The wazero CLI can be used to execute a standalone WebAssembly binary.
$ go install github.com/tetratelabs/wazero/cmd/wazero@latest
The wazero CLI accepts a single argument, the path to a WebAssembly binary. Arguments can be passed to the WebAssembly binary itself after the path.
wazero run calc.wasm 1 + 2
In addition to arguments, the WebAssembly binary has access to stdout, stderr, and stdin.
