☎️ Caller - A set of iterchangeable function call strategies

☎️ Caller

---

👩‍🔬 Please be aware that this package is still experimental, changes to the interface and underlying implementation are likely, and future development or maintenance is not guaranteed.

---

This package provides different interchangeable function (Callable) call strategies to manage call execution. The different strategies can be used to switch from synchronous to asynchronous executions and back for optimal performance.

Example

import {
  AsynchronousCaller,
  ImmediateCaller,
  SynchronousCaller
} from "@orlandohohmeier/caller";

function print(msg)
  console.log(msg);
}

Promise.all([
  new AsynchronousCaller().call(null, print, "c"),
  new ImmediateCaller().call(null, print, "b"),
  new SynchronousCaller().call(null, print, "a")
]).then(() => print("done"));

Asynchronous Caller

This caller uses setTimeout (Tasks) to defer calls until the stack is empty. The asynchronous strategy is useful when the calls take potentially longer as it allows the browser to render updates in between.

Immediate Caller

The immediate caller uses Promise.resolve() (MicroTasks) to postpone calls until the current task is done but before the next task is running. The caller makes the respective calls async without the penalty of a new task.

Please note that as the calls are scheduled to run before the next task, the browser may not be able to render update between calls.

Synchronous Caller

This caller synchronously calls the provided Callable (e.g. function).
