How to Use JSON Files in React JS
Tags: javascript, beginners, programming, react
Published: 2024-06-29 03:58:45

Using **JSON files** in a **React application** can streamline data management and enhance the development experience. This guide will walk you through the steps to create a JSON file, integrate it into your React project, and use it as a fake API server.

**Step 1: Create the JSON File**
First, let’s create a JSON file that contains the data you want to use in your React application.

```
{
  "title": "Frontend Developer",
  "description": "This is a simple example of using JSON in a React app.",
  "items": [
    {
      "id": 1,
      "name": "Item 1",
      "price": 10.99
    },
    {
      "id": 2,
      "name": "Item 2",
      "price": 14.99
    },
    {
      "id": 3,
      "name": "Item 3",
      "price": 9.99
    }
  ]
}
```

**Step 2: Place the JSON File in Your React Project**
To use this JSON file in your React application, place it in the public directory of your React project. This ensures that the file is accessible via a URL when your React app is running. The public directory is typically located at the root of your project structure.

**Here is how your project structure might look:**

```
my-react-app/
├── public/
│   ├── data.json
│   ├── index.html
│   └── ...
├── src/
│   ├── App.js
│   └── ...
├── package.json
└── ...
```
**Step 3: Fetch and Use the JSON Data in Your React Component**
Now, let’s fetch and use this JSON data in a React component. Here’s an example using the useEffect and useState hooks:

```
import React, { useEffect, useState } from 'react';

const App = () => {
  const [data, setData] = useState(null);

  useEffect(() => {
    fetch('/data.json')
      .then(response => response.json())
      .then(data => setData(data))
      .catch(error => console.error('Error fetching data:', error));
  }, []);

  if (!data) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      <h1>{data.title}</h1>
      <p>{data.description}</p>
      <ul>
        {data.items.map(item => (
          <li key={item.id}>
          Name:  {item.name} and Price: ${item.price}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default App;
```


**Step 4: Run Your React Application**
Make sure your React application is running by using npm start or yarn start. You should see the data from data.json being displayed in your application.

# 👶 The Belly Button Story: Why Do We Have Belly Buttons? 👶

The belly button, or navel, is a familiar feature on our bodies, yet its origins and significance are often overlooked. This small scar is a reminder of our early development in the womb and the vital connection between mother and baby. But why do we have belly buttons, and what role does it play in our anatomy? Let&#x27;s delve into the story of the belly button and its significance in human development.

# 🔬 The Science of the Belly Button 🔬

The belly button is the scar left behind after the umbilical cord, which connected you to your mother in the womb, is cut after birth. The umbilical cord was essential for providing nutrients and oxygen during fetal development.

## 🧠 How the Belly Button Forms 🧠

1. **Fetal Connection**: During pregnancy, the umbilical cord connects the developing fetus to the placenta, allowing the exchange of oxygen, nutrients, and waste products between the mother and the baby.
2. **Birth Process**: After birth, the umbilical cord is clamped and cut, leaving a small stump attached to the baby&#x27;s abdomen.
3. **Healing and Scar Formation**: Over the next few weeks, the umbilical stump dries out, falls off, and heals, leaving behind the belly button as a scar.

# 🌍 The Significance of the Belly Button 🌍

The belly button serves as a reminder of our early development and the crucial role the umbilical cord played in sustaining us before birth.

### 🌟 Fetal Development:
- **Nutrient Supply**: The umbilical cord provided all the necessary nutrients and oxygen needed for the developing fetus to grow and thrive in the womb.
- **Waste Removal**: It also facilitated the removal of waste products from the baby&#x27;s bloodstream, ensuring a healthy environment for development.

### 👶 Post-Birth Connection:
- **Health Indicator**: In some cultures, the belly button is believed to be an indicator of a baby&#x27;s health and well-being.
- **Cultural Significance**: The belly button has cultural and symbolic meanings in various societies, often associated with birth, life, and connection.

# 🌟 Embracing Our Origins 🌟

The belly button is more than just a small scar on our abdomen. It&#x27;s a symbol of our early life, the connection we had with our mothers, and the incredible process of human development.

Next time you look at your belly button, remember the fascinating journey it represents. Let&#x27;s celebrate the story of the belly button and the remarkable biology that explains why we all have this unique feature.

# 🧊 The Chilling Mystery of Brain Freeze: Why Do We Get It? 🧊

Imagine you&#x27;re enjoying a delicious ice cream cone on a hot day, and suddenly, you feel a sharp, intense headache that seems to come out of nowhere. This unpleasant sensation is known as brain freeze, and it has puzzled ice cream lovers for generations. But why does brain freeze happen, and what can we do to avoid it? Let&#x27;s dive into the science behind this chilling phenomenon.

# 🔬 The Science of Brain Freeze 🔬

Brain freeze, or ice cream headache, occurs when something cold touches the roof of your mouth (palate). This sudden temperature change triggers a series of reactions in the blood vessels and nerves in your mouth and head.

## 🧠 How Brain Freeze Happens 🧠

1. **Cold Stimulus**: When you eat or drink something very cold, it rapidly cools the blood vessels in the roof of your mouth.
2. **Vasoconstriction**: The cold causes these blood vessels to constrict (narrow) quickly.
3. **Vasodilation**: Almost immediately, the blood vessels dilate (expand) to warm the area back up.
4. **Pain Signals**: This rapid constriction and dilation send pain signals through the nerves to the brain, particularly affecting the trigeminal nerve, which is responsible for facial sensations.
5. **Referred Pain**: The brain interprets these pain signals as coming from the forehead, resulting in the sensation of a headache.

# 🌡️ Why Does Brain Freeze Happen? 🌡️

Brain freeze is thought to be a protective mechanism. The rapid changes in blood vessel size and the subsequent pain signals may serve to protect the brain from extreme temperature fluctuations. This reaction prompts you to slow down and avoid consuming cold substances too quickly, which could potentially harm the delicate tissues in your mouth and throat.

# 🥶 How to Prevent and Relieve Brain Freeze 🥶

While brain freeze can be quite uncomfortable, there are simple ways to prevent and alleviate it.

### 🛑 Prevention Tips:
- **Eat Slowly**: Take smaller bites or sips of cold foods and beverages to avoid sudden temperature changes in your mouth.
- **Warm the Roof of Your Mouth**: Press your tongue against the roof of your mouth to warm it up.
- **Drink Warm Water**: Sip warm water slowly to counteract the cold stimulus.

### 💡 Relief Tips:
- **Cover Your Mouth**: Cup your hands over your mouth and breathe in warm air to warm the palate.
- **Tilt Your Head Back**: This can help reduce blood flow to the brain and relieve pain.
- **Massage Your Temples**: Gently massaging your temples can help alleviate the headache.

# 🌟 Enjoying Cold Treats Without the Pain 🌟

Brain freeze is a temporary but intense sensation that can put a damper on enjoying your favorite cold treats. By understanding the science behind it and following a few simple tips, you can savor your ice cream and other chilly delights without the dreaded headache.

So next time you indulge in a frosty treat, take it slow and enjoy the moment, knowing you&#x27;re equipped to handle any brain freeze that might come your way.

# 🌟 Glowing Wonders: Why Do Some Animals Glow in the Dark? 🌟

From the enchanting glow of fireflies to the eerie luminescence of deep-sea creatures, bioluminescence is one of nature&#x27;s most magical phenomena. But why do some animals glow in the dark? Let&#x27;s dive into the captivating world of bioluminescence and discover the science behind these natural light shows.

# 🔬 The Science of Bioluminescence 🔬

Bioluminescence is the production and emission of light by living organisms. This light is produced through a chemical reaction that occurs within special cells or organs. The key components of this reaction are luciferin (a light-emitting molecule) and luciferase (an enzyme that catalyzes the reaction).

## 🧪 How Bioluminescence Works 🧪

1. **Luciferin and Luciferase**: The enzyme luciferase catalyzes the oxidation of the molecule luciferin, resulting in the emission of light.
2. **Energy Release**: During this reaction, chemical energy is converted into light energy, producing a visible glow.
3. **Control Mechanisms**: Bioluminescent animals can often control the timing and intensity of their light emission through various biological mechanisms, such as neural or chemical signals.

# 🌍 The Purposes of Bioluminescence 🌍

Bioluminescence serves various functions in the animal kingdom, each playing a vital role in the survival and behavior of these glowing creatures.

### 🎣 Attracting Prey:
- **Luring Prey**: Some deep-sea predators use bioluminescence to attract unsuspecting prey. The light acts as a lure, drawing the prey closer to the predator.

### 🛡️ Deterring Predators:
- **Startling Predators**: Sudden flashes of light can startle or confuse predators, giving the bioluminescent animal a chance to escape.
- **Warning Signals**: Some animals use their glow as a warning signal to indicate that they are toxic or unpalatable.

### 💬 Communication:
- **Mating Signals**: Fireflies are famous for their bioluminescent courtship displays. Males and females communicate through specific light patterns to find and attract mates.
- **Social Interaction**: In some species, bioluminescence is used for social interactions, such as signaling group movements or territory boundaries.

### 🌠 Camouflage:
- **Counter-Illumination**: Some marine animals use bioluminescence to blend in with the faint light from the surface, effectively camouflaging themselves from predators below.

# 🌌 Nature&#x27;s Light Show 🌌

Bioluminescence is not only a mesmerizing spectacle but also a fascinating adaptation that highlights the incredible diversity and ingenuity of life on Earth. From the depths of the ocean to forest floors, glowing animals have evolved to harness light for survival in a variety of ways.

Next time you encounter a firefly or see images of glowing deep-sea creatures, you&#x27;ll know that their bioluminescent beauty serves important purposes in their lives. Let&#x27;s celebrate these glowing wonders and the remarkable science that allows them to light up the night.
Resin Sources: Understanding the Chemistry Behind Composite Formulation

A Primer on Composite Resin Chemistry
The Resin and Fibers in Composite Materials Central to composite materials is a unique combination of resin, fibers that they work as group make them valuable for numerous applications that demand strength. We hope that by giving you an understanding of the basic building blocks these thread locking fluid materials are comprised of as well how they form into large rigid structures and work with fibers, we can help to show one path in which engineers may construct their own resins for ultra-tough composites suitable for industries such as aerospace through construction.

Composites rely heavily on resins to bind the fibers together and imbue them with certain properties. Resins come in two varieties, each with its pros. While some resins can remain strong under harsh conditions others are easy to be recycled or repaired. The type of resin, e.g. epoxy or polyester can also affect how the final product appears

How resins interact with fibers is key to composite manufacture. The strength of the final product is influenced by things such as how well resins stick to fibers and also what thickness they are. Depending on the need, different clear epoxy resin are used; Epoxy is generally stronger and more expensive than polyester forCellulose acetate or "celluloid"; this plastic imitates the look of ivorine but lacks its working ability.

Composites and resin are getting better with new revolutions in technologies. Resins are also being toughened with very small particles (nanofillers) that make them less likely to tear but do not significantly increase their weight. Plant-based resins are also becoming more common due to their earth-friendly nature. Certain resins can even be self-healing when they become damaged, making parts last longer and generally cheaper to maintain.

Through their knowledge of resins, manufacturers can create customized composites that have unique features... which means fiber reinforced plastics composite materials could be fire resistant or more durable:variables. So this supports in designing materials for uses like invisibility of planes to radar or building strong bridges. Resin chemists know how to accomplish these dual goals of making composite materials which meet industry requirements while preserving the environment.

Bottom line is that resin chemistry, in great part, determines how composite materials are made and to what extent they perform. Many of these breakthroughs are still in the lab, but as we better understand how resins work and develop new technologies around them composite thread locking compound materials will continue to evolve into an even more formidable foe - not only for all its competitors across multiple industries but also for our ailing planet.
Heliums Funny Effect Why Does Helium Make Your Voice Sound Funny
Tags: helium, voice, science, physics

# 🎈 Helium&#x27;s Funny Effect: Why Does Helium Make Your Voice Sound Funny? 🎈

Inhaling helium from a balloon and hearing your voice turn high-pitched and squeaky is a popular party trick that never fails to amuse. But why does helium have this funny effect on your voice? Let&#x27;s explore the science behind this phenomenon and how helium changes the sound of your voice.

# 🔬 The Science of Helium and Sound 🔬

Helium is a lighter-than-air gas that affects the way sound waves travel through it. When you inhale helium, it temporarily changes the properties of the air in your vocal tract.

## 🧠 How Helium Affects Your Voice 🧠

1. **Density Difference**: Helium is much less dense than regular air, which is primarily composed of nitrogen and oxygen. This lower density changes the speed at which sound waves travel through the gas.
2. **Increased Frequency**: Sound waves travel faster through helium than through regular air. When you speak after inhaling helium, the sound waves produced by your vocal cords move faster, increasing the frequency of the sound waves.
3. **Higher Pitch**: The increased frequency of the sound waves results in a higher pitch, making your voice sound higher and squeakier than usual.

# 🌍 The Principles of Sound and Density 🌍

Sound is a vibration that travels through a medium, such as air, water, or solid objects. The speed of sound depends on the density and elasticity of the medium through which it travels.

### 🌀 Sound Wave Mechanics:
- **Frequency and Pitch**: The frequency of a sound wave determines its pitch. Higher frequencies correspond to higher-pitched sounds, while lower frequencies correspond to lower-pitched sounds.
- **Medium Density**: In a denser medium, sound waves travel more slowly, resulting in lower frequencies. In a less dense medium, like helium, sound waves travel faster, leading to higher frequencies.

### 🎤 Voice Production:
- **Vocal Cords**: Your vocal cords produce sound by vibrating as air passes through them. The pitch of your voice is influenced by the tension and length of your vocal cords, as well as the properties of the air in your vocal tract.

# 🌟 The Fun of Helium Inhalation 🌟

While inhaling helium for a funny voice is a fun and harmless activity when done occasionally, it&#x27;s important to do it safely and in moderation. Inhaling too much helium can displace the oxygen in your lungs, which can be dangerous.

Next time you try the helium voice trick, you&#x27;ll understand the science behind the funny effect. Let&#x27;s celebrate the wonders of physics and acoustics that make our voices sound so amusingly high-pitched when we inhale helium.

CSS Battles: 100% match at daily target (28/06/2024)
Tags: css, beginners, learning
Published: 2024-06-29 02:23:40

It has been a while since I've used some minutes from my side job to solve daily targets from CSSBattles, it's quite relaxing and fun drawing those different and colorful designs. Usually, I have less than thirty minutes to complete the challenge and today I got a 100% match. 

Here's the source code:
```
<div class='container'>
  <div class=rectangle-1></div>
  <div class='rectangle-2'></div>
  <div class='rectangle-3'></div>
  <div class='rectangle-4'></div>
</div>
<style>
  *{
    margin:0;
    padding:0;
    box-sizing:border-box;
  }
  .container {
    width: 100%;
    height: 100%;
    background-color: #6592CF;
  }

.rectangle-1, .rectangle-2, .rectangle-3, .rectangle-4{
    background-color:#243D83;
    position: relative;
}

.rectangle-2,.rectangle-4{
    width:110px;
    height:150px;
}
  
.rectangle-1{
  width:280px;
  height:90px;
  left:60px;
}
  .rectangle-2{

    left:170px;
  }
  .rectangle-4{
    left:230px;
    bottom:180px;
  }
</style>
```
And that's the result I got:

![My solution for CSSBattle daily target (28/06/2024)](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/syyd5d5uypi6rl32itpe.png)

Since I started looking for other users' solutions I've seen them using properties like box-shadow, as you can see in the video below:
{% embed https://www.youtube.com/watch?v=n6zQFLJAUVg %}
It's important to note that while my solution got almost 800 characters, others who used box-shadow had 200 characters maximum, so my goal for the next week will be to learn how to use box-shadow for drawing shapes and improve my daily target performance. 

The CSSBattle site is user-friendly and the code output has the advantage of showing the difference between what you are building and what you need/would like to achieve (target). Also, they provide the hex codes for the colors present in the project and the functionality to share the results on Twitter. Would you like to join?
