Implementing the Repository Pattern in Go (Golang)
Tags: go, designpatterns, backend, programming
Published: 2023-09-09 16:05:16

The Repository Pattern is a commonly used pattern in software architecture that abstracts the data access logic for an application. It promotes a cleaner separation of concerns, making the application more maintainable, scalable, and testable.

When applied to Go (or "Golang"), the Repository Pattern provides a straightforward way to abstract the access to your data source, which could be a database, a web service, or even a file system. Here's a brief overview of how you can implement it:

## 1. Define your domain model:
```go
// models/user.go
package models

type User struct {
    ID    int    `json:"id"`
    Name  string `json:"name"`
}
```

## 2. Define the Repository interface:
This interface will outline the methods that your repository must implement.

```go
// repository/user_repository.go
package repository

import "your_package_path/models"

type UserRepository interface {
    GetAll() ([]models.User, error)
    GetByID(id int) (models.User, error)
    Save(user models.User) error
    Delete(id int) error
}
```

## 3. Implement the Repository:
For this example, let's assume we're using a simple in-memory store.

```go
// repository/memory/user_repository_impl.go
package memory

import (
    "your_package_path/models"
    "your_package_path/repository"
)

type UserRepositoryMemory struct {
    users []models.User
}

func NewUserRepositoryMemory() repository.UserRepository {
    return &UserRepositoryMemory{
        users: []models.User{},
    }
}

func (r *UserRepositoryMemory) GetAll() ([]models.User, error) {
    return r.users, nil
}

func (r *UserRepositoryMemory) GetByID(id int) (models.User, error) {
    for _, user := range r.users {
        if user.ID == id {
            return user, nil
        }
    }
    return models.User{}, errors.New("User not found")
}

func (r *UserRepositoryMemory) Save(user models.User) error {
    r.users = append(r.users, user)
    return nil
}

func (r *UserRepositoryMemory) Delete(id int) error {
    for index, user := range r.users {
        if user.ID == id {
            r.users = append(r.users[:index], r.users[index+1:]...)
            return nil
        }
    }
    return errors.New("User not found")
}
```

## 4. Use the Repository in your services or application logic:

```go
package main

import (
    "your_package_path/models"
    "your_package_path/repository"
    "your_package_path/repository/memory"
)

func main() {
    // Using the in-memory implementation
    repo := memory.NewUserRepositoryMemory()

    user := models.User{
        ID:   1,
        Name: "John Doe",
    }

    repo.Save(user)

    users, _ := repo.GetAll()
    for _, user := range users {
        fmt.Println(user.Name)
    }
}
```
With this pattern in place, you can easily swap out your in-memory implementation for, say, a PostgreSQL or a MongoDB implementation without changing your main application logic.
I Lost my job, spent months building something like Pinterest for links, now has 900+ users
Tags: webdev, javascript, discuss
Published: 2023-09-09 15:58:28

Hey builder, here's my story of building [linkcollect.io](https://linkcollect.io/) , and how it grew to around 900 (almost 1k 🤩) users. 

I was working at an early stage startup till march 2023, things went otherwise. I lost my job (fired) because the company kinda went bankrupt. 


Just after this happened, i started thinking of building some side projects and that's where i got this idea of building a resource aggregator because lots of people were asking me how did i learn software development and stuff again and again and i wanted to be able to just share them the resources i used. So i thought of building a tool that does this.



I went ahead, and started building [linkcollect.io](https://linkcollect.io). the V1 MVP got ready within 3-4 weeks, which at that time was just a browser extension that helped people save and organise resources and links in folder, just like any other bookmark manager. 


![Me launching linkcollect on twitter](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/eoent50dmqoxtbp0zz3y.png)


V1 launch did fine, i built it and launched on twitter, Instagram and LinkedIn. I got around 200 people using it after 2-3 weeks of the launch. 

v2 launch was pretty good, before the launch we were at around 490 something users, but as soon as we launched and started posting everywhere we could. the user base kind of started going, which means now we had more than enough users to collect feedback from to iterate for the next version. 

But what i wanted to build, initially when i started is live and the fact the people are using it, and it's helping them a lot (from feedback) is amazing.

Slot Maxwin : Situs Slot Gacor Terpercaya Gampang Menang Hari Ini
Tags: slotmaxwin, slotonline, slot88, slotgacormaxwin
Published: 2023-09-09 15:54:23

[Slot maxwin](https://seomaster303.my.id/-/slot-maxwin/) adalah istilah yang digunakan dalam industri perjudian untuk merujuk pada jumlah maksimum kemenangan yang dapat dicapai dalam satu putaran atau sesi bermain pada suatu mesin slot tertentu. Setiap mesin slot memiliki nilai maxwin yang ditentukan oleh penyedia permainan atau kasino yang mengoperasikannya.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2eug658htphmx0dw43d1.png)


Berikut adalah beberapa hal yang perlu Anda ketahui tentang [Slot Maxwin](https://seomaster303.my.id/-/slot-maxwin/):

Penentuan oleh Penyedia Permainan: Maxwin pada suatu mesin slot ditentukan oleh desain dan aturan permainan yang dibuat oleh penyedia permainan. Ini termasuk kombinasi simbol dan nilai taruhan maksimum yang dapat menghasilkan maxwin.

Variabilitas Maxwin: Maxwin dapat sangat bervariasi antara mesin slot yang berbeda. Beberapa mesin slot menawarkan maxwin yang lebih kecil, sementara yang lain memiliki potensi maxwin yang jauh lebih tinggi, terutama pada mesin slot dengan jackpot progresif.

Pentingnya Tabel Pembayaran: Untuk mengetahui berapa maxwin pada suatu mesin slot, Anda perlu memeriksa tabel pembayaran permainan. Tabel ini akan menunjukkan kombinasi simbol yang menghasilkan kemenangan tertinggi.

Peluang: Meskipun maxwin dapat menggiurkan, penting untuk diingat bahwa peluang untuk mencapai jumlah ini biasanya sangat rendah. Mesin slot didasarkan pada RNG (Random Number Generator) yang membuat hasil putaran acak.

Bijak dalam Bermain: Bermain mesin slot adalah bentuk perjudian, dan selalu penting untuk bermain dengan bijak. Tetapkan batas bermain yang rasional, dan jangan melebihi anggaran Anda. Maxwin besar adalah hal yang jarang terjadi, dan sebagian besar pemain tidak akan mencapainya.

Hiburan: Mesin slot sebaiknya dilihat sebagai bentuk hiburan, bukan sebagai cara untuk menghasilkan uang. Anda seharusnya menikmati pengalaman bermain tanpa terlalu terfokus pada maxwin.

Ingatlah bahwa maxwin adalah bagian dari daya tarik mesin slot, tetapi tidak ada jaminan bahwa Anda akan mencapainya saat bermain. Penting untuk selalu bermain dengan tanggung jawab dan memahami risiko perjudian.
Computed Properties 🤙
Tags: vue, javascript, webdev, frontend
Published: 2023-09-09 15:37:37


## Overview
Vue uses special properties called "Computed properties" to help apps perform best and avoid boring code repetition for developers.
In this article you will discover the features behind this incredible properties.
Let's start 🤙🏻

---

## What are Computed Properties?
A Computed property is a variable that contains the return value of a function.
What differentiates this property from simple JavaScript variables are mainly three factors:

- The return value depends on other external variables
- After the calculation is performed, the value is cached
- It's possible reuse this prop in all part of app

```js
<script setup>
import { reactive, computed } from "vue";

const wizard = reactive({
  name: "Harry Potter",
  animagus: false,
});

const isAnimagus = computed(() => wizard.animagus ? "Yes" : "No");
</script>

<template>
  <p>Is {{ wizard.name }} Animagus?</p>
  <span>{{ isAnimagus }}</span>
</template>
```


In the example above we can see how to declare and use a **Computed property**:
1. import `computed` from Vue library: this is a native API of framework that you must use for declare a Computed Property
2. `computed` takes a callback as a parameter and this callback **MUST** always have a return statement
3. last step binding the variable in HTML template

---

## Computed vs Methods

The Computed property is not dissimilar to the method, in fact it is possible use the method approach and obtain the same result. So what is the difference?

Computed properties are cached based on their reactive dependencies, meaning they are only recomputed when dependencies change, while methods are always calculated.
For this reason, it's recommended use when it's possible.

---

## Writable Computed

By default, Computed properties are getter-only, but it's possible a declare a setter and make Computed a "Writable Computed".

```js
<script setup>
import { ref, computed } from 'vue'

const name = ref('Harry')
const surname = ref('Potter')

const fullName = computed({
  get() {
    return name.value + ' ' + surname.value
  },
  set(newValue) {
    [name.value, surname.value] = newValue.toUpperCase()
  }
})
</script>
```
This approach is not very common, but there're some rare cases that it may be necessary.

---

## Avoid mutating computed value

The returned value from a computed property is derived state. For this reason you don't need to directly modify the return value, it wouldn't make sense!
Computed Properties are reactive and are calculated whenever their dependencies change.

---

## Conclusion
Computed properties are a very important feature of Vue and allow the development of high-performance applications with lower computational costs.
Therefore they are strongly recommended.
Happy coding!✨

Algorithm To Create Phone Number "Codewars"
Tags: javascript, node, algorithms, programming
Published: 2023-09-09 15:17:27

Write a function that accepts an array of 10 integers (between 0 and 9), that returns a string of those numbers in the form of a phone number.
Don't forget the space after the closing parentheses!
E.g:
Given ([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]) 
It should return "(123) 456-7890"

Algorithm.

Step-1 - Use an if statement to ensure that the length of the array is 10 digits.

Step-2 - Using the slice() method in javascript we need to divide the array into three parts based on the format given to us. the first part will hold the first 3 digits, the second part will hold the next three numbers and the last part will hold the last four digits.

step-3 - concatenate the three parts together into a new variable. Don't forget to add the parentheses, the space after the closing parentheses and the dash.

Step-4 - return your variable  

```js
function createPhoneNumber(numbers) {
    // Check if the numbers array has exactly 10 digits.
    if (numbers.length !== 10) {
        return "Invalid input.";
    }
    // Using slice() method to get the first 3 second 3 and last 4
    let firstPart = numbers.slice(0, 3).join('');
    let secondPart = numbers.slice(3, 6).join('');
    let thirdPart = numbers.slice(6).join('');

    const phoneNumber = `(${firstPart}) ${secondPart}-${thirdPart}`;

    return phoneNumber;
}
console.log(createPhoneNumber([1, 2, 3, 4, 5, 6, 7, 8, 9, 0]));
```
Algorithm to Convert string to camel case "CodeWars"
Tags: javascript, algorithms, node, programming
Published: 2023-09-09 14:26:44

The Problem
Complete the method/function so that it converts dash/underscore delimited words into camel casing. The first word within the output should be capitalized only if the original word was capitalized (known as Upper Camel Case, also often referred to as Pascal case).

should handle empty values
should remove underscores and convert first letter of word to upper case
should remove hyphens and convert first letter of word to upper case

Algorithm.

Step-1 - Create A Variable That will store our camel case words

Step-2 - Create a For loop that will loop through the str. on each iteration I will get the character of the letter using the index of that string.

Step-3 - Using an if statement to check if the a dash(-) or an underscore(_) was found in any of the iterations. if yes them we need to do some manipulations.

Step-4 - If any underscore or dash was found, we need to access the next value after the dash or underscore, this can be done by adding one to the current index. 

Step-5 - Once we get the next character, we are to use the .toUpperCase() to convert to uppercase and then concatenate it with the variable created in step one.

Step-6 - After the concatenation we need to increase index or i by 1 (This is the variable declared in the for loop). This will enable our algorithm not to pick the next character after the underscore or dash because we have taken care of it already.

Step-7 - If no underscore or dash was found in the iteration. we just concatenate the string with the variable declared in step 1.

Step-8 - Finally we return our variable.

```js
function toCamelCase(str){
    let acceptedString = ''
    for(let i = 0; i < str.length; i++){
      let eachChar = str[i]
      if(eachChar == '-' || eachChar == '_') {
        let nextChar = str[i+1]
        acceptedString += nextChar.toUpperCase()
        i++
      }else{
        acceptedString += eachChar
      }
    }
    return acceptedString
}
console.log(toCamelCase("the-stealth-warrior_is-Here"));
```

Check Whether a Number is a Narcissistic Number or Not in Javascript?
Tags: javascript, algorithms, programming, node
Published: 2023-09-09 13:55:32

A number is said to be a narcissistic number, if the addition value of each digit raised to the power of numbers of digits available in the original number is equal to the original number.

For more clarification, if the original number has ‘n’ number of digits, first we have to calculate the nth power of each digit. Then add those value and check if that calculated value and original number both are same then the original number is called as narcissistic number.

Some examples of narcissistic numbers are: 153, 8208, 4210818, ... etc.

In this algorithm below, we will see how to check if a number is a narcissistic number by using Javascript programming language.

Algorithm
Step-1 - Since the input is a number i want to convert to a string first by using the.toString() method

Step-2 - Calculate the number of digits of the original number by using the .length method

Step-3 - Create A variable that will hold the sum of each of the numbers after raising them to the power of the length.

Step-4 - Initiate a loop to extract the digits and calculate the power value of it. Inside that loop add those calculated power values to the variable created above.

Step-5 - Compare both the calculated value with the original number. If the both are same, then the input number is called a narcissistic number then return true else not return false.

```js
function narcissistic(value) {
    value = value.toString()
    let len = value.length
    let digitSum = 0;
    for(let i = 0; i <value.length; i++){
      let eachNumber = parseInt(value[i]);
      digitSum += Math.pow(eachNumber, len);
      console.log(digitSum)
    }
    return digitSum == value
}
console.log(narcissistic(7));
```
