Shopify Functions allow developers to customize the backend logic that powers parts of Shopify.
In this video we learn how to use Shopify Functions, what's new in 2023, and how we can use them to customize the Shopify Checkout. Further, we also cover how Shopify functions are different from Shopify scripts. As a new update, functions can now also be build by using Javascript. This is made possible through a new toolchain called Javy.

Awesome video. This was super helpful for me to develop 2 functions that our store desperately needed. You make the best Shopify tutorials available, even better than Shopify's own docs

Excellent video.
I wish that there existed a private discussion forum, that required a monthly payment, and that focuses on shopify. Not only s/w development, but also entrepreneurs, merchants, etc.. that have large success rates on all levels.
You could post serious questions, and *not* have people trying to market their consulting company, or their amazing shopify marketing skills, etc..
I'd pay for that.
To sum up, a place that requires money to join, and thus weeding out the time-wasting riffraff of the online world.

I would love to see you make videos about Shopify Bundles features. The docs seems confusing to me.

[BicycletteVolante]

Great to see some tuto videos, especially on apps which is one of the most interesting and challenging part of Shopify as a dev!

[srinathravichandran]

Hi Jan, how do we update our function and redeploy ? And how can we delete a function that we have already created? Please share your inputs...

[yashmakwana]

Hey Jan, I watch your videos regularly, which are very helpful. so thank you. :)

I found the video really helpful in understanding how Shopify Function works. It's awesome! Could you please make another video for me? I just need to know how to update the details in the checkout page Specifically, I want to hide the variant title, the recurring price info (like $40 every month) under the variant title, and the recurring subtotal.

Awesome video Jan - great explanations and super helpful to see your process while you code :) Thanks for sharing!!

[komal]

you are the best Shopify developer and also the best teacher

[rbt]

Don't think I'm at this level yet. Will re-visit once I get thru the Freemote course. Thanks!

[inhAnhTuan-jrrm]

Hey, thanks for the awesome video, bro! Any chance you could make a tutorial on Shopify bundles?

[robertpalmer]

Good Video - just a quick question: you mentioned pricing tiers and bundle packs are possible with the new features. Do you have examples of how to do this, it would be invaluable.

Thank you, Jan for the Excellent overview of Shopify functions, but I have a question I recently worked on functionality that uses cookies based data of product and it will adding to cart on the basis of cart value on checkout page this code will present in checkout.liquid file so now how i can implement this without checkout.liquid file.

Is there any way in Shopify functions?

[pixobe]

Thank you for the Video. Cart Transformstion API is listed as only for Shopify Plus Merchants. Does it mean if I use the function in my public app, then it will fail for non Plus merchants ?

[_akos]

Great Video Jan!

Do we have any information about when will be published to merchants the "Cart and Checkout Validation API"?

[jericmontana]

this is really helpful bro Jan! Lots of value. 😎Thanks! 🙏

[majovainilla]

Do you know if I have to run the Graph QL query on each store I install my app later on??

[maeishoj]

it does not allow me to use the development store, why? it just uses the default and i cant change it

[dakko]

Hi! Great video? Maybe you said in the video but when do developer preview features become accessible live?
