Function Weenie

Framework function

Weenie is the function that kicks off the creation of a resource bag. It is intended to be used to build up and then seal a final resource bag to be passed around in an application in order to provide common dependencies.

Here's how it is intended to be used:

function init(): { firstDep: string };
function a(deps: { firstDep: string }): { a: number };
function b(deps: { firstDep: string; a: number }): { b: boolean };
function c(deps: { firstDep: string; a: number; b: boolean }): { c: string };
function d(deps: { firstDep: string; a: number; b: boolean; c: string }): {};
function e(deps: { firstDep: string; a: number; b: boolean; c: string }): { e: number };
function finish(
  deps: { firstDep: string; a: number; b: boolean; c: string, e: number }
): { a: number; b: boolean; c: string; }; // << these are the final exposed dependencies

const app = Weenie(init)
  .and(a)
  .and(b)
  .and(c)
  .and(d)
  .and(e)
  .done(finish);
Copy

The above initializes all the necessary dependencies and then seals them up, presenting a final "app" that is typed as { a: number; b: boolean; c: string }. This can then be passed along to web handlers, message handlers, cronjobs, etc., to perform the work that the service needs to do.
