Beginner's Guide: Setting up React & Angular for Building Web Applications

A basic setup for getting started with React. Follow these steps:

Step 1: Install Node.js

React requires Node.js, so make sure you have it installed on your machine. You can download it from the official Node.js website: https://nodejs.org

Step 2: Create a New React Project

Open your terminal or command prompt and navigate to the directory where you want to create your project. Run the following command to create a new React project:

```

npx create-react-app my-react-app

```

This will create a new directory called `my-react-app` with the basic setup for a React project.

Step 3: Navigate to the Project Directory

Go to the project directory by running the following command:

```

cd my-react-app

```

Step 4: Start the Development Server

To start the development server and see your React app in the browser, run the following command:

```

npm start

```

This will compile your React code and launch a local development server. You can access your app by opening your browser and navigating to `http://localhost:3000`.

Step 5: Explore the Project Structure

Inside the `my-react-app` directory, you'll find the following folders and files:

- `src`: This folder contains the source code of your React app. You'll spend most of your time here.

- `public`: This folder contains the HTML file (`index.html`) where your React app is mounted.

- `package.json`: This file holds the project configuration and lists the dependencies.

Step 6: Edit the React App

Open the project in your favorite code editor and navigate to the `src` folder. You'll find the `App.js` file, which is the main component of your React app. You can edit this file to modify your app's content and structure.

Step 7: Start Building Your React App

You're now ready to start building your React app! You can create new components, import libraries, and add functionality to your app by editing the files in the `src` directory.

Remember to refer to the official React documentation (https://reactjs.org/) for more detailed information on using React.

That's it! You have set up a basic React project and are ready to start coding. Happy Reacting!

Here's a step-by-step guide to setting up Angular for beginners:

Step 1: Install Node.js

Angular requires Node.js and npm (Node Package Manager). Download and install Node.js from the official website: https://nodejs.org

Step 2: Install Angular CLI

Angular CLI (Command Line Interface) is a powerful tool for scaffolding and managing Angular projects. Open your terminal or command prompt and run the following command to install Angular CLI globally:

```

npm install -g @angular/cli

```

Step 3: Create a New Angular Project

Navigate to the directory where you want to create your Angular project. Run the following command to create a new project:

```

ng new my-angular-app

```

This will generate a new directory called `my-angular-app` with the basic setup for an Angular project.

Step 4: Navigate to the Project Directory

Go to the project directory by running the following command:

```

cd my-angular-app

```

Step 5: Start the Development Server

To start the development server and see your Angular app in the browser, run the following command:

```

ng serve

```

This command compiles your Angular code and launches a local development server. You can access your app by opening your browser and navigating to `http://localhost:4200`.

Step 6: Explore the Project Structure

Inside the `my-angular-app` directory, you'll find the following folders and files:

- `src`: This folder contains the source code of your Angular app. You'll spend most of your time here.

- `angular.json`: This file holds the project configuration, including build settings and dependencies.

- `package.json`: This file lists the project dependencies and scripts.

Step 7: Edit the Angular App

Open the project in your favorite code editor and navigate to the `src` folder. You'll find the `app` subfolder, which contains the main components and files of your Angular app. You can edit these files to modify your app's content and structure.

Step 8: Start Building Your Angular App

You're now ready to start building your Angular app! You can create new components, services, and modules, and add functionality to your app by editing the files in the `src` directory.

Remember to refer to the official Angular documentation (https://angular.io/) for detailed information on using Angular and its features.

That's it! You have set up a basic Angular project and are ready to start coding. Enjoy building with Angular!

Story of the Nilavanti Granth

A story about the Nilavanti Granth: एक समय की बात है, भारत के दिल में एक रहस्यमयी पुस्तक थी जिसे निलावंती ग्रंथ कहा जाता था। यह पुस्तक संस्कृत में एक ऋषि द्वारा लिखी गई थी। यह भारत की सबसे रहस्यमयी और चमत्कारी पुस्तकों में से एक मानी जाती थी। निलावंती ग्रंथ की कहानी निलावंती नामक एक महिला के साथ शुरू होती है, जिसे जादुई क्षमताओं का होना कहा जाता था। कहा जाता था कि उसे सभी जीवित प्राणियों की भाषा समझने की क्षमता थी। इसी अद्वितीय क्षमता के कारण निलावंती ग्रंथ इतना विशेष था। निलावंती उत्तर प्रदेश के एक छोटे से गांव में पैदा हुई थीं। जब वह सिर्फ पांच साल की थी, उसकी मां का निधन हो गया, तब उसके पिता ने उसे लेकर दूसरे गांव में चले गए। निलावंती ने अपने पिता से आयुर्वेद सीखा और उसे पौधों, जानवरों, और पक्षियों की भाषा समझने की अद्वितीय क्षमता भी थी। निलावंती जब बड़ी हुई, तो उसे सपने आने लगे जिसमें भूत-प्रेत उसे पृथ्वी के नीचे छिपे हुए खजानों के बारे में बताते थे। इन खजानों के बारे में जानने के बावजूद, निलावंती, एक सच्ची व्यक्ति होने के नाते, कभी उन्हें खोदकर नहीं निकाली। बजाय इसके, उसने भ...

वीर्य कैसे बनता है

वीर्य शरीर की बहुत मूल्यवान् धातु है । भोजन से वीर्य बनने की प्रक्रिया बड़ी लम्बी है | श्री सुश्रुताचार्य ने लिखा है : रसाद्रक्तं ततो मांसं मांसान्मेदः प्रजायते | मेदस्यास्थिः ततो मज्जा मज्जायाः शुक्रसंभवः ॥ जो भोजन पचता है , उसका पहले रस बनता है । पाँच दिन तक उसका पाचन होकर रक्त बनता है । पाँच दिन बाद रक्त में से मांस , उसमें से 5-5 दिन के अंतर से मेद , मेद से हड्डी , हड्डी से मज्जा और मज्जा से अंत में वीर्य बनता है । स्त्री में जो यह धातु बनती है उसे ‘ रज ‘ कहते हैं । वीर्य किस प्रकार छः सात मंजिलों से गुजरकर अपना यह अंतिम रूप धारण करता है , यह सुश्रुत के इस कथन से ज्ञात हो जाता है । कहते हैं कि इस प्रकार वीर्य बनने में करीब 30 दिन व 4 घण्टे लग जाते हैं । वैज्ञनिक लोग कहते हैं कि 32 किलोग्राम भोजन से 700 ग्राम रक्त बनता है और 700 ग्राम रक्त से लगभग 20 ग्राम वीर्य बनता है । आकर्षक व्यक्तित्व का कारण इस वीर्य के संयम से शरीर में एक अदभुत आकर्षक शक्ति उत्पन्न होती है जिसे प्राचीन वैद्य धन्वंतरि ने ‘ ओज ‘ नाम दिया है । यही ओज मनुष्य को अपने परम – लाभ ‘ आत्मदर्शन ‘ कराने में सहायक बनता है ...

वीर्यरक्षा के उपाय

सादा रहन – सहन बनायें काफी लोगों को यह भ्रम है कि जीवन तड़क – भड़कवाला बनाने से वे समाज में विशेष माने जाते हैं । वस्तुतः ऐसी बात नहीं है । इससे तो केवल अपने अहंकार का ही प्रदर्शन होता है । लाल रंग के भड़कीले एवं रेशमी कपड़े नहीं पहनो । तेल – फुलेल और भाँति – भाँति के इत्रों का प्रयोग करने से बचो । जीवन में जितनी तड़क – भड़क बढ़ेगी , इन्द्रियाँ उतनी चंचल हो उठेंगी , फिर वीर्यरक्षा तो दूर की बात है । इतिहास पर भी हम दृष्टि डालें तो महापुरुष हमें ऐसे ही मिलेंगे , जिनका जीवन प्रारंभ से ही सादगीपूर्ण था । सादा रहन – सहन तो बडप्पन का द्योतक है । दूसरों को देख कर उनकी अप्राकृतिक व अधिक आवश्यकताओंवाली जीवन शैली का अनुसरण नहीं करो । उपयुक्त आहार ईरान के बादशाह बहमन ने एक श्रेष्ठ वैद्य से पूछा : “ दिन में मनुष्य को कितना खाना चाहिए ? ” “ सौ दिराम ( अर्थात् 31 तोला ) | “ वैद्य बोला | “ इतने से क्या होगा ? ” बादशाह ने फिर पूछा । वैद्य ने कहा : “ शरीर के पोषण के लिये इससे अधिक नहीं चाहिए | इससे अधिक जो कुछ खाया जाता है , वह केवल बोझा ढोना है और आयुष्य खोना है । ” लोग स्वाद के लिये अपने पेट क...
