Because of non compatible dependencies, I have to downgrade from vue3 to vue2. I have created a force directed graph with D3 library. Everything worked find with vue3 using composition api. I am not familiar with vue 2 and adapting my graph to vue2 has not been working out for me. In vue3 it was very straitforward and ref() made it pretty easy to accomplish. As for vue2, I have tried making good use of lifecycle hooks such as computed and watch
Any help is more than welcome
Here is a minimalistic representation of my working component in vue3. This component creates the graph in a svg and then renders it in the template.
<template>
<div class="col" style="position: absolute; width:100%; height:100%" >
<div class="main-map-container" style="overflow: hidden; width: 100%;">
<div ref="graph" class="canvas">
</div>
</div>
</div>
</template>
<script >
import {onMounted, onBeforeMount, ref} from 'vue'
export default {
setup(){
const graph = ref()
const links = [{src:"Amazon",target:"Aurora"},{src:"Amazon",target:"Aurora"},{src:"Amazon",target:"Zoox"},{src:"Amazon",target:"Rivian"}]
const nodes = [{id:"Amazon"},{id:"Aurora"},{id:"Zoox"},{id:"Rivian"}]
onBeforeMount( async ()=>{
const svgobj = ForceGraph(nodes, links)
graph.value.appendChild(svgobj);
})
function ForceGraph(
nodes,
links
){
// The code for the graph has been removed since it is much too long
return Object.assign( svg.node() );
}
return { graph }
}
}
</script>
<style></style>
This is the vue2 component that i have emptied for this post
<template>
<div class="col" style="position: absolute; width:100%; height:100%" >
<div class="main-map-container" style="overflow: hidden; width: 100%;">
<div ref="graph" class="canvas">
</div>
</div>
</div>
</template>
<script>
export default {
setup(){
},
methods: {
},
watch: {
},
props: {
},
computed: {
},
created() {
},
mounted() {
},
updated(){
},
data() {
return {
}}
}
