Browsers Support

Supports major browser versions released at 2020 or ES2020.

• Chrome: >=87
• Firefox: >=78
• Safari: >=14

Installation

You can install it from npm registry:

npm install ffxiv-overlay-api --save

Or import the library from CDNs:

Usage

After installation, you can import the library:

import { OverlayAPI } from 'ffxiv-overlay-api';
const overlay = new OverlayAPI();

// use static tool functions directly
OverlayAPI.isCEFSharp();
// import tool functions
import { isCEFSharp } from 'ffxiv-overlay-api';
isCEFSharp();

Then you can add bunch of different listeners.

overlay.addListener('CombatData', (data) => {
  console.log('listener of `CombatData`', data);
});
overlay.addListener('ChangeZone', (data) => {
  console.log('listener of `ChangeZone`', data);
});

Call this function once you’re done adding all of your listeners:

overlay.startEvent();

Once this function has been called, OverlayPlugin will start sending events. Some events will be raised immediately with current state information like ChangeZone or ChangePrimaryPlayer.

After that, put the URL of your overlay into OverlayPlugin, or use the WebSocket URL when enabled. Checkout the index.html for example usage, you can download this file and load it from the OverlayPlugin. Enable WebSocked in your plugin and add ?OVERLAY_WS=ws://127.0.0.1:[port]/ws or ?HOST_PORT=ws://127.0.0.1:[port] after you overlay URL to access the WebSocket server.

Checkout Development section for more details and my new overlay Skyline Overlay for example.
