[英]Optimizing webpack build time
保存文件中的更改后,我在编译项目时遇到问题; 文件的编译时间需要 2 分钟或更长时间。
为了解决这个问题,我采取了以下步骤:
1.在 babel-loader 中,属性 cacheDirectory 的选项对象中的文档设置为 true,cacheComprassion 为 false 2. 在 ts-loader 中,属性 transpileOnly 和 happyPackMode 属性的选项对象中的文档中设置为 true 3.dev-禁用工具以获得更好的性能 4. ForkTsCheckerWebpackPlugin 连接到打字稿中的检查类型 5. 代码拆分定制

请告诉我如何在保存文件后减少项目中文件的编译时间?
解决了这个问题。 问题出在 eslint-loader-webpack 插件中。 如果你安装了旧版本的 eslint-loader,那么一切正常。
