  • react-i18next

    Internationalization for react done right. Using the i18next i18n ecosystem.

    Project mention: Pains and solutions in localization for the web | | 2023-12-13

    In a recent project I've been using react-i18next so I'll use its syntax for the examples, but pretty much every library works similarly.

  • i18next

    i18next: learn once - translate everywhere

    Project mention: Top 20 Frontend Interview Questions With Answers | | 2024-02-03

    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.

  • fluent

    Fluent — planning, spec and documentation (by projectfluent)

    Project mention: Use YouTube to improve your English pronunciation | | 2023-10-30

    Tried BoldVoice right now and almost immediately hit a bit of awkwardness: “Tomorrow, we’ll work on Practice your consonant skills”. Usually I wouldn’t complain about this sort of thing, but in a language learning app it seems unfortunate. (Mozilla’s Project Fluent[1] was built to handle these situations in a localization setting, but you can probably get away with something much simpler.)


  • fluent.js

    JavaScript implementation of Project Fluent

    Project mention: Internationalize TypeScript app | /r/node | 2023-04-26

    Want to quick internationalize your app? You can use com.hydroper.ftl from NPM, which uses Fluent. Should work for browser (if you use Webpack targetting "browser") and NodeJS. It uses Intl from ECMA-402 and @fluent/bundle.

    Project mention: Typed translations in Angular | | 2023-11-08

    The situation is partly saved by the eslint plugin eslint-plugin-i18n-json, which checks the identity of the keys in json files, but it's also not enough for reliability.
