i18n-node VS i18next

One great tool for inclusion is the i18n package helping us develop multi language apps with minimum effort.

If you plan to create a multilingual version of your app, you should use one of the Node.js internationalization libraries available, for example on Openbase. This article will cover the i18n-node as an example. You may choose another library according to your preferences. They do implement localization functionality pretty much in the same way.

Great Work ! Kudos 👍. Just a suggestion that as you are building something which has a worldwide audience scope you might need to add language support which might not be very difficult with you current tech stack. You can use i18n package .

You have to maintain translation keys. Lookup i18n. This is a js lib for example: https://www.npmjs.com/package/i18n

Or the developer can save everyone the effort and just import an NPM package for it: https://www.npmjs.com/package/i18n

Take a look at the industry standard i18n

Have you considered why this would be used rather than a internationalization package such as https://www.npmjs.com/package/i18n? Also adding the ability for language translations to the snippets would be awesome 🙂

🌍 i18next Documentation

i18next is a popular internationalization library for JavaScript applications. It provides a robust framework for managing translations, formatting dates, numbers, and handling pluralization. i18next supports multiple backends for storing translations, making it versatile and adaptable to various project requirements.

For this article, we'll leverage the 'Simple CRM' project from our previous list of projects. We'll integrate and utilize the i18n library to internationalize our application.

When starting a new project with Next.js these days, next-intl and zod are my go to libraries for internationalization and schema validation, respectively. Of course, when using zod for client-facing validations I would like to translate potential error messages. The package zod-i18n can be used to achieve this for i18next, a popular alternative internationalization library. This means that by using this library as starting point one can quickly achieve zod translation with next-intl.

The best way to implement internationalization is to use an internationalization framework library, such as i18next. With this kind of library, you can easily handle translations and automatically display your frontend labels in the user's language. The frontend application also needs to be flexible and easily configurable so that its layout can change accordingly, reading from left to right or right to left. CSS allows this with the rtl and ltr CSS direction property.

For reference, I am using i18next for providing translations, which is configured to use the english message string as a key for the translations and fallback to it if no translation is found in the chosen language. I also use the official svelte-i18next integration. It wraps the i18next object in a Svelte store and, among other things, provides reactivity when the language is changed.

// app/components/BuiltInFormatsDemo.tsx 'use client'; import React from 'react'; import {useTranslation} from '../i18n/client'; import type {LocaleTypes} from '../i18n/settings'; import {useParams} from 'next/navigation'; const BuiltInFormatsDemo = () => { let locale = useParams()?.locale as LocaleTypes; const {t} = useTranslation(locale, 'built-in-demo'); return (

{/* "number": "Number: {{val, number}}", */} {t('number', { val: 123456789.0123, })} p>

{/* "currency": "Currency: {{val, currency}}", */} {t('currency', { val: 123456789.0123, style: 'currency', currency: 'USD', })} p>

{/* "dateTime": "Date/Time: {{val, datetime}}", */} {t('dateTime', { val: new Date(1234567890123), formatParams: { val: { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric', }, }, })} p>

{/* "relativeTime": "Relative Time: {{val, relativetime}}", */} {t('relativeTime', { val: 12, style: 'long', })} p>

{/* "list": "List: {{val, list}}", */} {t('list', { // https://www.i18next.com/translation-function/objects-and-arrays#objects // Check the link for more details on `returnObjects` val: t('weekdays', {returnObjects: true}), })} p> div> ); }; export default BuiltInFormatsDemo;

As our world becomes increasingly interconnected, the development of web applications that cater to a global audience takes precedence among developers. If you're a TypeScript developer, you're likely acquainted with the advantages of static typing and the assurance it provides in your codebase. When it comes to internationalization (i18n) and localization (l10n), maintaining the same level of type safety becomes crucial. This is precisely where i18next, an influential i18n framework, enters the picture.

In this article, we will go over how to perform internationalisation in our react app using the i18next framework. I18next is an internationalisation framework written in JavaScript. It comes with everything you need to localise your web, desktop or mobile product such as user language detection, loading and caching translations, and file conversion etc More features can be found in their documentation.
