graphify-node

Graphify

Create an graph layout for ELK Graphs.

This package itself will not create images of the graphs. It will only add information about the sizes and positions of every node.

Usage

You can install graphify via npm:

npm install graphify-node

API

The API consists of one method layout that will create a layouted Klay JSON Graph.

const graphify = require('graphify-node')

// ...

function monospace (str, style) {
  return {width: str.length, height: str.split('\n').length}
}

graphify.layout(graph, monospace)
.then((layoutedGraph) => {
  console.log(JSON.stringify(layoutedGraph))
})

The layout function needs the graph and a method that specifies how to measure the size of a text element. The terminal package below uses the monospace implementation above, but if your environment supports fancy font features the size estimation for a label will be more complex.

Examples

The package terminal-graphs uses graphify to layout graphs for the terminal.

In the buggy project graphify is used to create layouts for SVGs and web interfaces.

The buggy implementation uses a PhantomJS based font measurement in the browser to accurately determine the dimensions of an text element.
