# Installation

## Package Manager

:::code-group

```

```bash [yarn]

## Browser (CDN)

For browser use without a bundler:

```html
<script src="node_modules/casper-js-sdk/dist/lib.web.js"></script>
<script>
  const { RpcClient, HttpHandler } = CasperJsSdk;
</script>
```

## TypeScript Setup

The SDK ships with full TypeScript declarations (`dist/index.d.ts`). No `@types/casper-js-sdk` package is needed.

Minimum TypeScript version: **4.9**.

Recommended `tsconfig.json` settings:

```json
{
  "compilerOptions": {
    "target": "ES2020",
    "lib": ["ES2020"],
    "module": "CommonJS",
    "moduleResolution": "node",
    "strict": true,
    "esModuleInterop": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  }
}
```

:::note
`experimentalDecorators` and `emitDecoratorMetadata` are required for the TypedJSON decorators used in serialization classes.
