⚡️ Gearbox Sanity Schema Tool

Fully typed Sanity plugin to make writing Sanity schema faster and better with thoughtful defaults, succinct field definition syntax, and useful helpers. Built on top of Sanity's defineField functions to benefit from their improved DX.

Features:

• Shorthand syntax for defining fields (ie. F.slug(), F.string({ name: 'Foo' }))
• Custom fields for common schema use cases
• group and fieldset helpers to make grouping fields simple and clear
• Configurable default schema values for schema types
• Extendible custom schema types (ie. F.dropdown())

Installation

yarn

yarn add @gearbox-built/sanity-schema-tool

npm

npm install @gearbox-built/sanity-schema-tool

Usage

By default, this plugin doesn't require any initialization. Custom configuration is handled via a Higher-Order Function (HOF). Adding the plugin to the sanity.config.ts (or .js) config is not required.

Import @gearbox-built/sanity-schema-tool to start using. Exports are organized by field types:

• F: Fields
• FS: Fieldsets
• G: Groups
• P: Preview
• V: Validation

Simple Example

https://www.sanity.io/docs/document-type

import {F} from `@gearbox-built/sanity-schema-tool`

export const movie = F.document({
  name: 'movie',
  fields: [
    F.title(),
    F.image({ name: 'poster' }),
    F.array({ name: 'directors', of: [F.string()]})
  ]
})

export const movie = {
  title: 'Movie',
  name: 'movie',
  type: 'document',
  fields: [
    {
      title: 'Title',
      name: 'title',
      type: 'string',
    },
    {
      title: 'Poster',
      name: 'poster',
      type: 'image',
    },
    {
      title: 'Directors',
      name: 'directors',
      type: 'array',
      of: [{type: 'string'}],
    },
  ],
}

Groups Example

import {AiOutlineHome as icon} from 'react-icons/ai'
import {F, G, P} from '@gearbox-built/sanity-schema-tool'

export const page = F.document({
  icon,
  name: 'page',
  groups: [G.define('content'), G.define('meta'), G.define('seo', {title: 'SEO'})],
  fields: [
    ...G.group('content', [F.title(), F.field('hero'), F.field('components')]),
    ...G.group('meta', [F.slug(), F.field('path')]),
    ...G.group('seo', [F.seo()]),
  ],
  preview: P.titleImage(),
})

export const page = {
  icon
  title: 'Page',
  name: 'page',
  type: 'document',
  groups: [
    { name: 'content', title: 'Content' },
    { name: 'meta', title: 'Meta' },
    { name: 'seo', title: 'SEO' },
  ],
  fields: [
    {
      title: 'Title',
      name: 'title',
      type: 'string',
      group: 'content',
    },
    {
      title: 'Hero',
      name: 'hero',
      type: 'hero'
      group: 'content',
    },
    {
      title: 'Components',
      name: 'components',
      type: 'components',
      group: 'content',
    },
    {
      title: 'Slug',
      name: 'slug',
      type: 'slug',
      group: 'meta',
    },
    {
      title: 'Path',
      name: 'path',
      type: 'path',
      group: 'meta',
    },
    {
      title: 'SEO',
      name: 'seo',
      type: 'seo',
      group: 'seo',
    }
  ],
  preview: {
    select: {
      title: 'title',
      media: 'image',
    }
  }
}

Customization

Use the provided withConfig function to configure the Schema Tool to set meaningful defaults for your project.

// schemaTool.ts
import {F as _F, withConfig} from '@gearbox-built/sanity-schema-tool'

const {F, FS, G, P, V} = withConfig({
  image: {
    components: {input: ImageInput},
    fields: [_F.string({name: 'lqip', hidden: true})],
  },
  slug: {
    required: false,
  },
})

export {F, FS, G, P, V}
export type * from '@gearbox-built/sanity-schema-tool'

If you don't want to rename your F import because of reasons, you can just export the configured Schema Tool with types in this manner:

// schemaTool/config.ts
import {F, withConfig} from '@gearbox-built/sanity-schema-tool'

export default withConfig({
  image: {
    components: {input: ImageInput},
    fields: [F.string({name: 'lqip', hidden: true})],
  },
  slug: {
    required: false,
  },
})

// schemaTool/index.ts
import schemaToolConfig from './config'
export type * from '@gearbox-built/sanity-schema-tool'

const {F, FS, G, P, V} = schemaToolConfig
export {F, FS, G, P, V}

Usage

import { F } from `@/schemaTool` // or your path `../../schemaTool`

export const movie = F.document({
  name: 'movie',
  fields: [
    F.title(),
    F.image({ name: 'poster' }),
    F.array({ name: 'directors', of: [F.string()]})
  ]
})

Extension

The withConfig allows for the definition of custom types by passing an object with the keys of F, FS, G, P, or V as the second parameter.

import {F, withConfig, StringField, FieldReturn} from '@gearbox-built/sanity-schema-tool'

export const customTypes = {
  F: {
    dropdown: (list: string[], props: StringField): FieldReturn =>
      F.string({options: {list, layout: 'dropdown'}}, props),
  },
}

export default withConfig({}, customTypes)

Usage

You can then use your custom types in your schema:

import {F} from `@/schemaTool` // or your path `../../schemaTool`

export const movie = F.document({
  name: 'movie',
  fields: [
    F.title(),
    F.image({ name: 'poster' }),
    F.array({ name: 'directors', of: [F.string()]}),
    F.dropdown(['a', 'b', 'c'], { name: 'type' }),
  ]
})

Example Config

import {F as _F, withConfig, StringField, FieldReturn} from '@gearbox-built/sanity-schema-tool'

export const customTypes = {
  F: {
    dropdown: (list: string[], props: StringField): FieldReturn =>
      _F.string({options: {list, layout: 'dropdown'}}, props),
  },
}

const {F, FS, G, P, V} = withConfig(
  {
    image: {
      components: {input: ImageInput},
      fields: [_F.string({name: 'lqip', hidden: true})],
    },
    slug: {
      required: false,
    },
  },
  customTypes
)

export {F, FS, G, P, V}
export type * from '@gearbox-built/sanity-schema-tool'
