observable-callback/dist/esm/observableCallback.js

A small utility for simplified creation of callback functions that publishes the argument to an observable stream when called.

import { Subject } from "rxjs";
var pass = function (input$) { return input$; };
export function observableCallback(operator) {
    if (operator === void 0) { operator = pass; }
    var subject = new Subject();
    return [subject.pipe(operator), function (arg) { return subject.next(arg); }];
}
