# Vue Cytoscape Component



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



and in a Vue application use something like this:



```vue



import {ref, onMounted} from "vue";

const viewer = ref(null)



onMounted(() => {

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

})



  .cytoscape {

    height: 100vh;

    width: 100vw;

    position: absolute;

    top: 0;

    left: 0;

  }



```



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



```TypeScript

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:



```vue



  



  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")

  });



  .cytoscape {

    height: 100vh;

    width: 100vw;

    position: absolute;

    top: 0;

    left: 0;

  }



```



## IGraphView



This Cytoscape wrapper implements the [Qwiery](https://qwiery.com) `IGraphView` interface and it means you can transparently exchange it with other implementations.

The [yFiles](https://github.com/Qwiery/qwiery-vue-yfiles) and [Linkurious Ogma](https://github.com/Qwiery/qwiery-vue-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](https://github.com/Qwiery/qwiery-graphs) package (`npm i @orbifold/graphs`) you can use diverse graph generators to create graphs and then visualize them with this component.



For instance



```js

import { Graph } from "@orbifold/graphs";

const g = Graph.create("erdos");

const cy = viewer.value; //see snippet above

cy.loadGraph(g);

cy.layout();

```



# Graph structure



The `loadGraph` method expects a JSON graph:



```js



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](https://github.com/Qwiery/qwiery-graphs) package.
