Question

打开我的应用程序时，我一直收到React minification警告。

我将我的webpack，package.json和redux存储设置为我认为会禁用此警告的设置，但它仍然出现。

任何帮助将不胜感激。我正在从我的webpack，package.json和redux store复制代码。我在heroku上托管我的应用程序。

商店

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from '../reducers/root_reducer';

const middlewares = [thunk];

if (process.env.NODE_ENV !== 'production') {
  const logger = require('redux-logger');
  middlewares.push(logger.createLogger());
}

const configureStore = (preloadedState = {}) => (
  createStore(
    rootReducer,
    preloadedState,
    applyMiddleware(...middlewares)
  )
);

export default configureStore;

Webpack

var path = require('path');
var webpack = require("webpack");

var plugins = [];
var devPlugins = [];

var prodPlugins = [
  new webpack.DefinePlugin({
    'process.env': {
      'NODE_ENV': JSON.stringify('production')
    }
  }),
  new webpack.optimize.UglifyJsPlugin({
    compress: {
      warnings: true
    }
  })
];

plugins = plugins.concat(
  process.env.NODE_ENV === 'production' ? prodPlugins : devPlugins
)

module.exports = {
  entry: './frontend/gym_bump.jsx',
  output: {
    path: path.resolve(__dirname, 'app', 'assets', 'javascripts'),
    filename: './bundle.js',
  },
  module: {
    loaders: [
      {
        test: [/\.jsx?$/],
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'react']
        }
      }
    ]
  },
  devtool: 'source-map',
  resolve: {
    extensions: ['.js', '.jsx', '*']
  }
};

package.json

我解决了这个，愚蠢的错误。我在webpack中缺少插件：插件。

module.exports = {
  entry: './frontend/gym_bump.jsx',
  output: {
    path: path.resolve(__dirname, 'app', 'assets', 'javascripts'),
    filename: './bundle.js',
  },
  **plugins: plugins,**
  module: {
    loaders: [
      {
        test: [/\.jsx?$/],
        exclude: /(node_modules)/,
        loader: 'babel-loader',
        query: {
          presets: ['es2015', 'react']
        }
      }
    ]
  },
  devtool: 'source-map',
  resolve: {
    extensions: ['.js', '.jsx', '*']
  }
};
