Tarant DB Persist

Provide the capabilities to actors on the backend to be persisted using waterline adapters.

Installation

add it to your project using npm install tarant-db-persist --save or yarn add tarant-db-persist

Usage

Initialize the sync client with the waterline adapter from the persist storage you will be interested on

import { ActorSystem, ActorSystemConfigurationBuilder } from 'tarant';
import * as diskAdapter from 'sails-disk';
import { PersistResolverMaterializer } from 'tarant-db-persist';
import AppActor from '../AppActor';

const config = {
adapter: diskAdapter,
actorTypes: { AppActor }
};

const persister = await PersistMaterializer.create(config)

const system : any = ActorSystem.for(ActorSystemConfigurationBuilder.define()
.withMaterializers([persister])
.withResolvers([persister])
.done())

your actors will require to implement IUpdatable (UpdateFrom) and IExportable (toJson)

import { Actor } from "tarant";
import { IUpdatable, IExportable } from "tarant-db-persist"

export default class AppActor extends Actor implements IUpdatable, IExportable {

constructor(name: string) {
super(name)
}

addOne() {
this.counter++
}

toJson(){
return {
id: this.id,
type:"AppActor",
counter: this.counter
}
}

updateFrom({ counter }: any): void {
this.counter = counter
}

private counter = 1;
}
