#webpack chunkファイル名にbuildの度に現在時刻をいれる

Posted at

キャッシュされたものが利用されないようwebpackが生成するchunkファイル名にbuildの度に現在時刻をいれた時のメモ

webpack.config.jsoutput.chunkFilenameに現在時刻を含める

webpack.config.js
module.exports = {
    entry : {
        entry : "./entry.js",
    },
    output : {
        path: __dirname,
        filename: "bundle.js",
        chunkFilename: "[id].bundle.js?" + (+new Date),
        publicPath: "/js/"
    }
}
  • **(+new Date)**が現在時刻

HTMLに出力後は次のようになる

HTML
<script type="text/javascript" charset="utf-8" async="" src="/js/0.bundle.js?1444118019225"></script>
  • [hash]でも十分かもしれない。
    例えば、chunkFilename: "[id].bundle.js?[hash]",
  • QUERY_STRINGではなくファイル名とする方法も良いかもしれない。
    例えば、chunkFilename: "[id].[hash].js",
