Better Auth UI

Solid package/runtime track: @better-auth-ui/solid owns provider wiring, Solid Query factories, mutation factories, and server helpers.

Use Zaidan when your job is installing copied Solid components or wiring TanStack Start app routes. Stay in this Solid section when your job is using package runtime APIs.

Quick path

Install the Solid package and Solid Query.
Create a Better Auth client with createAuthClient.
Wrap your app with AuthProvider and pass a QueryClient.
Use query and mutation option factories from @better-auth-ui/solid in your components.
Use @better-auth-ui/solid/server only at server boundaries that need server-side session data.

npm install @better-auth-ui/solid @tanstack/solid-query better-auth solid-js

Package exports

Export	Owns
`@better-auth-ui/solid`	`createAuthClient`, `AuthProvider`, `useAuth`, auth config types, provider icons, query factories, mutation factories, and hooks such as `useSession`.
`@better-auth-ui/solid/server`	Server-safe query helpers and auth server types for SSR boundaries.

What belongs elsewhere

Component installation, generated payloads, and copied-file ownership belong in Zaidan.
TanStack Start app setup belongs in Zaidan integrations.
Native Solid email templates are documented in Zaidan Email; React render-hook behavior and HeroUI React components are not Solid package APIs.
Registry generation is part of the Solid example + Zaidan docs, not this package reference.

Queries

Review Solid Query factories, cache keys, and loader helpers.

Mutations

Use mutation option factories for Better Auth write endpoints.

SSR

Use server-safe helpers to prefetch session data at SSR boundaries.
