description: How to generate pages and interfaces in Studio, a web interface for managing Supabase projects
globs:
alwaysApply: true

## Project Structure
- Next.js app using pages router
- Pages go in @apps/studio/pages
- Project related pages go in @apps/studio/pages/projects/[ref]
- Organization related pages go in @apps/studio/pages/org/[slug]
- Studio specific components go in @apps/studio/components
- Studio specific generic UI components go in @apps/studio/components/ui
- Studio specific components related to individual pages go in @apps/studio/components/interfaces e.g. @apps/studio/components/interfaces/Auth
- Generic helper functions go in @apps/studio/lib
- Generic hooks go in @apps/studio/hooks
## Component system
Our primitive component system is in @packages/ui and is based off shadcn/ui components. These components can be shared across all @apps e.g. studio and docs. Do not introduce new ui components unless asked to.
- UI components are imported from this package across apps e.g. import { Button, Badge } from 'ui'
- Some components have a _Shadcn_ namespace appended to component name e.g. import { Input*Shadcn* } from 'ui'
- We should be using _Shadcn_ components where possible
- Before composing interfaces, read @packages/ui/index.tsx file for a full list of available components
## Styling
We use Tailwind for styling.
- You should never use tailwind classes for colours and instead use classes we've defined ourselves
- Backgrounds // most of the time you will not need to define a background
- 'bg' used for main app surface background
- 'bg-muted' for elevating content // you can use Card instead
- 'bg-warning' for highlighting information that needs to be acted on
- 'bg-destructive' for highlighting issues
- Text
- 'text-foreground' for primary text like headings
- 'text-foreground-light' for body text
- 'text-foreground-lighter' for subtle text
- 'text-warning' for calling out information that needs action
- 'text-destructive' for calling out when something went wrong
- When needing to apply typography styles, read @apps/studio/styles/typography.scss and use one of the available classes instead of hard coding classes e.g. use "heading-default" instead of "text-sm font-medium"
## Page structure
When creating a new page follow these steps:
- Create the page in @apps/studio/pages
- Use the PageLayout component that has the following props
```jsx
export interface NavigationItem {
id?: string
label: string
href?: string
icon?: ReactNode
onClick?: () => void
badge?: string
active?: boolean
}
interface PageLayoutProps {
children?: ReactNode
title?: string | ReactNode
subtitle?: string | ReactNode
icon?: ReactNode
breadcrumbs?: Array<{
label?: string
href?: string
element?: ReactNode
}>
primaryActions?: ReactNode
secondaryActions?: ReactNode
navigationItems?: NavigationItem[]
className?: string
size?: 'default' | 'full' | 'large' | 'small'
isCompact?: boolean
}
```
- If a page has page related actions, add them to primary and secondary action props e.g. Users page has "Create new user" action
- If a page is within an existing section (e.g. Auth), you should use the related layout component e.g. AuthLayout
- Create a new component in @apps/studio/components/interfaces for the contents of the page
- Use ScaffoldContainer if the page should be center aligned in a container
- Use ScaffoldSection, ScaffoldSectionTitle, ScaffoldSectionDescription if the page has multiple sections
### Page example
```jsx
import { MyPageComponent } from 'components/interfaces/MyPage/MyPageComponent'
import AuthLayout from './AuthLayout'
import DefaultLayout from 'components/layouts/DefaultLayout'
import { ScaffoldContainer } from 'components/layouts/Scaffold'
import type { NextPageWithLayout } from 'types'
const MyPage: NextPageWithLayout = () => {
return (
<ScaffoldContainer>
<MyPageComponent />
</ScaffoldContainer>
)
}
MyPage.getLayout = (page) => (
<DefaultLayout>
<AuthLayout>{page}</AuthLayout>
</DefaultLayout>
)
export default MyPage
export const MyPageComponent = () => (
<ScaffoldSection isFullWidth>
<div>
<ScaffoldSectionTitle>My page section</ScaffoldSectionTitle>
<ScaffoldSectionDescription>A brief description of the purpose of the page</ScaffoldSectionDescription>
</div>
// Content goes here
</ScaffoldSection>
)
```
## Forms
- Build forms with `react-hook-form` + `zod`.
- Use our `_Shadcn_` form primitives from `ui` and prefer `FormItemLayout` with layout="flex-row-reverse" for most controls (see `apps/studio/components/interfaces/Settings/Integrations/GithubIntegration/GitHubIntegrationConnectionForm.tsx`).
- Keep imports from `ui` with `_Shadcn_` suffixes.
- Forms should generally be wrapped in a Card unless specified
### Example (single field)
```tsx
import { zodResolver } from '@hookform/resolvers/zod'
import { useForm } from 'react-hook-form'
import * as z from 'zod'
import { Button, Form_Shadcn_, FormField_Shadcn_, FormControl_Shadcn_, Input_Shadcn_ } from 'ui'
import { FormItemLayout } from 'ui-patterns/form/FormItemLayout/FormItemLayout'
const profileSchema = z.object({
username: z.string().min(2, 'Username must be at least 2 characters'),
})
export function ProfileForm() {
const form = useForm<z.infer<typeof profileSchema>>({
resolver: zodResolver(profileSchema),
defaultValues: { username: '' },
mode: 'onSubmit',
reValidateMode: 'onBlur',
})
function onSubmit(values: z.infer<typeof profileSchema>) {
// handle values
}
return (
<Form_Shadcn_ {...form}>
<form onSubmit={form.handleSubmit(onSubmit)} className="space-y-4">
<Card>
<CardContent className="space-y-6">
<FormField_Shadcn_
control={form.control}
name="username"
render={({ field }) => (
<FormItemLayout
layout="flex-row-reverse"
label="Username"
description="This is your public display name."
>
<FormControl_Shadcn_>
<Input_Shadcn_ placeholder="shadcn" autoComplete="off" {...field} />
</FormControl_Shadcn_>
</FormItemLayout>
)}
/>
</CardContent>
<CardFooter className="justify-end">
<Button type="primary" htmlType="submit">
Submit
</Button>
</CardFooter>
</Card>
</form>
</Form_Shadcn_>
)
}
```
## Cards
- Use cards when needing to group related pieces of information
- Cards can have sections with CardContent
- Use CardFooter for actions
- Only use CardHeader and CardTitle if the card content has not been described by the surrounding content e.g. Page title or ScaffoldSectionTitle
- Use CardHeader and CardTitle when you are using multiple Cards to group related pieces of content e.g. Primary branch, Persistent branches, Preview branches
## Sheets
- Use a sheet when needing to reveal more complicated forms or information relating to an object and context switching away to a new page would be disruptive e.g. we list auth providers, clicking an auth provider opens a sheet with information about that provider and a form to enable, user can close sheet to go back to providers list
## Tables
- Use the generic ui table components for most tables
- Tables are generally contained witin a card
- If a table has associated actions, they should go above on right hand side
- If a table has associated search or filters, they should go above on left hand side
- If a table is the main content of a page, and it does not have search or filters, you can add table actions to primary and secondary actions of PageLayout
- If a table is the main content of a page section, and it does not have search or filters, you can add table actions to the right of ScaffoldSectionTitle
- For simple lists of objects you can use ResourceList with ResourceListItem instead
### Table example
```jsx
import { Table, TableBody, TableCaption, TableCell, TableHead, TableHeader, TableRow } from 'ui'
;<Table>
<TableCaption>A list of your recent invoices.</TableCaption>
<TableHeader>
<TableRow>
<TableHead className="w-[100px]">Invoice</TableHead>
<TableHead>Status</TableHead>
<TableHead>Method</TableHead>
<TableHead className="text-right">Amount</TableHead>
</TableRow>
</TableHeader>
<TableBody>
<TableRow>
<TableCell className="font-medium">INV001</TableCell>
<TableCell>Paid</TableCell>
<TableCell>Credit Card</TableCell>
<TableCell className="text-right">$250.00</TableCell>
</TableRow>
</TableBody>
</Table>
```
## Alerts
- Use Admonition component to alert users of important actions or restrictions in place
- Place the Admonition either at the top of the contents of the page (below page title) or at the top of the related ScaffoldSection , below ScaffoldTitle
- Use sparingly
### Alert example
```jsx
<Admonition
type="note"
title="No authentication logs available for this user"
description="Auth events such as logging in will be shown here"
/>
```
