StreamDeck

Simple server that captures raw keyboard inputs and broadcasts them via socket and OSC.
Made for my Raspberry PI zero W, the peripheral's name is configured here.
Also, the binary data from my periphal may not be the same as yours, i'm using the REiiE Mini H9+ bluetooth keyboard.

Once server is running (read everything bellow first) it provides a webpage that should log keyboard events at this url :
http://IP_OF_YOUR_RASPBERRY_PI:3013

Project setup

> npm install

Install PM2 globally (will run the script as a service) :

> npm i -g pm2

Project dev/build

Compile front with hot-reloads for development

> npm run front/serve

Compile front for production

> npm run front/build

Compile server with hot-reloads for development

> npm run server/watch

Compile server for production

> npm run server/build

Shortcut for developpement

> npm run dev

Starts front and server with hot reload.
Node process has to be started manually. See Starting services section.

Compile server+front for production

> npm run build

Starting services

Execute this inside project folder's root

> pm2 start bootstrap-pm2.json

To view process logs via PM2, execute :

> pm2 logs --raw StreamDeck

Start on boot (DOESN'T work on windows)

First start the client as explained above.
Then execute these commands:

> pm2 save
> pm2 startup

Now, the service should automatically start on boot

Configuring Keyboard

The keyboard's name and path is configured there.
Yours might be different. Plug your keyboard an list the available devices with this command :

> ls -la /dev/input/by-id/

The keyboard device might endup with "kbd".
Not sure it's necessary but you may want to give access to that device to the user pi :

> sudo setfacl -m u:pi:r /dev/input/by-id/usb-0513_0318-event-kbd

(replace the device's name by yours)

Deploy and run project on Raspberry

Build the project via :

> npm run build

Put the files from the server/ folder anywhere you like on your raspberry.
Put the package.json file next to these files and run this to install dependencies:

> npm install

Create a public/ folder in the same place and put the content of the dist/ folder inside it.
Create an env.conf file still in the same place and just write prod inside it.

Run the server either manually or via PM2 (see above):

> node bootstrap.js

Open this URL on your browser and if everything's ok you should see keyboard events live like bellow:
