Setup multilingual and multi-regional storefronts with URL paths

• You have a working Hydrogen project. For more information, refer to the getting started guide.
• You have setup the regions and languages you chose for your store with Shopify Markets.
• You're familiar with using the Storefront API with Shopify Markets.

Create a utility function that reads the requested host and directory path which return the right Locale object using the Storefronts API's supported language and country codes.

The following is an example utility function with the following locales en_CA, fr_CA and en_US.

The Locale object returned should resemble the following example, which is using the Storefont API's supported language and country codes.

Using Remix's optional segments, add ($locale) in front of your routes.

This ensures that routes such as /products/123 and /fr/products/123 matches to the same product route file in Remix, so that the correct page is rendered.

The following is an example of files and folders before file rename with ($locale):

After renaming the routes with ($locale), your new file structure should look like the following example:

At this point, you should see your pages render when you make requests to /fr/ URL paths.

In your server.js, update i18n to the result of the utility function when creating the Hydrogen storefront client.

By doing this, you now have the locale available throughout the app for every storefront query.

To support international pricing and languages in Storefront API, you need to pass the $country and $language with an @inContext directive within any requests.

Update your GraphQL queries with inContext directives to include $country and $language. Hydrogen automatically injects these parameters.

For example, this is a Storefront API query that returns featured collections from the homepage. This updates it to include the inContext directive.

You don't need to manually provide query variables for country and language. You can make the query with storefront.query in the data loader and see the right language and currencies for each request.

Hydrogen automatically injects the locale parameters to storefront.query based on what was defined in i18n when you created the client.

For example, if a request came from hydrogen.fr, then the country CA and language FR are used as defined in the utilities function.

The Storefront API returns the correct currency and language if the store was set up in the Shopify admin.

If you want to override the locale determined by your utility option, then you can supply the query variables to the storefront.query:

A request to /this-route-does-not-exist should return a 404 not found page.

To achieve this, create a $.(tsx|jsx) file in the /app/routes/` folder. This Remix splat route will handle all the non-matching routes.

In the /app/routes/index.jsx, set up handling of invalid URL parameters localization. For example, any request with lang parameter au when you don't handle this language, should return a 404.

Create a utility function that adds the locale path prefix to any URL path. For example, if the path is /products and the buyer prefers the locale fr_CA, then the utility function converts it to /fr/products.

Use this utility function anywhere you need to define a localized path. For example, form actions should have the localized path.

Create a <Link /> wrapper component that adds the locale path prefix. You can create this file in any components folder. In the case of the Hydrogen demo store, components folder was created for base components.

If you have multilingual handles for your product or collection, for example, products/スノーボード, make sure to encode url when making redirects.
