无法判断Vue项目是否处于调试更多或Visual的发布模式

Question

我正在用Visual构建这个Vue应用程序，不管构建模式(调试/发布)如何，我仍然在控制台中得到以下消息。

您正在以开发模式运行Vue。为生产部署时，一定要打开生产模式。参见https://vuejs.org/guide/deployment.html上的更多提示

有没有办法知道我是真的处于发布模式，还是Vue只是在向我传递这条信息？

我知道这通常意味着JS文件被缩小了，Vue应用程序就是这样吗？

我不确定这是否有帮助，但这是我的packages.json文件

正如您发布的Vue.js部署指南所建议的，请检查您的webpack.config.js，并确保在部署应用程序时使用正确的mode the production环境。

在Webpack 4+中，您可以这样做：

module.exports = {
  mode: 'production'
}

但是在Webpack 3和更早版本中，您需要使用DefinePlugin

var webpack = require('webpack')

module.exports = {
  // ...
  plugins: [
    // ...
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('production')
    })
  ]
}

准备好后，只需运行npm run build即可开始捆绑模块。
