# TypeScript SDK

> SDK for JavaScript runtimes (Node.js and browsers)

### Quickstart

```bash theme={null}
pnpm add @polar-sh/sdk
```

```typescript theme={null}
import { Polar } from '@polar-sh/sdk'

const polar = new Polar({
  accessToken: process.env['POLAR_ACCESS_TOKEN'] ?? '',
})

async function run() {
  const result = await polar.users.benefits.list({})

  for await (const page of result) {
    // Handle the page
    console.log(page)
  }
}

run()
```

<Note>
  **camelCase vs. snake\_case**

  Our API (and docs) is designed with `snake_case`. However, our TS SDK currently
  converts this to camelCase to follow JS/TS convention. You should automatically
  see the camelCase parameters suggested in modern IDEs due to typing, but it's
  worth keeping in mind switching between code & docs.

  We aim to introduce the ability to toggle this in the future, i.e using
  `snake_case` even in TypeScript to more easily map it to our documentation and
  design of the API itself.

### Framework Adapters

Implement Checkout & Webhook handlers in 5 lines of code.

* [Next.js](/integrate/sdk/adapters/nextjs)
* [Astro](/integrate/sdk/adapters/astro)
* [Remix](/integrate/sdk/adapters/remix)
* [Sveltekit](/integrate/sdk/adapters/sveltekit)
* [Deno](/integrate/sdk/adapters/deno)
* [Elysia](/integrate/sdk/adapters/elysia)
* [Express](/integrate/sdk/adapters/express)
* [Fastify](/integrate/sdk/adapters/fastify)
* [Hono](/integrate/sdk/adapters/hono)

### Sandbox Environment

You can configure the SDK so it hits the [sandbox environment](/integrate/sandbox) instead of the production one. You just need to add the `server` property to the configuration object:

```typescript theme={null}
const polar = new Polar({
  server: 'sandbox',
  accessToken: process.env['POLAR_ACCESS_TOKEN'] ?? '',
})
```
