこのjsをwebpackが読めていないためと分かったため、
webpack.config.jsonに
json
1 resolve: { 2 extensions: [".ts",".js"] 3 },
と追記してjsを読むようにしました。
再びnpm run buildを実行するとエラーがでました。

Critical dependency: the request of a dependency is an expressionや
Module not foundを解決する必要がありそうですが、調べてもわかりませんでした。
この後どうすればビルドできるようになるのでしょうか
環境
- Windows 7
- node v8.11.1
- npm 5.6.0

エラーの出ているchild_processやfsはNode.js組み込みのモジュールなので、ブラウザやGASなど、Node.js以外の環境では動きません。
当該のQiita記事のタイトルにもありますように、このcheerio-httpcliはNode.js環境で動かす専用です。
