Warning

This approach will likely produce innaccurate sourcemaps.

A better approach is to inline templates/styles directly in the TypeScript sources, which guarantees sourcemaps will be correctly produced by TypeScript.

Such a build step can be found at https://github.com/filipesilva/angular-quickstart-lib.

rollup-plugin-angular-inline

Angular templateUrl and styleUrls inliner for Rollup, based on the angular/material2 inlining script. Also removes module.id since it isn't needed afterwards.

Operates over transpiled JavaScript files so you need to provide include globs to ensure replacement is only happening on Angular Components.

Used after ngc, to inline templates/styles for UMD bundles but still have es2015 files for tree shaking.

Installation

npm install --save-dev rollup-plugin-angular-inline

Example

// package.json
"scripts": {
  "build": "ngc && rollup -c rollup-config.js",
}

// rollup-config.js
import angularInline from 'rollup-plugin-angular-inline';

export default {
  entry: './src/index.js',
  dest: './bundles/my-lib.umd.js',
  format: 'umd',
  moduleName: 'ng.my-lib',
  globals: {
    '@angular/core': 'ng.core'
  },
  plugins: [
    angularInline({ include: './src/**/*.component.js' })
  ]
}
