@orbifold/vue-cytoscape v1.0.6

Vue Cytoscape Component

Install with npm install @orbifold/vue-cytoscape --save

and in a Vue application use something like this:

<script setup lang="ts">

import {ref, onMounted} from "vue";
const viewer = ref(null)

onMounted(() => {
  ( <any>viewer.value).addNode({id:"a", name:"Swa"})
})
</script>

<template>

<GraphViewer class="cytoscape" ref="viewer"/>

</template>

<style scoped>
  .cytoscape {
    height: 100vh;
    width: 100vw;
    position: absolute;
    top: 0;
    left: 0;
  }
</style>

In a Nuxt application create a plugin file with the following content:

import Cyto from "@orbifold/vue-cytoscape";
import { CytoUtils } from "@orbifold/vue-cytoscape";
export default defineNuxtPlugin((nuxtApp) => {
	nuxtApp.vueApp.use(Cyto);
	return {
		provide: {
			cyto: CytoUtils,
		},
	};
});

This will allow you to use the component and the utils in any page or code:

<template>
  <CytoscapeViewer class="cytoscape" ref="viewer"/>
</template>
<script setup lang="ts">
  import {onMounted, ref} from "vue";
  import {Graph} from "@orbifold/graphs";
  import {IGraphView} from "@orbifold/utils";

  const viewer = ref(null);
  const {$cyto} = useNuxtApp();
  onMounted(() => {
    const cy = <IGraphView>viewer.value;
    cy.addNode({id: "a", name: "Cytoscape"});
    cy.addNode({id: "b", name: "Vue"});
    cy.addEdge({sourceId: "a", targetId: "b", name: "is a part of"});
    cy.layout();
    cy.setStyle("schema")
  });
</script>
<style>
  .cytoscape {
    height: 100vh;
    width: 100vw;
    position: absolute;
    top: 0;
    left: 0;
  }
</style>

IGraphView

This Cytoscape wrapper implements the Qwiery IGraphView interface and it means you can transparently exchange it with other implementations. The yFiles and Linkurious Ogma implementations are more advanced but are not free.

Build and Testing

Clone the repo, install things (npm i). To build the library run npm run build and to test it run npm run test.

Sample Application

You can run the sample application with npm run dev and then open http://localhost:5173 (or whatever Vite shows in the console) in your browser.

If you include the Qwiery Graph package (npm i @orbifold/graphs) you can use diverse graph generators to create graphs and then visualize them with this component.

For instance

import { Graph } from "@orbifold/graphs";
const g = Graph.create("erdos");
const cy = <IGraphView>viewer.value; //see snippet above
cy.loadGraph(g);
cy.layout();

Graph structure

The loadGraph method expects a JSON graph:

const g = {
    nodes: [
      {id: 'a', name: 'A'},
      {id: 'b', name: 'B'}
    ],
    edges: [
      {sourceId: 'a', targetId: 'b', name: 'A to B'},

    ]
  };
  cy.loadGraph(g)

The name property is optional and will be used as the label of the node or edge. The style of the graph defines whether the label is shown or not.

There are many different graph structures out there and if you wish to convert or use them, see the Qwiery Graph package.
