## Usage

init the wasm module before construct `TokenizerBuilder`:

```ts
import __wbg_init, { TokenizerBuilder } from 'lindera-wasm'

__wbg_init.then(() => {
    const builder = new TokenizerBuilder()
    //...
})
```

### for [Vite](https://vite.dev/) base project

You should exclude this package in the `optimizeDeps`:

```ts
// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig({
  optimizeDeps: {
    exclude: [
      "lindera-wasm"
    ]
  },
})
```

### for Browser extension development

Set the `cors` config in vite.config.js

```ts
// vite.config.js
import { defineConfig } from 'vite'

export default defineConfig({
  server: {
    cors: {
      origin: [
        /chrome-extension:\/\//,
      ],
    },
  },
})
```
