Question 1

How to use gulp-newer with SASS or LESS compilation?

Accepted Answer

Pipe your .scss or .less files through newer to the CSS output directory, similar to the image example. Use the dest option for the output folder to only process changed source files.

Question 2

gulp-newer vs gulp-cached: which is better for my project?

Accepted Answer

gulp-newer is simpler and file-based, ideal for straightforward incremental builds. gulp-cached uses in-memory caching and might handle complex dependencies better, but requires more configuration.

Question 3

Does gulp-newer work with Gulp 4 tasks?

Accepted Answer

Yes, it's compatible with Gulp 4 as it uses the standard stream API. The README examples use older syntax, but you can adapt them to Gulp 4's task functions or series/parallel methods.

Question 4

How to handle file deletions with gulp-newer?

Accepted Answer

gulp-newer does not automatically clean up deleted destination files. You'll need a separate task, like using del or gulp-clean, to remove stale files from the output directory.

Question 5

Can I use gulp-newer for minifying JavaScript files?

Accepted Answer

Yes, pipe JS files through newer to a destination folder before minification plugins like gulp-uglify. Configure dest as the output directory to skip unchanged files.

Question 6

What's the difference between mtime and ctime in gulp-newer?

Accepted Answer

mtime checks file modification time for content changes, while ctime checks change time for attributes like permissions. Use ctime if file attributes affect your build, as noted in the API options.
