#### TypeScript Go support

TypeScript Go support is powered by `ts-checker-rspack-plugin`'s experimental, CLI-based integration for [typescript-go](https://github.com/microsoft/typescript-go). It runs the `tsgo` binary for type checking and can reduce type-checking time by about 5-10x.

To enable it, install `@typescript/native-preview` and set `typescript.tsgo` to `true`:

```ts
pluginTypeCheck({
tsCheckerOptions: {
typescript: {
tsgo: true,
},
},
});
```

When `tsgo` is enabled, the default `typescript.typescriptPath` resolves to `@typescript/native-preview/package.json`. If you set `typescript.typescriptPath` manually in `tsgo` mode, it must be an absolute path to `@typescript/native-preview/package.json`.

For supported options and limitations, see [ts-checker-rspack-plugin - TypeScript Go support](https://github.com/rstackjs/ts-checker-rspack-plugin#typescript-go-support).

#### Object Type

When the value of `tsCheckerOptions` is an object, it will be deeply merged with the default configuration.
