React & WebSocket Simple Chat App
Published: 2024-01-03 06:36:09

Here is an example of how you can implement a simple chat application in React using WebSocket and state management:

1. **Create a new React app:**

   ```bash
   npx create-react-app react-chat-app
   cd react-chat-app
   ```

2. **Install dependencies:**

   Install `ws` for WebSocket server on the backend:

   ```bash
   npm install ws
   ```

3. **Create a WebSocket server:**

   Create a file named `server.js` in the root directory:

   ```javascript
   const WebSocket = require('ws');
   const wss = new WebSocket.Server({ port: 8000 });

   wss.on('connection', (ws) => {
     ws.on('message', (message) => {
       wss.clients.forEach((client) => {
         if (client !== ws && client.readyState === WebSocket.OPEN) {
           client.send(message);
         }
       });
     });
   });
   ```

   Start the WebSocket server:

   ```bash
   node server.js
   ```

4. **Update `src/App.js` for the React frontend:**

   Replace the contents of `src/App.js` with the following:

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

   const App = () => {
     const [messages, setMessages] = useState([]);
     const [messageInput, setMessageInput] = useState('');
     const [socket, setSocket] = useState(null);

     useEffect(() => {
       const newSocket = new WebSocket('ws://127.0.0.1:8000');

       newSocket.onopen = () => {
         console.log('Connected to WebSocket');
       };

       newSocket.onmessage = (event) => {
         const newMessages = [...messages, event.data];
         setMessages(newMessages);
       };

       setSocket(newSocket);

       return () => {
         newSocket.close();
       };
     }, [messages]);

     const handleSendMessage = () => {
       if (socket && messageInput.trim() !== '') {
         socket.send(messageInput);
         setMessageInput('');
       }
     };

     return (
       <div>
         <div>
           {messages.map((message, index) => (
             <div key={index}>{message}</div>
           ))}
         </div>
         <div>
           <input
             type="text"
             value={messageInput}
             onChange={(e) => setMessageInput(e.target.value)}
           />
           <button onClick={handleSendMessage}>Send</button>
         </div>
       </div>
     );
   };

   export default App;
   ```

5. **Run the React app:**

   Start the React app:

   ```bash
   npm start
   ```

   Visit `http://localhost:3000` in your browser, and you should see a simple chat interface. Open multiple tabs or browsers to simulate different users, and you should see messages broadcasted in real-time.

This example demonstrates a basic React app with WebSocket communication for real-time chat. In a real-world scenario, you may want to add user authentication, error handling, and additional features. Additionally, consider deploying the WebSocket server to a production environment for a scalable solution.

Published: 2024-01-03 06:30:51

For highly skilled developers working in remote teams, productivity is paramount. The key lies in smart management of time and resources. Here’s a concise, direct approach to ramping up your team’s efficiency, focusing on the practical application of time tracking software alongside other impactful strategies.

**1. Time Tracking Software:** 
Integrating a robust time tracking tool is crucial. It’s not just about [monitoring hours](https://apploye.com/remote-employee-monitoring); it’s about understanding task durations and pinpointing inefficiencies. For developers, this means identifying which parts of the project are time-intensive and need optimization. Choose a tool that integrates seamlessly with your existing development and project management software, providing real-time insights and analytics.

**2. Agile Methodologies:**
Incorporate Agile methodologies like Scrum or Kanban. These frameworks, coupled with effective time tracking, can significantly enhance task management and prioritization, leading to more efficient sprints and better resource allocation.

**3. Automated Workflows and Integrations:**

JavaScript Strings and String Methods as a Beginners you should know
Tags: javascript, beginners, webdev, programming
Published: 2024-01-03 06:07:16

## String:
String is basically a sequence of characters that is used for storing and managing text data. JavaScript String is primitive data types and are immutable(means you cannot change the original string).There are two ways to create a string.

**Using String Literals**

`let name = "Hello World";`

here you have to enclosed the text inside the double or single quotes.

**Using String Object**

`let name = new String("Hello World");`

## String Methods :

**charAt Method:** returns the character from a specified index.

```
let name = "Hello World";
let value = name.charAt(1);
console.log(value);
//value = e
```
**concat method:** Join two or more string together

```
let str = "Hello ";
let str1 = "World";
let total = str.concat(str1);
console.log(total);
//total = Hello World
```
**replace method:** replace the given string with specified replacement values

```
let str = "Your name";
let replaceValue = str.replace("Your", "My");
console.log(replaceValue);
//My name
```
**search method:** It searches a string against a specified values or regular expressions

```
let text = "Please keep quiet!";
console.log(text.search("keep"));
console.log(text.search(/quiet/));
// 7
//12
```
_note:_ it will return the first occurrence of the string.

**indexOf method:** It return the index of first occurrence of the string. It cannot take regular expression values.

```
let text = "Move ahead!";
let index = text.indexOf("ahead");
console.log(index);
//5
```

**split method:** convert a string into array

```
let text = "Move ahead!";
let value = text.split(" ");
console.log(value);

//[ 'Move', 'ahead!' ]
```

**slice method:**  extracts a part of a string and returns the extracted part in a new string.
it takes start position and end position(not included) in parameter.

```
let text = "Move ahead!";
let value = text.slice(6, 10);
console.log(value);

//head
```

Multi-dimensional Array
Tags: array, programming, beginners, tutorial
Published: 2024-01-03 05:59:17

Each element of multi dimensional array is an array. This is why it is called as array of arrays.

Syntax:
`int arr[2][3];`

int - datatype
arr - name of array.
2 - there will be two arrays inside this array.
3 - each array will have 3 elements.

`int arr[2][3] = {{1,2,3}, {6,7,8}};`

## Access array elements
```
int arr[2][3] = {{1,2,3}, {6,7,8}};
    
    printf("%d ", arr[0][0]); 
    printf("%d ", arr[1][2]);
```
Here 1 is the second array and 2 is the third element in this array.

## Change array values.
```
int main() {
    
    int arr[2][3] = {{1,2,3}, {6,7,8}};
    
    arr[0][2] = 7;
    arr[1][1] = 8;
    
    printf("%d", arr[0][2]);
    printf("%d", arr[1][1]);

    return 0;
}
```

## Multidimensional array using for loop
```
#include <stdio.h>

int main() {
    
    int arr[2][3] = {{1,2,3}, {6,7,8}};
    
    for(int i=0; i<2; i++){
        for(int j=0; j<3; j++){
            printf("%d ", arr[i][j]);
        }
    }

    return 0;
}
```

First for loop for each arrays inside and the second for loop is for the elements inside each array.

## Manage database

### Add table

1. Create migration by using `supabase migration new create_some_table`
2. Edit `{timestamp}_create_some_table.sql`. and add query.
3. Apply to databases by using `supabase db reset`.

#### If I changed it in GUI?

You need to apply difference to migration file by using `supabase db diff -f {table_name}`

NFTs as first class citizens
Tags: web3, nfts, cosmwasm, programming
Published: 2024-01-02 21:50:11

## The idea
NFTs are a staple of crypto technology, and are still being integrated as an afterthought, even on the most powerful blockchain framework around; cosmos. This plan will make it easy to make NFTs (And developers) first class citizens on cosmos, with a new Cosmos SDK module.

## The plan
This will be made possible by building a series of native cosmos SDK modules which will derive the CW721 spec, as well as modules for the native exchange of NFTs on a chain based order-book, similar to Injective's chain order-book and AMM for CW20 tokens.

## Modules
There will be 3 modules:
- CW721 - The core chain module which allows for the storage of data on-chain. This will be primary functions like minting, sending, burning, etc.
- Exchange - The primary order-book system. This will allow for the buying, selling, and auctioning of NFTs.
-  Registry - an index and global registry of all NFTs. NFTs will be stored with unique identifiers. (more later on)

## Core module - CW721
The core module will be a standard implementation of CW721 version 18 (or latest at time of development), or, will implement x/NFT (ADR 43) if it passes. This may, however, become a purely custom module, and will not be implemented in the standard cosmos-sdk.

## Exchange
This will likely be a global order-book, which allows for buying, selling, listing, and offering. These will all be native messages. This will allow for seamless UI integration and easy white-labeling. this takes most of the work, as well as the "Who does it best" from the exchange side of things, and allows projects to focus on top-tier UI, better client offerings, etc.

## Registry
This will be a global, indexable, registry of all NFTs on chain. This will allow for easy searching of all NFTs on chain by their UUID. This UUID will be a base64 (otherwise TBD) name comprised of the token's contract/classID and TokenID concatenated together like `class:token`. The registry will store on-chain metadata, the owner of a token, and the URI to the media. This will also allow for an easy integration of domains, which can be indexed via hash-table to get the ID, then indexed by the registry for owner and metadata info.

## Tech
The modules will likely function as a smart contract with a native wasm interpreter layer, using the go based wasmvm as its interpreter, this will mean a fork of wasmvm/wasmd and adding either the unbuilt contracts and having a build layer, or a built wasm contract embeded. All repos will be available on the Nebula github org.
