Ninjagoat-projections

An easy way for the viewmodels 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 ninjagoat-projections

Add this code to the bootstrapper.ts file:

import {ProjectionsModule} from "ninjagoat-projections"

application.register(new ProjectionsModule());

Point to the notifications endpoint of a prettygoat instance in one your modules .

import {ISocketConfig} from "ninjagoat-projections";

container.bind<ISocketConfig>("ISocketConfig").toConstantValue({
    "endpoint": "your_prettygoat_instance"
});

Usage

The data of a given projection can be retrieved by using a specific service: ModelRetriever. This service returns an Observable of type ModelState, where ModelState is a tuple to carry model and phase of the data(loading, content ready or failed).

let modelRetriever = serviceLocator.get<IModelRetriever>("IModelRetriever");

//To access the data of a projection named List registered in a Users area
let source = modelRetriever.controllerFor({
    area: "Users",
    viewmodelId: "List"
}).model;
