If you were tasked with building a Go application to monitor and log changes in a directory, how would you approach this problem?
- Use the os.File package to watch for file system events and record changes in a log file.
- Poll the directory periodically to check for changes and log them when detected.
- Create a custom file system monitoring tool from scratch.
- Use a third-party library to handle file monitoring and logging.
To build a Go application for monitoring and logging changes in a directory, it's recommended to use the os.File package, specifically the fsnotify package, to watch for file system events. This approach is more efficient than polling the directory periodically, as it allows your application to react immediately to changes. Creating a custom tool from scratch can be time-consuming, and using a well-established third-party library is often a good practice to save development time and ensure reliability.
