ReactJS - 包括main.scss中的其他scss文件

时间:2017-09-03 20:18:28

标签: reactjs sass-loader webpack-loader

在我的reactJS应用程序中 - 我将所有.scss文件包含在一个main.scss文件中 - 在src文件夹中的styles文件夹下。我有以下webpack配置。尝试将main.scss文件直接包含在我的主要组件中 - 在' @ import'中收到错误我导入其他scss文件的位置。如果我包含单独的scss文件样式是好的 - 但如何使用一个main.scss文件以及如何包含它?

错误:意外的令牌,预期((1:8)

index.js

import React from 'react';
import { render } from 'react-dom';
import { createBrowserHistory } from 'history';
import { ConnectedRouter, routerMiddleware } from 'react-router-redux';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import App from './components/homepage';
import reducers from './reducers';
import '../styles/main.scss';


const history = createBrowserHistory();
const store = createStore(reducers, applyMiddleware(routerMiddleware(history)));

render(
  <Provider store={store}>
    <ConnectedRouter history={history}>
      <App />
    </ConnectedRouter>
  </Provider>
  , document.getElementById('app'));

if (process.env.NODE_ENV === 'development' && module.hot) {
  module.hot.accept();
  module.hot.accept('./reducers', () => {
    const nextRootReducer = require('./reducers').default; // eslint-disable-line global-require
    store.replaceReducer(nextRootReducer(store.asyncReducers));
  });
}

您应该在顶级React组件中通过javascript导入.scss文件。

import './styles/main.scss';

Webpack会将其包含在您的捆绑包中。

对于生产,您需要使用Extract Text Plugin作为webpack,它将从import语句中导出单独的css文件。

Webpack对.js个文件进行操作。您需要使用ExtractTextPlugin.scss转换为.css文件:

{test: /\.scss$/,
    use: ExtractTextPlugin.extract({
        fallback: "style-loader",
        use: [{
            loader: "css-loader" // translates CSS into CommonJS
        }, {
            loader: "sass-loader"
        }]
    })
}

将此webpack入口点设置为main.scss文件所在的目录,然后使用以下行在该目录中创建index.js

require("./main.scss")(或import ./main.scss

此处包含的路径:<link rel="stylesheet" type="text/css" href="./styles/main.scss">应该是生成的.css文件的路径。

以下设置适用于我。

webpack.config.js

{
    use: ExtractTextPlugin.extract({
      fallback: "style-loader",
      use: [
         'css-loader', //knows how to deal with css
         'autoprefixer-loader?browsers=last 3 versions',
         'sass-loader?outputStyle=expanded' //this one is applied first.
      ]
    }),
    test: /\.scss$/,
    exclude: /node_modules/
  }
顶部index.js

中的

import "./styles/main.scss";
import "./reactApp";

main.scss的例子

// Import any of your custom variables for bootstrap here first.
@import "my-theme/custom";
// Then, import bootstrap scss
@import "~bootstrap/scss/bootstrap";  
//for bootstrap 3 using bootstrap-sass
$icon-font-path: '~bootstrap-sass/assets/fonts/bootstrap/';
@import '~bootstrap-sass/assets/stylesheets/_bootstrap.scss';
// Finally import any custom styles.
@import "my-theme/master-theme";

我只是按照你的方式导入它们,不要重复使用id或类名,除非你希望样式是相同的:

import '../styles/main1.scss';
import '../styles/main2.scss';
....

喜欢那样等等
