Openfin React Hooks : useOpenFin()

A collection of React Hooks built on top of the Openfin API.

Installing the Demo

In order to install the Openfin React Hooks demo application, download the installer here and run the executable. If you haven't already installed an OpenFin application, this will install the required runtime. It'll also add the shortcut to Openfin React Hooks Demo to your desktop and start menu.

The project is deployed and hosted by AWS, so with each time the application is ran the latest released version will be used. This means no further installations will be needed to keep the installed project up to date.

Getting Started

1. npm install --save openfin-react-hooks
2. import {useDockWindow} from "openfin-react-hooks";
3. Enjoy!

Motive

Wrapping up the OpenFin API in a higher level hooks abstraction allows developers to share common functionality across React-based OpenFin applications.

Even the simpler hooks bridge across various versions of the OpenFin API, providing a consistent interface around OpenFin regardless of what environment the application resides within.

More complex hooks (e.g. useDockWindow) provide functionality that could save hours of development work if the same functionality was written from scratch.

Hooks

Currently, the collection of hooks consists of the following:

Name	Description
useBounds	Subscribe to the bounds of a window changing
useDocked	Detects if the current window is docked
useDockWindow	Dock a window to the edges of a screen
useFocus	Listen to and affect focus of a window
useInterApplicationBusSend	Auto-magically send properties on the InterApplicationBus whenever they change
useInterApplicationBusPublish	Auto-magically publish properties on the InterApplicationBus whenever they change
useInterApplicationBusSubscribe	Subscribe to a topic on the InterApplicationBus
useMaximized	Detects if the current window is maximized
useOptions	Listen to and update window options
useUserMovement	Listen to and update whether user movement is enabled / disabled for a window
useZoom	Listen to and update window zoom level
useChannels	Use the Channels API to send/receive messages between windows or applications

Example

The following example demonstrates the usage of the useInterApplicationBusSubscribe and useInterApplicationBusSend hooks in order to subscribe to the OpenFin InterApplicationBus and send a message:

import {useInterApplicationBusSend, useInterApplicationBusSubscribe} from "openfin-react-hooks";

const IDENTITY = window.fin.Window.me;
const TOPIC = "demo-topic";

const Component = () => {
    const [name, setName] = useState("John Smith");
    const { data } = useInterApplicationBusSubscribe(IDENTITY, TOPIC);
    useInterApplicationBusSend(IDENTITY, TOPIC, name);
    return (
        <div>
            <input type="text" onChange={(e) => setName(e.target.value)} value={name} />
            <div><strong>Received Message:</strong> {data ? data.message : "None"}</div>
        </div>
    )
}

Usage examples for all of the hooks can be found in the interactive demo, as detailed below.

Demo

If you'd like a demo of the current collection of hooks, you can do so by:

• Cloning the repository (e.g. git clone https://github.com/ScottLogic/openfin-react-hooks.git)
• Checkout the repository in your command line of choice (e.g. cd c:/dev/openfin-react-hooks)
• Run npm install and npm run compile within the root of the project directory
• Checkout the demo directory (e.g. cd demo)
• Run npm install and npm run start within the demo directory
• Once that's finished, execute npm run launch to see the demo application in all its glory
