I was wondering if there is a way to log the current filename or directory in React Native. Similar to how NodeJS does it with __filename and __dirname.

Note that as of React Native 0.29 and later, you can get logs without running the debugger. Just run react-native log-ios or react-native log-android on the command line inside your project folder. And when you open the Remote JS Debugging, you have to press option+command+i and check the console.
The most convenient way : Use react-native-document-picker, on selection it will give you a Relative path, something like this content://com.android...... . Pass that Relative path to Stat(filepath) function of the react-native-fetch-blob library. The object will return absolute path.
No, it's not possible since all the source code gets bundled together into one big file, and then a source map is provided so that you can debug it in the original structure.
You can see that by calling this code snippet somewhere in your code:
console.log(new Error().stack);
In a regular javascript you would get the entire trace with files and line numbers, but in react-native you get somthing like:
Error

which shows you the real files are gone.
