Reflect is undefined on IE11 - Wrong vue-class-component version?

[ThomasPoncet]

The package can't be loaded on IE11 (it uses Reflect that I don't polyfill in my project):

'Reflect' is undefined

It seems that the package uses an old version of vue-class-components (v6.3.0) and this version breaks on IE11.

A fix has been released on the vue-class-components (v6.3.2).

If I manually clone the vue-slider-component GitHub repository, manually build the project and then replace in my project the directory node_modules/vue-slider-component by the directory where I cloned and build the vue-slider-component repository, I don't have the error on IE11 and vue-class-components is in version 6.3.2.

Is it possible to update vue-class-components on the published package? Or is the problem comming from my project?

Thank you for your help

I upgraded vue-class-component to 7.0.1 and re-released version 3.0.9.

@NightCatSama Thank your for your quick answer and action. I did try to update the package and it didn't fix the bug.

I did try something else: I did install vue-slider-component with npm in a new and clean directory

npm init
npm install -P vue-slider-component

And the version of vue-class-component in vue-slider-component seems still to be v6.3.0 (I open one of the js file in node_modules/dist, for example node_modulesdist/vue-slider-component.umd.min.js as it is the main, and I search Reflect).

I don't really understand how dependencies of vue-slider-component are packaged with vue-slider-component and then published on npm, but I feel like the wrong version of vue-class-component is sent to npm.

Let me know if I can add additional informations.

@ThomasPoncet Thank you for your help

In fact, the component does not directly use vue-class-component, I need to update is vue-property-decorator.

I released version 3.0.11, please help me test it again.

@NightCatSama Yes, it's fixed on my side! 🎉

Thank you very much for your help! 🙏

Have a nice day
