Webpack - 如何判断不为特定入口点编译 js 文件

Webpack - how to tell not compiling a js file for a specific entry point

上下文

我实际上是通过 npm 管理一些依赖项。然后我写了一个 webpack.config.js 来处理我的导入:

  1. 捆绑包 Jquery + popper + Bootstrap.js
  2. 将 codemirror 与我的模块需求捆绑在一起(xml 自动完成等)
  3. ...
  4. 从 fontawesome 收集字体 node_module

我正在使用 django,所以有一个 collectstatic 命令可以帮助我将所有脚本、字体、样式等收集到我想要的文件夹中。一切正常:

我能够获取 node_module 的字体,并按预期将其传送到正确的文件夹。

问题

我是 webpack 世界的新手,我肯定没有按应有的方式使用它,但它正在工作。
但是,当我 运行 编译我的东西时,会在我的 fonts 文件夹中生成一个 额外文件 fontawesome.js,是否可以避免这个 意外行为.
我错过了什么?

只要我不导入这个文件就没什么大不了的,但我不想污染我的存储库。

编辑

我更新了我的 webpack 配置代码。
好吧,我发现 js 文件是从我的入口点中的 filename 生成的。但我不想要这个文件:)

fontawesome.js

以及生成文件的内容,如果对webpack高手有帮助的话:

(() => {
    "use strict";
    var t = {};
    t.g = function () {
        if ("object" == typeof globalThis) return globalThis;
        try {
            return this || new Function("return this")()
        } catch (t) {
            if ("object" == typeof window) return window
        }
    }(), (() => {
        var r;
        t.g.importScripts && (r = t.g.location + "");
        var e = t.g.document;
        if (!r && e && (e.currentScript && (r = e.currentScript.src), !r)) {
            var p = e.getElementsByTagName("script");
            p.length && (r = p[p.length - 1].src)
        }
        if (!r) throw new Error("Automatic publicPath is not supported in this browser");
        r = r.replace(/#.*$/, "").replace(/\?.*$/, "").replace(/\/[^\/]+$/, "/"), t.p = r + "../"
    })(), t.p, t.p, t.p, t.p, t.p, t.p, t.p, t.p, t.p, t.p, t.p, t.p
})();

不幸的是,这是 webpack 中的一个错误:https://github.com/webpack/webpack/issues/11671

与此同时,可以直接添加一个自定义的 webpack 插件来删除这些文件。这是我用来删除所有 JS 文件的方法(因为我使用 CSS 文件作为我的条目):

plugins: [
    {
      // Delete empty JS files; work around for https://github.com/webpack/webpack/issues/11671
      apply: (compiler) => {
        compiler.hooks.afterEmit.tap('DeleteJSFilesPlugin', (compilation) => {
          const iter = compilation.emittedAssets.entries();
          for (const [key] of iter) {
            if (key.match(/.*\.js$/)) {
              fs.unlinkSync(path.join(compilation.outputOptions.path, key));
            }
          }
        });
      }
    }
  ]
