How to install:

npm i -S lambda-hand

How to use:

import { Handler } from 'lambda-hand';
const middleware1 = (event: any, context:any) => {};
const middleware2 = (event: any, context:any) => {};
const middleware3 = (event: any, context:any) => {};

export const AuthorizationHandler = Handler()
  .use(middleware1)
  .use(middleware2)
  .use(middleware3)
  // .use(() => {throw new Error()})
  .setResponseHandler((event, context) => console.log(event, context))
  .setErrorHandler((error) => console.log(error));

or just:

import { Handler } from 'lambda-hand';
const middleware1 = (event: any, context:any) => {};
const middleware2 = (event: any, context:any) => {};
const middleware3 = (event: any, context:any) => {};

export const AuthorizationHandler = Handler()
  .use(middleware1, middleware2, middleware3)
  .setResponseHandler((event, context) => console.log(event, context))
  .setErrorHandler((error) => console.log(error));

The handler will return a function with the type:

 (event: any, context: any) => Promise<any>

How to extend a Handler:

export const UserHandler = Handler().extends(AuthorizationHandler);
