window is not defined Nuxt for vue-slick - vue.js

Question

Hello I am having an issue with Nuxts ssr. I a trying to add 'vue-slick' to my web app and no matter what I do it continues to show "window is not defined".
As you can see I have tried multiple ways to allow vue-slick to be loaded on client side. Using plugins didn't help, using process.client in my component did not work as well.
Components/Carousel/Carousel.vue
<template>
<div class="carousel">
<Slick ref="slick" :options="slickOptions">
<a href="http://placehold.it/320x120">
<img src="http://placehold.it/320x120" alt="">
</a>
...
<a href="http://placehold.it/420x220">
<img src="http://placehold.it/420x220" alt="">
</a>
</Slick>
</div>
</template>
<script>
if (process.client) {
require('vue-slick')
}
import Slick from 'vue-slick'
export default {
components: {
Slick
},
data() {
return {
slickOptions: {
slidesToShow: 4
},
isMounted: false
}
},
methods: {
}
}
</script>
nuxt.config.js
plugins: [
{ src: '~/plugins/vue-slick', ssr: false }
],
plugins/vue-slick
import Vue from 'vue'
import VueSlick from 'vue-slick'
Vue.use(VueSlick);
Thanks for any help you can give!

So this is due to nuxt trying to render the slick component on the server side, even though you have set ssr: false in nuxt.config.
I have had this issue in other nuxt plugins and these steps should fix it.
in nuxt.config.js add this to your build object:
build: {
extend(config, ctx) {
if (ctx.isServer) {
config.externals = [
nodeExternals({
whitelist: [/^vue-slick/]
})
]
}
}
}
and in the page where you are trying to serve it you have to not mount the component until the page is fully mounted. So in your Components/Carousel/Carousel.vue set it up like this:
<template>
<div class="carousel">
<component
:is="slickComp"
ref="slick"
:options="slickOptions"
>
<a href="http://placehold.it/320x120">
<img src="http://placehold.it/320x120" alt="">
</a>
...
<a href="http://placehold.it/420x220">
<img src="http://placehold.it/420x220" alt="">
</a>
</component>
</div>
</template>
Then in your script section import your component and declare it like this:
<script>
export default {
data: () => ({
'slickComp': '',
}),
components: {
Slick: () => import('vue-slick')
},
mounted: function () {
this.$nextTick(function () {
this.slickComp = 'Slick'
})
},
}
</script>
Bascially this means the component isn't declared until the mounted function is called which is after all the server side rendering. And that should do it. Good luck.

I found another simple solution.
simply install "vue-slick" package to your nuxt project.
$ yarn add vue-slick
then component markup like below.
<template>
<component :is="slick" :options="slickOptions">
<div>Test1</div>
<div>Test2</div>
<div>Test3</div>
</component>
</template>
Finally set data and computed properties like this.
data() {
return {
slickOptions: {
slidesToShow: 1,
slidesToScroll: 1,
infinite: true,
centerMode: true,
},
};
},
computed: {
slick() {
return () => {
if (process.client) {
return import("vue-slick");
}
};
},
},
This solution prevents slick component importing globally as a plugin in nuxt config.
