Difference between Module and Package in Node.js
Tags: javascript, node, programming, beginners
Published: 2023-12-11 14:12:35

In Node.js, "module" and "package" refer to different concepts, and they play distinct roles in the Node.js ecosystem.

1. **Module:**
   - A module in Node.js is a reusable piece of code that encapsulates related functionality.
   - It can be a single file or a collection of files organized in a directory.
   - Modules help in organizing code into smaller, manageable pieces, promoting modularity and code reuse.
   - To make functions, variables, or objects from a module available in another module, you use the `exports` object or `module.exports`.
   - Modules are used to structure and break down large applications into smaller, more maintainable parts.

   Example of a simple module (`myModule.js`):
   ```javascript
   // myModule.js
   const greeting = "Hello, ";

   function sayHello(name) {
       console.log(greeting + name);
   }

   module.exports = {
       sayHello: sayHello
   };
   ```

   Using the module in another file (`app.js`):
   ```javascript
   // app.js
   const myModule = require('./myModule');

   myModule.sayHello('Shameel');
   ```

2. **Package:**
   - A package in Node.js is a way of organizing related modules into a directory structure.
   - It contains a `package.json` file, which includes metadata about the package (such as name, version, dependencies, etc.).
   - Packages can be published to the npm (Node Package Manager) registry, allowing others to easily install and use them in their projects.
   - npm is the default package manager for Node.js, and it simplifies the process of installing, managing, and sharing packages.

   Example of a simple package (`my-package`):
   ```
   my-package/
   ├── package.json
   ├── myModule.js
   └── app.js
   ```

   `package.json`:
   ```json
   {
       "name": "my-package",
       "version": "1.0.0",
       "main": "app.js",
       "dependencies": {
           // dependencies go here
       }
   }
   ```

   Using the package:
   ```javascript
   // app.js inside my-package
   const myModule = require('./myModule');

   myModule.sayHello('Shameel');
   ```

   To use this package in another project, you would typically publish it to npm and then install it in your project using `npm install my-package`.

In summary, a module is a single file or a collection of files that encapsulates related functionality, while a package is a way of organizing and distributing related modules, often with additional metadata and dependencies specified in a `package.json` file.
Ideas are the thief of joy
Published: 2023-12-11 14:01:25

You've probably heard the saying, "comparison is the thief of joy." I'm here to add another suspect to the lineup: ideas.

Imagine this - you get a brilliant idea for solving a problem. It's exciting, right? But then, what often happens next is a flood of additional ideas, and before you know it, you're swamped. What started as a clear vision turns into a blur of endless possibilities, and you're stuck in this whirlpool of thoughts with nothing concrete to show for it.

My adventure into coding and full-stack development has been a real eye-opener in this respect. Coming from the fast-paced world of finance, where quick decisions are the norm, diving into tech, especially engineering, has been a whole different ball game. In tech, it turns out, you can't just sprint through projects; it's more of a marathon.

This transition has been quite a shift for me. I've always been a fan of speed, but in engineering, I've learned that rushing through isn't always possible or even beneficial. This realization didn't come easy to me, but it's been a crucial part of my growth.
I'm still on this path, still figuring things out. Every day is a lesson in the importance of properly planning and executing engineering projects. It's about finding that sweet spot between having a wealth of ideas and being able to bring them to fruition effectively.

The big learning for me? Scoping. It's about figuring out what's actually doable within the time and resources available. It's less about the number of ideas you have and more about how practical and impactful they are.

So, as I continue with my project, I'm constantly reminded of the need to strike a balance. It's like walking a tightrope between letting your imagination run wild and keeping your feet firmly on the ground of reality. It's about cherishing the creative process but also staying focused on the end goal.

In the end, what I'm realizing is that this journey in tech is never really over. It's an ongoing process of learning, adapting, and balancing. Ideas are great, but they're just the starting point. The real magic happens in the execution, in bringing those ideas to life in a way that's both imaginative and practical.
Music Monday — What are you listening to? (Synthwave Edition)

**So, you might be thinking _but Michael, we just had the [Synth Heroes Edition](https://dev.to/devteam/music-monday-what-are-you-listening-to-synth-heroes-edition--1fg9) last month... haven't we had enough of this!?_ 😫 To which I say, "Muahahahaha, you can never have enough synthesizer-focused music!!!" Hearing this, you get a bit freaked out and think _how does he know my thoughts..._ to which I respond "Resistance is futile." 😈 Did I take it too far? Always. Are we going to focus on synthwave music this week? You bet your butts we are — we had such a great time on the last thread. So, close the curtains, turn on all your neon lights, and put on the coolest pair of shades you own, we're about to ride the synthwave. 😎**

![It appears as though we're moving forward in a grid of laser lights heading toward a large stylized setting sun. We're in between 2 canyons, but everything is digitized in a simple sort of 80's graphics. It feels very nightrider-esque and the image is very much of the synthwave genre.](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/mobau5cm2nfvy4juig04.gif)

## How we do 

In this weekly series, folks can chime in and drop links to whatever it is they've been listening to recently + browse others' suggestions. You can follow the suggested genre if you'd like, but don't feel confined to it; you're free to suggest whatever you wanna. 🙌  

If you're interested in having other discussions about music, consider following the aptly named [#music discussions](https://dev.to/music-discussions) organization.

{% embed https://dev.to/music-discussions %}

Vaporwave is also welcome in this mix, not that I can really tell the difference between the two! 😆 _Note: you can embed a link to your song using the following syntax `{% embed https://... %}`. This should work for most common platforms!_

Looking forward to listening to y'all's suggestions! 🎶
Understand web Accessibility: semantic HTML (part 8)
Tags: a11y, learning, html, webdev
Published: 2023-12-11 13:59:35

**With over 100 HTML elements, you can create your own markup in infinite ways, but which one will be the best?...**

HTML semantics provide accessibility information about page structure and an element's role, name, and state, helping to convey the nature and purpose of content on web pages. 
By using HTML elements instead of a _div soup_ without any semantic value, you are helping users and Google's robots to understand your web content...
If a developer used a `<div>` instead of a `<header>`, the implicit role would be absent, unless provided with extra code. That means the HTML won't be as useful to the machines that interpret it.

## Structuring content
You can first try to always use semantic landmarks like `header`, `main`, `aside`, `footer` and `nav` elements.
Then, you should also use the good HTML element for each purpose:

- a `p` will be the direct parent of paragraph of text, not a `div`

- if you need a link or an anchor, use an `a` element, not a `button`

- if you need an action (like opening a modal, closing a burger menu, expanding some content, playing a media, validate a form), use a `<button>` element

- for a title or a subtitle, prefer the `h1` to `h6` elements and respect the order

- if you have a list of items, use an `ul` & `li` combo...

## Naming things as they are
Just by this way, using semantic HTML, you can for instance tell to screen reader users that an component is a button, or a link or a list of items. A `div` alone will not provide any information about your content...
Elements like `<div>`s and `<span>`s are meaningless, inert. You can use them for layout and styling, but not to replace semantic HTML5, as it will require a lot of JavaScript to mimic the real HTML5 element. 

**Always choose an existing HTML5 element first!**

History and evolution of JavaScript.
Tags: javascript, beginners, codenewbie, programming
Published: 2023-12-11 12:51:17

**JavaScript** was created to be used on the client/users sides of website's, aiding in the addition of interactive and dynamic components to websites with html and styling from CSS or static html text.
     **JavaScript** gained popularity during the first few years it was developed and introduced as it was used to develop a wide range of applications such as online games, form validation e.t.c.

Over the years **JavaScript** has become one of the most popular programming language worldwide, it is also used in the creation of desktop and mobile applications, programming of robots and creation of server-side app.

       **Brief history of JavaScript**

JavaScript was created in the year "1995" under ten days by "Brendan rich". The programming language was first  called "**"MOCHA"** later on **"livescript"** and now "**JAVASCRIPT"**. It was developed for _Netscape 2, _which was then the most popular browser, later on Netscape handed "JS" over to "ECMA" where it can be called "ECMA-script". Internet Explorer was the first browser to support ES edition 1.

    **Evolution of JavaScript**

After Netscape handed JavaScript to "ECMA", the Mozilla foundation/group continued to develop JavaScript for the Firefox browser which brought about new features and syntax. 

**"Var keyword"** it is used to declare a variable which can later be changed in the code. Es 6(2015) brought about two new keywords "let& const".

- *Let* can be compared to var because it also offers block scope variables.

- *Const* is used to declare a variable which can't be changed.

- *Functions* are objects in JavaScript which can be assigned to a variable, used as arguments and can have value returned from them,
Function syntax=
" Function name(paramus){

}
"

With the use of JavaScript you can add features improve the speed, enhance the performance add functionalities, improve usability to web applications.

You can start using JavaScript by declaring a variable using 
" Let, var, const ".
Make a Vue3 Composable Globally Accessible with Provide/Inject API
Published: 2023-12-11 12:41:21

In a Vue 3 application, you can make a composable globally accessible using the provide/inject pattern. This way, you can inject the composable and its functions into your components without importing it explicitly in each component. 

If you are new to Provide/Inject API in Vue3, I've got you covered! You can read my introduction on this topic here:

[Vue3 Provide/Inject API - Part 1](https://www.codemag.com/Article/2101091/The-Complete-Guide-to-Provide-Inject-API-in-Vue-3-Part-1)
[Vue3 Provide/Inject API - Part 2](https://www.codemag.com/Article/2103071/The-Complete-Guide-to-Vue-3-Plug-ins-Part-2)


Back to our topic on exposing a Composable globally. Let's go through an example:

## Create the Composable

Assuming you have a composable named myComposable that returns a function, here's an example:

```js
// myComposable.js
import { ref } from 'vue';

export function useMyComposable() {
  const myFunction = ref(() => {
    // Your function logic here
  });

  return {
    myFunction,
  };
}
```

## Provide the Composable

In your main application file (like `main.js` or `main.ts`), provide the composable globally using the provide function:

```js
// main.js
import { createApp } from 'vue';
import App from './App.vue';
import { useMyComposable } from './path/to/myComposable';

const app = createApp(App);

const myComposable = useMyComposable();
app.provide('myComposable', myComposable);

app.mount('#app');
```

## Inject the Composable in Components

Now, in any component where you want to use the composable, you can **inject** it using the inject function:


```vue
<script setup>
import { inject } from 'vue';

// Inject the composable
const myComposable = inject('myComposable');

// Now myComposable.myFunction is available for use in this component
</script>

<template>
  <div>
    <!-- Use the function from the composable -->
    <button @click="myComposable.myFunction">Invoke Function</button>
  </div>
</template>
```

By providing the composable at the application level, you can access it in any component without the need to import it explicitly. This follows the global state management pattern using Vue 3's `provide` and `inject`.

:has() pseudo-class
Published: 2023-12-11 12:03:07

As of my last knowledge update in January 2022, the :has() pseudo-class is not part of the CSS standard, and it's not widely supported by browsers. However, there have been discussions and proposals related to this pseudo-class, particularly in the context of Selectors Level 4.

The :has() pseudo-class is intended to allow the selection of an element based on whether it contains a specific selector. Here's a hypothetical example of how it could be used in a real-world scenario once it's supported:

## CSS Code
```
p:has(a) {
  background-color: lightblue;
  padding: 20px;
  border-radius: 7px;
  font-family: 'Arial', sans-serif;
  font-size: 1rem;
  line-height: 1.5rem;
}
p a {
  color: tomato;
}
```

## HTML Code
```
<p>Convert px to rem with <a href="https://plexcalc.com/">Plexcalc.com</a> Fast and Accurate Online Calculator and Converter. Lorem ipsum dolor sit, amet consectetur adipisicing elit. </p>
```

In this example, the :has(a) selector is used to select <p> elements that contain an `<a>` (anchor) element. When this pseudo-class becomes widely supported, it could provide a more concise way to select elements based on their content.

As of now, developers typically use JavaScript or other scripting languages to achieve similar effects, dynamically selecting and styling elements based on their content or the presence of specific child elements. The lack of widespread support for :has() in CSS has led to the reliance on JavaScript for such tasks in real-world scenarios.

Keep in mind that browser support for new CSS features can change over time, so it's a good practice to check the latest specifications and browser compatibility tables to see if there have been updates since my last knowledge update in January 2022.
