Open Graph Plugin for Chat Engine

Identify if message.data.text contains an URL, send it to your server or a third party service and get the data collected into message.data.metadata which you can use in order to transform a plain message in a thumbnail.

Quick Start

npm install chat-engine-open-graph

1. Have a ChatEngine server running already, instantiate a client and connect it

const ChatEngine = ChatEngineCore.create({
    publishKey: 'pub-key-here',
    subscribeKey: 'sub-key-here'
});


ChatEngine.connect('Username');
ChatEngine.on('$ready', () = { ... });

2. Grab your API key from Opengraph.io . It should look a litte something like this:

const apiKey = "xxxxxxxxxxxxxxx";

3. Attach this plugin to the channel you want, in this case global

You have to inject a function to the attribute api which receive as a parameter the URL detected inside of message and arrange it into a query parameter to the API endpoint of the server side.

ChatEngine.global.plugin(ChatEngineCore.plugin['chat-engine-open-graph']({
  api: (url) => `https://opengraph.io/api/1.1/site/${encodeURI(url)}?app_id=${apiKey}`
}));

or

const opengraph = require('chat-engine-open-graph');

ChatEngine.global.plugin(opengraph({ api: (url) => `https://opengraph.io/api/1.1/site/${encodeURI(url)}?app_id=${apiKey}` }));
