cornerstone | asynchronous rendering of web pages

I'm trying to wrap my head around how to wire up a simple button in BigCommerce Stencil. I've been using this platform for about 24 hours now, so any help you can give is MUCH appreciated!! I haven't used Handlebars.js or jQuery in a few years so I'm pretty rusty.

I'm using the Cornerstone Theme.

What I'm looking to do is:

1. Click a button
2. Array of objects sent to my JS function
3. JS Function adds all the items in the array to the cart.

I feel like this shouldn't be that hard, but where I am getting stuck is.

1. Getting data that is available in the HTML to be available to my function.

I am trying to edit a BigCommerce theme using stencilLint. When I type the command:

Hello Friends I am facing very strange issue in flutter app!When test my app in debug mode its working fine while in release mode it shows the white screen actually this app is already publish in playstore after few days I change this app want to release second version when try build release apk its shows white screen while in debug mode working fine why it happen is it flutter version issue?please check below two screen shot? image one

I am trying to make a Dicom viewer app in react using Cornerstone.js library. I have two components in my react app. One is ImagePreview and the other is CornerStoneElement. CornerStoneElement is where I initialize the cornerstone library and it loads the current image in its state. When a new image is pushed to CornerStoneElement's state it is loading the new image in a weird way as all the aspect ratios are gone and the viewport is zoomed in. Upon switching the image multiple times through ImagePreview, the viewport keeps getting bigger and bigger. What I need is to reset the viewport whenever a new image is loaded in the CornerStoneElement component. Here is the code for both components.

I'm editing BigCommerce's cornerstone theme template with stenvil and want to view and make changes to the admin interface. Much like what's happening in this video tutorial https://www.youtube.com/watch?v=mdhSLKpTOBY&list=PLwTYtMwfzbe7EZiIWPAmPtuwRHkY7BG-0&index=9

But I'm not sure how to access the theme editor locally. I saw that the --theme-editor commands were removed from the stencil cli. It says that we should look at this documentation instead https://developer.bigcommerce.com/stencil-docs/configure-store-design-ui/store-design-overview but that doesn't show how the theme editor could be accessed from a local environment. Is this possible?

Is the only option to upload the theme and edit it from there? Has the ability to use a theme editor locally been removed?

Working from the Cornerstone theme in Stencil, I want to be able to do different things depending on whether I am on my local NPM environment or the production site.

Looking at the current URL is not enough as the page has to be already loaded for that. I want to have conditionals in the template, with handlebars, when the markup is being generated. Something like:

Apologies, I feel this is well worn territory, but I've looked hard and I'm still struggling with importing my python modules I have written. More specifically, I can only reference a module if I import directly. For compatibility with other packages, I need to use python-2.7.

For example, for package brcfiles.

File structure of brcfiles:

I'm writing the type definitions for a library I'm using. One function in the library identifies the mouse button clicked by an integer:
