Question 1

How do I set up notify to watch a directory recursively in Go?

Accepted Answer

Use the Watch function with a path and event channel, and enable recursive watching via flags; the GoDoc provides code examples for configuring this with event filtering for specific changes.

Question 2

Notify vs fsnotify: which is better for file monitoring in Go?

Accepted Answer

Notify offers a more abstracted API with built-in recursive watching and cross-platform consistency, while fsnotify is simpler but may require manual handling for some features. Choose notify for robust multi-OS support and advanced filtering.

Question 3

Does notify work on Windows with network or virtual drives?

Accepted Answer

It relies on ReadDirectoryChangesW on Windows, which has limitations with remote paths; support varies by OS and filesystem, so test thoroughly for network drive scenarios.

Question 4

How can I filter only file write events with notify?

Accepted Answer

Set up your watcher to listen only to the notify.Write event constant, and use the event channel to handle those specific notifications, as detailed in the library's documentation.

Question 5

Is notify actively maintained and stable for production use?

Accepted Answer

Based on the README with build status badges and usage by projects like Syncthing, it appears well-maintained, but check GitHub for recent commits and issue activity to confirm.

Question 6

What are the performance costs of using notify on large directory trees?

Accepted Answer

While native APIs are efficient, monitoring thousands of files can incur overhead; benchmark with your use case and consider rate limiting or selective watching to optimize.
