## 如何运行
第 0 步，安装 `wasm-pack`
[https://rustwasm.github.io/wasm-pack](https://rustwasm.github.io/wasm-pack)
第 1 步，编译 `osmos-wasm`
```bash
cd osmos-wasm
wasm-pack build --out-dir ../osmos-web/osmos-wasm
```
第 2 步，进入 `osmos-web` 安装依赖并运行
```bash
cd osmos-web
yarn
yarn dev
```

```
## Vite WASM
1. Install `vite-plugin-wasm` & `vite-plugin-top-level-await`
```bash
yarn add -D vite-plugin-wasm vite-plugin-top-level-await
```
2. Edit `vite.config.js`
```js
import { defineConfig } from 'vite'
import wasm from 'vite-plugin-wasm'
import topLevelAwait from 'vite-plugin-top-level-await'
export default defineConfig({
plugins: [
wasm(),
topLevelAwait(),
]
})
```
