# wasi
This module provides an implementation of the WebAssembly System Interface
## Supported Syscalls
## Usage
```typescript
import WASI from "https://deno.land/std/wasi/snapshot_preview1.ts";
const wasi = new WASI({
args: Deno.args,
env: Deno.env,
});
const binary = Deno.readAll("path/to/your/module.wasm");
const module = await WebAssembly.compile(binary);
const instance = await WebAssembly.instantiate(module, {
wasi_snapshot_preview1: wasi.exports,
});
wasi.memory = module.exports.memory;
if (module.exports._start) {
instance.exports._start();
} else if (module.exports._initialize) {
instance.exports._initialize();
} else {
throw new Error("No entry point found");
}
```
## Testing
The test suite for this module spawns rustc processes to compile various example
Rust programs. You must have wasm targets enabled:
```
rustup target add wasm32-wasi
rustup target add wasm32-unknown-unknown
```
