alasqlとwebpackの使い方は？

Question

私はwebpackでalasqlの使用に失敗しています。

npmjs pageに述べたように、私は私が私のwebpack.config.jsにこれを追加alasql

npm install --save alasql 

をinstalaled：

plugins: [ 
    new webpack.IgnorePlugin(/(^fs$|xlsx|xls|^path$)/), 

はその後、私のコードで私は

import alasql from 'alasql'; 

を行う。これは、にWebPACKの原因となりますこの巨大なエラーメッセージで失敗します：

webpack: bundle is now VALID. 

どのようにwebpackにalasqlを含めるべきですか？

Answer 1

チェックアウトhttps://github.com/agershun/alasql/issues/440詳細については、ignoreプラグインの正規表現を更新したようですが、json-loaderモジュールを使用してalasqlソースのjsonファイルを解析する必要があります。

TLDR; （WebPACKのコンフィグ）

... 
plugins: [ 
    ... 
    new IgnorePlugin(/(^fs$|cptable|jszip|xlsx|xls|^es6-promise$|^net$|^tls$|^forever-agent$|^tough-cookie$|cpexcel|^path$)/), 
    ... 
], 
... 
loaders: [ 
    ... 
    { 
     test: /\.json$/, 
     loader: 'json', 
     include: [__dirname, '/node_modules'] 
    }, 
    ... 
]
