Checkout Extensibility - limit character in address field in checkout

[paulmaliakel]

Hello!

I have a simple JS code in my checkout.liquid to set a character limit of 30 characters to address field in checkout. 

Is there a way I can do the same with new checkout extrensibility? 

Where can JS codes in the new checkout?

You might have to create a checkout UI app and add the code to checkout.js

There are basic instructions here that might get you in the right direction. I am working on a similar solution now so I might be able to post more instructions when I am done.
