miniserver

Installation

yarn add @renanhangai/miniservices

Getting started

First, define your base application class App.ts

import { AppBase } from "@renanhangai/miniservices";
const ServiceConstructorMap = {};
export class App extends AppBase<typeof ServiceConstructorMap> {
	protected serviceConstructorMap = ServiceConstructorMap;
}

Then, define your base service class Service.ts

import { ServiceBaseGeneric } from "@renanhangai/miniservices";

export class ServiceBase extends ServiceBaseGeneric<import("./App").App>;

Define your service Random.ts

import { ServiceBase } from "./Service";

export class RandomService extends ServiceBase {
	getRandom(): number {
		return 2;
	}
}

Define your service in your app file App.ts

import { AppBase } from "@renanhangai/miniservices";
import { RandomService } from "./Random";
const ServiceConstructorMap = {
	random: RandomService
};
class App extends AppBase<typeof ServiceConstructorMap> {}

Run your app index.ts

import { App } from "./App";

async function main() {
	const app = await App.runFromArgv(process.argv);
	console.log(app.services.random.getRandom());
}

main();
