Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Readme
elgato-stream-deck
is a Node.js library for interfacing
with 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 developers can use to make their own applications which interface with the Stream Deck.
$ npm install --save elgato-stream-deck
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.

// 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}')

});

// Fill the second button from the left in the first row with an image of the GitHub logo.
// This is asynchronous and returns a promise.
myStreamDeck.fillImageFromFile(3, path.resolve(__dirname, 'github_logo.png')).then(() => {
console.log('Successfully wrote a GitHub logo to key 3.');
});
// Fill the first button form the left in the first row with a solid red color. This is synchronous.
myStreamDeck.fillColor(4, 255, 0, 0);
console.log('Successfully wrote a red square to key 4.');
import StreamDeck = require('elgato-stream-deck');

All participants and maintainers in this project are expected to follow Code of Conduct, and just generally be kind to each other.
Please refer to the Changelog for project history details, too.
> streamDeck.write(buffer) -> undefined
Synchronously writes an arbitrary Buffer
instance to the Stream Deck.
Throws if an error is encountered during the write operation.
// Writes 16 bytes of zero to the Stream Deck.
streamDeck.write(Buffer.alloc(16));
> streamDeck.fillColor(keyIndex, r, g, b) -> undefined
Synchronously sets the given keyIndex
's screen to a solid RGB color.
// Turn key 4 (the top left key) solid red.
streamDeck.fillColor(4, 255, 0, 0);
> streamDeck.fillImageFromFile(keyIndex, filePath) -> Promise
Asynchronously reads an image from filePath
and sets the given keyIndex
's screen to that image.
Automatically scales the image to 72x72 and strips out the alpha channel.
If necessary, the image will be center-cropped to fit into a square.
// Fill the second button from the left in the first row with an image of the GitHub logo.
streamDeck.fillImageFromFile(3, path.resolve(__dirname, 'github_logo.png'))
.then(() => {
console.log('Successfully wrote a GitHub logo to key 3.');
})
.catch(err => {
console.error(err);
});
> streamDeck.fillImage(keyIndex, buffer) -> undefined
Synchronously writes a buffer of 72x72 RGB image data to the given keyIndex
's screen.
The buffer must be exactly 15552 bytes in length. Any other length will result in an error being thrown.
// Fill the third button from the left in the first row with an image of the GitHub logo.
const sharp = require('sharp'); // See http://sharp.dimens.io/en/stable/ 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.
.toBuffer()
.then(buffer => {
return streamDeck.fillImage(2, buffer);
})
.catch(err => {
console.error(err);
});
> streamDeck.fillPanel(imagePathOrBuffer[, sharpOptions]) -> Promise
Asynchronously applies an image to the entire panel, spreading it over all keys. The image is scaled down and center-cropped to fit. This method does not currently account for the gaps between keys, and behaves as if each key was directly connected to its neighbors. If you wish to account for the gaps between keys, you'll need to do so via other means, and bake that into the image you provide to fillPanel
.
This method accepts either a path to an image on the disk, or a buffer. The image or path or buffer is passed directly to sharp
. Therefore, this method accepts all images and buffers which sharp
can accept.
// Fill the second button from the left in the first row with an image of the GitHub logo.
streamDeck.fillPanel(path.resolve(__dirname, 'examples/fixtures/sunny_field.png'))
.then(() => {
console.log('Successfully filled the panel with an image.');
})
.catch(err => {
console.error(err);
});
> streamDeck.clearKey(keyIndex) -> undefined
Synchronously clears the given keyIndex
's screen.
> streamDeck.clearAllKeys() -> undefined
Synchronously clears all keys on the device.
// Clear the third button from the left in the first row.
streamDeck.clearKey(2);
> 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.
// Set the Stream Deck to maximum brightness
streamDeck.setBrightness(100);
> down
Fired whenever a key is pressed. keyIndex
is the 0-14 numerical index of that key.
streamDeck.on('down', keyIndex => {
console.log('key %d down', keyIndex);
});
> up
Fired whenever a key is released. keyIndex
is the 0-14 numerical 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 => {
console.error(error);
});
Raw protocol notes can be found in NOTES.md. These detail the protocol and method for interacting with the Stream Deck which this module implements.
