Syntax errors can sometimes be intimidating, here I will explain how I created better error messages for my code editor project.

As part of my [Koduj project](https://koduj.org/), where I teach JavaScript with a creative coding course, I've created a prototype of a code editor that uses [P5.js graphic library](https://p5js.org/).

Normally when you made a syntax error in JavaScript you have a runtime error that doesn't say much about the error itself and you need to ask for help to decipher the error.

An example is this code:

```javascript
function f(x)
   return 2 * x + 3;
}
```

That should plot a linear function. I use this example in the second lesson about functions (the first lesson is a lecture about how the computer works).

Normal error from JavaScript looks like this:

```
Uncaught SyntaxError: Unexpected token 'return'
```

By an error in my editor look like this:

```
Unexpected token, expected "{" (2:5)
  1 | function f(x)
> 2 |     return 2 * x + 1;
    |     ^
  3 | }
```

As you can see the error is obvious now, the missing open curly brace.

So how I did do this? I need to say that it's by accident. I use [Prettier](https://prettier.io/) to format the code for the user, I do that only when the user presses the button. But luckily I've noticed that Prettier error messages are much better than the ones from the JavaScript parser that I was using (right now I use [espree](https://github.com/eslint/espree)) and of course the JavaScript runtime. So I've added formatting of code on every change user made and saved it in the main state. When the user clicks format I just use what is in the state. But what I now have is much more user-friendly error messages.

If you want to see the playground I've built here is the link:

[https://p5.javascript.org.pl/energetic-potential](https://p5.javascript.org.pl/energetic-potential?include=coord.js&main=plot.js&base=fn.js)

Note that there are no login and the code use the [Firepad editor](https://firepad.io/), [Firebase](https://firebase.google.com/) collaborative editor so more than one user can edit the code at once. This is just a prototype, the next version if it will be created will have proper authentication and authorization.

Sequelize Migration
Tags: sequelize, node, sql, database
Published: 2023-05-27 09:35:13

While working with SQL databases and especially when the application is in the production stage. migration helps to change the current state of the database to another state, and vice versa like Github version control.

### Let's start with all the useful commands
<br>

There are some prerequisites to use migration in the project.

* You must have initiated the node project with the npm init command in your project directory.
* Install Sequelze npm package
```
npm i sequelize
```
In the latest version of sequelize we don't need sequelize-cli package. we can run migration commands by only installing sequelize package.

That is it, you are good to go.

## First command after Installing the npm package
``` bash
npx sequelize init
```
* This will initiate migration setup and create 4 directories in your project structure
1 config
2 migrations
3 models
4 seeders
![All Sequelize files](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0ln34nigibowmy08b8pk.png)

* However we can create this setup for individual directories as well.
``` bash
npx sequelize init:config        // Create config folder and config.json
npx sequelize init:migrations    // Create Migration folder 
npx sequelize init:seeders       // Create seeders folder             
npx sequelize init:models        // Create a model folder and index.js to handle all the models           
```
### Custom configuration
* We can change the path of all the folders according to the needs of our project structure.
* For that we first need to create ".sequelizerc" file in the root directory of the project and set up our configuration of Sequelize in the newly created file as below given example.
![custom sequelize configration](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xsc9couojmw7z6yjwit7.png)

## Create migration files and run migrations
After setting up Sequelize in the project we create migration for our database models with given commands.

``` bash
// This will create the new migration file
npx sequelize migration:generate --name=creat-user        

// Apply all the pending database migrations
npx sequelize db:migrate

// Apply migration of individual file
npx sequelize db:migrate --to 20230527090813-create-user.js
```

* Undo migrations
``` bash
// undo migration of specific migration file
npx sequelize db:migrate:undo --name <file_name>
```

## Create seeder files and run seeders
``` bash
// Show the status of current seeder files
npx sequelize db:migrate:status
```
* create a seeder file
``` bash
// create seeder file
sequelize seed:generate --name=users
```
* Run seeder file
``` bash
// Run all the seeder files make sure you run only once
npx sequelize db:seed:all

// Run only spesefic seeder file
sequelize db:seed --seed 20230527092604-users.js
```

I'm happy to share the latest library I've been working on.

It is called CurrencyFX.

Let's check it out 😆

## Introduction

CurrencyFX is a PHP Library that helps you retrieve FX Rates from multiple online services, batteries-included 🔋🔋🔋

Repository: https://github.com/shipsaas/currency-fx

Requirement: PHP 8.1+
- Additionally, Laravel 10 (for Laravel auto integration)

100% tested and covered under Unit, Integration & E2E tests (assert against the real services)

## Installation

```bash
composer require shipsaas/currency-fx

# (Optional) For Laravel users
php artisan vendor:publish --tag=currency-fx-configs
```

## Supporting Services / Batteries
- https://exchangeratesapi.io/
- https://exchangerate.host/
- https://fixer.io/
- https://currencylayer.com/
- https://www.currencycloud.com/

## Usage

Simply initialize the class with the required parameters (which are the API Key, Credentials). And it is ready to use in no time.

```php
$service = new CurrencyCloudService($host, $loginId, $apiKey);
$rateResponse = $service->getRates('USD', 'SGD');

if (!$rateResponse->isOk()) {
    // failed to get the rate from third party service
    // do something here
}

$rate = $rateResponse->getOkResult()->rate; // float (1.4xxx)
```

## Laravel Usage

(Please add the needful ENVs before using, check out the `currency-fx.php` for more info)

```php
use CurrencyFX\Services\CurrencyLayerService;
use CurrencyFX\Services\ExchangerRatesApiIoService;

// use the global "app"
app(CurrencyLayerService::class)->getRates('USD', 'EUR');

// DI
class TransferService
{
    public function __construct(
        private ExchangerRatesApiIoService $rateService
    ) {
    }

    public function transfer(): TransferResult
    {
        $rateRes = $this->rateService->getRates('EUR', 'GBP');
        if ($rateRes->isError()) {
            return TransferResult::error(...);
        }

        $rate = $rateRes->getOkResult()->rate;
    }
}
```

Abstraktsiya(abstraction) va Interface
Published: 2023-05-27 09:04:38

**Abstraction** foydalanuvchiga ma'lumotlarning faqatgina muhim qismini ko'rsatib, qolgan ma'lumotlarni yashirish jarayoni hisoblanadi. 
Abstraksiyani 2 xil usulda amalga oshirsa bo'ladi:
1. **Abstract class**(abstrakt sinf)
2. **Interface**(Interfeys)

## Abstract class
Abstract class - bu imkoniyati cheklangan class hisoblanib, undan obyekt olib bo'lmaydi va ichida hech qanday _implementation_ bo'lmaydi. Undan foydanalish uchun undan voris olish lozim bo'ladi. 

## Abstract method 
Abstract method - faqatgina abstract class ichida ishlaydi lekin uning tanasi bo'lmaydi. 

> Abstract class ichidagi abstrakt metodlarni voris classlar `override` qilishga majbur. Agarda override qilinmasa, syntax xato hisoblanadi. 

```c#

using System; 
​
// abstrakt class 'Hayvonlar' 
public abstract class Hayvonlar 
{
    // abstrakt metod 'Ovoz()'
    public abstract void Ovoz();
}
​
// class 'Hayvonlar' dan olingan  voris class 'Sigir'
public class Sigir : Hayvonlar 
{
    // Qayta ishlangan 'Ovoz()' metodi
    public override void Ovoz() 
    { 
        Console.WriteLine("Moo");
    }
}
​
class Program
{
    static void Main(string[] args)
    {
         // Sigir obyektini yaratish
         Sigir sigir_obj = new Sigir();
         
         // abstrakt metodni chaqirish
         sigir_obj.Ovoz();
     }
 }
```

## Interface
Interface - abstractga erishishning boshqa usuli hisoblanadi va tanasi faqat abstract methodlar va propertylardan tashkil topgan bo'ladi. Interfacelar ichidagi methodlar va propertylarni access modifier(private, public, protected)lari bo'lmaydi, chunki by default barchasi public hisoblanadi. 
C#da interfacelar oldidan doim **"I"** yoziladi. 

```c#
interface IAnimal 
{
  void animalSound(); // interface method (does not have a body)
  void run(); // interface method (does not have a body)
}
```

Xulosa qilib aytganda:

> - Classlar ichida qandaydur data, property va methodlar saqlaydi, shuning uchun u abstract class bo'ladimi yoki oddiy classmi, ulardan voris olinadi.
> - Abstract method ichida `static` yoki `virtual` modifierlarini ishlatish xato hisoblanadi. Chunki uningsiz ham abstractdan voris olinganda tabiiy ravishda override qilinishi kerak.  
> - Interfacelar tarkibi faqatgina declarationdan iborat bo'lganligi sababli ular implement qilinadi.
> - Interfacelar ko'pincha **contract** deb ham nomlanadi.
Simplify Your Documentation Workflow with MkDocs: A Markdown-based Alternative to Sphinx
Tags: documentation, opensource, python, tutorial
Published: 2023-05-27 08:30:31

## Introduction:
Documentation is an essential aspect of software development, enabling developers to communicate effectively with users and fellow developers. Sphinx and MkDocs are two popular documentation generators in the Python ecosystem. While Sphinx has been the go-to choice for many, MkDocs offers a simpler and more streamlined approach. In this article, we will explore why MkDocs, with its markdown-based structure, is easier to use than Sphinx.

## Main Difference:
Sphinx has a steep learing curve as you use restructure and all but mkdocs does the same thing with Markdown, which makes it easier to add preadded documentation which is in Markdown 

## Markdown: A Familiar Syntax:
One of the significant advantages of MkDocs over Sphinx is its use of Markdown. Markdown is a lightweight markup language that is easy to learn and read, making it a preferred choice for documentation writing. With Markdown, you can write your documentation in a more natural and straightforward manner without worrying about complex syntax and markup rules.

## Simple Configuration:
MkDocs boasts a simple configuration structure. With just a single configuration file, you can customize your documentation project effortlessly. MkDocs configuration uses the YAML format, which is human-readable and intuitive. By contrast, Sphinx has a more intricate configuration system, requiring you to learn and understand its extensive set of directives and options.

## Rapid Development and Live Preview:
MkDocs offers a built-in development server that provides a live preview of your documentation as you write it. This feature allows you to see the changes you make in real-time, saving you the hassle of repeatedly building your documentation. Sphinx, on the other hand, requires you to rebuild the documentation every time you want to view the changes, which can slow down your development workflow.

## Extensive Theming and Plugin Ecosystem:
MkDocs has a vibrant ecosystem of themes and plugins, allowing you to customize and enhance your documentation effortlessly. With a wide range of themes available, you can easily find one that matches your project's aesthetics. Additionally, the plugin system enables you to extend the functionality of MkDocs to suit your specific needs. While Sphinx also provides theming and plugin options, the simplicity and ease of use offered by MkDocs make it a more accessible choice for developers.

## Conclusion:
While Sphinx has long been the go-to documentation generator in the Python community, [MkDocs ](https://www.mkdocs.org/user-guide/writing-your-docs/)offers a simpler and more straightforward alternative. With its use of Markdown, intuitive configuration, live preview, and extensive theming/plugin ecosystem, MkDocs simplifies the documentation workflow for developers. Whether you're a beginner or an experienced developer, MkDocs can help you create professional-looking documentation with ease. So why not give it a try and see how it can enhance your documentation process?
How to Solve Unexpected Margins in HTML and CSS
Tags: webdev, beginners, html, css
Published: 2023-05-27 08:29:36

## Introduction

While working on web development, have you ever encountered unexpected margins appearing and disrupting your layout? How do you handle such a situation? Today, I'm going to introduce a handy CSS trick for addressing this kind of issue.

## Margin Issues and How to Deal With Them

Firstly, take a look at the image below. It's a webpage layout displaying news articles, but you can see some margin on the right side.

![sample2](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xsyjuw25amhbjt99eh2x.jpg)

This margin is caused by certain elements spreading beyond the width of the page. But how can we identify which element is causing the problem?

The solution is to add an outline to all elements. The following image shows the result.

![sample3](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/edeussahmnm5a6z8rz0x.jpg)

This red outline is applied with the following CSS code:
```css
*{
    outline: 1px solid red;
}
```

This code adds an outline to all elements on the page. This way, it's easy to see which elements are overflowing on the right side.


## Conclusion
This CSS technique is a great tool for identifying the cause of unexpected margins in your layout. Once you've identified the problematic element, you can solve the issue by adjusting the styling for that element.

However, remember that this CSS snippet is a debugging tool and should be removed after debugging is complete.

So, that's one way to detect and deal with unexpected margins in HTML and CSS. Remember this technique, and you'll be able to quickly handle margin issues when they arise. Enjoy your web development journey!
