broadcast

@gephi/gephi-lite-broadcast

The package @gephi/gephi-lite-broadcast is a browser TypeScript library to control a Gephi Lite instance using the Broadcast Channel API.

It exports a Driver class, that exposes various asynchronous methods to help feed Gephi Lite data, appearance settings, filters...

Here is a simple example to import a Graphology graph in Gephi Lite in a new tab:

import { GephiLiteDriver } from "@gephi/gephi-lite-broadcast";
import Graph from "graphology";

async function openGraphInGephiLite(graph: Graph) {
  const driver = new GephiLiteDriver();

  await new Promise<void>((resolve) => {
    // Wait for new instance to be fully working:
    driver.on("newInstance", () => {
      resolve();
    });
    driver.openGephiLite();
  });

  await driver.importGraph(graph.toJSON());

  driver.destroy();
}

TODO

1. Data update/reading:

• getGraph(): SerializedFullGraph / importGraph(graph: FullGraph)
• setGraphDataset / getGraphDataset / mergeGraphDataset
• setGraphAppearance / getGraphAppearance / mergeGraphAppearance
• setFilters / getFilters
• setSelection / getSelection

2. Other methods:

• ping (to check broadcast status)
• getVersion
• zoomToNodes / resetZoom
• computeMetric
• computeLayout / startLayout / stopLayout
• notify
• exportGraph
• methods to handle UI elements (right panel, left tabs, caption, fullscreen)

3. Events

• instanceCreation
• graphUpdate
• graphModelUpdate
• graphAppearanceUpdate
• filtersUpdate
• selectionUpdate
