What this skill does

# Better Auth Integrations

## Goals
- Mount the Better Auth handler at `/api/auth/*` (or a custom base path).
- Use framework helpers where available.
- Ensure cookies and headers flow correctly in SSR and server actions.

## Quick start
1. Create an `auth` instance (see `better-auth-core`).
2. Add a catch-all route for `/api/auth/*`.
3. Use a framework helper (or `auth.handler`) to return a Response.

### Next.js App Router
```ts
import { auth } from "@/lib/auth";
import { toNextJsHandler } from "better-auth/next-js";

export const { GET, POST } = toNextJsHandler(auth);
```

### Next.js Pages Router
```ts
import { auth } from "@/lib/auth";
import { toNodeHandler } from "better-auth/node";

export const config = { api: { bodyParser: false } };
export default toNodeHandler(auth.handler);
```

## Cookie handling in Next.js server actions
Use the `nextCookies` plugin so server actions set cookies correctly.

```ts
import { betterAuth } from "better-auth";
import { nextCookies } from "better-auth/next-js";

export const auth = betterAuth({
  // ...config
  plugins: [nextCookies()],
});
```

## Guardrails
- Keep the base path consistent between server and client.
- Prefer framework helpers when available.
- Avoid running custom body parsers before the auth handler.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

Process documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
