Import#

Form: The wrapper component that manages context and state.

import { Form } from '@saas-ui/react' // default form
import { Form } from '@saas-ui/forms/zod' // zod form
import { Form } from '@saas-ui/forms/yup' // yup form

Usage#

When you supply a schema to Form and don't supply any children, the form will automatically render the fields.

The default Form component supports the following schema format.

Object schema#

The object schema is an object with field props. Array and object fields can have nested fields.

import { Form, ObjectSchema } from '@saas-ui/react'

const schema = {
  title: {
    label: 'Title',
    rules: {
      required: true,
    },
  },
  body: {
    label: 'Body',
    type: 'textarea',
  },
} as const satisfies ObjectSchema

export default function Task() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        body: '',
      }}
      onSubmit={(params) => alert(params)}
    />
  )
}

Customize submit button#

import { Form, ObjectSchema  } from '@saas-ui/react'

const schema = {
  title: {
    label: 'Title',
    rules: {
      required: true,
    },
  },
  body: {
    label: 'Body',
    type: 'textarea',
  },
} as const satisfies ObjectSchema

export default function Post() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        body: '',
      }}
      onSubmit={(params) => alert(params)}
      fields={{
        submit: {
          children: 'Save post',
          variant: 'outline',
          colorScheme: 'cyan',
        },
      }}
    />
  )
}

Object field#

import { Form, ObjectSchema } from '@saas-ui/react'

const schema = {
  title: {
    label: 'Title',
    rules: {
      required: true,
    },
  },
  body: {
    label: 'Body',
    type: 'textarea',
  },
  author: {
    type: 'object',
    label: 'Author',
    properties: {
      name: {
        label: 'Name',
      },
      email: {
        label: 'Email',
      },
    },
  },
} as const satisfies ObjectSchema

export default function Post() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        body: '',
        'author.name': 'Eelco',
        'author.email': 'eelco@saas-ui.dev',
      }}
      onSubmit={(params) => alert(params)}
      fields={{
        author: {
          type: 'object',
          columns: 2,
        },
        submit: {
          children: 'Save post',
        },
      }}
    />
  )
}

Array field#

import { Form, ObjectSchema } from '@saas-ui/react'

const schema = {
  title: {
    label: 'Title',
    rules: {
      required: true,
    },
  },
  body: {
    label: 'Body',
    type: 'textarea',
  },
  tags: {
    type: 'array',
    label: 'Tags',
    items: {
      type: 'object',
      properties: {
        tag: {
          label: 'Tag',
        },
      },
    },
  },
} as const satisfies ObjectSchema

export default function Post() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        body: '',
        tags: [{ tag: 'react' }, { tag: 'typescript' }],
      }}
      onSubmit={(params) => alert(params)}
      fields={{
        submit: {
          children: 'Save post',
        },
      }}
    />
  )
}

Zod schema#

The describe function can to supply a label to the field. Zod currently does not support adding meta data to the schema, use the fields prop to override properties on any of the fields.

import { Form } from '@saas-ui/forms/zod'
import * as z from 'zod'

const schema = z.object({
  title: z.string().min(1).describe('Title'),
  description: z.string(),
})

export default function Post() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        description: '',
      }}
      onSubmit={() => null}
      fields={{
        description: {
          label: 'Description',
          type: 'textarea',
        },
        submit: {
          children: 'Save post',
        },
      }}
    />
  )
}

Yup schema#

The label function can to supply a label to the field. Using the meta function you can configure the type of fields.

import { Form } from '@saas-ui/forms/yup'
import * as yup from 'yup'

const schema = yup.object().shape({
  title: yup.string().required().label('Title'),
  description: yup.string().label('Description').meta({ type: 'textarea' }),
})

export default function Post() {
  return (
    <Form
      schema={schema}
      defaultValues={{
        title: '',
        description: '',
      }}
      onSubmit={() => null}
      fields={{
