BaseKoa class with typescript decorators for routing based on koa and @koa/router

import Koa, { DefaultContext, DefaultState } from 'koa';
import { BaseRouter, routeGet } from '@backlib/koa';

//// EXAMPLE - BaseRouter for class/decorator style API
class Hello3 extends BaseRouter<DefaultState, DefaultContext>{
    #count = 0;

    @routeGet('hello3')
    async hello(ctx: DefaultContext) {
        this.#count++;
        ctx.body = {
            message: `Hello3 from server ${this.#count}`
        }
    }
}

async function main() {

    const app = new Koa();

    const hello3 = new Hello3('/api/');
    app.use(hello3.middleware());   
    
    app.listen(8080);    
}

// Now http://localhost:8080/api/hello3 will return {message: "Hello3 from server ..."}
  • Typed Build with typescript for typescript.
  • Modern Node.js 14 and above, compiled with native class fields and null coalescing native support.
  • Minimalist Not a framework, just some libs that can be assembled into an application infrastructure code.
  • PromiseAsync/Await centric Use Promise/async/await patterns for all async calls.
  • Web Async Web request utilities based on koajs over express as it is a modern rewrite of more or less the same API with backed in support for Promise/async/await (simplify many of the usecases)
