Example

import { Hardware, GlobalHotkey } from "keysender";

const notepad = new Hardware(null, "Notepad"); // find Notepad handle by className and set it as workwindow

new GlobalHotkey({
  // register hotkey
  key: "f1",
  mode: "once",
  async action() {
    if (
      (notepad.workwindow.isOpen() || notepad.workwindow.refresh()) &&
      notepad.workwindow.isForeground()
    ) {
      notepad.workwindow.setView({ x: 0, y: 0 }); // move workwindow to top left corner of the screen

      const { width, height } = notepad.workwindow.getView();

      await notepad.mouse.humanMoveTo(width / 2, height / 2); // makes human similar mouse movement from current cursor position to middle of "Notepad" window

      await notepad.keyboard.printText("hello"); // instantly types "hello"

      await notepad.keyboard.sendKey("space", 50); // press key "space", await for 50 milliseconds, release key "space"

      await notepad.keyboard.sendKeys(["w", "o", "r", "l", "d"], [25, 50], 50);

      await notepad.keyboard.sendKey(["ctrl", "s"], 50); // press key combination "ctrl+s", await for 50 milliseconds, release key combination
    }
  },
});

Hardware or Virtual

/** Use entire desktop as workwindow */
constructor();
/** Use the first window with {handle} */
constructor(handle: number);
/**
 * Use the first window with {title} and/or {className} and sets it as current workwindow
 * */
constructor(title: string | null, className?: string | null);
/**
 * Use the first child window with {childClassName} and/or {childTitle}
 * of window with {parentHandle} and sets it as current workwindow
 * */
constructor(
  parentHandle: number,
  childClassName: string | null,
  childTitle?: string | null
);
/**
 * Use the first child window with {childClassName} and/or {childTitle}
 * of the first found window with {parentTitle} and/or {parentClassName}
 * and sets it as current workwindow
 * */
constructor(
  parentTitle: string | null,
  parentClassName: string | null,
  childClassName: string | null,
  childTitle?: string | null
);

Classes Hardware and Virtual provide the same keyboard, mouse and workwindow methods and have the same constructors, but:

• Class Hardware provides keyboard and mouse methods implementations on hardware level by inserts the events serially into the keyboard or mouse input stream. These events are not interspersed with other keyboard or mouse input events inserted either by the user (with the keyboard or mouse).

• Class Virtual provides keyboard and mouse methods implementations on virtual level by sending messages to workwindow, so it could work with background window.

  Note: Virtual keyboard and mouse methods do not work for all windows, for example, input line in certain window may accept message from printText method, but sendKey method makes no effect outside input line, or the window may accept a keystroke message from sendKey method but not accept mouse movement message from moveTo method.

import { Hardware, Virtual } from "keysender";

const foo = new Hardware("Some title");

await obj.mouse.humanMoveTo.cancelCurrent();

You can call cancelCurrent even if no method currently executing (it will have no effect and return resolved promise) or call it multiple times (each call will return the same promise as the first call)
