JS error /_addons/new_format_pack/web/editor.js:219 Uncaught (in promise) TypeError: Cannot read property '$$' of undefined

I'm running into an issue with building this addon and trying to run it with Anki 2.1.46 on Linux. I'm new to Svelte so I could be doing something wrong. I did npm install in the web directory, then went up one directory and did bin/compile.sh, then bin/zip.sh

    function init(component, options, instance2, create_fragment2, not_equal, props, append_styles, dirty = [-1]) {
      const parent_component = current_component;
      set_current_component(component);
      const $$ = component.$$ = {
        fragment: null,
        ctx: null,
        props,
        update: noop,
        not_equal,
        bound: blank_object(),
        on_mount: [],
        on_destroy: [],
        on_disconnect: [],
        before_update: [],
        after_update: [],
        context: new Map(parent_component ? parent_component.$$.context : options.context || []),
        callbacks: blank_object(),
        dirty,
        skip_bound: false,
        root: options.target || parent_component.$$.root
      };

line 219 in this case is this:
root: options.target || parent_component.$$.root

"svelte": "3.39.0" in package.json fixes it.

Is this perhaps another example of problems with using Svelte across compilation units Henrik? I'm a bit worried this approach is not going to work for us if it's not a use case Svelte are trying to support.

@dae can you elaborate on what you're referring to ? I was a bit surprised to see that the example addon can be built without having access to anki's source code, I fully expected I would have to someone link to Anki's repository of Svelte components.

This specific issue was because I was using a newer Svelte version in this add-on, then Anki uses. I've downgraded the Svelte that the add-on uses to svelte@~3.38.2, and it works. This would mean that Svelte add-ons need to stay in sync with Ankis Svelte version (at least somewhat).

The issue with compilation units still exists though. However it's more about reactivity. I've been thinking about writing an esbuild extension, that can alleviate this, at least for now.
