【已解决】react-hot-boilerplate中把网络引用的css和js换成本地引用以便于提高加载速度

折腾了:

【未解决】把ReactJS-AdminLTE中的导航栏和标题栏集成到react-hot-boilerplate

之后,该去解决之前就需要解决的问题:

对于html中引用的各种css和js,都是之前网上找到的cdn的地址:

index.html

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>Sample App</title>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.15/js/dataTables.bootstrap.min.js"></script>
  </body>
</html>

尤其是:

https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.15/js/jquery.dataTables.min.js

https://cdnjs.cloudflare.com/ajax/libs/datatables/1.10.15/js/dataTables.bootstrap.min.js

之类的地址,由于是国外的地址,所以加载速度有时候很慢:

所以需要去换成本地加载。

就像之前的ReactJS-AdminLTE中的一样:

代码改为:

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>Sample App</title>

</html>

对应文件,也通过npm run build,都拷贝到对应的输出的文件夹了:

结果npm run dev去通过webpack-dev-server调试,结果无法加载:

不过,如果是直接加载本地html,则是可以找到对应的css和js的(虽然个别有问题)

webpack-dev-server 无法加载css

webpack-dev-server  not load local css js

Serving static assets in webpack dev server – Stack Overflow

webpack dev server cannot serve files in `contentBase` directory · Issue #362 · webpack/webpack-dev-server

此处出错的原因,自己也带改知道:

webpack-dev-server是从内存中加载的文件的

目前的可能的解决方案是:

把html中引入的文件,都改为:

加上此处的前缀

http://localhost:4000/adminlte/

然后就可以了?

即使可以,也还是太麻烦啊。。。

此处是已经设置了:

  devServer: {
    // hot: true,
    contentBase: path.resolve(__dirname, ‘build’),
    publicPath: path.resolve(__dirname, ‘/adminlte/’),
    // publicPath: path.resolve(__dirname, ‘/devServerPublicPath/’),
    compress: true,
    // port: 3000,
    port: 4000,
    historyApiFallback: true
  },

webpack-dev-server static css js

找不到解决办法。

去搜:

webpack-dev-server

开发中 Server(DevServer)

去加上:

    proxy: {
      ‘*’ : `http://localhost:${wdsListenPort}` // <– Proxy everthing!
    }

试试效果。

结果会导致:

[HPM] Error occurred while trying to proxy request /adminlte/ from localhost:4000 to http://localhost:4000 (ENOTFOUND) (https://nodejs.org/api/errors.html#errors_common_system_errors)

Error occured while trying to proxy to: localhost:4000/adminlte/

GET http://localhost:4000/adminlte/ 504 (Gateway Timeout)

实在没办法了,暂时只能是去修改html了

结果都改为:

<link rel="stylesheet" href="http://localhost:4000/adminlte/assets/lib/bootstrap/bootstrap.min.css”>
<link rel="stylesheet" href="http://localhost:4000/adminlte/assets/css/font-awesome/font-awesome.min.css”>
。。。

还是出错:

经过一番研究,发现去改为:

    <link rel="stylesheet" href="http://localhost:4000/assets/lib/bootstrap/bootstrap.min.css">
    <link rel="stylesheet" href="http://localhost:4000/assets/css/font-awesome/font-awesome.min.css">
。。。

然后就可以正常加载了:

期间需要去解决:

【已解决】webpack-dev-server调试时加载fontawesome-webfont.woff失败

【总结】

想要把之前index.html中的:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

改为:

<link rel="stylesheet" href="assets/lib/bootstrap/bootstrap.min.css">

但是npm run dev调用了webpack-dev-server,却无法正常加载。

最后是改为:

<link rel="stylesheet" href="http://localhost:4000/assets/lib/bootstrap/bootstrap.min.css">

才可以正常加载。

其中4000是此处的webpack-dev-server配置文件webpack.config.js中配置的devServer配置的端口port

  devServer: {
    // hot: true,
    contentBase: path.resolve(__dirname, ‘build’),
    publicPath: path.resolve(__dirname, ‘/adminlte/’),
    // publicPath: path.resolve(__dirname, ‘/devServerPublicPath/’),
    compress: true,
    port: wdsListenPort,
    historyApiFallback: true,
    open: true,
    openPage: ‘adminlte/’
  },

另外要注意的是:

此处的devServer的publicPath,此处为/adminlte/,是不需要的,此处的webpack-dev-server动态生成的内容,是在:

http://localhost:4000/

而不是加了publicPath的:

http://localhost:4000/adminlte/

另外,由于此处的index.html是自己编辑的静态的,所以导致:

此处都设置为了

http://localhost:4000/

导致如果直接打包发布到生产环境中后,就无法正常加载,还是要手动去改为:

<link rel="stylesheet" href="assets/lib/bootstrap/bootstrap.min.css">

才可以的。所以还是不方便,不能自动的根据是development还是production去是否加载前缀。

所以需要去:
