Tags: webdev, javascript, beginners, programming
Published: 2024-02-28 18:55:50

Microservices and a React app:

### Microservice 1: Service A

1. Create a new directory for Service A.
2. Inside the directory, create a `package.json` file:

```json
{
  "name": "service-a",
  "version": "1.0.0",
  "main": "index.js",
  "dependencies": {
    "express": "^4.17.1",
    "cors": "^2.8.5"
  }
}
```

3. Run `npm install` to install the dependencies.
4. Create an `index.js` file:

```javascript
const express = require('express');
const cors = require('cors');
const app = express();
const PORT = 3001;

app.use(cors());

app.get('/api/data', (req, res) => {
  res.json({ value: 5, service: 'A' });
});

app.listen(PORT, () => {
  console.log(`Service A is running on port ${PORT}`);
});
```

5. Run Service A with `node index.js`.

### Microservice 2: Service B

1. Create a new directory for Service B.
2. Inside the directory, create a `package.json` file:

```json
{
  "name": "service-b",
  "version": "1.0.0",
  "main": "index.js",
  "dependencies": {
    "express": "^4.17.1",
    "cors": "^2.8.5"
  }
}
```

3. Run `npm install` to install the dependencies.
4. Create an `index.js` file:

```javascript
const express = require('express');
const cors = require('cors');
const app = express();
const PORT = 3002;

app.use(cors());

app.get('/api/data', (req, res) => {
  res.json({ value: 7, service: 'B' });
});

app.listen(PORT, () => {
  console.log(`Service B is running on port ${PORT}`);
});
```

5. Run Service B with `node index.js`.

### React Frontend

1. Create a new directory for the React frontend.
2. Inside the directory, create a `package.json` file:

```json
{
  "name": "frontend",
  "version": "1.0.0",
  "main": "index.js",
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "axios": "^0.24.0"
  }
}
```

3. Run `npm install` to install the dependencies.
4. Create an `index.js` file:

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

function App() {
  const [dataA, setDataA] = useState({});
  const [dataB, setDataB] = useState({});

  useEffect(() => {
    // Fetch data from Service A
    axios.get('http://localhost:3001/api/data')
      .then(response => setDataA(response.data))
      .catch(error => console.error(error));

    // Fetch data from Service B
    axios.get('http://localhost:3002/api/data')
      .then(response => setDataB(response.data))
      .catch(error => console.error(error));
  }, []);

  return (
    <div>
      <h1>Microservices Example</h1>
      <p>Value from Service A: {dataA.value} (Service: {dataA.service})</p>
      <p>Value from Service B: {dataB.value} (Service: {dataB.service})</p>
    </div>
  );
}

export default App;
```

5. Run the React frontend with `npm start`.

This example demonstrates how to create modular microservices and fetch data from both services in a React frontend. Adjust the code as needed based on your specific requirements and use case.

Primitive and Non-Primitive (Object) Data Types
Tags: webdev, javascript, beginners, programming
Published: 2024-02-28 18:28:17

**Primitive and Non-Primitive (Object) Data Types:**

- **JavaScript:**
  - **Primitive Data Types:** Number, String, Boolean, Null, Undefined, Symbol (added in ECMAScript 6).
  - **Object Data Type:** Objects (including arrays and functions) are non-primitive.

- **PHP:**
  - **Primitive Data Types:** Integer, Float, String, Boolean, Null.
  - **Object Data Type:** Objects (created from classes or built-in classes like stdClass).

**Pass by Value vs. Pass by Reference:**

- **JavaScript:**
  - **Primitive Types:** Passed by value. Changes inside a function do not affect the original value.
  - **Objects (Non-Primitive):** Passed by reference. Changes inside a function affect the original object.

- **PHP:**
  - **Primitive Types:** Passed by value.
  - **Objects (Non-Primitive):** Passed by reference. Changes inside a function affect the original object.

**Comparison - JavaScript vs. PHP:**

- **JavaScript:**
  - **Syntax Example:**
    ```javascript
    let primitiveValue = 5;
    let objectValue = { key: 'value' };

    function modifyValues(a, b) {
      a = 10;
      b.key = 'modified';
    }

    modifyValues(primitiveValue, objectValue);
    console.log(primitiveValue);  // Output: 5
    console.log(objectValue.key); // Output: 'modified'
    ```

- **PHP:**
  - **Syntax Example:**
    ```php
    $primitiveValue = 5;
    $objectValue = (object)['key' => 'value'];

    function modifyValues($a, $b) {
      $a = 10;
      $b->key = 'modified';
    }

    modifyValues($primitiveValue, $objectValue);
    echo $primitiveValue;        // Output: 5
    echo $objectValue->key;      // Output: 'modified'
    ```

In both languages, primitive types are passed by value, and objects (non-primitive) are passed by reference. The behavior ensures that changes made to objects inside a function are reflected outside the function.

Note: While objects in JavaScript are always passed by reference, primitive types are immutable, meaning their values cannot be changed. In PHP, it's possible to explicitly pass a variable by reference using the `&` symbol in the function parameter list.

How to Divorce in New York City: A Step-by-Step Guide

Divorce can be a complex and emotionally challenging process, but understanding the legal steps involved can help you navigate it more smoothly. If you're considering divorce in New York City, here's a step-by-step guide to help you understand the process:

Residency Requirements: To file for [divorce in New York](https://srislaw.com/how-to-get-divorce-in-new-york/), either you or your spouse must have lived in the state continuously for at least two years before starting the divorce process. If you were married in New York and either you or your spouse has lived in the state for at least one year before filing, you can also file for divorce.

Grounds for Divorce: New York allows for both fault-based and no-fault grounds for divorce. No-fault divorce can be filed if the marriage has been irretrievably broken for at least six months. Fault-based grounds include cruel and inhuman treatment, abandonment, imprisonment, and adultery.

Filing the Divorce Petition: The first step in the divorce process is to file a "Summons with Notice" or a "Summons and Verified Complaint" in the Supreme Court in the county where either you or your spouse resides.

Serve the Divorce Papers: After filing, you must serve your spouse with a copy of the divorce papers. This can be done by a third-party over the age of 18 or by a professional process server.

Response: Your spouse has 20 days (if served in person) or 30 days (if served by other means) to respond to the divorce papers. They can either contest the divorce or agree to the terms.

Discovery and Settlement: If the divorce is contested, both parties may engage in discovery to gather information and evidence. They may also attempt to reach a settlement through negotiation or mediation.

Court Proceedings: If a settlement cannot be reached, the divorce case will go to court. Each party will present their case, and the judge will make a decision on the terms of the divorce, including division of assets, child custody, and support.

Final Judgment: Once the court issues a judgment of divorce, the marriage is legally dissolved. The judgment will outline the terms of the divorce, including any financial obligations or custody arrangements.

Post-Divorce Matters: After the divorce is finalized, both parties must comply with the terms of the judgment. This may include paying child support, dividing property, or other obligations outlined in the judgment.

Appeals and Modifications: Either party has the right to appeal the court's decision within a certain timeframe. Additionally, either party can request modifications to the judgment if circumstances change, such as a change in income or custody arrangements.

It's important to note that divorce laws and procedures can vary, so it's advisable to consult with a qualified attorney who specializes in family law in New York City to guide you through the process and protect your rights.

An Intro to JavaScript.
Published: 2024-02-28 17:30:17

Hi everyone,Today we will discuss about the World's popular Programming Language to develop Web Applications is **JavaScript**.

We have HTML,CSS to design Web Applications, but to make an interaction javascript will take care of that.

It is a scripting language that enables to create dynamically updating content, control multimedia, animate images, and everything else.

**How To include Javascript in HTML?**

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/d7eanar8oqrhcaj3s0qq.png)

We use **script** tag to include javascript file into the html.

**Features of JavaScript**:

**Client Side**: It supplies objects to control a browser with DOM(Document Object Model). To make this easy there are some libraries like ReactJS,Angular JS, Vue JS.

**Server Side**: It supplies objects relevant to running JavaScript on a server. To make it possible it has framework called Node JS.

**Dynamic Type**: It means types of the variables are defined based on the stored value.

**Platform Independent**: It means that you can simply write the script once and run it anywhere and anytime.

**Prototype-based Language**: It uses prototypes instead of classes or inheritance means we can define an object prototype, and then more objects can be created using object prototype.

This is a brief Introduction to JavaScript, we can learn more in coming days.
See you soon😊😊😊
