When will the green summons end? In Germany, the green turn began in the noughties. This means that now every fifth windmill
When will the green summons end? In Germany, the green turn began in the noughties. This means that now every fifth windmill in the country has been operating for 20-25 years. That is, they are about to work out their standard service life and are likely to be demolished. Horror for the real economy. Old windmills will be replaced with new ones. And these are new subsidies and another increase in electricity prices." However, the number of generators will remain the same. This cycle will now be endless: we demolish the old, build the new (this is the motivation to support the "green" so actively). 
"The energy transition has given the elites a clear conscience and at the same time a good profit margin,"
says Michael Vassiliadis, head of the Mining, Chemical and Energy Industrial Union(IG BCE). 🔥According to a Welt investigation in 2021, the environmental impact of the agenda brings a lot of profit to individuals. Representatives of environmental NGOs work closely with the Federal Government. How will this affect the industry? Automotive industry. The auto industry has lost 11,000 jobs over the past year. The outlook for the steel and electrical industries is daunting: Gesamtmetall, a lobbying group, predicts up to 300,000 job cuts over the next five years, accounting for almost 7% of total employment in these sectors. Chemistry and metallurgy. Industries are now producing 20% less than they did before 2022. RES cannot cover the required capacity. We are waiting for the German government to help the country end its energy and economic suicide. #Germany #Chemistry #Government 🇪🇺 Keep up with the latest Star Union News  🖥

Backend Development: Node.js & Express.js 1. What is Node.js? Node.js is a JavaScript runtime environment that allows JavaScript to run on the server-side. It is asynchronous, non-blocking, and event-driven, making it efficient for handling multiple requests. Why Use Node.js? Fast & Scalable – Runs on the V8 engine for high performance. Single Programming Language – Use JavaScript for both frontend and backend. Rich Ecosystem – Access thousands of packages via npm (Node Package Manager). 2. Setting Up Node.js 1. Install Node.js and npm from nodejs.org. 2. Verify installation by running: node -v  npm -v 3. Initialize a Node.js project inside a folder: mkdir backend-project && cd backend-project  npm init -y This creates a package.json file to manage dependencies. 3. What is Express.js? Express.js is a minimal and fast web framework for Node.js that simplifies building web servers and APIs. Why Use Express.js? Simple API – Easily create routes and middleware. Handles HTTP Requests – GET, POST, PUT, DELETE. Middleware Support – Add functionalities like authentication and logging. Installing Express.js npm install express 4. Creating a Basic Server with Express.js Import Express and create a web server. Define routes to handle requests (e.g., /home, /users). Start the server to listen on a specific port. 5. REST API with Express.js A REST API handles CRUD operations: GET → Fetch data POST → Add data PUT → Update data DELETE → Remove data You can create API endpoints to send and receive JSON data, making it easy to connect with frontend applications. 6. Middleware in Express.js Middleware functions execute before the request reaches the route handler. Built-in middleware → express.json() (parses JSON requests). Third-party middleware → cors, helmet, morgan (for security & logging). 7. Connecting Express.js with a Database Most applications need a database to store and manage data. Common choices include: MySQL / PostgreSQL → Relational databases (SQL). MongoDB → NoSQL database for flexible data storage. Connecting to MongoDB 1. Install Mongoose (MongoDB library for Node.js): npm install mongoose 2. Connect to MongoDB in your project and define models to store data efficiently. 8. Next Steps Once your backend is set up, the next steps are: Learn authentication (JWT, OAuth). Build RESTful APIs with proper error handling. Deploy your backend on AWS, Vercel, or Firebase.

Vuex is the official state management library for Vue.js, similar to Redux but designed specifically for Vue applications. Example: Simple Counter Using Vuex 1️⃣ Install Vuex npm install vuex 2️⃣ Create a Vuex Store import { createStore } from "vuex"; const store = createStore({ state: { count: 0 }, mutations: { increment(state) { state.count++; }, }, actions: { increment({ commit }) { commit("increment"); }, }, getters: { getCount: (state) => state.count, }, }); export default store; 3️⃣ Provide the Store in Vue App import { createApp } from "vue"; import App from "./App.vue"; import store from "./store"; const app = createApp(App); app.use(store); app.mount("#app"); 4️⃣ Use Vuex in a Component <template> <div> <h2>Count: {{ count }}</h2> <button @click="increment">Increment</button> </div> </template> <script> import { mapState, mapActions } from "vuex"; export default { computed: mapState(["count"]), methods: mapActions(["increment"]), }; </script> ✔ Pros: Integrated into Vue, simple to use. ❌ Cons: Not needed for small projects. 5. Which State Management Should You Use? Use Context API for small React projects that don't require complex state management. Use Redux for large-scale React applications where managing global state is crucial. Use Vuex if you're building a Vue.js application with shared state across components. 6. Next Steps Now that you understand state management, the next essential topic is Backend Development with Node.js & Express.js—learning how to build powerful server-side applications.

State Management: Redux, Vuex, and Context API Now that you’ve learned how to connect the frontend with a backend using APIs, the next crucial concept is state management. When building modern web applications, handling data across multiple components can become complex. This is where state management tools like Redux, Vuex, and Context API help. 1. What is State Management? State management refers to storing, updating, and sharing data between different parts of an application. Without proper state management, you might face issues like: Prop drilling → Passing data through multiple levels of components. Inconsistent UI updates → Different parts of the app showing outdated data. Difficult debugging → Hard to track state changes in large apps. State management solutions centralize the application's data, making it easier to manage and share across components. 2. Context API: Lightweight State Management in React The Context API is a built-in feature in React that allows prop drilling elimination by making data available globally. Example: Using Context API in React 1️⃣ Create a Context import React, { createContext, useState } from "react"; const ThemeContext = createContext(); export const ThemeProvider = ({ children }) => { const [theme, setTheme] = useState("light"); return ( <ThemeContext.Provider value={{ theme, setTheme }}> {children} </ThemeContext.Provider> ); }; export default ThemeContext; 2️⃣ Use Context in a Component import React, { useContext } from "react"; import ThemeContext from "./ThemeContext"; const ThemeSwitcher = () => { const { theme, setTheme } = useContext(ThemeContext); return ( <div> <h2>Current Theme: {theme}</h2> <button onClick={() => setTheme(theme === "light" ? "dark" : "light")}> Toggle Theme </button> </div> ); }; export default ThemeSwitcher; 3️⃣ Wrap Your App with the Provider import React from "react"; import ReactDOM from "react-dom"; import { ThemeProvider } from "./ThemeContext"; import ThemeSwitcher from "./ThemeSwitcher"; ReactDOM.render( <ThemeProvider> <ThemeSwitcher /> </ThemeProvider>, document.getElementById("root") ); ✔ Pros: Simple, built-in, and great for small apps. ❌ Cons: Not optimized for frequent state updates in large applications. 3. Redux: Scalable State Management for React and Other Frameworks Redux is a popular state management library that provides a centralized store for application data. It follows a strict data flow: 1️⃣ Actions → Describe changes (e.g., increment counter). 2️⃣ Reducers → Define how the state should change. 3️⃣ Store → Holds the global state. 4️⃣ Dispatch → Sends actions to update the state. Example: Simple Counter Using Redux 1️⃣ Install Redux and React-Redux npm install redux react-redux 2️⃣ Create a Redux Store import { createStore } from "redux"; const initialState = { count: 0 }; const counterReducer = (state = initialState, action) => { switch (action.type) { case "INCREMENT": return { count: state.count + 1 }; default: return state; } }; const store = createStore(counterReducer); export default store; 3️⃣ Provide the Store to the App import React from "react"; import ReactDOM from "react-dom"; import { Provider } from "react-redux"; import store from "./store"; import Counter from "./Counter"; ReactDOM.render( <Provider store={store}> <Counter /> </Provider>, document.getElementById("root") ); 4️⃣ Use Redux in a Component import React from "react"; import { useSelector, useDispatch } from "react-redux"; const Counter = () => { const count = useSelector((state) => state.count); const dispatch = useDispatch(); return ( <div> <h2>Count: {count}</h2> <button onClick={() => dispatch({ type: "INCREMENT" })}>Increment</button> </div> ); }; export default Counter; ✔ Pros: Great for large applications, scalable, predictable state. ❌ Cons: Boilerplate-heavy, requires additional setup. 4. Vuex: State Management for Vue.js

Connecting Frontend with Backend: APIs & Fetch/Axios Now that you’ve learned about frontend frameworks, it’s time to understand how they communicate with backend services to fetch and send data. This is done using APIs (Application Programming Interfaces) and tools like Fetch API and Axios. 1. What is an API? An API (Application Programming Interface) is a bridge between the frontend and backend that allows data exchange. APIs can be: RESTful APIs → Uses standard HTTP methods (GET, POST, PUT, DELETE). GraphQL APIs → Fetches specific data efficiently with queries. For example, when you visit a weather website, the frontend requests data from a weather API, and the backend responds with the current weather. 2. Fetch API: The Built-in JavaScript Method The Fetch API is a native JavaScript method used to make HTTP requests. It returns a Promise, which means it works asynchronously. Example: Fetching Data from an API fetch('https://jsonplaceholder.typicode.com/posts/1') .then(response => response.json()) .then(data => console.log(data)) .catch(error => console.error('Error:', error)); How It Works: fetch() makes a request to the given URL. .then(response => response.json()) converts the response into JSON format. .then(data => console.log(data)) logs the data to the console. .catch(error => console.error('Error:', error)) handles errors if the request fails. Making a POST Request Using Fetch To send data to a server, use the POST method and include the data in the request body. fetch('https://jsonplaceholder.typicode.com/posts', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ title: 'New Post', body: 'This is a new post', userId: 1 }) }) .then(response => response.json()) .then(data => console.log('Created:', data)) .catch(error => console.error('Error:', error)); The headers object specifies that we are sending JSON data. The body contains the JSON data we want to send. 3. Axios: A More Powerful Alternative to Fetch Axios is a third-party library that simplifies API calls. It provides: ✔ Shorter syntax ✔ Built-in error handling ✔ Automatic JSON parsing ✔ Support for request timeouts and canceling requests Installing Axios Before using Axios, install it in your project: npm install axios Or include it via CDN in HTML: <script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script> Example: Fetching Data Using Axios axios.get('https://jsonplaceholder.typicode.com/posts/1') .then(response => console.log(response.data)) .catch(error => console.error('Error:', error)); ✔ No need to manually convert the response to JSON. Making a POST Request Using Axios axios.post('https://jsonplaceholder.typicode.com/posts', { title: 'New Post', body: 'This is a new post', userId: 1 }) .then(response => console.log('Created:', response.data)) .catch(error => console.error('Error:', error)); ✔ Easier and cleaner compared to Fetch. 4. When to Use Fetch vs. Axios? Use Fetch if you want a lightweight, native JavaScript solution without extra dependencies. Use Axios if you need better error handling, concise syntax, and additional features like request cancellation. 5. Next Steps Now that you can connect the frontend with APIs, the next essential concept is State Management—handling and storing data efficiently in modern applications using Redux, Vuex, or Context API.

Modern Frontend Frameworks: React, Vue, or Angular Now that you’ve mastered JavaScript ES6+, it's time to explore frontend frameworks—powerful tools that simplify building dynamic web applications. 1. Why Use a Frontend Framework? Manually managing the DOM, UI updates, and application state with pure JavaScript is complex. Modern frontend frameworks like React, Vue, and Angular offer: Component-based architecture for reusability. Efficient rendering using Virtual DOM or optimized change detection. Faster development with built-in tools and libraries. 2. React: The Most Popular Library React, developed by Facebook (Meta), is widely used for building fast, scalable UI components. Key Features of React: Component-Based → Break UI into reusable pieces. Virtual DOM → Efficient updates improve performance. JSX (JavaScript XML) → Write HTML inside JavaScript. Hooks (useState, useEffect) → Manage state and lifecycle in functional components. React Example: A Simple Counter Component import React, { useState } from "react"; function Counter() {     const [count, setCount] = useState(0);         return (         <div>             <h1>Count: {count}</h1>             <button onClick={() => setCount(count + 1)}>Increment</button>         </div>     ); } export default Counter; React is ideal for single-page applications (SPAs), dashboards, and modern UI development. 3. Vue.js: The Beginner-Friendly Framework Vue is a lightweight and easy-to-learn framework known for its simplicity and flexibility. Key Features of Vue: Simple and fast → Easy to pick up with minimal JavaScript knowledge. Two-way data binding → Automatically syncs UI and state. Directives (v-if, v-for) → Simple syntax for dynamic UI updates. Vue Example: A Simple Counter Component <template>   <div>     <h1>Count: {{ count }}</h1>     <button @click="count++">Increment</button>   </div> </template> <script> export default {   data() {     return { count: 0 };   } }; </script> Vue is perfect for small-to-medium-sized applications, progressive enhancement, and fast prototyping. 4. Angular: The Enterprise-Level Framework Angular, built by Google, is a full-fledged framework designed for large-scale, enterprise-grade applications. Key Features of Angular: Built-in two-way data binding → Syncs data between UI and logic automatically. TypeScript-based → Ensures better code maintainability and error checking. Modular architecture → Suitable for complex, structured applications. Angular Example: A Simple Counter Component import { Component } from '@angular/core'; @Component({   selector: 'app-counter',   template:     <h1>Count: {{ count }}</h1>     <button (click)="increment()">Increment</button>   }) export class CounterComponent {   count = 0;     increment() {     this.count++;   } } Angular is best for large-scale apps, corporate applications, and teams that prefer TypeScript. 5. Which One Should You Choose? Choose React if you want a flexible, widely-used library with a huge job market. Choose Vue if you are a beginner and want a simple, easy-to-learn framework. Choose Angular if you're working on large enterprise applications and prefer TypeScript. 6. Next Steps Now that you've understood frontend frameworks, the next step is APIs & Fetch/Axios—how to connect your frontend with a backend to retrieve and send data.
