在开发环境中获得minifyed javascript（Webpack）

Question

我不想在开发环境中使用minifyed javascript。 下面我附上了我的webpack文件和package.json的一部分。 因此，我无法捕获代码中发生的错误。 我也遇到了错误 -

1] Webpack.config.js

let task = manager.get((url?.absoluteString)!, parameters: nil, progress: nil, success: {
        (dataTask, responseObj) in

        if let dict : NSDictionary = responseObj as? NSDictionary {

            //print("Response: \(dict)")
            AuditListParser().parseAudit(jsonData: dict)
        }
    }, failure: {
        (dataTask, error) in
        print(error.localizedDescription)
    })
task.resume()

2] Package.json

                module.exports = config;

}，

我相信您的问题在您的devconfig中，您正在将devtool设置为source-map，这适用于生产版本。您应该尝试将devtool设置为eval或其他用于开发的选项，请参阅here。

例如

var devConfig = {
    devtool: 'eval',
    entry: ['webpack-hot-middleware/client?reload=true'],
    plugins: [
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.HotModuleReplacementPlugin(),
        new webpack.NoErrorsPlugin(),
        new webpack.DefinePlugin({
            'process.env': { NODE_ENV: JSON.stringify('development')}
        })
     ],
