# SolidStart

> Integrate Timeback with SolidStart

## Overview

The Timeback SDK provides a SolidStart adapter using middleware.

## Installation

<CodeGroup>
  ```bash npm theme={null}
  npm install @timeback/sdk
  ```

  ```bash pnpm theme={null}
  pnpm add @timeback/sdk
  ```

  ```bash yarn theme={null}
  yarn add @timeback/sdk
  ```

  ```bash bun theme={null}
  bun add @timeback/sdk
  ```
</CodeGroup>

## Server Setup

Create a Timeback instance:

```typescript src/lib/timeback.ts theme={null}
import { createTimeback } from '@timeback/sdk'

export const timeback = await createTimeback({
	env: 'staging',
	api: {
		clientId: process.env.TIMEBACK_API_CLIENT_ID!,
		clientSecret: process.env.TIMEBACK_API_CLIENT_SECRET!,
	},
	identity: {
		mode: 'sso',
		clientId: process.env.AWS_COGNITO_CLIENT_ID!,
		clientSecret: process.env.AWS_COGNITO_CLIENT_SECRET!,
		redirectUri: 'http://localhost:3000/api/timeback/identity/callback',
		onCallbackSuccess: async ({ user, state, redirect }) => {
			await setSession({ id: user.id, email: user.email })
			return redirect(state?.returnTo ?? '/')
		},
		onCallbackError: ({ error, redirect }) => {
			return redirect('/?error=sso_failed')
		},
		getUser: () => getSession(),
	},
})
```

## Middleware

Create middleware to handle Timeback routes:

```typescript src/middleware.ts theme={null}
import { createMiddleware } from '@solidjs/start/middleware'
import { solidStartHandler } from '@timeback/sdk/solid-start'
import { timeback } from '~/lib/timeback'

export default createMiddleware({
	onRequest: [
		async event => {
			const response = await solidStartHandler({
				timeback,
				event,
			})
			if (response) return response
		},
	],
})
```

## Alternative: Route-Based Handler

For more control, you can use a route-based approach instead of middleware:

```typescript src/routes/api/timeback/[...path].ts theme={null}
import { toSolidStartHandler } from '@timeback/sdk/solid-start'
import { timeback } from '~/lib/timeback'

const handlers = toSolidStartHandler(timeback)

export const GET = handlers.GET
export const POST = handlers.POST
```

## Client Provider

Wrap your app with the TimebackProvider:

```tsx src/app.tsx theme={null}
import { TimebackProvider } from '@timeback/sdk/solid'

export default function App() {
	return (
		<TimebackProvider>
			<Router root={props => <Suspense>{props.children}</Suspense>}>
				<FileRoutes />
			</Router>
		</TimebackProvider>
	)
}
```

## Usage

<Tip>
  For the full client-side API, see the [Solid client
  adapter](/beta/build-on-timeback/sdk/client/solid).
</Tip>

Use primitives in components:

```tsx src/components/UserStatus.tsx theme={null}
import { SignInButton, useTimeback } from '@timeback/sdk/solid'
import { Show } from 'solid-js'

export function UserStatus() {
	const timeback = useTimeback()

	return (
		<Show when={timeback} fallback={<SignInButton size="lg">Sign In</SignInButton>}>
			<div>Welcome!</div>
		</Show>
	)
}
```
