Chupacabras

An easy way for to access a prettygoat instance and it's projections. This module makes a connection via socket.io to receive realtime notifications from the projection engine and fetches automatically the new data.

Installation

$ npm install chupacabras

Construct the required services:

import {HttpClient, ModelRetriever, NotificationManager} from "chupacabras";
import * as io from "socket.io-client";

//Provide an instance of socket.io client, for example:
let socketClient = io.connect("your_endpoint");
let httpClient = new HttpClient();
let notificationManager = new NotificationManager(socketClient);
let modelRetriever = new ModelRetriever(httpClient, notificationManager);

Usage

The data of a given projection can be retrieved by using a specific service: ModelRetriever. This service returns an Observable with the projection state.

//To access the data of a projection named List registered in a Users area
let subscription = modelRetriever.modelFor({
    area: "Users",
    modelId: "List"
}).subscribe(data => {
   //Do something with data! 
});

To close the connection with a projection just dispose the subscription.
