This is the Sanity Studio v3 version of sanity-plugin-internationalized-array.
For the v2 version, please refer to the v2-branch.
A plugin to register array fields with a custom input component to store field values in multiple languages, queryable by using the language ID as an array _key
.
npm install --save sanity-plugin-internationalized-array
or
yarn add sanity-plugin-internationalized-array
Add it as a plugin in sanity.config.ts (or .js):
import {defineConfig} from 'sanity'
import {internationalizedArray} from 'sanity-plugin-internationalized-array'
export const defineConfig({
// ...
plugins: [
internationalizedArray({
languages: [
{id: 'en', title: 'English'},
{id: 'fr', title: 'French'}
],
defaultLanguages: ['en'],
fieldTypes: ['string'],
})
]
})
This will register two new fields to the schema, based on the settings passed into fieldTypes
:
-
internationalizedArrayString
an array field of: -
internationalizedArrayStringValue
an object field, with a singlestring
field inside calledvalue
The above config will also create an empty array item in new documents for each language in defaultLanguages
. This is configured globally for all internationalized array fields.
You can pass in more registered schema-type names to generate more internationalized arrays. Use them in your schema like this:
// For example, in postType.ts
fields: [
defineField({
name: 'greeting',
type: 'internationalizedArrayString',
}),
]
Languages must be an array of objects with an id
and title
.
languages: [
{id: 'en', title: 'English'},
{id: 'fr', title: 'French'}
],
Or an asynchronous function that returns an array of objects with an id
and title
.
languages: async () => {
const response = await fetch('https://example.com/languages')
return response.json()
}
The async function contains a configured Sanity Client in the first parameter, allowing you to store Language options as documents. Your query should return an array of objects with an id
and title
.
languages: async (client) => {
const response = await client.fetch(`*[_type == "language"]{ id, title }`)
return response
},
Additionally, you can "pick" fields from a document, to pass into the query. For example, if you have a concept of "Markets" where only certain language fields are required in certain markets.
In this example, each language document has an array of strings called markets
to declare where that language can be used. And the document being authored has a single market
field.
select: {
market: 'market'
},
languages: async (client, {market = ``}) => {
const response = await client.fetch(
`*[_type == "language" && $market in markets]{ id, title }`,
{market}
)
return response
},
The "Add translation" buttons can be positioned in one or multiple locations by configuring buttonLocations
:
-
field
(default) Below the internationalized array field -
unstable__fieldAction
Inside a Field Action (currently unstable) -
document
Above the document fields, these buttons will add a new language item to every internationalized array field that can be found at the root of the document. Nested internationalized arrays are not yet supported.
The "Add all languages" button can be hidden with buttonAddAll
.
import {defineConfig} from 'sanity'
import {internationalizedArray} from 'sanity-plugin-internationalized-array'
export const defineConfig({
// ...
plugins: [
internationalizedArray({
// ...other config
buttonLocations: ['field', 'unstable__fieldAction', 'document'], // default ['field']
buttonAddAll: false // default true
})
]
})
For more control over the value
field, you can pass a schema definition into the fieldTypes
array.
import {defineConfig} from 'sanity'
import {internationalizedArray} from 'sanity-plugin-internationalized-array'
export const defineConfig({
// ...
plugins: [
internationalizedArray({
languages: [
{id: 'en', title: 'English'},
{id: 'fr', title: 'French'}
],
fieldTypes: [
defineField({
name: 'featuredProduct',
type: 'reference',
to: [{type: 'product'}]
hidden: (({document}) => !document?.title)
})
],
})
]
})
This would also create two new fields in your schema.
-
internationalizedArrayFeaturedProduct
an array field of: -
internationalizedArrayFeaturedProductValue
an object field, with a singlestring
field inside calledvalue
Note that the name
key in the field gets rewritten to value
and is instead used to name the object field.
Due to how fields are created, you cannot use anonymous objects in the fieldTypes
array. You must register the object type in your Studio's schema as an "alias type".
// ./schemas/seoType.ts
import {defineField} from 'sanity'
export const seoType = defineField({
name: 'seo',
title: 'SEO',
type: 'object',
fields: [
defineField({name: 'title', type: 'string'}),
defineField({name: 'description', type: 'string'}),
],
})
Then in your plugin configuration settings, add the name of your alias type to the fieldTypes
setting.
internationalizedArray({
languages: [
//...languages
],
fieldTypes: ['seo'],
})
Lastly, add the field to your schema.
// ./schemas/post.ts
import {defineField, defineType} from 'sanity'
export default defineType({
name: 'post',
title: 'Post',
type: 'document',
fields: [
defineField({
name: 'seo',
type: 'internationalizedArraySeo',
}),
],
})
If you have many languages and authors that predominately write in only a few, @sanity/language-filter can be used to reduce the number of language fields shown in the document form.
Configure both plugins in your sanity.config.ts file:
// ./sanity.config.ts
import {defineConfig, isKeySegment} from 'sanity'
import {languageFilter} from '@sanity/language-filter'
export default defineConfig({
// ... other config
plugins: [
// ... other plugins
languageFilter({
// Use the same languages as the internationalized array plugin
supportedLanguages: SUPPORTED_LANGUAGES,
defaultLanguages: [],
documentTypes: ['post'],
filterField: (enclosingType, member, selectedLanguageIds) => {
// Filter internationalized arrays
if (
enclosingType.jsonType === 'object' &&
enclosingType.name.startsWith('internationalizedArray') &&
'kind' in member
) {
// Get last two segments of the field's path
const pathEnd = member.field.path.slice(-2)
// If the second-last segment is a _key, and the last segment is `value`,
// It's an internationalized array value
// And the array _key is the language of the field
const language =
pathEnd[1] === 'value' && isKeySegment(pathEnd[0])
? pathEnd[0]._key
: null
return language ? selectedLanguageIds.includes(language) : false
}
// Filter internationalized objects if you have them
// `localeString` must be registered as a custom schema type
if (
enclosingType.jsonType === 'object' &&
enclosingType.name.startsWith('locale')
) {
return selectedLanguageIds.includes(member.name)
}
return true
},
}),
],
})
The custom input contains buttons which will add new array items with the language as the _key
value. Data returned from this array will look like this:
"greeting": [
{ "_key": "en", "value": "hello" },
{ "_key": "fr", "value": "bonjour" },
]
Using GROQ filters you can query for a specific language key like so:
*[_type == "person"] {
"greeting": greeting[_key == "en"][0].value
}
See the migration script inside ./migrations/transformObjectToArray.ts
of this Repo.
Follow the instructions inside the script and set the _type
and field name you wish to target.
Please take a backup first!
The most popular way to store field-level translated content is in an object using the method prescribed in @sanity/language-filter. This works well and creates tidy object structures, but also creates a unique field path for every unique field name, multiplied by the number of languages in your dataset.
For most people, this won't become an issue. On a very large dataset with a lot of languages, the Attribute Limit can become a concern. This plugin's arrays will use fewer attributes than an object once you have more than three languages.
The same content as above, plus a third language, structured as an object
of string
fields looks like this:
"greeting" {
"en": "hello",
"fr": "bonjour",
"es": "hola"
}
Which creates four unique query paths, one for the object and one for each language.
greeting
greeting.en
greeting.fr
greeting.es
Every language you add to every object that uses this structure will add to the number of unique query paths.
The array created by this plugin creates four query paths by default, but is not affected by the number of languages:
greeting
greeting[]
greeting[]._key
greeting[].value
By using this plugin you can safely extend the number of languages without adding any additional query paths.
