推荐答案

tsconfig.json文件与TypeScript编译器(tsc)的配置相对应.

The tsconfig.json file corresponds to the configuration of the TypeScript compiler (tsc).

这些链接可以为您提供有关这些属性的详细信息:

以下是一些提示:

• 目标:用于编译输出的语言
• 模块:已编译输出中使用的模块管理器. system用于SystemJS，commonjs用于CommonJS.
• moduleResolution :用于解析模块声明文件(.d.ts文件)的策略.使用node方法，它们像模块(require('module-name'))一样从node_modules文件夹中加载
• sourceMap :生成或不生成源地图文件，以在浏览器中直接调试您的应用程序TypeScript文件，
• emitDecoratorMetadata :为源中的修饰声明发出或不发送设计类型的元数据，
• experimentalDecorators :是否为ES7装饰器提供实验性支持，
• removeComments :是否删除评论
• noImplicitAny :是否允许使用不带类型的变量/参数(隐式)

• target: the language used for the compiled output
• module: the module manager used in the compiled output. system is for SystemJS, commonjs for CommonJS.
• moduleResolution: the strategy used to resolve module declaration files (.d.ts files). With the node approach, they are loaded from the node_modules folder like a module (require('module-name'))
• sourceMap: generate or not source map files to debug directly your application TypeScript files in the browser,
• emitDecoratorMetadata: emit or not design-type metadata for decorated declarations in source,
• experimentalDecorators: enables or not experimental support for ES7 decorators,
• removeComments: remove comments or not
• noImplicitAny: allow or not the use of variables / parameters without types (implicit)
