Grunt Imagemin on New Files

Question

I'm using Grunt Imagemin to optimize a folder of images. However everytime I run that command, it runs imagemin on ALL of the images. Is there a way to only run grunt imagemin when it detects new changes?

Answer 1

Try implementing grunt-newer :

Grunt Task for running tasks if source files are newer only .

Here you can find a short tutorial about how to use it.

After implementing it, you should prepend newer: to the imagemin task.
