Calling the ImageOptim macOS app from a Node.js script
New Course Coming Soon:
Get Really Good at Git
sharp is what I usually use to optimize images in my Node.js scripts.
But sometimes I like using the ImageOptim macOS application to optimize images with a GUI.
This time I had the need to start it from a Node.js script.
Here’s what I did.
First I imported the child_process
built-in Node module:
import * as child from 'node:child_process'
then I called it in this way to optimize all images in a specific folder:
const images_folder = './img'
child.exec(`open -a ImageOptim ${images_folder}`)
This starts the app, you see its UI, but it’s not a big deal.
And I should note that this only works if you have the app installed.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
