## README

# A pure javascript shim for WASI

Implementation status: A subset of wasi_snapshot_preview1 is implemented. The rest either throws an exception, returns an error or is incorrectly implemented.

## Usage

```
npm install @fizx/browser_wasi_shim --save
```

```javascript
import { WASI, File, PreopenDirectory } from "@fizx/browser_wasi_shim";

let args = ["bin", "arg1", "arg2"];
let env = ["FOO=bar"];
let fds = [
    new File([]), // stdin
    new File([]), // stdout
    new File([]), // stderr
    new PreopenDirectory(".", {
        "example.c": new File(new TextEncoder("utf-8").encode(`#include "a"`)),
        "hello.rs": new File(new TextEncoder("utf-8").encode(`fn main() { println!("Hello World!"); }`)),
    }),
];
let wasi = new WASI(args, env, fds);

let wasm = await WebAssembly.compileStreaming(fetch("bin.wasm"));
let inst = await WebAssembly.instantiate(wasm, {
    "wasi_snapshot_preview1": wasi.wasiImport,
});  
wasi.start(inst);
```
