Copy assets

Why?

As a library author you may want to distribute certain assets that are outside of the library compilation such as a CHANGELOG.md or SCSS mixins.

How?

You can copy these assets by using the assets option in ng-package.json.

{
  "$schema": "...",
  "assets": [
    "CHANGELOG.md",
    "docs/**/*.md",
    { "input": "src/styles", "glob": "**/*.scss", "output": "styles" }
  ],
  "lib": {
    ...
  }
}

Note that the advanced asset pattern, with a same syntax as Angular Builder's one, is used for SCSS files in the example above to allow a different output dir, so that we can put our styles under projects/my-lib/src/styles instead of projects/my-lib/styles.

Exporting Styles

When including additional assets like Sass mixins or pre-compiled CSS, you need to add these manually to the conditional "exports" in the package.json of the primary entry point.

ng-packagr will merge the manually-added "exports" with auto-generated ones, allowing for library authors to configure additional export sub-paths, or custom conditions.

Example package.json

{
  "name": "your-library",
  "version": "1.2.3",
  "exports": {
    ".": {
      "sass": "./_index.scss"
    },
    "./styles/dark-theme": {
      "sass": "./styles/_dark-theme.scss"
    },
    "./styles/light-theme": {
      "sass": "./styles/_light-theme.scss"
    }
  },
  "peerDependencies": {
    ...
  },
  "dependencies": {
    ...
  }
}
