Question 1

How to set up gulp-notify to notify on build errors?

Accepted Answer

Use notify.onError() with gulp-plumber; for example, pipe your task through plumber with errorHandler set to notify.onError('Error: <%= error.message %>'). This triggers desktop alerts for errors without breaking the Gulp watch stream, as shown in the examples.

Question 2

gulp-notify vs just using console.log for build alerts?

Accepted Answer

gulp-notify provides OS-level desktop notifications that are more visible and reduce terminal clutter, ideal for monitoring tasks in real-time. Console.log is simpler and cross-platform but requires active terminal watching, making it better for scripts where notifications aren't critical.

Question 3

Can gulp-notify work on a server without a GUI?

Accepted Answer

Yes, but desktop notifications won't appear; you can disable it by setting the DISABLE_NOTIFIER environment variable to true, or use custom reporters to log messages instead. This is useful for CI/CD environments where GUI alerts are impractical.

Question 4

How to customize the notification message in gulp-notify?

Accepted Answer

Pass a string with Lodash templates (e.g., 'File: <%= file.relative %>') or a function that returns a message based on vinyl file data. The API section details options like message and title, allowing dynamic content from file properties or errors.

Question 5

Is gulp-notify compatible with Gulp 4?

Accepted Answer

Yes, gulp-notify works with Gulp 4 as it relies on standard vinyl streams, but check the npm version for updates. The README doesn't specify Gulp 4, but community usage indicates compatibility, though testing in your setup is recommended.

Question 6

How to make gulp-notify only notify at the end of a task?

Accepted Answer

Set the onLast option to true in the notify configuration; this ensures the notification triggers only after all files in the stream have been processed, preventing spam from multiple file events, as explained in the API section.
