# Typings

`@leather.io/rpc` has TypeScript types for the `LeatherProvider` methods: request parameters and results.

```bash
npm install -D @leather.io/rpc
yarn add -D @leather.io/rpc
pnpm add -D @leather.io/rpc
```

The package does not change the global scope. Import the `LeatherProvider` type and declare it on `Window` yourself:

```typescript
import type { LeatherProvider } from '@leather.io/rpc';

declare global {
  interface Window {
    LeatherProvider?: LeatherProvider;
  }
}
```

`window.LeatherProvider.request` is then typed per method.
