Payload features deep field-based localization support. Maintaining as many locales as you need is easy. All localization support is opt-in by default. To do so, follow the two steps below.
Add the localization property to your Payload config to enable localization project-wide. You'll need to provide a list of all locales that you'd like to support as well as set a few other options.
Example Payload config set up for localization:
Here is a brief explanation of each of the options available within the localization property:
locales
Array-based list of all locales that you would like to support. These strings do not need to be in any specific format. It's up to you to define how to represent your locales. Common patterns are to use two-letter ISO 639 language codes or four-letter language and country codes (ISO 3166‑1) such as en-US, en-UK, es-MX, etc.
defaultLocale
Required string that matches one of the locales from the array provided. By default, if no locale is specified, documents will be returned in this locale.
fallback
Boolean enabling "fallback" locale functionality. If a document is requested in a locale, but a field does not have a localized value corresponding to the requested locale, then if this property is enabled, the document will automatically fall back to the fallback locale value. If this property is not enabled, the value will not be populated.
Payload localization works on a field level—not a document level. In addition to configuring the base Payload config to support localization, you need to specify each field that you would like to localize.
Here is an example of how to enable localization for a field:
With the above configuration, the title field will now be saved in the database as an object of all locales instead of a single string.
All field types with a name property support the localized property—even the more complex field types like arrays and blocks.
When retrieving documents, you can specify which locale you'd like to receive as well as which fallback locale should be used.
REST API locale functionality relies on URL query parameters.
?locale=
Specify your desired locale by providing the locale query parameter directly in the endpoint URL.
?fallback-locale=
Specify fallback locale to be used by providing the fallback-locale query parameter. This can be provided as either a valid locale as provided to your base Payload config, or 'null', 'false', or 'none' to disable falling back.
Example:
In the GraphQL API, you can specify locale and fallbackLocale args to all relevant queries and mutations.
The locale arg will only accept valid locales, but locales will be formatted automatically as valid GraphQL enum values (dashes or special characters will be converted to underscores, spaces will be removed, etc.). If you are curious to see how locales are auto-formatted, you can use the GraphQL playground.
The fallbackLocale arg will accept valid locales as well as none to disable falling back.
Example:
You can specify locale as well as fallbackLocale within the Local API as well as properties on the options argument. The locale property will accept any valid locale, and the fallbackLocale property will accept any valid locale as well as 'null', 'false', false, and 'none'.
