AssemblyScript example

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.
