# TypeScript | Frontend

> Use @0xkey-io/core for Embedded Wallets in Angular, Vue, Svelte, or custom React UIs.

## @0xkey-io/core

[`@0xkey-io/core`](https://www.npmjs.com/package/@0xkey-io/core) is the recommended **client-side** TypeScript SDK. It provides:

* `ZeroXKeyClient` with session storage and stampers (IndexedDB, passkey, wallet)
* Auth Proxy integration for OTP, OAuth, and signup
* A typed HTTP client for all public API activities

If you use **React**, start with [`@0xkey-io/react-wallet-kit`](/sdks/react/getting-started) instead — it wraps `@0xkey-io/core` with UI and hooks.

Head to [Getting started](/sdks/typescript-frontend/getting-started) to configure Auth Proxy, install the package, and call `await client.init()`.

## Advanced stamping packages

Lower-level libraries when you need full control over request bytes:

| Package                                                                                  | Role                                |
| :--------------------------------------------------------------------------------------- | :---------------------------------- |
| [`@0xkey-io/http`](https://www.npmjs.com/package/@0xkey-io/http)                         | Typed HTTP client + activity poller |
| [`@0xkey-io/api-key-stamper`](https://www.npmjs.com/package/@0xkey-io/api-key-stamper)   | P-256 API key stamps                |
| [`@0xkey-io/webauthn-stamper`](https://www.npmjs.com/package/@0xkey-io/webauthn-stamper) | WebAuthn stamps                     |
| [`@0xkey-io/iframe-stamper`](https://www.npmjs.com/package/@0xkey-io/iframe-stamper)     | Import/export iframe stamping       |
| [`@0xkey-io/wallet-stamper`](https://www.npmjs.com/package/@0xkey-io/wallet-stamper)     | EVM / Solana wallet stamps          |

Most apps should use `@0xkey-io/core` or [`@0xkey-io/sdk-server`](/sdks/javascript-server) instead of composing these manually.

## Server-side TypeScript

Backend automation, proxies, and OTP helpers live in a separate package:

## Examples

Browse [`0xkey-io/sdk-js/examples`](https://github.com/0xkey-io/sdk-js/tree/main/examples):

* `kitchen-sink` — broad SDK surface
* `oauth` / `otp-auth` — auth flows
* `delegated-access` — backend signing
* `with-sdk-server` — minimal server Whoami
