让Webpack不要捆绑文件 [英] Get Webpack not to bundle files
问题描述
所以现在我正在使用一个原型，我们正在使用webpack（用于构建.tsx文件和复制.html文件）和webpack-dev-server之间的组合来进行开发服务。您可以假设我们也将React和ReactDOM用作几个库依赖项。我们当前的构建输出结构如下：
So right now I'm working with a prototype where we're using a combination between webpack (for building .tsx files and copying .html files) and webpack-dev-server for development serving. As you can assume we are also using React and ReactDOM as a couple of library dependencies as well. Our current build output is the following structure:
dist
-favicon.ico
-index.html
-main.js
-main.js.map // for source-mapping between tsx / js files
这会将所有模块（包括库依赖项放在大捆绑文件中）放置。我希望最终结果如下所示：
This places ALL of the modules (including library dependencies into on big bundled file). I want the end result to look like this:
dist
-favicon.ico
-index.html
-appName.js
-appName.min.js
-react.js
-react.min.js
-reactDOM.js
-reactDOM.min.js
我引用了index.html和import语句中的每个库在.tsx文件中。所以我的问题是这个...
如何从webpack生成这个巨大的捆绑.js文件到单独的.js文件（包括库，而不必单独指定每个）？ **奖励：我知道如何做prod / dev环境标志，所以我如何缩小这些单独的文件（再次没有捆绑它们）？
I have references to each of the libraries in index.html and in import statements in the .tsx files. So my question is this... How do I go from webpack producing this gigantic bundled .js file to individual .js files (libraries included, without having to specify each individually)? **Bonus: I know how to do prod/dev environment flags, so how do I just minify those individual files (again without bundling them)?
当前webpack.config ：
current webpack.config:
var webpack = require("webpack"); // Assigning node package of webpack dependency to var for later utilization
var path = require("path"); // // Assigning node package of path dependency to var for later utilization
module.exports = {
entry: [
"./wwwroot/app/appName.tsx", // Starting point of linking/compiling Typescript and dependencies, will need to add separate entry points in case of not deving SPA
"./wwwroot/index.html", // Starting point of including HTML and dependencies, will need to add separate entry points in case of not deving SPA
"./wwwroot/favicon.ico" // Input location for favicon
],
output: {
path: "./dist/", // Where we want to host files in local file directory structure
publicPath: "/", // Where we want files to appear in hosting (eventual resolution to: https://localhost:4444/)
filename: "appName.js" // What we want end compiled app JS file to be called
},
// Enable sourcemaps for debugging webpack's output.
devtool: "source-map",
devServer: {
contentBase: './dist', // Copy and serve files from dist folder
port: 4444, // Host on localhost port 4444
// https: true, // Enable self-signed https/ssl cert debugging
colors: true // Enable color-coding for debugging (VS Code does not currently emit colors, so none will be present there)
},
resolve: {
// Add '.ts' and '.tsx' as resolvable extensions.
extensions: [
"",
".ico",
".js",
".ts",
".tsx",
".web.js",
".webpack.js"
]
},
module: {
loaders: [
// This loader copies the index.html file & favicon.ico to the output directory.
{
test: /\.(html|ico)$/,
loader: 'file?name=[name].[ext]'
},
// All files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'.
{
test: /\.tsx?$/,
loaders: ["ts-loader"]
}
],
preLoaders: [
// All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
{
test: /\.js$/,
loader: "source-map-loader"
}
]
},
// When importing a module whose path matches one of the following, just
// assume a corresponding global variable exists and use that instead.
// This is important because it allows us to avoid bundling all of our
// dependencies, which allows browsers to cache those libraries between builds.
// externals: {
// "react": "React",
// "react-dom": "ReactDOM",
// "redux": "Redux"
// }
};
更新：
结束找到符合我需求的解决方案，尽管如此， webpack-y方式，需要一些额外的配置。仍然希望让它更具动感，但会在以后的时间点完善它。我正在寻找的解决方案是块常见模块的能力，但我将其称为文件名，在webpack中提供了入口点。我不介意将一些文件组合在一起，它有意义，但是由于项目不是SPA（单页应用程序），所以希望整个文件处于组件级别。
Update: Ended up finding a solution that fit my needs, although, again, in that webpack-y way, requires some additional configuration. Still would like to make it a little more dynamic, but will perfect this at a later point in time. The resolution I was looking for was the ability to "chunk" common modules, but I stated it as filename given "entry"-points provided in webpack. I didn't mind some files being combined, where it made sense, but wanted overall files to be at a component-level given the project wasn't a SPA (single page application).
附加代码最终成为：
plugins: [
new webpack.optimize.CommonsChunkPlugin({ // This plugin is for extracting and created "chunks" (extracted parts of the code that are common and aren't page specific)
// One of these instances of plugins needs to be specified for EACH chunk file output desired
filename: "common.js", // Filename for this particular set of chunks to be stored
name: "common", // Entry point name given for where to pull all of the chunks
minChunks: 3 // Minimum number of chunks to be created
})
]
我还必须通过变量名参数化入口点（参见下面的例子），以便我可以分配react，react-dom和redux mod使用common.js文件。
I also had to parameterize the entry points (see below for example), by variable name so that I could assign react, react-dom, and redux modules to common.js file.
entry: {
main: "./wwwroot/app/appName.tsx", // Starting point of linking/compiling Typescript and dependencies, will need to add separate entry points in case of not deving SPA
index: "./wwwroot/index.html", // Starting point of including HTML and dependencies, will need to add separate entry points in case of not deving SPA
favicon: "./wwwroot/favicon.ico", // Input location for favicon
common: [ "react", "react-dom", "redux" ] // All of the "chunks" to extract and place in common file for faster loading of common libraries between pages
},
推荐答案
将输出设置更改为名称驱动例如
entry: {
dash: 'app/dash.ts',
home: 'app/home.ts',
},
output: {
path: './public',
filename: 'build/[name].js',
sourceMapFilename: 'build/[name].js.map'
},
