Node.JS + TypeScript how I can track the source code from the stack trace?

Question

As I understand typescript will be transpiled to JavaScript and if something inside of my code will throw an error it will contain the stack trace with line numbers of JavaScript not TypeScript. Is any libraries, plugins exists to solve this problem for production running instance? I know that for web we have map.js files is something the similar exist for node.js?

Run your app using ts-node, not node directly.

If you're using nodejs >= v.12.0.0 add the --enable-source-maps flag (official doc) when executing node. If nodejs version is lower you can use this library or ts-node as mentioned above.
