Chunks are not getting generated with @ngtools/webpack

[krischandra]

Versions

Angular CLI: 1.5.0
Node: 6.10.1
Angular 5
@ngtools/webpack version: 1.8.2

Webpack.common.js
module: {
rules: [{
loader: '@ngtools/webpack',
options: {
configFileName: 'tsconfig.webpack.json',
}
}],
plugins: [{
new AngularCompilerPlugin({
"sourceMap": true,
"tsConfigPath": helpers.root('tsconfig.webpack.json'),
"skipCodeGeneration": true,
"compilerOptions": {}
}),
}]
}
Actual result: Chunks is not getting generated for lazy loaded modules
Expected Result: Should generate chunks

pls post tsconfig.webpack.json
maybe there is problem

Do i need to use @angularclass/hmr-loader, ng-router-loader, angular2-template-loader while using
ngtools/webpack to generate chunks?. If so what should be the order do we need to follow?

Thanks in advance

tsconfig looks good.
Extra routing template loaders are no needed for new ngtools.

Maybe you have wrong defined routers.

Actually having the same problem here...

webpack:

var webpack = require("webpack");
var path = require("path");
var clone = require("js.clone");
var merge = require("webpack-merge");
var ExtractTextPlugin = require("extract-text-webpack-plugin");
var ContextReplacementPlugin = require("webpack/lib/ContextReplacementPlugin");
var TsConfigPathsPlugin = require("awesome-typescript-loader").TsConfigPathsPlugin;
var CheckerPlugin = require("awesome-typescript-loader").CheckerPlugin;
var DefinePlugin = require("webpack/lib/DefinePlugin");
var CopyWebpackPlugin = require("copy-webpack-plugin");
var isDevBuild = process.env.ASPNETCORE_ENVIRONMENT === "Production" ? false : true;
var isAotBuild = false;
var AngularCompilerPlugin = require('@ngtools/webpack').AngularCompilerPlugin;

module.exports = (env) => {

  if (env && env.prod)
    isDevBuild = false;

  if (env && env.aot) {
    isAotBuild = true;
  }
  var distDirectory = "./wwwroot/dist";
  var defaultLoaders = ["awesome-typescript-loader?silent=true", "angular2-template-loader", "angular-router-loader"];

  var sharedConfig = {
    resolve: {
      extensions: [".js", ".ts", ".css", ".scss", ".json"]
    },

    stats: { modules: false },
    context: __dirname,

    output: {
      filename: "[name].js",
      publicPath: "/dist/"
    },

    module: {
      loaders: [
        { test: /\.ts$/, use: isDevBuild ? defaultLoaders : isAotBuild ? '@ngtools/webpack' : defaultLoaders },
        { test: /\.html$/, use: "raw-loader" },
        { test: /\.css/, use: "raw-loader" },
        { test: /\.scss$/, use: ["raw-loader", "sass-loader"] },
        { test: /initial\.scss$/, use: ExtractTextPlugin.extract({ fallback: "style-loader", use: "css-loader!sass-loader?sourceMap" }) },
        { test: /\.json$/, use: "json-loader" },
        { test: /\.woff(2)?(\?v=.+)?$/, use: "url-loader?limit=10000&mimetype=application/font-woff&name=fonts/[name].[ext]" },
        { test: /\.(ttf|eot|svg)(\?v=.+)?$/, use: "file-loader?&name=fonts/[name].[ext]" },

        { test: /\.(png|jpg|gif)$/, use: "file-loader?limit=8192&name=assets/img/[name].[ext]" }
      ]
    },

    plugins: [ new CheckerPlugin() ]
  };

  var clientConfig = setTypeScriptAlias(require("./tsconfig.json"), {

    entry: {
      'main-client': "./Client/bootstrap-client.ts"
    },

    output: {
      path: path.join(__dirname, distDirectory),
      filename: "[name].js",
      publicPath: "/dist/"
    },

    plugins: [
      new DefinePlugin({ 'process.env': { 'development': true } }),
      new ContextReplacementPlugin(
        // The (\\|\/) piece accounts for path separators in *nix and Windows
        /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
        root("./Client")
      ),
      new TsConfigPathsPlugin({ tsconfig: "tsconfig.json" }),
      new webpack.DllReferencePlugin({
        context: __dirname,
        manifest: require("./wwwroot/dist/vendor-manifest.json")
      })

    ].concat(isDevBuild ?
      [
        new webpack.SourceMapDevToolPlugin({ filename: "[file].map", moduleFilenameTemplate: path.relative(distDirectory, "[resourcePath]") })
      ] :
      [
        new webpack.optimize.UglifyJsPlugin()
      ]
      ).concat(isAotBuild ?
        [
          new AngularCompilerPlugin({
            tsConfigPath: './tsconfig.json',
            entryModule: path.join(__dirname, 'Client/app/platform-modules/app.browser.module#AppBrowserModule'),
            exclude: ['./**/*.server.ts']
          })
        ] :
        [])
  });

  // Merge with Shared
  var mergedClientConfig = merge(sharedConfig, clientConfig);

  return [mergedClientConfig];
};

function setTypeScriptAlias(tsConfig, config) {
  var newConfig = clone(config);
  newConfig = newConfig || {};
  newConfig.resolve = newConfig.resolve || {};
  newConfig.resolve.alias = newConfig.resolve.alias || {};
  var tsPaths = tsConfig.compilerOptions.paths;
  for (var prop in tsPaths) {
    newConfig.resolve.alias[prop] = root(tsPaths[prop][0]);
  }
  return newConfig;
}

function root(args) {
  args = Array.prototype.slice.call(arguments, 0);
  return path.join.apply(path, [__dirname].concat(args));
}

scripts i use to compile:

    "build:dev": "webpack --config webpack.config.vendor.js --progress && webpack --config webpack.config.js --progress",

    "build:prod": "webpack --config webpack.config.vendor.js --progress --env.prod && webpack --config webpack.config.js --env.prod --progress",

    "build:prod:aot": "webpack --config webpack.config.vendor.js --progress --env.prod && webpack --config webpack.config.js --env.prod --env.aot --progress"

results for :dev are

results for :prod are:

results for prod:aot are...

As you can see it's not generating the chunks in AOT mode.
Strange thing is AOT compilation throws no error whatsoever...

[filipesilva]

There was a similar issue (#8597) where the problem was ContextReplacementPlugin. If that's not the problem in your case, could you set up a repro that I can clone to see the problem please?

[EmaGht]

Actually i was following the thread you linked aswell.
In my case, tho, the problem was this:

new webpack.DllReferencePlugin({ context: __dirname, manifest: require("./wwwroot/dist/vendor-manifest.json") })

I'm not really sure about what it does... i just took it from another template a couple months ago, but that was my deal-breaker.
Thanks for your interest!!

[filipesilva]

@EmaGht the @ngtools/webpack plugin is unfortunately not compatible with the DLLPlugin: #4565

[sjumble]

Hey @EmaGht have you resolved this issue, if Yes then can you please let us know the solutions.

[EmaGht]

@sjumble I just excluded the DllReference plugin from the plugin chain during aot build, you can see my webpack configuration in my rant about the current state of node's package manager here: yarnpkg/yarn#2088
