在 Ionic 3 应用程序上放置 angular-cli.json 内容的位置

Where to put angular-cli.json content on Ionic 3 app

我将 videogular2Ionic 3 应用程序一起使用。你能告诉我如何使用 ionic 3 应用程序进行以下修改吗,因为它没有 angular-cli.json

我是这样安装的:npm install hls.js --save

angular-cli.json

{
        ...
        "apps": [
            {
                ...
                "scripts": [
                    "../node_modules/hls.js/dist/hls.min.js"
                ],
                ...
            }
        ],
        ...
    }

错误,因为我没有执行以上操作:

您需要按照以下步骤操作:

  1. 安装/复制JS文件到项目中,你可以使用npm或者 复制到特定文件夹。
    $ npm install videogular2 --save
    $ npm install @types/core-js --save-dev
    $ npm install hls.js --save
  1. 将此配置添加到您的 package.json
 ...
"config": {   "ionic_copy": "./config/copy.config.js" },
 ...
  1. 使用以下路径创建文件 ROOT_OF_YOUR_PROJECT/config/copy.config.js 并添加以下内容:
    module.exports = {
        copyAssets: {
            src: ['{{SRC}}/assets/**/*'],
            dest: '{{WWW}}/assets'
        },
        copyIndexContent: {
            src: ['{{SRC}}/index.html', '{{SRC}}/manifest.json', '{{SRC}}/service-worker.js'],
            dest: '{{WWW}}'
        },
        copyFonts: {
            src: ['{{ROOT}}/node_modules/ionicons/dist/fonts/**/*', '{{ROOT}}/node_modules/ionic-angular/fonts/**/*'],
            dest: '{{WWW}}/assets/fonts'
        },
        copyPolyfills: {
            src: ['{{ROOT}}/node_modules/ionic-angular/polyfills/polyfills.js'],
            dest: '{{BUILD}}'
        },
        copySwToolbox: {
            src: ['{{ROOT}}/node_modules/sw-toolbox/sw-toolbox.js'],
            dest: '{{BUILD}}'
        },
        copyVideogularStyles: {
            src: ['{{ROOT}}/node_modules/videogular2/fonts/videogular.css'],
            dest: '{{BUILD}}'
        },
        copyHlsScripts: {
            src: ['{{ROOT}}/node_modules/hls.js/dist/hls.min.js'],
            dest: '{{BUILD}}'
        },
    }


修改文件 src/index.html 以导入您的脚本和样式

<head>
...
    <link href="build/videogular.css" rel="stylesheet">
...
</head>

<body>

    <script type="text/javascript" src="build/hls.min.js"></script>

</body>

编辑:解释

我们在这里所做的是解决 Ionic 中的一个已知问题,即导入外部资产(脚本、样式、图像...)。

我们在 package.json 中添加了一个小的配置文件,它将强制 ionic 复制我们想要的 assets 在构建文件夹中。

构建文件夹是什么? build 文件夹是在应用程序运行时生成的文件夹。它包含您的 artifects。默认情况下,ionic 不包含此构建文件夹中的资产。

为什么我们要在 index.html 中添加 scripts & styles 标签?到目前为止,我们所做的很简单,只是将 assets 复制到 build 文件夹中。但是我们需要告诉应用程序使用它们。这就是为什么我们也在 index.html 中导入它们。注意我们在 index.html 中使用的路径,这是我们复制资产的路径。
