Callback Hell In JavaScript
Tags: webdev, javascript, beginners, programming
Published: 2024-06-10 09:32:20

**Callback Hell In JavaScript :**

✍  When a function is passed as an argument to another function, it becomes a callback function. This process continues and there are many callbacks inside another's Callback function. The code grows  horizontally instead of vertically .That mechanism is known as callback hell.

Callback Hell (Pyramid of Doom) , occurs in asynchronous programming when multiple callbacks are nested within one another . This pattern emerges when each asynchronous operation requires a callback function, and these callbacks contain further asynchronous operations that also need callbacks.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nvzza7u9h9agv2mrr266.png)

**✍ Explanation :**

**_createOrder Function:_**

- When the createOrder function is called, a callback function is passed into it.
- Example: createOrder(() => {}).
- Inside createOrder, this callback function is executed after completing the createOrder operation.
- By using this callback function, you can call paymentOfOrder inside the callback after createOrder is done.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/itjmeq5uoor66e7yo1ua.png)

**_paymentOfOrder Function:_**

- When the paymentOfOrder function is called, a callback function is passed into it.
- Example: paymentOfOrder(() => {}).
- Inside paymentOfOrder, this callback function is executed after completing the payment operation.
- By using this callback function, you can call orderSummary inside the callback after paymentOfOrder is done.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bt1lrxt8gwa8759r5d04.png)

_**orderSummary Function:**_

- When the orderSummary function is called, a callback function is passed into it.
- Example: orderSummary(() => {}).
- Inside orderSummary, this callback function is executed after completing the summary operation.
- By using this callback function, you can call updateWallet inside the callback after orderSummary is done.

**_Complete Flow with Explanations_**
Here’s the complete flow with these explanations applied:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7znybgnq9nmmrspv50tm.png)

This expanded explanation should clarify how each function's callback is used to invoke the next function in the sequence, demonstrating the flow of execution and how callback functions are passed and executed at each step. 

This nesting of callbacks is what leads to callback hell as it makes the code harder to read and maintain, especially as the number of nested operations grows.

Avoid callback hell, consider refactoring the code using Promises or async/await for better readability and maintainability, as previously demonstrated.

laravel reverb installation process and setup with common mistakes
Tags: laravel, reverb, broadcasting, realtime
Published: 2024-06-10 09:16:19


Installing and setting up Reverb in a Laravel project involves several steps. Reverb is a package that allows for a quick implementation of real-time broadcasting features in a Laravel application. Here's a step-by-step guide:

## Prerequisites

- Laravel Installation: Ensure you have a Laravel project set up.
- Composer: Make sure Composer is installed on your system.
- Node.js and npm: These are required for front-end dependencies.
- Step 1: Install Laravel Echo and Pusher
- Install Laravel Echo: Laravel Echo is a JavaScript library that makes it easy to work with WebSockets in Laravel.
- Install Pusher: Pusher is a WebSocket service that is commonly used with Laravel Echo.

## Step 1: Install Laravel Reverb. You may install Reverb using the install:broadcasting Artisan command:

```
php artisan install:broadcasting
```

Behind the scenes, the `install:broadcasting` Artisan command will run the `reverb:install` command, which will install Reverb with a sensible set of default configuration options. If you would like to make any configuration changes, you may do so by updating Reverb's environment variables or by updating the config/reverb.php configuration file.

You may define these credentials using the following environment variables:

```
REVERB_APP_ID=my-app-id
REVERB_APP_KEY=my-app-key
REVERB_APP_SECRET=my-app-secret
```

If you are using auth but no api then you dont have to use any other extra configuration but there are several configurations for some api authentication system. Lets configure for those 

## Sanctum or Passport
if you are using sanctum api authentication then you have to set some things while using the ECHO 

```
import Echo from 'laravel-echo';
 
import Pusher from 'pusher-js';
window.Pusher = Pusher;
 
window.Echo = new Echo({
    broadcaster: 'reverb',
    key: import.meta.env.VITE_REVERB_APP_KEY,
    wsHost: import.meta.env.VITE_REVERB_HOST,
    wsPort: import.meta.env.VITE_REVERB_PORT,
    wssPort: import.meta.env.VITE_REVERB_PORT,
    forceTLS: (import.meta.env.VITE_REVERB_SCHEME ?? 'https') === 'https',
    enabledTransports: ['ws', 'wss'],
auth: {
        headers: {
            Authorization: useCookie('accessToken').value,  // If using token-based auth
        },
    },

});
```


as you can see i have added auth param in the echo. if you dont use this for private channel it will give you error. So you need to pass the authentication token. cause by default the route middleware is `auth`

and also you need to add a special thing on the `channel.php` file without that your private channel will not work for token based authentication 

```
Broadcast::routes(['middleware' => ['auth:sanctum']]);
```
if you use other token based authentication then add that middleware here in `channel.php`


This will solve the 403 forbidden issue for private channel

How to use react-icons in React with TypeScript
Tags: react, typescript, webdev, tutorial
Published: 2024-06-10 08:29:01

Hello everyone..!

This is for the all learners who wants to try and use react-icons which is also an open source and free icons library package to use. 

Lets start implementing it. 
**First and foremost** thing to do is, install the npm package by running `npm i react-icons` or `npm install react-icons`.

**Secondly,** you have to install prop-types using `npm i prop-types` as TypeScript doesn't like the missing props validation and frankly this is the best practice to follow as well. 

Once that is install try to import that into your parent component where you want to use it. To do so, use import statement like `import {FaDev} from "react-icons"`.

Check out [react-icons page](https://react-icons.github.io/react-icons/search/#q=)

**Next** import Icons Types which is provided by react-icons it self to work with Typescript else you might get an error as soon as you start using it normally like we do in react-JavaScript. Use `import {IconType } from "react-icons"`  to import types. 

Now we have done the basic setup its time to create a reusable component for using this, which is more common approach according to me. To do so, start by creating the component you can create anywhere but more common convention is to keep these inside components/utils or components/ui folder depends on how is your folder structure, but feel free to adopt as per your need. 

Below is the code which you can copy paste. 

```import { IconType } from "react-icons";
import PropTypes from "prop-types";
interface IconStar {
  icon: IconType;
}
const IconComponent: React.FC<IconStar> = ({ icon: Icon }) => {
  return <Icon />;
};
IconComponent.propTypes = {
  icon:  PropTypes.func.isRequired,
};
export default IconComponent;```

**Woah...!** that's it now you are ready to use it just like a normal react component  and all the error's you see would be gone. 

`<IconComponent icon={FaDev}/>`
