## Introduction
Recoil has gained traction as a state management library for React. However, there are various methods to persist its state. In this article, we'll explore how to efficiently persist Recoil's state using `react-native-mmkv`, a fast key-value storage.

## Installing Necessary Packages

First, let's install the required packages:

```bash
yarn add recoil react-native-mmkv
```

Then, link the native part of `react-native-mmkv`:

```bash
expo install react-native-mmkv
```

## Creating a Persistence Helper for Recoil

Next, we'll create a helper function to persist the state of Recoil's atoms and selectors using `react-native-mmkv`.

```typescript
import MMKV from 'react-native-mmkv';
import { atom, DefaultValue } from 'recoil';

export const persistentAtom = <T>(key: string, defaultVal: T) => {
  return atom<T>({
    key,
    default: defaultVal,
    effects_UNSTABLE: [
      ({ setSelf, onSet }) => {
        const savedValue = MMKV.getString(key);

        if (savedValue != null) {
          setSelf(JSON.parse(savedValue));
        }

        onSet((newValue) => {
          if (newValue instanceof DefaultValue) {
            MMKV.delete(key);
          } else {
            MMKV.set(key, JSON.stringify(newValue));
          }
        });
      },
    ],
  });
};
```

## Using the Persistent Atom

Now, let's create a persisted atom using the helper function:

```typescript
import { persistentAtom } from './path-to-your-helper';

export const userState = persistentAtom('userState', {
  name: '',
  age: 0,
});
```

## Using in Your Application

You can use this persisted atom in your application just like any regular Recoil atom:

```typescript
import { useRecoilState } from 'recoil';
import { userState } from './path-to-your-atom';

const UserInfo = () => {
  const [user, setUser] = useRecoilState(userState);

  return (
    <View>
      <Text>Name: {user.name}</Text>
      <Text>Age: {user.age}</Text>
    </View>
  );
};
```

## Conclusion

Combining Recoil with react-native-mmkv allows for efficient state persistence in React Native applications. This combination is ideal for maintaining application performance while securely storing user data.

      <Button title="Open Bottom Sheet" onPress={handleOpenSheet} />
      <BottomSheet
        ref={bottomSheetRef}
        index={0}
        snapPoints={['25%', '50%', '75%']}
      >
        <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
          <Text>This is the content of the Bottom Sheet</Text>

_**sample code:**_

```
import React from "react";
import {Helmet} from "react-helmet";
 
class Application extends React.Component {
  render () {
    return (
        <div className="application">
            <Helmet>
                <meta charSet="utf-8" />
                <title>My Title</title>
                <link rel="canonical" href="http://mysite.com/example" />
            </Helmet>
            ...
        </div>
    );
  }
};
```

Dealing with too many tabs
Tags: productivity, beginners, tips, organization
Published: 2023-08-24 06:43:11

Are You also the kind of person who typically has 100+ tabs opened at any given time?

First I started putting everything in bookmarks.

As the mess shifted from the tabs to bookmarks, I started creating folders of bookmarks.

Then I reorganized the bookmark folders hierarchically and recursively.

Avoided "misc" folder like devil.

Sometimes I create some temp folder for stuff, which I'm planing to delete in the future. This could be an investigation, ticket-related stuff, gathering knowledge about a particular topic, etc. After job's done, one button click and clean.

Saves time for the daily used stuff. 
Saves a lot of time for the something I need once a year!

And don't forget to back up the bookmarks time to time:
Chrome: bookmarks -> bookmark manager -> (three dots in the corner) -> export bookmarks
Firefox: bookmarks -> manage bookmarks -> import and backup -> export bookmarks to HTML
Bad Practices In JavaScript
Tags: webdev, javascript, beginners, programming
Published: 2023-08-24 06:42:53


Certainly, here are some common bad practices in JavaScript that you should avoid to write clean, maintainable, and efficient code:

1. Using Global Variables: Relying heavily on global variables can lead to naming conflicts, unintended data modification, and difficulty in debugging and maintaining code.

```javascript
// Global variable
var globalCounter = 0;

function incrementCounter() {
    globalCounter++;
    console.log(globalCounter);
}

// Avoid global variables
function incrementCounter(counter) {
    counter++;
    console.log(counter);
    return counter;
}

let localCounter = 0;
localCounter = incrementCounter(localCounter);


```
2. Not Using Proper Variable Declaration: Always declare variables with `var`, `let`, or `const` to avoid polluting the global scope and to ensure proper scoping.

```javascript
//Bad Practice: Using var instead of const/let
var count = 0;


//Better Practice
let count = 0; // Use let or const based on reassignment
const MAX_COUNT = 10; // Use const for constants

```

3. Not Handling Errors: Failing to handle errors can lead to unexpected crashes or issues in your application. Always use try-catch blocks or promises to handle potential errors gracefully.

```javascript
// Not handling errors
try {
    // Code that might throw an error
} catch (error) {
    // No error handling
}

// Handling errors
try {
    // Code that might throw an error
} catch (error) {
    console.error("An error occurred:", error);
}


```
4. Callback Hell: Nesting callbacks excessively (also known as callback hell) can make code difficult to read and maintain. Consider using promises, async/await, or libraries like `async.js` to manage asynchronous operations more elegantly.

```javascript
asyncFunction1(() => {
    asyncFunction2(() => {
        asyncFunction3(() => {
            // More nested callbacks
        });
    });
});

//Better Practice

asyncFunction1()
    .then(() => asyncFunction2())
    .then(() => asyncFunction3())
    .then(() => {
        // Code after all async operations
    })
    .catch((error) => {
        console.error("An error occurred:", error);
    });

```
5. Not Using "strict" Mode: Not using strict mode can lead to subtle bugs. Enable strict mode by adding "use strict"; at the beginning of your script or function.

6.Ignoring Semicolons: While JavaScript allows optional semicolons, it's a good practice to include them. Omitting semicolons can lead to unexpected behavior due to automatic semicolon insertion

```javascript
const message = "Hello"
console.log(message)

//Better Practice
const message = "Hello";
console.log(message);

```

7.Using == Instead of ===: Always use strict equality (===) instead of loose equality (==) to avoid type coercion and unexpected comparison results.

```javascript
if (value == 10) {
    // This could lead to unexpected type coercion
}


if (value === 10) {
    // Use strict equality to avoid type coercion
}


```

Often when you install [zoom](https://zoom.us) in linux you would have encountered broken install issue. Here is a function to save you from installing and keeping it updated:

```
#!/bin/bash
update_zoom() {
    curl -LO https://zoom.us/client/latest/zoom_amd64.deb
    package_names=$(dpkg --info zoom_amd64.deb | grep -oP 'Depends: \K.*' | sed 's/ ([^)]*)//g' | tr -d ',')
    sudo apt install -y $package_names
    sudo dpkg -i zoom_amd64.deb
    rm zoom_amd64.deb
    echo "Zoom has been installed..."
}
alias update_zoom="update_zoom"
```
Save the script into a file named `update_zoom.sh` and save it in `$HOME/scripts` directory.

Const Assertion
Tags: typescript, angular, frontend, developer
Published: 2023-08-24 05:49:58

Strive to use const assertion (as const):

1. type is narrowed

2. object gets readonly properties

3. array becomes readonly tuple

let's see an example:

```
// ❌ Avoid declaring constants without const assertion
const BASE_LOCATION = { x: 50, y: 130 }; // Type { x: number; y: number; }
BASE_LOCATION.x = 10;
const BASE_LOCATION = [50, 130]; // Type number[]
BASE_LOCATION.push(10);

// ✅ Use const assertion
const BASE_LOCATION = { x: 50, y: 130 } as const; // Type '{ readonly x: 50; readonly y: 130; }'
const BASE_LOCATION = [50, 130] as const; // Type 'readonly [10, 20]'
