Components in React
Tags: beginners, react, learning, programming
Published: 2023-10-07 17:37:09

React is a popular framework used to build web applications. It is a JavaScript library developed by Facebook and has been used to create many applications such as Instagram, Netflix, Airbnb, and many more!

One of the biggest advantages to using React is the ability to create components. Components are blocks of code in which can be separated and reused. Having separate blocks of code allows us to easily determine and fix bugs in our code. There are two types of components: Class and Functional. 

A Class component requires "extends React.Component" and "render" in order for the component to return HTML, thus making it more complex than functional components. Also known as the stateful component because they can hold or manage a local state.

```
class Header extends React.Component {
 render() {
  return <h1>Header</h1>;
}
```
**Component name should always begin with an uppercase letter**

A Functional component is the preferred method as the code is cleaner. They are also known as the stateless component since they do not have their own state. Functional components are JavaScript functions that can receive data as parameters. For example:

```
Function Header() {
    return <h1>Title</h1>
} 
```

Components are an essential part of building a React application. They are separate pieces of code which are brought together under a parent component to create your masterpiece!
HTML Semantics
Tags: webdev, beginners, tutorial, html
Published: 2023-10-07 17:35:33

Html semantics was introduced in HTML 5 by the introduction of semantic elements. Semantic elements mean elements that have meaning.

Text was divided in elements using the `div` element. (`div`, short for 'divider'). Now, there are many other elements that can be used `<article>`, `<section>`, `<header>`, `<footer>`, `<nav>` and so much more.

The `<b>` or bold element is now replaced by the `<strong>` element.
The `<i>` or italic element is now replaced by the `<emphasis>` element.

They are still there, i mean replaced in common modern usage.

#### div everything, why complicate it? 

Well, the introduction of semantics have been of immense benefit. 

For starters, search engines are now much better at understanding the context of the webpage. A navigation element might include titles of other topics. Without the element being highlighted as a navigation element by using the <nav> element, it would be harder for the search engine to know that the page is not about the titles included in the navigation. 

Secondly, webpages with semantic elements have a higher SEO (search engine optimization) score ranking them higher in the search results.

Thirdly, screen readers will be better at reading content, they could skip reading the navigation or start reading the main content only so it's better for accessibility.

Let's look at some of the usage cases of some of the most common semantic elements.

`<main>`

Published: 2023-10-07 17:16:39

As happy as we get to see the human-like responses of `ChatGPT` by `OpenAI`, they might not be the best friend of a `developer`.

Being a developer we are a little biased towards `structured data` (remember structures or oops, or rdbms?).

ChatGPT came up with a way of providing structure to its responses.

Here is [my Medium article](https://medium.com/@shardul9/harnessing-structure-in-conversations-schema-driven-chatgpt-interactions-38369bab516c) to understand how we can get ChatGPT response as a pre-defined schema.

My journey to DEV-life
Tags: webdev, journey, programming, opensource
Published: 2023-10-07 16:03:02

Recently I sat for an HR Interview for the post of LAMP stack. The HR asked me a few questions why did I choose this career path as an option? , When did I realize that I would be pursuing a Dev-career? Why it took me 5 years to realize that "Physics" was not for me?  
I gave her the answers which were honest, true and the reality of my journey.
Let me start from the beginning when I was pursuing my bachelor's degree in physics, in the 4th semester we happened to learn flowchart and Fortran, which was apparently one of the toughest programming languages. I hated it, the implications were not clear to me, and I was not sure why I was learning that and how to build logic. It's funny that I was good in maths during my 12th std. This trauma of learning programming language and its furious theory was not done, there was another semester to pass with the added good grades of C-programming. This one was a bit easy to grasp. That was the phase where I got a tiny bit of interest in this new subject. I understood that with my fingertip, I could make my computer dance. Now coming back to the point of why I wasted 5 years of my life deciding which career I want to pursue. There are two reasons, The first one is due to financial conditions I never wanted to take admissions in the Tech domain, and the second yet funny reason was I didn't have the knowledge that CSE is an amazing career to explore. Then I did my Master's In physics too, cause my friends were doing that, and even though I was interested in programmes I had no hint that without doing engineering I could pursue an amazing tech career, until and unless one friend of mine(who is a data scientist) suggested me to. Cut to now I am learning, making projects watching documentaries, and reading articles. I have goals, I did make a change for my great life. Now the question is, physics is also amazing, it also has great career opportunities. Yes, it does, but it's the realization which hit me that this subject is not for me. Even if I get the opportunity to do PhD, I will be an empty vessel with regrets, and unable to explain how beautiful and beautiful subject physics is.
Thank you for your patience in reading my journey.Willing to post my knowledge every day. I do post on Git Hub. You can follow me on Linkedin too.

In the evolving digital landscape, [Nostr-Passport](https://github.com/nosdav/passport-nostr) presents itself not as a spectacle but as a humble tool, quietly enabling a seamless and private user experience across various web frameworks, such as Express, Koa, Fastify, and Hapi.

## NIP-07: Privacy-Centric Identification

NIP-07 offers a protocol that facilitates identification (answering the "Who am I?") with a notable degree of privacy, allowing users to interact with applications in a read-only mode without surrendering any personal data to the digital ether.

## NIP-98: Transitioning to Contribution

When users decide to shift from browsing to contributing, NIP-98 steps in, providing authentication (affirming "Verify who I am") by sending a signed header to the server, ensuring the user's contributions are authenticated and accepted.

## Nostr-Passport: Bridging Identification and Authentication

Nostr-Passport serves to validate the header sent via NIP-98, unobtrusively linking identification and authentication to ensure a clean, modular, and scalable user experience.

## Layered Access Control: Node-ACL and Casbin

Integration with nostr-passport allows for the subtle layering of access control using Node-ACL or Casbin, creating a secure environment where access is not only regulated but also precisely defined and controlled.


## Towards Socially Aware Cloud Storage

This approach quietly transforms into socially aware cloud storage, implementing diverse roles and access in a manner that is both effective and unassuming. It creates a scenario where platforms, such as Wikipedia or private journals, can exist harmoniously, each with unique access controls and shared access to secrets.

## Relays and Cloud: Navigating Towards Infinite Storage

Nostr relays, proficient in enabling real-time updates and storage, when amalgamated with cloud technology, elevate their capabilities to archival levels, providing significantly enhanced storage. This pairing doesn't just alleviate pressure on the relays but also propels Nostr towards a scale that could cater to millions or even billions of users, smoothly navigating towards infinite storage.

## In Closing: A Powerful Tool for a Scalable Future

Nostr-Passport quietly nudges us towards a future where digital interactions are secure, private, and scalable, without the fanfare but with a steadfast reliability that promises a future where user privacy and contribution are harmoniously balanced.

As we explore this unassuming yet potent tool, we find a future where browsing and contributing online are not only secure and private but also infinitely scalable and quietly efficient.
JavaScript - Functional Programming Concepts
Tags: javascript, webdev, programming, tutorial
Published: 2023-10-07 15:30:00

Functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. Understanding and applying functional programming concepts can lead to more robust, maintainable, and bug-free code. Here are some key functional programming concepts to master:

- **Pure Functions:** Pure functions are functions that have no side effects and always produce the same output for the same input. They don't modify external state or data. Embracing pure functions makes your code predictable and easier to reason about.

   ```javascript
   // Pure function example
   function add(a, b) {
     return a + b;
   }
   ```

- **Immutability:** Avoiding mutable data helps prevent unexpected changes to variables and data structures. Instead of modifying existing data, create new data when needed.

   ```javascript
   // Immutable data example
   const originalArray = [1, 2, 3];
   const newArray = [...originalArray, 4];
   ```

- **First-Class and Higher-Order Functions:** In functional programming, functions are first-class citizens, meaning they can be passed as arguments to other functions and returned as values from functions. Higher-order functions are functions that take other functions as arguments or return them.

   ```javascript
   // Higher-order function example
   function applyOperation(operation, a, b) {
     return operation(a, b);
   }

   console.log(applyOperation(add, 3, 4)); // 7
   ```

- **Function Composition:** Combining functions to create more complex functions is a fundamental concept. Function composition allows you to build larger operations from smaller, reusable functions.

   ```javascript
   // Function composition example
   function compose(f, g) {
     return function (x) {
       return f(g(x));
     };
   }

   function double(x) {
     return x * 2;
   }

   function square(x) {
     return x * x;
   }

   const doubleThenSquare = compose(square, double);
   console.log(doubleThenSquare(3)); // 36
   ```

- **Recursion:** In functional programming, recursion is often used instead of loops for repetitive tasks. Understanding recursive techniques is essential for solving complex problems efficiently.

   ```javascript
   // Recursive function example (factorial)
   function factorial(n) {
     if (n === 0) return 1;
     return n * factorial(n - 1);
   }

   console.log(factorial(5)); // 120
   ```

- **Immutable Data Structures:** Libraries like Immutable.js provide data structures that are inherently immutable, making it easier to manage state in a functional way.

- **Avoiding Side Effects:** Functional programming encourages minimizing side effects (e.g., console.log, global variables, and network requests) to make code more predictable and testable.

Functional programming can be a powerful paradigm for writing clean, maintainable, and reliable code. By mastering these concepts, you can become a more proficient JavaScript developer and apply functional principles to a wide range of programming challenges.

Happy coding and happier brakes!
Tags: productivity, microservices, beginners, coding
Published: 2023-10-07 14:50:11

Hey there, savvy developers! It's the weekend, and you're probably tempted to spend another couple of hours grinding away at your latest project. Hold on a second. Have you considered that taking a break could actually make you more productive?

## The science behind the pause

Taking a break isn't just about vegging out; it's backed by science. When you take time off, your brain gets to rest and rejuvenate. This process is crucial for problem-solving and creative thinking. You'll find that taking a breather can offer fresh perspectives on coding challenges you might be grappling with.

## Quality over quantity

Coding for longer hours doesn't always mean you're getting more done. Let's be honest, after a certain point, you're just staring at the screen, and your code starts to look like a random jumble of characters. A well-timed break can sharpen your focus, leading to higher quality code.

## A break doesn't have to be long

You don't need a two-week vacation to experience the benefits. Even short breaks, like a 20-minute walk or a quick meditation session, can do wonders for your mental agility.

## What to do during your break

1. **Physical Exercise**: A quick jog or some yoga can do wonders.
2. **Meditation**: Clears the mind, making room for new ideas.
3. **Hobbies**: Dive into something completely unrelated to coding.

### One more thing before you go

If you're interested in exploring a super convenient way to develop websites, don't forget to check out [WebCrumbs](https://github.com/webcrumbs-community/webcrumbs), our GitHub repository. Think of it as Wordpress for React. Go ahead and give it a star if you find it useful.

Happy coding and happier breaks!
