Constructor must be called with the new operator
When I am trying to add vis-network not in main component I am getting error: Constructor must be called with the new operator
<template>
<el-container >
<el-main>
<network ref="network" :nodes="nodes" :edges="edges" :options="options"> </network>
<button @click="get_data">GetData</button>
</el-main>
</el-container>
</template>
<script>
export default {
components: { Notification },
data () {
return {
nodes: [],
edges: [],
options: []
}
},
methods:
{
get_data()
{
axios.get(base_url + '/graph')
.then((response) => {
this.nodes = response.data.nodes;
this.edges = response.data.edges;
}).catch((error) => {
console.log(error);
});
}
},
}
</script>
index.js:
import vueVisNetwork from 'vis-network'
import locale from 'element-ui/lib/locale/lang/ru-RU'
window.axios = require('axios');
Vue.use(ElementUI, { locale })
Vue.use(Router)
Vue.component('network', vueVisNetwork.Network);
window.base_url = "http://127.0.0.1:8000"
new Vue({
el: '#app',
locale: 'ru',
render: h => h(App)
});
I tried:
Vue.component('network', new vueVisNetwork.Network);
But got error:
Uncaught TypeError: Cannot read property 'hasChildNodes' of undefined
Sorry i am away from PC. Could you look my vue template in my github. I use it as base. And if I right remember did not update it.
I tried add vis not as root element, as I described before.

import vueVisNetwork from 'vis-network'
hmm... why import of vueVisNetwork is from vis-network? It should be vue-vis-network
@bubnenkoff this solve this problem import { Network } from "vue-vis-network"; Vue.component("network", Network);
Do you sure that I can use it with Parcel? After import I am getting error:

To break all project enough to add one line:
import { Network } from "vue-vis-network";
Vue.component('network', new vueVisNetwork.Network);
This should be
import { Network } from "vue-vis-network";
Vue.component('network', Network);
I've updated the Readme in master
Do not work. I checked right now and got error:
