} = require("customize-cra");

module.exports = override(
    fixBabelImports("import", {
        libraryName: "antd-mobile", libraryDirectory: "es", style: 'css' // change importing css to less
    }),
    // addLessLoader({
    //   javascriptEnabled: true,
    //   modifyVars: { "@primary-color": "#1DA57A" }
    // })

);
