(Note: This may work on other platforms besides linux, with real can devices, but the virtal device testing only works on linux)

Setup:

To setup the can server listener and web api, first install Go, then:

cd server
go get

Install can-utils and start a virtual can device, if testing on linux:

sudo dnf install can-utils
sudo ip link add dev vcan0 type vcan
sudo ip link set vcan0 up

For the web app, install node, then:

cd app
npm install
npm run

Run program:

To start the web api (port 8080) and can listener for the vcan0 device, run: go run main.go vcan0

Send a test frame in another terminal and see it (if can-utils are installed): cansend vcan0 123#deadbeef

See the events in the app dashboard if running: http://localhost:3000

Other stuff (later):

build wasm: GOOS=js GOARCH=wasm go build -o build/wasm/CANServer.wasm main.go

build with tinygo: GOOS=js GOARCH=wasm tinygo build -o build/wasm/CANServer.wasm main.go

Copy wasm to frontend: cp "$(go env GOROOT)/lib/wasm/wasm_exec.js" .
