# JavaScript SDK
Use this sub-skill when the user wants to use `r2r-js` from Node or a browser, handle camelCase payloads, or work with streamed responses in JavaScript.
## What it owns
- client construction and auth/token refresh helpers
- Node vs browser file upload and download behavior
- retrieval, documents, graphs, collections, and user calls from JS
- streaming response handling and casing differences
## Start here
```javascript
const { r2rClient } = require("r2r-js");
const client = new r2rClient("http://localhost:7272");
```
