Is there a way to detect unused methods in a typescript file (Angular) in Visual Studio Code?有没有办法在 Visual Studio Code 的 typescript 文件（Angular）中检测未使用的方法？ I've tried a couple of plugins for Angular but in vain.我已经为 Angular 尝试了几个插件，但没有成功。 Web Storm used to grey out the unused methods by default. Web Storm 用于默认将未使用的方法灰显。 Looking for a similar thing in VS Code.在 VS Code 中寻找类似的东西。

Hi You can try to run your application with " ng serve --aot " cli command instead of " ng serve " , it shows you a whole number of these unused codes(like when you leave " ng build --prod " command).嗨，您可以尝试使用" ng serve --aot " cli 命令而不是" ng serve "来运行您的应用程序，它会向您显示所有这些未使用的代码（例如当您离开" ng build --prod "命令时）。

Or you can try this method but I'm not shure of this:或者你可以试试这个方法，但我不同意这个：

Hope it will work!希望它会奏效！

It is currently not possible to detect unused public methods in VSCode (you can check for updates here ).目前无法在 VSCode 中检测未使用的公共方法（您可以在此处检查更新）。 However, if it's a private method, you can mark it as private and VSCode is able to look for whether it is used or not within the scope (although do remember: methods used in the HTML template are public).但是，如果它是私有方法，您可以将其标记为私有，并且 VSCode 能够查找它是否在 scope 中使用（尽管请记住：在 HTML 模板中使用的方法是公共的）。

If the public method checks are important for you, you'll have to either wait, or contribute to the VSCode community.如果公共方法检查对您很重要，您将不得不等待，或者为 VSCode 社区做出贡献。 I still use VSCode but if it is a necessity for you, just switch to WebStorm for the moment.我仍然使用 VSCode，但如果您需要，请暂时切换到 WebStorm。
