Angular 6用资源构建图书馆 [英] Angular 6 building a library with assets

问题描述

在建设&打包Angular 6库后，我似乎无法指示Angular CLI将库的资源复制到每个版本的dist/assets文件夹中.

Upon building & packaging an Angular 6 library, I can't seem to be able to instruct the Angular CLI to copy the library's assets into the dist/assets folder on every build.

假设项目的文件夹结构是这个-

Assuming the project's folder structure is this -

- dist
- e2e
- node_modules
- projects
  - lib1
    - src
      - lib
      - assets
        - icons
- src

当我运行ng build lib1或ng build lib1 --prod时，assets/icons文件夹没有被复制到dist/lib1/assets/icons中.

When I run ng build lib1 or ng build lib1 --prod the assets/icons folder is not being copied into dist/lib1/assets/icons.

如果我运行ng build，则将复制src/assets(根src/assets)，但不会复制projects/lib1/assets.

If I run ng build then src/assets (the root src/assets) is being copied but not projects/lib1/assets.

angular.json文件包含对"assets": ["src/assets"]的引用，但不允许将assets键专门添加到项目中，而只能添加到主根应用程序中.添加时，出现以下错误:

The angular.json file contains a reference to "assets": ["src/assets"] but it won't allow adding the assets key specifically to the project, only to the main root app. When adding, I get the following error:

架构验证失败，出现以下错误:数据路径" 不应具有其他属性(资产).

Schema validation failed with the following errors: Data path "" should NOT have additional properties(assets).

我还尝试将以下自定义复制规则添加到资产，以将资产复制到dist/lib而不是dist/appname:

I also tried adding the following custom copy rule to the assets to copy the assets to dist/lib instead of to dist/appname:

  "assets": [
     "src/favicon.ico",
     "src/assets",
     { "glob": "**/*", "input": "src/assets/icons", "output": "../lib1/assets/icons" }
        ],

但是出现以下错误:

无法将资产写入输出路径之外的位置.

An asset cannot be written to a location outside of the output path.

是否有内置的方法来管理每个构建中的图书馆资产的副本?

Is there a built-in way of managing library asset's copy on every build?

我为此事向Angular CLI提出了一个问题，但尚未收到回音. 问题#11701

I opened an issue with Angular CLI regarding this but have not heard back yet. Issue #11701

推荐答案

当前，我仍然没有找到一种官方的内置方法.

Currently, I still have not found an official built-in way to do so.

我打开了 Angular CLI问题，希望能得到CLI团队的回应

I opened an Angular CLI issue and hopefully will get the CLI team response.

与此同时，我的解决方法是使用命令行工具:

In the meantime my workaround is using command line tools:

在package.json中我添加了:

"scripts": {
    ...
    "build": "ng build lib1 --prod && scss-bundle -c scss-bundle.config.json && cp -R projects/lib1/src/assets/ dist/lib1/assets/",
}

要复制SASS文件，我将scss-bundle与包含以下内容的配置文件scss-bundle.config.json一起使用:

To copy the SASS files I use scss-bundle with config file scss-bundle.config.json that contains:

{
  "entry": "./projects/lib1/src/assets/style/main.scss",
  "dest": "./dist/lib1/assets/style/styles.scss"
}

这会将项目的SASS文件构建为1个文件，并将其复制到dist文件夹中.我的SASS文件结构类似于:

This will build the SASS files of the project into 1 file and copy it into the dist folder. My SASS file structure is something like:

-- projects/lib1/src/assets/
                  -- style
                     -- main.scss
                     -- partials
                        -- _variables.scss
                        -- _styles.scss
                        __ _rtl.scss

因此，正如您所看到的，我不想运送所有原始的sass，而只运送一个最终文件.当然，您也可以将其编译为.css文件.

So as you can see I don't want to ship all the raw sass, just one final file. Of course, you can also compile it into a .css file instead.

为确保所有其他资产均被复制，我使用简单的Mac OS/Linux命令cp -R或rsync.

To make sure all other assets are copied, I use a simple Mac OS/Linux command cp -R or rsync.

当然，我运行的是npm run build，而不是运行ng build.

And, of course, instead of running ng build I run npm run build.

希望这会有所帮助，如果您有更好的解决方案，请告诉我.

Hope this helps, and if you have a better solution please let me know.
