Function consolePrinter

Create a console printer that can be used as an overlay of WASI imports. See the example below for how to use it.

const imports = {
 "wasi_snapshot_preview1": wasi.wasiImport,
}
const printer = consolePrinter();
printer.addToImports(imports);

const instance = await WebAssembly.instantiate(module, imports);
printer.setMemory(instance.exports.memory);
Copy

Note that the stdout and stderr functions are called with text, not bytes. This means that bytes written to stdout/stderr will be decoded as UTF-8 and then passed to the stdout/stderr functions every time a write occurs without buffering.
