    npm version license Node CI

    elgato-stream-deck is a Node.js library for interfacing with the various models of the Elgato Stream Deck.

    Please note that node-elgato-stream-deck is NOT a standalone application. It is not something you download and run on its own. It is not an alternative to the official Stream Deck program provided by Elgato. Instead, node-elgato-stream-deck is a code library which provides an API to the Stream Deck. Developers can use this API to make their own applications which interface with the Stream Deck.

    To further clarify: this is not an installable program. There is no user interface, and you cannot do anything with this library on its own. Out of the box, this library does nothing. It's purpose is to provide tools for programmers to build programs from the ground up which interact with a Stream Deck.

    This is a tool for developers to use. It is not a program for end users. It cannot and will not replace the official Stream Deck program. That is not its goal. However, it does enable someone to more easily write a program which does do that.


    $ npm install --save elgato-stream-deck

    $ npm install --save @julusian/jpeg-turbo@^1.0.0 (Optional)

    It is recommended to install @julusian/jpeg-turbo to greatly improve performance for writing images to the StreamDeck XL or the Original-v2. Without doing so jpeg-js will be used instead, but image transfers will be noticably more cpu intensive and slower. jpeg-turbo has prebuilt binaries, but is not installed by default to ensure installation is easy for users who do not need the performance or the XL or the Original-v2.


    On linux, the udev subsystem blocks access to the StreamDeck without some special configuration. Save the following to /etc/udev/rules.d/50-elgato.rules and reload the rules with sudo udevadm control --reload-rules

    SUBSYSTEM=="input", GROUP="input", MODE="0666"
    SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="0060", MODE:="666", GROUP="plugdev"
    SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="0063", MODE:="666", GROUP="plugdev"
    SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="006c", MODE:="666", GROUP="plugdev"
    SUBSYSTEM=="usb", ATTRS{idVendor}=="0fd9", ATTRS{idProduct}=="006d", MODE:="666", GROUP="plugdev"

    Unplug and replug the device and it should be usable

    Native dependencies

    All of this library's native dependencies ship with prebuilt binaries, so having a full compiler toolchain should not be necessary to install node-elgato-stream-deck.

    However, in the event that installation does fail (or if you are on a platform that our dependencies don't provide prebuilt binaries for, such as a Raspberry Pi), you will need to install a compiler toolchain to enable npm to build some of node-elgato-stream-deck's dependencies from source. Expand the details block below for full instructions on how to do so.

    Compiling dependencies from source
    • Windows
      npm install --global windows-build-tools
    • MacOS
      • Install the Xcode Command Line Tools:
      xcode-select --install
    • Linux (including Raspberry Pi)
      • Follow the instructions for Linux in the "Compiling from source" steps for
      • Try installing node-elgato-stream-deck
      • If you still have issues, ensure everything is updated and try again:
        sudo apt-get update && sudo apt-get upgrade

    const path = require('path')
    const { openStreamDeck } = require('elgato-stream-deck')
    // Automatically discovers connected Stream Decks, and attaches to the first one.
    // Throws if there are no connected stream decks.
    // You also have the option of providing the devicePath yourself as the first argument to the constructor.
    // For example: const myStreamDeck = new StreamDeck('\\\\?\\hid#vid_05f3&pid_0405&mi_00#7&56cf813&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}')
    // On linux the equivalent would be: const myStreamDeck = new StreamDeck('0001:0021:00')
    // Available devices can be found with listStreamDecks()
    const myStreamDeck = openStreamDeck()

    > openStreamDeck(path?: string, options?: OpenStreamDeckOptions) -> StreamDeckDeviceInfo | undefined

    Opens a StreamDeck.

    If a path is provided, then a specific device will be opened, otherwise the first found device will be used. See listDevices for info on how to discover devices.

    Some device types have additional options, as part of the options object. This is not required to be provided.


    • useOriginalKeyOrder: This restores the right-to-left key order for the Original StreamDeck. Since v3.0.0 the default key order has been changed to make sense and be consistent with the other models
    const streamDeck = openStreamDeck()
    // Or
    const streamDeck = openStreamDeck('0001:0021:00')
    // Or
    const streamDeck = openStreamDeck('0001:0021:00', {
    	useOriginalKeyOrder: true,

    > listStreamDecks() -> Array<StreamDeckDeviceInfo>

    This will scan for and list all detected StreamDeck devices on the system along with their model. The path property can be passed into the constructor to open a specific device.

    console.log('Devices: ', listStreamDecks())
     * Devices: [
     *   {
     *     model: 'original',
     *     path: '0001:0023:00',
     *     serialNumber: 'AL37G1A02840'
     *   },
     *   {
     *     model: 'xl',
     *     path: '0001:0021:00',
     *     serialNumber: 'CL18I1A00913'
     *   }
     * ]

    > getStreamDeckInfo(path: string) -> StreamDeckDeviceInfo | undefined

    Get the info for a given device. Returns undefined if the path is not a valid StreamDeck

    console.log('Info: ', getStreamDeckInfo('0001:0021:00'))
     * Info: {
     *   model: 'xl',
     *   path: '0001:0021:00',
     *   serialNumber: 'CL18I1A00913'
     * }

    > streamDeck.fillColor(keyIndex, r, g, b) -> undefined

    Synchronously sets the given keyIndex's screen to a solid RGB color. An error will be thrown if the keyIndex is not valid, of a colour component is outside of the range 0-255

    // Turn key 4 (the top left key) solid red.
    streamDeck.fillColor(4, 255, 0, 0)

    > streamDeck.fillImage(keyIndex, buffer) -> undefined

    Synchronously writes a buffer of RGB image data to the given keyIndex's screen. The required size of the buffer varies by device, and must be the exact length. Any other length will result in an error being thrown.

    The expected sizes are:

    • Original: 15552 (72px)
    • Mini: 19200 (80px)
    • XL: 27648 (96px)
    // Fill the third button from the left in the first row with an image of the GitHub logo.
    const sharp = require('sharp') // See for full docs on this great library!
    sharp(path.resolve(__dirname, 'github_logo.png'))
    	.flatten() // Eliminate alpha channel, if any.
    	.resize(streamDeck.ICON_SIZE, streamDeck.ICON_SIZE) // Scale up/down to the right size, cropping if necessary.
    	.raw() // Give us uncompressed RGB.
    	.then((buffer) => {
    		streamDeck.fillImage(2, buffer)
    	.catch((err) => {

    > streamDeck.fillPanel(buffer) -> undefined

    Applies an image to the entire panel, spreading it over all keys. The image must be exactly the correct resolution for your device. Any other size will result in an error being thrown.

    // Fill the entire panel with a photo of a sunny field.
    const sharp = require('sharp') // See for full docs on this great library!
    sharp(path.resolve(__dirname, 'github_logo.png'))
    	.flatten() // Eliminate alpha channel, if any.
    	.resize(streamDeck.ICON_SIZE * streamDeck.KEY_COLUMNS, streamDeck.ICON_SIZE * streamDeck.KEY_ROWS) // Scale up/down to the right size, cropping if necessary.
    	.raw() // Give us uncompressed RGB.
    	.then((buffer) => {
    	.catch((err) => {

    > streamDeck.clearKey(keyIndex) -> undefined

    Synchronously clears the given keyIndex's screen. An error will be thrown if the keyIndex is not valid

    // Clear the third button from the left in the first row.

    > streamDeck.clearAllKeys() -> undefined

    Synchronously clears all keys on the device.

    // Clear all keys.

    > streamDeck.setBrightness(percentage) -> undefined

    Synchronously set the brightness of the Stream Deck. This affects all keys at once. The brightness of individual keys cannot be controlled. An error will be thrown if the brightness is not in the range 0-100

    // Set the Stream Deck to maximum brightness

    > streamDeck.resetToLogo() -> undefined

    Resets the device back to the startup Elgato logo.

    // Set the Stream Deck back to the Elgato logo

    > streamDeck.getFirmwareVersion() -> string

    Gets the firmware version number.


    > streamDeck.getSerialNumber() -> string

    Gets the serial number of the device.



    > down

    Fired whenever a key is pressed. keyIndex is the index of that key.

    streamDeck.on('down', (keyIndex) => {
    	console.log('key %d down', keyIndex)

    > up

    Fired whenever a key is released. keyIndex is the index of that key.

    streamDeck.on('up', (keyIndex) => {
    	console.log('key %d up', keyIndex)

    > error

    Fired whenever an error is detected by the node-hid library. Always add a listener for this event! If you don't, errors will be silently dropped.

    streamDeck.on('error', (error) => {
