Create routes.js:
routes.js
import Home from './pages/Home'; import About from './pages/About'; export const routes = (t) => [ { path: `/${t('routes.home')}`, element: <Home />, }, { path: `/${t('routes.about')}`, element: <About />, }, ];
In 2025, more users are accessing the web from non-English regions than ever before. Some reasons to globalize your React app:
import React from 'react'; import { useTranslation } from 'react-i18next'; const Home = () => { const { t, i18n } = useTranslation(); const changeLanguage = (lng) => { i18n.changeLanguage(lng); }; const today = new Date(); const price = 199.99; return ( <div className="p-4"> <h1>{t('welcome')}</h1> <div className="mt-4"> <strong>{t('language')}:</strong> <button onClick={() => changeLanguage('en')} className="ml-2">EN</button> <button onClick={() => changeLanguage('fr')} className="ml-2">FR</button> </div> <p>{t('date_example', { date: today })}</p> <p>{t('price_example', { price })}</p> </div> ); }; export default Home;
Install i18next-format plugin (optional):
i18next-format
Then start the host app (React):
cd app-shell npx webpack serve
import create from 'zustand'; const useStore = create((set) => ({ count: 0, increase: () => set((state) => ({ count: state.count + 1 })), decrease: () => set((state) => ({ count: state.count - 1 })), }));
import React from 'react'; import useStore from './store'; function Counter() { const { count, increase, decrease } = useStore(); return ( <div> <h1>{count}</h1> <button onClick={increase}>Increase</button> <button onClick={decrease}>Decrease</button> </div> ); } export default Counter;
const value = useMemo(() => ({ user, setUser }), [user]);
const increment = useCallback(() => setCount(c => c + 1), []);
This should now work without any errors.

In this tutorial, you’ll learn how to create a web application that performs real-time object detection using your webcam. By combining TensorFlow.js—Google’s library for machine learning in JavaScript—with p5.js for creative coding and drawing, you can build an interactive app that detects objects on the fly.
This guide will walk you through setting up your development environment, loading a pre-trained model, capturing video input, and overlaying detection results on the video feed.
Tauri leverages web technologies to build native desktop applications while offloading critical operations to Rust. Paired with Svelte—a fast, compile-time JavaScript framework—you can create modern apps that are both visually appealing and highly performant. This tutorial will walk you through setting up your development environment, creating a Svelte project, integrating Tauri, and building your first desktop app.
