pigpio VS node-rpio

You might be better asking on the git repo: https://github.com/joan2937/pigpio

GitHub - joan2937/pigpio: pigpio is a C library for the Raspberry which allows control of the General Purpose Input Outputs (GPIO).

Through this github, I found out I could use this to make it possible, but...(!) it needs to continue the script without exiting because it doesn't see one of the devices.

pigpio: Here is the repo, but the "abyz" link to the documentation looks to be broken. Not sure how to go about getting the daemon to work - I tried sudo pigpiod as the prompt in Python suggests, but sudo: pigpiod: command not found.

The pigpio is an actively developed library with an impressive set of features: All GPIO pins of the Raspberry Pi can be read, written to, attached to interrupt handlers, and output PWM signals at the same time. Also, UART, I2C and SPI protocols are implemented. It is written in C and also provides Python bindings. Go to the official Github repository and build the newest version on your Raspberry Pi, or install it with apt install pigpio python-pigpio python3-pigpio.

NodeJS on the Pi can access the GPIO pins - see here for an old example and a newer on here

We will need to desolder the LED display or source a compatible module. It's a Sanyo SL-1042-27T. It's a very thin module, so I suspect the driver gubbins is on a separate chip. I know very little about driving LED modules, so at this stage I don't know if I can just bit-bang it from a Node.js script or what.
