:wave: Extensions functions marked with `@JsExport...

# javascript

[Nacho Ruiz Martin]

👋 Extensions functions marked with @JsExport are exported in this form:

export declare function functionName(_this_: ExtendedClass);

Am I right to assume that the correct way of invoking this from typescript is:

const class: ExtendedClass
...
functionName(class)

?

If so, I’m getting a runtime error:

TypeError: (0 , module__WEBPACK_IMPORTED_MODULE_2__.functionName is not a function

Thanks!

Yes, your assumption is right, so it seems like a bug

[Nacho Ruiz Martin]

Do you need an issue to be created in the tracker?

[Artem Kobzar]

Yes, please

[Edoardo Luppi]

Could you post the issue number here? Thanks!

[Nacho Ruiz Martin]

Sure, let me create a reproducer first. I’ll work on that this week.

[Nacho Ruiz Martin]

As I was actually expecting, I can’t reproduce it in a small project. I’ll keep investigating this.

As weird as it may sound, this seems to be some caching problem. Because the same code behaves correctly on another device.

I’m generating the npm package using the Gradle task and then installing it using yarn in my Next project, so maybe there’s some cache I’m missing around.

Sounds so weird ☹️

[Nacho Ruiz Martin]

Yeah don't worry, since this is something on my environment, I'll figure it out.
