# Cytoscape.js Layers Plugin
[![License: MIT][mit-image]][mit-url] [![NPM Package][npm-image]][npm-url] [![Github Actions][github-actions-image]][github-actions-url] [![Cytoscape Plugin][cytoscape-image]][cytoscape-url]
A [Cytoscape.js](https://js.cytoscape.org) plugin for easy rendering of different layers in SVG, HTML, or Canvas format.
## Install
```sh
npm install cytoscape cytoscape-layers
```
## Usage
see [Samples](./samples) on Github
or at this [![Open in CodePen][codepen]](https://codepen.io/sgratzl/pen/XWXPMdM)
```js
import cytoscape from 'cytoscape';
import Layers from 'cytoscape-layers';
cytoscape.use(Layers);
const cy = cytoscape({
container: document.getElementById('app'),
elements: [
{ data: { id: 'a' } },
{ data: { id: 'b' } },
{
data: {
id: 'ab',
source: 'a',
target: 'b',
},
},
],
});
const layers = cy.layers();
layers.nodeLayer.insertAfter('html-static').node.innerHTML = 'Static Test Label';
layers.renderPerNode(layers.append('canvas'), (ctx, node, bb) => {
ctx.strokeStyle = 'red';
ctx.strokeRect(0, 0, bb.w, bb.h);
});
layers.renderPerNode(layers.append('html'), (elem, node) => {
elem.textContent = node.id();
});
layers.renderPerEdge(layers.append('canvas'), (ctx, edge, path) => {
ctx.strokeStyle = 'red';
ctx.stroke(path);
});
```
## Usage Examples
### Annotation
render a bar and a histogram below each node
Code: [annotation](./samples/annotations.ts)
### Edge Animations
using a animated linear gradient to animate edges in a separate layer
Code: [animatedEdges](./samples/animatedEdges.ts)
### Circular Context Menu
similar to Cytoscape Cxtmenu extension.
Code: [ctxmenu](./samples/ctxmenu.ts)
### HTML Label
similar to Cytoscape HTML Node Label extension
Code: [node-html-label](./samples/node-html-label.ts)
## Development Environment
```sh
npm i -g yarn
yarn set version latest
cat .yarnrc_patch.yml >> .yarnrc.yml
yarn
yarn pnpify --sdk vscode
