Go on Embedded Systems and WebAssembly

nasretdinov

Tinygo made a lot of progress over the years -- e.g. they've recently introduced macOS support! It does indeed produce much smaller binaries, including for macOS. yuriy@MacBookAir ~/t/tinygo> time tinygo build -o test-tiny main.go ________________________________________________________ Executed in 1.06 secs fish external usr time 1.18 secs 0.31 millis 1.18 secs sys time 0.18 secs 1.50 millis 0.18 secs yuriy@MacBookAir ~/t/tinygo> time go build -o test-normal main.go ________________________________________________________ Executed in 75.79 millis fish external usr time 64.06 millis 0.41 millis 63.64 millis sys time 96.76 millis 1.75 millis 95.01 millis yuriy@MacBookAir ~/t/tinygo> ll total 5096 -rw-r--r--@ 1 yuriy staff 74B 3 Apr 19:17 main.go -rwxr-xr-x@ 1 yuriy staff 2.3M 3 Apr 19:18 test-normal* -rwxr-xr-x@ 1 yuriy staff 192K 3 Apr 19:18 test-tiny* yuriy@MacBookAir ~/t/tinygo> cat main.go package main import "fmt" func main() { fmt.Printf("Hello world!\n") }

Writing embedded code with an async-aware programming language is wonderful (see Rust's embassy), but wonder how competitive this is when you need to push large quantities of data through a micro controller, I presume this is not suitable for real-time stuff?

We're using TinyGo and the Wazero runtime for our WASM plugin system in ServiceRadar, highly recommend both if you're using golang.

What are the tradeoffs compared to standard Go?

TinyGo doesnt have networking in WASI[0] and the WASM websocket module[1] was last updated 5 years ago. Go without stdlib is not Go. [0] https://github.com/tinygo-org/tinygo/issues/4880 [1] https://github.com/Nerzal/tinywebsocket

Could we compile tailscale with tinygo to run it on openwrt? Last time I checked tailscale was too large for 8MB flash routers

Does it support ESP32
