Webpack：大小超过建议的限制 (244 KiB)

Question

这里是有问题的分支和回购：https://github.com/Futuratum/moon.holdings/tree/dev

您好，我遇到了这个问题，因为我有一个包含很多图像的资产文件夹。我不在乎大小，这对于现代网络用户来说应该是正常的。

如何忽略此错误？

我在这里找到了这个答案，但它没有帮助，因为我已经在实施 devtools 配置。

Webpack 4 "size exceeds the recommended limit (244 KiB)"

这是我的 webpack.config：

/* eslint-disable no-console */
import webpack from 'webpack';
import HtmlWebpackPlugin from 'html-webpack-plugin';
import ExtractTextPlugin from 'extract-text-webpack-plugin';
import CopyWebpackPlugin from 'copy-webpack-plugin';
import path from 'path';
import chalk from 'chalk';

const moonholdings = path.resolve(__dirname, 'moonholdings');
const app = path.resolve(__dirname, 'app');
const nodeModules = path.resolve(__dirname, 'node_modules');

const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
  template: path.join(__dirname, '/app/index.html'),
  inject: 'body'
});

const ExtractTextPluginConfig = new ExtractTextPlugin({
  filename: 'moonholdings.css',
  disable: false,
  allChunks: true
});

const CopyWebpackPluginConfigOptions = [{
  from: 'app/static',
  to: 'static/'
}];

const CopyWebpackPluginConfig = new CopyWebpackPlugin(CopyWebpackPluginConfigOptions);

const PATHS = {
  app,
  build: moonholdings
};

const LAUNCH_COMMAND = process.env.npm_lifecycle_event;

const isProduction = LAUNCH_COMMAND === 'production';
process.env.BABEL_ENV = LAUNCH_COMMAND;

const productionPlugin = new webpack.DefinePlugin({
  'process.env': {
    NODE_ENV: JSON.stringify('production')
  }
});

const base = {
  entry: ['babel-polyfill', PATHS.app],
  output: {
    path: PATHS.build,
    publicPath: '/',
    filename: 'index_bundle.js'
  },
  resolve: {
    modules: [app, nodeModules]
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.s?css/,
        use: [
          'style-loader',
          'css-loader',
          'sass-loader'
        ]
      },
      {
        test: /\.(png|jpg|jpeg|gif|svg|woff|woff2|ttf|eot)/,
        loader: 'file-loader?name=[path][name].[ext]'
      }
    ]
  }
};

const developmentConfig = {
  devtool: 'inline-source-map',
  devServer: {
    contentBase: moonholdings
  },
  plugins: [
    CopyWebpackPluginConfig,
    ExtractTextPluginConfig,
    HtmlWebpackPluginConfig
  ]
};

const productionConfig = {
  devtool: false,
  plugins: [
    CopyWebpackPluginConfig,
    ExtractTextPluginConfig,
    HtmlWebpackPluginConfig,
    productionPlugin
  ]
};

console.log(`${chalk.magenta('฿')} ${chalk.green('yarn run:')} ${chalk.red(LAUNCH_COMMAND)}`);

export default Object.assign(
  {}, base,
  isProduction === true ? productionConfig : developmentConfig
);

还有 package.json

Answer 1

产生警告的 webpack 4 功能称为Performance Hints。

默认情况下，如果条目包大小大于 250 KB (244 KiB)，webpack 会发出警告。

您可以自定义此限制，as explained in the documentation，将其添加到您的 webpack 配置中：

performance: {
  maxAssetSize: 1000000
}

这会将限制设置为 1 MB。

如果你想完全关闭 webpack 的性能提示，你可以这样做 (as explained in the documentation)：

performance: {
  hints: false
}
