Angular Compiler Webpack Plugin

Webpack 5.x plugin for the Angular Ahead-of-Time compiler. The plugin also supports Angular JIT mode.

Usage

In your webpack config, add the following plugin and loader.

import { AngularWebpackPlugin } from '@ngtools/webpack';

exports = { /* ... */
  module: {
    rules: [
      {
        test: /\.[jt]sx?$/,
        loader: '@ngtools/webpack'
      }
    ]
  },

  plugins: [
    new AngularWebpackPlugin({
      tsconfig: 'path/to/tsconfig.json',
    })
  ]
};

The loader works with webpack plugin to compile the application's TypeScript. It is important to include both, and to not include any other TypeScript loader.

Options

• tsconfig [default: tsconfig.json] - The path to the application's TypeScript Configuration file. In the tsconfig.json, you can pass options to the Angular Compiler with angularCompilerOptions. Relative paths will be resolved from the Webpack compilation's context.
• compilerOptions [default: none] - Overrides options in the application's TypeScript Configuration file (tsconfig.json).
• jitMode [default: false] - Enables JIT compilation and do not refactor the code to bootstrap. This replaces templateUrl: "string" with template: require("string") (and similar for styles) to allow for webpack to properly link the resources.
• directTemplateLoading [default: true] - Causes the plugin to load component templates (HTML) directly from the filesystem. This is more efficient if only using the raw-loader to load component templates. Do not enable this option if additional loaders are configured for component templates.
• fileReplacements [default: none] - Allows replacing TypeScript files with other TypeScript files in the build. This option acts on fully resolved file paths.
• inlineStyleMimeType [default: none] - When set to a valid MIME type, enables conversion of an Angular Component's inline styles into data URIs. This allows a Webpack 5 configuration rule to use the mimetype condition to process the inline styles. A valid MIME type is a string starting with text/ (Example for CSS: text/css).
