Installation

Use npm to install AHK NodeJS. If AutoHotKey.exe is not installed on your computer, please install it or refer to another npm module, ahk.exe.

npm i ahknodejs

Important Notes

When a parameter is followed by a question mark, it means it is optional
If curly brackets are to be used in strings, the must be escaped as such: "\\{"
Special characters in strings can be typed the same way as in AutoHotKey, as shown here
AHKNodeJS executes AHK commands in a set order asynchronously, so await is pretty much required as AHK commands attempting to run synchronously will likely crash the script.
When RGB hex strings are mentioned, it is talking about a color focused as RRGGBB without a 0x or # prefix

Initiation

const ahk = await require("ahknodejs")(Path, Hotkeys?, Options?);

Path - A string representing the location of AutoHotKey.exe

Hotkeys - A list of either strings and/or objects representing the hotkeys that will be used. The hotkeys will need to be set in order to be used.

If a string is used, it will be formatted the same way AutoHotKey hotkeys are formatted. This is further explained here.
If an object is used, it be in one of two forms depending on if multiple keys are used in the hotkey

Note: if noInterrupt is set to true, the keys will still be sent when the hotkey is triggered. This option defaults to false.

One Key:

{
  key: "KEY TO LISTEN",
  modifiers: [
    "list of modifiers"
  ],
  noInterrupt: true or false
}

Modifiers that can be used are win, alt, control, shift, and any (any modifier will trigger the hotkey). This defaults to an empty array if not provided.

Multiple Keys:

{
  keys: [
    "KEY TO LISTEN",
   ],
  noInterrupt: true or false
}

Note: If a multi-key hotkey is used, it will trigger no matter what modifers are present in accordance with AutoHotKey

Options:

An object with the options to set for AHKNodeJS. The properties are listed below:

defaultColorVariation - If the color variation is not set for imageSearch and pixelSearch, this number is automatically used. (Defaults to 1)

Returns - The AHK object

The AHK Object

The AHK object holds all the functions that are used to communicate with AutoHotKey as well as other properties that may be useful. Such properties and functions will be listed below.

Note: In the following bits of code, AHK is the AHK object.

Properties

Options - The AHK object contains the options that were used to initiate it as different properties of the AHK object. If an option was not set, the property in the AHK object will be the default value. If this value is changed, it will be as if AHKNodeJS had initialized with that option changed.
width - The width of the screen (Do not change)
height - The height of the screen (Do not change)
hotkeys - An object containing each hotkey and the function that it runs once pressed. (Do not change)
hotkeysPending - An array containing the functions that are pending to be run in a waitForInterrupt

toPercent

Converts a pair of coordinates to percentages of the screen's width and height

var percentages = ahk.toPercent([x, y]);

x - The x coordinate

y - The y coordinate

Returns - Percent of screen's width, Percent of screen's height

toPx

Converts a pair of coordinates to percentages of the screen's width and height

var percentages = ahk.toPx([x, y]);

x - The percent of the screen's width

y - The percent of the screen's height

Returns - x-coordinate, y-coordinate

setHotkey

Binds a hotkey to a function

ahk.setHotkey(hotkey, toRun, instant?);

hotkey - The object or string hotkey used in the intitialization of AHKNodeJS

toRun - An async or normal function that will be run when the hotkey is triggered and run in waitForInterrupt

instant - A boolean that determines whether or not the function will be run instantly. If this is set to true, toRun should not contain any AHK communication as it could result in two AHK functions running synchronously which would likely crash the script.

sleep

Sleeps for a certain amount of time

await ahk.sleep(ms);

ms - The amount of time to wait for in milliseconds

waitForInterrupt

Checks if any hotkeys have been pressed and executes their functions asynchronously in order from oldest hotkey pressed to newest. Once all functions have been executed, this function is resolved.

await ahk.waitForInterrupt();

mouseMove

Moves the mouse to the specified position

await ahk.mouseMove({
  x: number,
  y: number,
  speed?: number,
  positioning?: string
});

x - The x coordinate or percent of the screen's width to move to

y - The y coordinate or percent of the screen's height to move to

speed - The speed of the mouse on a range of (0 - 100). A speed of 0 will move the mouse instantly to its position, and if not specified, the mouse speed will default to the speed set by setMouseSpeed

positioning - If positioning is set to %, then x and y will be interpreted as percentages of the screen's width and height rather than coordinates

click

Clicks the mouse. If x and y are specified, the mouse will move at the speed set by setMouseSpeed. If no parameters are provided, it will perform one left click at the mouse's current position.

await ahk.click({
  x?: number,
  y?: number,
  positioning?: string,
  button?: string,
  state?: string,
  count?: number
}?);

x - The x coordinate or percent of the screen's width to click the mouse at

y - The y coordinate or percent of the screen's height to click the mouse at

positioning - If positioning is set to %, then x and y will be interpreted as percentages of the screen's width and height rather than coordinates

button - Controls which mouse button will be clicked. If button is set to left, it will left click. If button is set to middle, it will middle click. If button is set to right, it will right click. This value defaults to left.

state - Controls the state of the mouse button. If state is set to down, it will hold the mouse button down. If state is set to up, it will release the mouse button. If no state is specified, it will send the mouse button down and back up.

count - The amount of clicks that it will perform. This value defaults to one.

clickPlay

Clicks the mouse using SendPlay. It is the same as click in every other way.

await ahk.click({
  x?: number,
  y?: number,
  positioning?: string,
  button?: string,
  state?: string,
  count?: number
}?);

x - The x coordinate or percent of the screen's width to click the mouse at

y - The y coordinate or percent of the screen's height to click the mouse at

positioning - If positioning is set to %, then x and y will be interpreted as percentages of the screen's width and height rather than coordinates

count - The amount of clicks that it will perform. This value defaults to one.

clipboard

Accesses the clipboard. If value is not specified, it returns the current clipboard. If value is specified, it will set the clipboard to value.

var clipboard = await ahk.clipboard(value?);

value - The string that the clipboard will be set to

Returns - The value of the clipboard if no parameter is passed in

var found = await ahk.imageSearch({
  x1: number,
  y1: number,
  x2: number,
  y2: number,
  imgPath: string,
