Javascript Programming Tutorials, Guides & Best Practices

Create 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 />,
  },
];

Use IP detection (via backend or service like IPinfo):

if (userCountry === 'EG') {
  showEGPPrices();
} else {
  showUSDPrices();
}

In this tutorial, you'll learn how to implement i18n in a scalable way using i18next, the most popular library for internationalizing React apps.

If you don’t have a project yet, initialize a new one:

With Webpack Module Federation, you can load the Vue-based analytics micro-frontend into the React host — all without bundling it directly.

We’ll build two apps:

Zustand supports middleware for logging, persisting state, and more. For example, integrating with Redux DevTools:

import create from 'zustand';
import { devtools } from 'zustand/middleware';

const useStore = create(devtools((set) => ({
  count: 0,
  increase: () => set((state) => ({ count: state.count + 1 })),
})));
