[英]NestJs project does not show the updates with "tsc" command before "npm run start" or "npm run start:dev"
我是 nestjs 的新手。 因此,出于学习目的,我开始了教程。 更新或更改代码后,我在结果中找不到任何反映。 请帮我解决一下这个。 我在这里提供我的tsconfig.json文件和package.json 。

我用“ nest new project_name
”命令创建了这个项目。 每次没有 tsc 命令似乎什么都做不了。 谢谢
NestJs 兼容打字稿和 JavaScript。 要将 nestJs 与 vanilla JavaScript(纯 javascript)一起使用,我们需要一个 babel 编译器。
因此,经过一些发现后,我设法找到了解决方案。 一开始我习惯于打开一个新模块,controller,并使用诸如“nest generate module user”,“nest generate controller user/user--flat”,“nest g service user”之类的命令进行服务。 我从 Udemy 的教程中学到了。 无论如何,现在我设法通过仅提供命令“nest g resource user”来解决这个问题。 它工作得很好。 虽然我不知道哪里出了问题。 谢谢
