This example runs a WebAssembly program compiled using AssemblyScript, built
with npm install && npm run build
.
AssemblyScript program exports two functions, hello_world
which executes
simple math, and goodbye_world
, which throws an error that is logged using
AssemblyScript abort
built-in function.
This demo configures AssemblyScript imports for errors and trace messages.
$ go run assemblyscript.go 7
hello_world returned: 10
sad sad world at index.ts:7:3
Note: index.ts avoids use of JavaScript functions that use
I/O, such as console.log. If your code uses these, compile your code with
the wasi-shim and configure in wazero using
wasi_snapshot_preview1.Instantiate
.
