A New UI Localization Pattern

@ SPS Commerce

 

(Spelled localisation when rendered in the en-UK locale)

 

How is localization different from internationalization?

What are locales compared to languages?

 

internationalization (i18n)

the process of developing products in such a way that they can be localized for languages and cultures easily.

 

Sometimes referred to as globalization.

the process of adapting applications and text to enable their usability in a particular cultural or linguistic market (locale).

localization      (l10n)

General

Specific

Language     vs

English (en) is a language

American English (en-US) is a locale

Spanish (es) is a language

Chinese (zh) is a language

Spain Spanish (es-ES) is a locale

Chinese Traditional (zh-CN) is a locale

Chinese Simplified (zh-TW) is a locale

British English (en-GB) is a locale

Locale

What locales does SPS Commerce support (other than the en-US default)?

Spanish (Spain)

French (Canada)

French (France)

Chinese (Traditional)

Chinese (Simplified)

Why a new pattern? What was wrong with the old one?

Non english locale translations were loaded over the network instead of bundled with UI applications at deploy.

 

It was possible to push code before your translations were ready, resulting in blank interfaces for end users!

 

Lack of ability to perform a diff between phrase (prod), local changes, and github.

 

No CI integration to check for error states.

When you hear "UI Localization at SPS Commerce" think:

phrase-cli

+ 

Design System

i18n package

+ 

First you need a repo!

First we generate a new project from DS:

    https://github.com/SPSCommerce/ds-react-seed/generate

 

Let's assume we generated a repo called:

    test-localization

 

Then we clone our new repo locally:

   gh repo clone SPSCommerce/test-localization

We need a Phrase Account, Project & (Oauth) access token

Once you have a Phrase account in our org, generate a token at:

    https://app.phrase.com/settings/oauth_access_tokens

 

#dev-localization

Ask for an invite to our Phrase organization.

Ask for a new Phrase project id (give us your project name).

 

 

 

Initialize your repo w/ the SPS Commerce phrase-cli

pnpm exec @spscommerce/phrase-cli init -p PROJECT_ID

hint:

pnpm exec is like npx which just executes a command from a given package, in this case @spscommerce/phrase-cli

This is going to create a few translation files in /public/locales in your repo which you should commit as they will change over time.

Install the SPS Commerce i18n dependencies

Install the SPS i18n (internationalization) package:

    pnpm install @spscommerce/i18n

 

Enable the i18n package

Enable localization in your UI application.

import { localize } from "@spscommerce/i18n";

localize({
    debug: false,
    keySeparator: false,
    translationPath: `${process.env.PUBLIC_URL}/locales/{{lng}}/{{ns}}.json`,
});

(t)ranslate w/ the i18n package

Import the hook

import { useSpsLanguage } from "@spscommerce/i18n";

const { t } = useSpsLanguage();

Use it in your component to get 't' (a translation function)

<p>{t("cp.appPlatform.sessionTime", { 
  minutes: expiresInMinutes 
})}</p>

and translate using the t function!

Placing the translation in /public/locales/en-US/translation.json

{ "cp.appPlatform.sessionTime": "Your session will expire in {{minutes}} minutes." }

Finally, add an Azure DevOps check to keep us honest

Place Phrase access

key in ADO secrets

Edits directly in Phrase

If someone makes edits in Phrase (Product Team for example) we will detect that the code we have in the repo differs from Phrase.

 

We will ask you to resolve the problems and give commands to execute before you will be able to push.
