Grunt、Webpack 和 DllPlugin

Question

我无法想象如何将DllPlugin/DllReferencePlugin 与 Webpack 结合使用，同时还使用 Grunt 进行构建。对于那些不了解的人，DllPlugin 创建一个单独的包，可以与其他包共享。它还创建一个清单文件（重要）来帮助链接。然后，DllReferencePlugin 在构建时被另一个包使用以获取先前制作的 DllPlugin 包。为此，它需要之前创建的清单文件。

在 Grunt 中，这需要在 grunt 运行之前创建清单文件，不是吗？这是一个简化的代码示例：

webpack.dll.js

// My Dll Bundles, which creates
// - ./bundles/my_dll.js
// - ./bundles/my_dll-manifest.json
module.exports = {

    entry: {
        my_dll : './dll.js'
    },
    // where to send final bundle
    output: {
        path: './bundles',
        filename: "[name].js"
    },
    // CREATES THE MANIFEST
    plugins: [
        new webpack.DllPlugin({
            path: "./bundles/[name]-manifest.json",
            name: "[name]_lib"
        })
    ]
};

webpack.app.js

// My Referencing Bundle, which includes
// - ./bundles/app.js
module.exports = {

    entry: {
        my_app : './app.js'
    },
    // where to send final bundle
    output: {
        path: './bundles',
        filename: "[name].js"
    },
    // SETS UP THE REFERENCE TO THE DLL
    plugins: [
        new webpack.DllReferencePlugin({
          context: '.',
          // IMPORTANT LINE, AND WHERE EVERYTHING SEEMS TO FAIL
          manifest: require('./bundles/my_dll-manifest.json')
        })
    ]
};

如果您查看第二部分，webpack.app.js，我已经评论了一切似乎都会失败的地方。为了使 DllReferencePlugin 工作，它需要来自 DllPlugin 的清单文件，但在 Grunt 工作流中，grunt 将在 grunt 自身初始化时加载这两个配置，导致 manifest: require('./bundles/my_dll-manifest.json') 行失败，因为之前构建的 grunt 步骤webpack.dll.js 尚未完成，表示清单尚不存在。

Answer 1

var path = require("path");
var util = require('util')
var webpack = require("webpack");

var MyDllReferencePlugin = function(options){
    webpack.DllReferencePlugin.call(this, options);
}

MyDllReferencePlugin.prototype.apply = function(compiler) {
    if (typeof this.options.manifest == 'string') {
        this.options.manifest = require(this.options.manifest);
    }

    webpack.DllReferencePlugin.prototype.apply.call(this, compiler);
};


// My Referencing Bundle, which includes
// - ./bundles/app.js
module.exports = {

    entry: {
        my_app : './app.js'
    },
    // where to send final bundle
    output: {
        path: './bundles',
        filename: "[name].js"
    },
    // SETS UP THE REFERENCE TO THE DLL
    plugins: [
        new MyDllReferencePlugin({
          context: '.',
          // IMPORTANT LINE, AND WHERE EVERYTHING SEEMS TO FAIL
          manifest: path.resolve('./bundles/my_dll-manifest.json')
        })
    ]
};
