How to Upload Files via SFTP in Laravel
Tags: webdev, php, programming, beginners
Published: 2023-12-01 12:04:57

Secure File Transfer Protocol (SFTP) allows secure uploading of files between servers. In Laravel, the phpseclib/phpseclib package facilitates SFTP functionalities.

**Prerequisites**
Before proceeding, ensure:

Laravel is installed and configured.To upload a file via SFTP using Laravel, you can use the phpseclib/phpseclib package, which allows secure file transfers. First, ensure you have this package installed in your Laravel project:

```php
composer require phpseclib/phpseclib
```

**Implementing SFTP Upload in a Route**

```php
use phpseclib\Net\SFTP;


Route::post('/upload-html-file', function () {
    $domain = 'your_domain';
    $username = 'your_username';
    $password = 'your_password';

    $sftp = new SFTP($domain);
    if (!$sftp->login($username, $password)) {
        return response()->json(['message' => 'SFTP connection failed'], 500);
    }

    $localFilePath = public_path('assets/web/theme/html/book_landing_page.html');
    $fileName = pathinfo($localFilePath, PATHINFO_BASENAME);
    $remoteFilePath = '/home/your_username/public_html/' . $fileName;
    if (!file_exists($localFilePath)) {
        return response()->json(['message' => 'Local file not found'], 404);
    }

    if ($sftp->put($remoteFilePath, file_get_contents($localFilePath))) {
        return response()->json(['message' => 'File uploaded successfully']);
    } else {
        return response()->json(['message' => 'File upload failed'], 500);
    }

});

```



I just write this code on api.php as a testing purpose. Do not write code directly on route like this.

Replace $localFilePath with the path to your local HTML file.
Modify $remoteFilePath to define the remote server's desired location.

This code snippet establishes an SFTP connection using Laravel and uploads a specified local HTML file to a defined folder on the remote server.

Note: For production, it's recommended to manage sensitive credentials like usernames and passwords securely, possibly using environment variables.

**Further Enhancements**
For a production-ready solution:

Implement this logic within controllers and services.Securely store credentials using Laravel's environment variables.Communicate with this endpoint from your frontend to trigger file uploads as needed.Now you can securely transfer files using SFTP within your Laravel application!

**Hope it might help. Happy Coding **
Understanding Event Delegation
Tags: javascript, webdev, frontend, interview
Published: 2023-12-01 12:00:29

Event delegation is a technique involving adding event listeners to a parent element instead of adding them to the descendant elements. The listener will fire whenever the event is triggered on the descendant elements due to event bubbling up the DOM. The benefits of this technique are:

- Memory footprint goes down because only one single handler is needed on the parent element, rather than having to attach event handlers on each descendant.


- There is no need to unbind the handler from elements that are removed and to bind the event for new elements.

This is where our journey is going to start for real. First of all, I'll show my initial system design to start building something.

**Initial System Design:**


![Initial System Design](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uvv3n8cvtcwtpqefugmw.png)



It's not anything complex; it's just the way that I see some data trafficking around the project. Here's a brief explanation:

- Torpe Main Page: This is our main page.
- Login: This is a button inside our page that will open a modal.
- Sign Up: This is our registration modal inside the login modal.
- Db1: This is the collection where all data about users is stored.
- Db2: This is the collection where all data about products is stored.
- Db3: This is the collection where all logs about sales are stored.
- CMS: This is our content management system.
- Exclusive OAuth: This is the last one, which explains itself.

As the project progresses, we'll adjust how we design things. But honestly, we just need a simple idea of how things should work before we start coding. So, here's my starting point! The next post will explain how we're setting things up for the project.
azure firewall, to my surprise

i just need a virtual desktop and i found azure virtual desktop which sounds great, becouse:

- it is windows
- pricing doesn't really bother me
- and it's maybe time to give azure a try

so yesterday i signed up and got that $200 credits, and quickly get my first virtual desktop with 16gb ram which i love, and i was tired and sleep, forgot to stop the virtual desktop.

this afternoon, i think i'm already spend maybe 10% of my credits becouse the virtual desktop running almost 20 hour, and to my surprise ....


![Azure firewall](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/dqun4afhfmsa3f510zlm.png)

my virtual desktop didn't run out my credits, it's azure firewall, which i know i set it up yesterday, but really, i think, it's pricing will never blow my mind.

my context:
- i am new to cloud in essence of try it with my own hands, but i know cloud concepts long ago, and almost all article i read about optimizing vm cost
- i don't write this to discredit or say something negative about cloud or azure, i just think it's interesting story
Navigating the Intricacies of "This" and "Self" in Javascript and Python
Tags: python, computerscience, webdev, javascript
Published: 2023-12-01 11:36:09


## Introduction

In this article, we'll delve into the inheritance models of Javascript and Python, focusing on the "this" keyword in Javascript and the "self" reference in Python. We often find these concepts perplexing, especially when transitioning between these languages. Let's demystify them by examining their similarities and differences.

## Understanding Constructor Functions

Before we dive into inheritance, it's crucial to understand constructor functions in both languages. These functions are used to create instances of classes, setting up initial properties and behaviors.

## Inheritance Simplified

Inheritance, a cornerstone of object-oriented programming (OOP), allows us to create subclasses from a superclass. These subclasses inherit properties and methods but can also extend or modify them to suit their specific requirements.

## Python Inheritance Model

Python's inheritance model is structured and traditional, resembling other class-based languages like Java and C++. It employs classes and constructors for inheritance. Key patterns include:

- **Single Inheritance:** Inherits from one parent class.
- **Multiple Inheritance:** Inherits from more than one parent class.
- **Super Function:** Python's `super()` function, akin to JavaScript's `super`, calls methods from the parent class.

Example:
```python
class Cat:
    def __init__(self, color):
        self.color = color

class HouseCat(Cat):
    def __init__(self, color, name):
        super().__init__(color)
        self.name = name
```

## JavaScript Inheritance Model

JavaScript uses a prototypal inheritance model. In a prototype-based language like JavaScript, if a property isn't found in an object, the JavaScript engine searches the object's prototype chain.

- **"This" in JavaScript:** Refers to the current object instance and is a reserved keyword. It's context-dependent and can represent different values based on how it's used.

Example:
```javascript
function Animal(name) {
    this.name = name;
}

Animal.prototype.speak = function () {
    console.log(`${this.name} makes a noise.`);
}
```

- **"Self" in Python:** In Python, `self` represents the instance of the class and is explicitly passed to each instance method. It's not a reserved keyword but a strong convention in Python OOP.

Example:

```python
class Employee:
    def __init__(self, firstname, lastname, salary):
        self.firstname = firstname
        self.lastname = lastname
        self.salary = salary

class Developer(Employee):
    def __init__(self, firstname, lastname, salary, stack, experience):
        super().__init__(firstname, lastname, salary)
        self.stack = stack
        self.experience = experience
```

## Conclusion

Understanding "this" in JavaScript and "self" in Python is pivotal for mastering OOP in these languages. Despite their conceptual similarity as references to the current instance, their usage and the inheritance models of their respective languages present unique features worth comprehending for any developer.

48. Working through Python challenges (Day 46)
Published: 2023-12-01 11:26:40

Let's talk about diving into Python challenges – those mind-bending puzzles that really put your skills to the test. Recently, I’ve been knee-deep in some coursework, tackling a bunch of Python problems. And guess what? The big focus was on those sneaky IF ELSE statements and how they work in real-life situations.

Two challenges in particular made me scratch my head a bit:

**The "Wednesday"**
First up was the "Wednesday" challenge. Simple, right? If it's Wednesday, just shout, "It's Wednesday!" But if it's not, ask the user what day it is and respond with a friendly, "Thanks for letting me know, it is <the input day>." If the submitted word is something else, then my program should display, "That's not a day of the week!".

**The Rocket Fuel**
Then came the "Rocket Fuel" challenge. Picture this: a rocket needs fuel that's 15 times the distance it’s going to cover, but it’s got to have at least 100 liters on board no matter what. Sounds straightforward, but handling different distances turned out to be quite the brain-teaser.

Now, don't get me wrong – these challenges may sound easy-peasy, but they had me stuck here and there. Sometimes, what seems simple on the surface can be a whole different story once you get into the nitty-gritty of coding.

But here’s the thing: while these coding puzzles are fantastic for practicing what you’ve learned, there's this constant struggle I face. I tend to forget stuff, and there's never enough time to tackle them. Life's always throwing something else my way – work, chores, you name it. That’s why I'm pinning my hopes on the upcoming Christmas and New Year holidays. I’m crossing my fingers for some quality time to really dig into these challenges.

Juggling work, home stuff, and taking care of myself often means these coding puzzles get pushed to the back burner. But you know what? I'm determined to level up my Python game. The holidays are my chance to dive deep into Python, with no distractions stealing my focus (hopefully!).

These challenges aren’t just about coding—they’re about pushing through obstacles and coming out stronger. They teach you a whole lot about sticking with something, even when it gets tough. I’m ready to take them on and come out on the other side, a better coder!

Remember, the journey to mastering something isn’t always a smooth ride, but it’s the bumps along the way that make it worth it.

Time: 10:30 PM. Warm day today. Waiting for the midnight rain. Tomorrow is my 4-hour LIVE class.
