A simple express server to interact with GPIO.
- node.js > 12 (Currently, I think there's a dep issue with v14).
- 1 wire interface enabled
To set up your PI for the cabinet, follow these steps.
There are 2 components, the API and the client. If you followed the above setup, they will both comeup at boot.
You can also run each independantly with live reload.
To run the API on a non-pi environment, use npm start. This defaults to using nodemon. Note, the onoff lib will not loaded, the server will run, but there will be no GPIO control. If you do not have OS support for the GPIO, and you try to use it, the server will crash.
cd ~/Sites/gpio-server/api
npm start
To enable the gpio, you have to pass OS_ENV=pi on startup. Use the following command for convience.
npm run start:pi
To run the client with nodemon ::
cd ~/Sites/gpio-server/client
npm run serve
To build to dist, and run via a lightweight http-server. (Assumes you have http-server installed globally. npm i -g http-server);
cd ~/Sites/gpio-server/client
npm run build
cd dist && http-server
Uhh. This has been a major PITA. Due to using onoff for pin interaction, I cannot create meaningful
tests for objects or services, or start the server on OSX. ( My primary dev machine. ) I'm actively working
on a solution to this problem, wether that means mocking epoll and a fs, or switching to a different
lib, like node-rpio, I'm not sure yet. But it's on my mind.
To debug the client you can enable the vue-devtools app on your local machine. Follow the steps for remote debugging.
This is the easiest thing to do.
You can also forward port 9222 on your PI, and attempt remote debugging over the chrome network inspector.
