source-maps-debugging

Source maps bridge the gap between your TypeScript source code and the compiled JavaScript that actually runs. They allow debuggers to show your original TypeScript code, set breakpoints in .ts files, and provide meaningful stack traces. Without source maps, you're debugging compiled JavaScript, which is frustrating and error-prone.

Proper source map configuration is essential for productive debugging of TypeScript applications.

Enable source maps in development for debugging. Consider separate source maps in production for error reporting while keeping bundle sizes small.

在浏览器中调试 TypeScript 时使用。设置构建工具时使用。当堆栈跟踪显示已编译的代码时使用。当断点不起作用时使用。部署到生产时使用。 来源：marius-townhouse/effective-typescript-skills。
