Getting started

You can install react-vnc-display via Yarn or npm:

# If using Yarn:
yarn add react-vnc-display

# If using npm:
npm install --save react-vnc-display

The component from react-vnc-display is VncDisplay. This module can be required via ES imports, CommonJS require, or UMD.

import { VncDisplay } from 'react-vnc-display';

// using require
const { VncDisplay } = require('react-vnc-display');


After importing the component, it can be rendered with the required url prop:

import React from 'react';
import { render } from 'react-dom';
import { VncDisplay } from 'react-vnc-display';

  <VncDisplay url="wss://some-remote-display:5991/path" />
), document.getElementById('root'));

By default the VncDisplay will start out with dimensions of 1280x720, but will be resized to the dimensions of the display once the connection has been established. You can pass noVNC callbacks as props to VncDisplay to customize this and additional behavior.


VncDisplay accepts a single required property of URL:

Property Type Required? Description
url String The URL for which to create a remote VNC connection. Should include the protocol, host, port, and path.

In addition, most of the properties available to noVNC can be provided and will be passed through to the noVNC instance. Here are a few useful props:

Property Type Required? Description
onClipboard func Execute a function when the VNC connection's clipboard updates.
onUpdateState func Execute a function when the state of the VNC connection changes.
shared bool Specify whether a VNC connection should disconnect other connections before connecting.
wsProtocols arrayOf(string) Specify a list of WebSocket protocols this connection should support.
