webpack 1

webpack.config.js

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const ThemePlugin = require('@alifd/next-theme-webpack-plugin');

module.exports = {
  entry: {

  },
  output: {
    path: path.join(__dirname, 'build'),
    filename: '[name].js'
  },
  resolve: {
    extensions: ['', '.js', '.jsx']

    loaders: [{
      test: /\.jsx?$/,
      loader: 'babel',
      query: {
        presets: [
          'es2015',

    }, {

      loader: ExtractTextPlugin.extract('css!fast-sass!@alifd/next-theme-loader?theme=@alifd/theme-package')

Query

• theme(String): theme package(eg: @alifd/theme-1) which come from https://fusion.design
• base(String): package with all variables (eg: @alifd/next)
• modifyVars(String/Object): inject some variables, such as: $css-prefix or $icon-font-path, value may be the following two types
  • { '$css-prefix': '"my-"' }
  • path.join(__dirname, 'variable.scss'), it should be an absolute path

Note: if you want to set modifyVars to object under webpack1, you should write as below:

{
  test: /\.scss$/,
  loader: ExtractTextPlugin.extract(`css!sass!@alifd/next-theme-loader?${JSON.stringify({ theme: '@alifd/theme-package', modifyVars: { '$css-prefix': '"my-"', '$icon-font-path': '"//xxx.com"' } })}`)
}
