我正在运行一个带有Postrges数据库连接的Express服务器,在理解编译器在处理Typescript时的工作方式方面,我算是个新手。
在设置之后,当我启动服务器时。我收到此错误
TypeError[ERR\u UNKNOWN\u FILE\u EXTENSION]:未知文件扩展名“.ts”
包裹。我的项目中的json文件如下所示

并将输出目录和根目录添加到您的tsconfig。json编译选项:
"outDir": "./build",
"rootDir": "./src",
您可以将nodemon配置为使用typescript。我推荐这个答案。
问题内容: 我正在学习swift,并制作了一个表格,其中包含显示图像的单元格,以及按MIME TYPE(使用路径扩展名)分组的类。我有一个关于扩展的问题。如果图像(例如,可能是视频或pdf)是从Internet上获取的,我不确定它们是否具有扩展名, 如何在不使用路径扩展名的情况下获取文件系统中文件的MIME类型? PS:很抱歉我的英语不好,这不是我的母语 问题答案: 假设您以NSData的形式接收
