# Wasmts
Wasm Runtime written in TypeScript.
This project is just for my learning purpose.
## How to Use
### GCD
```javascript
$ deno
Deno 1.8.2
exit using ctrl+d or close()
> const Wasmts = await import("./bundle/wasm.js")
undefined
> const code = await Deno.readFile("./test/data/wasm/gcd.wasm")
undefined
> const instance = Wasmts.instantiate(code)
undefined
> instance.exports.gcd(42, 12)
6
> instance.exports.gcd(42, 28)
14
> close()
$
```
(See [test/data/wasm/gcd.wat](test/data/wasm/gcd.wat))
### importObjects
```javascript
$ deno
Deno 1.8.2
exit using ctrl+d or close()
> const Wasmts = await import("./bundle/wasm.js")
undefined
> const code = await Deno.readFile("./test/data/wasm/import2.wasm")
undefined
> const instance = Wasmts.instantiate(code, {
env: { mul: (n, m) => n * m }
})
undefined
> instance.exports.mul(6, 7)
42
> close()
$
```
(See [test/data/wasm/import2.wat](test/data/wasm/import2.wat))
