Style a DataTable in React Native Paper
Published: 2023-12-06 07:03:33

The DataTable component in React Native Paper provides a clean and customizable way to display tabular data on mobile. However, out of the box, it comes with default styling that may not always fit with the design and styling of your application. Fortunately, the DataTable is fully customizable through React Native styling, which allows you to precisely control elements like colors, spacing, borders, and more to match your branding and user interface guidelines.

Styling the DataTable correctly is important to provide a consistent and polished experience for users when viewing and interacting with lists of data. This article will demonstrate some common techniques for styling the key elements of the DataTable, such as the header, rows, and individual cell content, to achieve a custom look and feel.

## Here's the Tips to Style a DataTable in React Native Paper

import React Native Paper and the DataTable component:

```jsx
import { DataTable } from 'react-native-paper';
```
Define some sample data as an array:

```js
const data = [
  {
    id: 'bd7acbea-c1b1-46c2-aed5-3ad53abb28ba',
    firstName: 'First Name 1',
    lastName: 'Last Name 1'
  },
  {
    id: '3ac68afc-c605-48d3-a4f8-fbd91aa97f63',
    firstName: 'First Name 2',
    lastName: 'Last Name 2'
  },
  // etc
];
```
Render the DataTable passing in the data:

```jsx
<DataTable>
  <DataTable.Header>
    <DataTable.Title>Id</DataTable.Title>
    <DataTable.Title>First Name</DataTable.Title> 
    <DataTable.Title>Last Name</DataTable.Title>
  </DataTable.Header>

  <DataTable.Row>
    // map over data
  </DataTable.Row>
</DataTable>
```
To style it, wrap it in a StyleSheet:

```jsx
<StyleSheet>
  <DataTable 
    style={{
      borderColor: 'blue' 
    }}
  >
    //...
  </DataTable>
</StyleSheet>
```
You can then style individual components like Header, Title, Row etc:

```jsx
<DataTable.Title 
  style={{
    color: 'green'
  }}
>
  First Name
</DataTable.Title>
```
Some other useful styles include controlling padding, borders, text colors, sizes etc.

The DataTable component provides a solid foundation for displaying tabular data on mobile while also giving developers full control over styling through React Native. With some basic use of StyleSheet definitions and component-specific styles, you can customize elements like colors, sizing, spacing, and more to match any design. Taking the time to style the DataTable carefully ensures a polished user experience when viewing lists of information.
Whether you need to adjust colors or achieve a completely bespoke design simply, the styling capabilities allow you to integrate tabular content into your unique UI perfectly. For professional [React JS Development](https://positiwise.com/technologies/reactjs-development) teams and independent developers alike, leveraging these styling techniques provides an effective way to build out feature-rich, customizable data browsing experiences with React Native Paper.

So I took down my external monitor.

![My Desk Before](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kardi5id6bo8tzy1vy2i.png)

About three months ago I hooked up my 27" monitor, a bluetooth keyboard, some book-shelf speakers and was pretty happy... until I wasn't... today. 

The monitor is showing some signs of ghosting, and everyone once in a while it flickers. I really didn't want the Apple Magic Keyboard (external) because of the janky arrow keys, so I bought what I thought was the best BT keyboard I could find. It takes 2.5 seconds to re-connect, it often "fights" with whatever signal my Magic Mouse was using, jets out some random characters, and finally connects. It doesn't have touch-id so I have been manually typing my super-hard password everyday! I mis-type it about half the time. I had to use the bookshelf speakers remote control to switch it to Bluetooth before my computer would connect to it, so I also bought a dock and wired it, but I still had to turn them on....

I think you get the point. It just never works out for me when I try to do this... An external monitor is nice, but the setup always comes with some price I have to pay.

My MacBook Air has a screen and a keyboard ATTACHED to it, and it works...all the time! 

So, I took all that shit down and am just back on my 💻

![My Desk Now](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0tapc97og0gpopkdvrc5.jpeg)

...again.

It always feels weird going from this big-ass screen to this tiny 13" one. My desk always feels a bit empty and barren too...it's always nice to have your desk full of big tech 💪🏻! But, it just isn't meant to be.

I missed ⌨️👈🏻 Touch ID so much.

Bitcoin Circuit Review - Is It Legit or Just A Scam? 2023
Published: 2023-12-06 06:40:00

You simply don't understand it all. Do you want to cop out on giving the feeling of being unintelligent? Should we give it a thumbs down I don't have to diminish the prospects for that. Consequently, most future leaders are ignorant when it's in the same class as that scheme. There are few old conclusions in this area of interest. If a woman could be found somewhere that did not prefer the nuisance I would be surprised. 

I will cover that stereotype in my next article. You need a pair of brass balls for using this. That was a cool display when this can be a diamond in the rough. Every good element can be overplayed. That guide was written with you in mind. This was sort of spliced together. In other places in the world there are interesting a scenario events or this installment should be titled 'Bitcoin Circuit Reviews Secrets Revealed'. 

You need to be really skilled to use this quandary effectively. I have confidence in some opportunity. Why do you desire to say something that gives a critical explanation in respect to my about-face? I think this should be hoisted on its own petard and I might have to give you a fair shake.

NoSQL? I'll show you NoSQL!
Tags: sql, chatgpt, database, nosql
Published: 2023-12-06 06:09:26

A fair bit of warning before we start. What I am demonstrating in this articles and its associated video is for all practical concerns the single largest SQL injection attack surface you've ever seen. If you do this, you need to take every single precautionary step you can to make sure you are *the only* person in the world having access to it. With the disclaimer out of our way, let's get started.

## About GPTs

A GPT is a ChatGPT _"app"_ that allows you to connect it to an API. An API can do anything you wish, including accepting raw SQL, executing it, and returning the result as a raw recordset.

In the video below I've created a GPT that does just that. Combining my API with a little bit of prompt engineering to provide my GPT with an instruction that allows it to transpile English natural language into SQL, results in that I've got a GPT that allows me to write natural language resulting in an SQL that dynamically executes towards my API endpoint, allowing me to use natural language to query my database.

{% embed https://www.youtube.com/watch?v=ACHwU9JM_t8 %}

My API was created in a Magic Cloudlet I've created using AINIRO.IO's Magic Cloud, which is my startup - However, fundamentally you can use anything you wish here that allows you to create an API endpoint accepting SQL as its sole input query argument. I've shamelessly included a link below to our services here.

* [Get a Magic Cloudlet here](https://ainiro.io/)

## The Hyperlambda code

The entire Hyperlambda code required to reproduce what I'm doing can be found below. Create a Hyperlambda file called for instance _"execute-sql.get.hl"_ inside a module of your choosing, and put the following code in it.

```
.arguments
   sql:string
auth.ticket.verify:root,admin
data.connect:magic
   data.select:x:@.arguments/*/sql
   return:x:-/*
```

As my instruction I used the following

> You are an SQL expert, and I will give you instructions that you will transform into an SQL statement that you send to the execute-sql endpoint action. Do not send the SQL before showing me and I confirm with "execute". Once you've executed the SQL, show me the result of the execution.

And voila, I've got a _"natural language NoSQL GPT"_ allowing me to write English to query my database. Pretty cool if you ask me 😎

Yet again, you probably _should not_ do this just because you can - Because in the end, you've just created the single largest SQL injection attack hole in the world. But you *can* do it if you wish ...

I've purposely *not* showed you how to create a module and connect it to a GPT using an OpenAPI specification. Simply because if you're not skilled enough to do that by yourself, you're not experienced enough to do this in the first place - And the temptation for no-coders will simply be too large.
Functional Programming in JavaScript
Tags: webdev, javascript, programming, beginners
Published: 2023-12-06 06:08:25

### Brief Introduction

JavaScript, known for its flexibility, allows us to embrace functional programming, a paradigm that emphasizes the use of functions as the primary building blocks of a program. Let's dive into the core concepts and practices of functional programming.

#### 1. Functions as First-Class Citizens

In JavaScript, functions are first-class citizens, enabling them to be assigned to variables, passed as arguments, or returned from other functions.

```javascript
// Assigning a function to a variable
const greet = (name) => `Hello, ${name}!`;

// Passing a function as an argument
const sayHello = (func, name) => func(name);

console.log(sayHello(greet, 'Alice')); // Output: Hello, Alice!
```
---

#### 2. Embracing Higher-Order Functions

Higher-order functions take other functions as arguments or return them, allowing for powerful abstractions and composability.

```javascript
// Higher-order function example
const multiplier = (factor) => (number) => number * factor;

const double = multiplier(2);
console.log(double(5)); // Output: 10

const triple = multiplier(3);
console.log(triple(5)); // Output: 15
```

---

#### 3. Immutability and Pure Functions

Favoring immutability and pure functions, which produce the same output for the same inputs without side effects, enhances code predictability and readability.

```javascript
// Pure function example
const add = (x, y) => x + y;

// Immutable array manipulation
const numbers = [1, 2, 3];
const doubledNumbers = numbers.map(num => num * 2);
console.log(doubledNumbers); // Output: [2, 4, 6]
```
---

#### 4. Leveraging `map`, `filter`, and `reduce`

Functional programming encourages using higher-order functions like `map`, `filter`, and `reduce` instead of traditional loops for data transformation and processing.

```javascript
// Using map
const numbers = [1, 2, 3];
const doubled = numbers.map(num => num * 2);
console.log(doubled); // Output: [2, 4, 6]

// Using filter
const evenNumbers = numbers.filter(num => num % 2 === 0);
console.log(evenNumbers); // Output: [2]

// Using reduce
const sum = numbers.reduce((acc, curr) => acc + curr, 0);
console.log(sum); // Output: 6
```

---

#### Conclusion

Functional programming in JavaScript offers a paradigm shift, fostering cleaner, more maintainable code by emphasizing higher-order functions, immutability, and pure functions. Incorporating these principles into your codebase unlocks its potential for scalability and readability.

If you are not already, start leveraging these functional programming concepts in your projects to enhance your code quality!

React JS Superpower - Virtual DOM
Tags: webdev, javascript, react, opensource
Published: 2023-12-06 05:48:23



#### The Virtual DOM (VDOM) is a representation of the real DOM in memory. It is a lightweight, tree-like data structure that mirrors the actual DOM tree. When there are changes to the data model, the VDOM is updated instead of the real DOM. This makes updates to the UI much faster, as it only requires updating the VDOM and then reconciling the changes with the real DOM.

Here are some of the reasons why VDOM is faster than real DOM updates:

_**Diffing**_: The VDOM uses a diffing algorithm to efficiently identify the minimum set of changes that need to be made to the real DOM. This avoids the need to re-render the entire DOM tree, which can be expensive.

_**Batch Updates**_: VDOM updates are batched together, so that multiple changes can be applied to the real DOM in a single operation. This further reduces the number of times the real DOM needs to be updated.

_**Selective Updates**_: VDOM updates are only applied to the parts of the real DOM that have actually changed. This is in contrast to direct DOM updates, which can re-render entire sections of the DOM even if they haven't changed.

_**No Reflow or Repaint**_: Updating the VDOM does not trigger reflow or repaint. This means that the browser does not need to recalculate the layout of the page or redraw the pixels on the screen. This can save a significant amount of time, especially for complex UIs.

Overall, the VDOM is a powerful tool that can significantly improve the performance of web applications. By using the VDOM, developers can create more responsive and performant UIs that provide a better user experience.
