Particles.js into Vue component

Question

I'm trying to adapt particles.js to a Vue.js component from the example below: https://codepen.io/MichaelVanDenBerg/pen/WpXGRm

However, when using the code below, I get the following error message in the console:

[Vue warn]: Error in mounted hook: "TypeError: this.particles is not a function"

How can I fix it in the code below?

Template:

</template>
    <div>
        <div id="particles-js"></div>
    </div>
</template>

Script:

<script>
import particles from 'particles.js'
export default {
    mounted() {
        this.initParticles()
    },
    methods: {
        initParticles () {
            particles("particles-js", {

CSS:

<style scoped>
#particles-js {
    position: absolute;
    width: 100%;
    height: 100%;
    background: #00356B;
}
</style>

Answer 1

The particles.js package does not export anything, but rather it sets window.particlesJS.

To use this package, simply import it in your script, and then invoke particlesJS():

import 'particles.js'
export default {
  // ...
  methods: {
    initParticles() {
      window.particlesJS('particles-js', {/* ... */})
    }
  }
}
