Ready to unlock the secrets of the web? Let's decode the essential jargon! 💻

1. **Packets**: These are like digital envelopes. Your data is broken down into packets for a safe journey across the internet.

2. **Router**: The traffic conductor, guiding packets to their destination. Think of it as your digital GPS.

3. **IP Address**: Unique digital ID for devices. Just like your home address, it ensures data reaches the right doorstep.

4. **Domain Name**: Web addresses we can actually remember, like "facebook.com" or "amazon.com."

5. **DNS (Domain Name System)**: The phone book of the internet. It translates human-friendly domain names into machine-friendly IP addresses.

6. **HTTP & HTTPS**: The chat language between your browser and websites. HTTP is the norm, but HTTPS adds a layer of security with data encryption.

7. **SSL/TLS**: The digital bodyguards. They shield your data during transit, making sure it's for your eyes only.

8. **HTTP Methods**: These are the actions you take on the web. Common methods include:
   - **GET**: Retrieve data from a server.
   - **POST**: Send data to be processed by the server.
   - **PUT**: Update data on the server.
   - **DELETE**: Remove data from the server.
   - **PATCH**: Make partial updates to data on the server.

9. **HTTP Status Codes**: The web's way of talking back to your browser. Some key ones include:
   - **200 OK**: Everything went well.
   - **404 Not Found**: The requested page doesn't exist.
   - **500 Internal Server Error**: Something went wrong on the server's end.

These are the basics, the starting point for your web dev journey. There's a lot more to explore, but mastering these fundamentals is your first step! 🌐🚀

Growing My Skill in Web Accessibility
Tags: webdev, webaccessibility, accessiblecode, a11y
Published: 2023-10-27 12:21:44

As a self-taught web developer, my first impulse whenever I encounter a new concept is to search the Web. There's almost always a blog post or video that explains it in enough detail to help me understand. For the most part, this has been no different for web accessibility.

## Using Online Resources
Once I learnt about [web accessibility on Mozilla](https://developer.mozilla.org/en-US/docs/Learn/Accessibility), it was quite easy to find other related posts. I found several excellent posts to expand my knowledge of accessible web development. I learnt to write accessible code with semantic Hypertext Markup Language (HTML) elements. I also learnt to test my websites with automated testing tools such as WAVE, axe DevTools and ARC Toolkit. To understand how blind users experience my websites, I learnt to test with NVDA and TalkBack screen readers. I also learnt to enhance the output of screen readers with Accessible Rich Internet Applications (ARIA) when there are no HTML alternatives.

## Learning from a Great Mentor
As my knowledge of web accessibility grew, I realized that I was lacking an important skill. I didn't know how to perform a manual accessibility audit. I searched the Web but I couldn't find a simple guide on the process of manual accessibility testing. Yet, I knew I had to gain this skill. Manual auditing is the only way to identify all accessibility issues on a website.

So, when Rachele DiTullio posted on LinkedIn that they had created [manual accessibility audit videos](https://racheleditullio.com/projects/accessibility-testing/), I was excited. First, I watched the videos to understand their testing process. Then, I sent them an email requesting their mentorship. They were very receptive and agreed to mentor me. They agreed to provide weekly testing exercises and give feedback on the results. Thus began my journey into manual web accessibility auditing.

  <figcaption>**My first manual accessibility testing workbook**</figcaption>
</figure>

## The Journey So Far
As I've performed manual accessibility audits, my skill have evolved over time. I've learnt to break down each webpage into smaller sections to test. I'm learning to better interpret the Web Content Accessibility Guidelines (WCAG). I'm learning how WCAG failures impact the web experience of users with disabilities. It's a journey. I'm getting better at it.
Riding the Wave: Today's Top Web Design Strategies in Business Tech
Tags: webdev, web, design
Published: 2023-10-27 12:20:19

Hello there,

Hope you’re all doing fantastic! Today, I wanted to chat about something that’s been buzzing in the tech world and, more importantly, how it’s making waves right here in our own backyard. Web design in business software—it’s a big deal, and it’s time we had a good ol’ heart-to-heart about the trends shaping our craft.

**Simplicity Speaks Volumes**

Alright, let's dive right in. Minimalism—it’s not just for artists and interior decorators. In the world of web design, less really is more. We’re talking clean lines, clear interfaces, and content that gets straight to the point. The goal? Make life easier for our users. Because, let’s face it, nobody’s got time to navigate through a maze.

**A Splash of Color**

Now, just because we’re keeping things simple, doesn’t mean we can’t have a bit of fun. Business software’s shedding its old, stodgy skin and embracing a bolder, more vibrant look. But here’s the catch—it’s all about striking the right balance. How do we inject a bit of personality into our designs without crossing over into the realm of “too much”? It’s a fine line, and it’s where the magic happens.

**Make it Move**

Static is out, dynamic is in. We want our users to do more than just look; we want them to interact. Think micro-interactions, think animation. But remember, the aim is to enhance, not overwhelm. Every element should have a purpose, adding to the user’s experience, not detracting from it.

**Thinking Mobile, Thinking Smart**

This one’s a no-brainer. Mobile-first isn’t just a buzzword—it’s a necessity. Our designs have to shine on every device, big or small. And it’s not just about making things fit on a smaller screen. It’s about understanding how users interact with their devices and tailoring our designs to suit their needs.

**User Experience is King**

And finally, we circle back to the heart of it all—user experience. Everything we do, every trend we follow, it’s all in the service of creating a smoother, more intuitive experience for our users. Because a happy user is a loyal user, and in the world of business software, loyalty is worth its weight in gold.

So, there you have it—the trends shaping our world and keeping us on our toes. But this isn’t a one-way conversation. I want to hear from you. What trends have you excited? What challenges are you facing? Let’s start a dialogue and navigate these waters together.
How to Handle CSP Header Challenges with Dynamic URLs in Next.js Multi-Tenant Applications?
Tags: security, frontend, nextjs, webdev
Published: 2023-10-27 12:16:14

Hello,
I'm encountering an issue with my Next.js application, which is a multi-tenant setup. The problem lies in setting up the Content Security Policy (CSP) headers, as the URLs are dynamic and depend on the tenant name extracted from the frontend URL. The CSP is blocking the URL.

The error I am encountering is:
`xhr.js:220 Refused to connect to 'https://xyz/qa/api/users/auth/login/' because it violates the following Content Security Policy directive: "connect-src 'self' https://xyz/tenants//api".`

Here's the function I'm using to extract the tenant name
export const **getTenantfromURL** = () => {
  try {
    const { origin } = absoluteUrl();
    if (origin === "http://localhost:3000") {
      return "qa";
    } else {
      const tenantName = new URL(origin).hostname.split(".")[0];
      return tenantName;
    }
  } catch (e) {}
  return "";
};

The BASE_URL variable is defined as:
export const BASE_URL = `https://xyz.tenants/${**getTenantfromURL**()}/api`;

And in my _document.js, I've defined the CSP as follows:
**const csp** = `default-src 'self' 'nonce-${nonce}#m' 'unsafe-inline'; worker-src blob:; script-src 'self' 'nonce-${nonce}' 'unsafe-inline' 'unsafe-eval' https://vercel.live/ ${BASE_URL}/alerts/data/; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; img-src 'self' ; font-src 'self' https://fonts.googleapis.com https://fonts.gstatic.com; connect-src 'self' ${BASE_URL}; frame-src 'self'; object-src 'none'; media-src 'self' ${BASE_URL}/alerts/data/; form-action 'self'; manifest-src 'self' ${BASE_URL}/demo; prefetch-src 'self' ${**BASE_URL**}/demo; frame-ancestors 'self'`;


 The URL appears as `**https://xyz/tenants//api**`, indicating an issue with constructing the URL from the extracted tenant name.

I'm seeking advice on whether there's an alternative method for incorporating dynamic URLs into CSP headers and resolving the issue with the malformed URL.

Please let me know if you have any suggestions or if there's a better way to handle dynamic URLs within CSP headers.

Updating Service Workers in Production
Tags: javascript, sw, tutorial
Published: 2023-10-27 11:48:47

Service Workers are powerful tools within web browsers that enable a plethora of offline operations, including caching, real-time notifications, geolocation handling, and more exciting features. However, due to their separation from web applications and their role as proxy servers between connections, dealing with them in production can be quite challenging, especially when it comes to managing browser caches.

## How to Update a Service Worker in Production?  
There are several reasons why you might need to update a service worker in production. Consider a scenario where you want to change the path of your service worker. You previously had a service worker that only worked within the login path of your application, but now you want it to function globally.

In such cases, it's crucial to ensure that two services aren't running concurrently on the same routes, to avoid operational duplication. To address this, you can execute the following code in the entry point of your application:

```tsx
if ('serviceWorker' in navigator) {
    const registrations = await navigator.serviceWorker.getRegistrations();

    const oldSw = registrations.find((registration) =>
      registration.active?.scriptURL.includes('/login/sw.js'),
    );

    if (oldSw) {
      oldSw.unregister();
    }

    navigator.serviceWorker.register('/sw.js');
}
```

With this code, you can identify a service worker running on a specific path, unregister it, and then re-register it with the desired path. This ensures that the service worker previously registered under `/login` is no longer active and allows the one registered under `/` to handle all the tasks.

## Ensuring All Users Have the Updated Version

You can also ensure that browsers update all service workers without waiting for the entire application to restart:

```tsx
self.addEventListener('install', (event) => {
  event.waitUntil(self.skipWaiting());
});
```

However, this action is not always recommended. It's best to wait for the complete [service worker lifecycle](https://web.dev/service-worker-lifecycle/) to occur correctly. Use this approach only if your change won't result in a breaking change for the client, and avoid using it for significant changes.

Updating service workers in production requires careful planning and consideration of how changes might impact user experience. By following these best practices, you can efficiently manage service worker updates and enhance the performance and reliability of your web applications.

Dynamic HTTP API for web & OS dev 🧢
Tags: rust, webdev, tutorial, api
Published: 2023-10-27 11:42:28

Today we'll be writing a working web API using an extremely simple HTTP library controlable from the console of your computer. Let gonna se the implementation

First, crate a new folder and add [k_board](https://crates.io/crates/k_board) & [snowboard](https://crates.io/crates/snowboard).

`cargo new http-api && cd http-api && cargo add k_board && cargo add snowboard`

```rust
use k_board::{Keyboard, Keys};
use snowboard::{response, Server};

fn main() {
    for key in Keyboard::new() {
        match key {
            Keys::Enter => router("localhost:3000"),
            Keys::Letter('q') => break,
            _ => {}
        }
    }
}

fn router(localhost: &str) {
    println!("Running in localhost:3000 - `curl localhost:3000`");
    Server::new(localhost).run(|req| {
        println!("Request: {:?}", req);
        response!(ok, "You are in localhost 3000!\n")
    });
}
```

If you press enter you active the server listening all call, then when you make a `curl localhost:300` you will receive the answer of the server.

```bash
mateo@debian:~/http-api$ curl localhost:3000
You are in localhost 3000!
```

---

That a simple example in which it just take the enter key as an activator of the server, if your looking for an specific handling of the keys for server activation , you can look at Keys struct of k_board.

```rust
pub enum Keys {
    Up,
    Down,
    Left,
    Right,
    Enter,
    Space,
    Delete,
    Escape,
    Plus,
    Minus,
    Equal,
    Power,                 ^
    Slash,                 /
    Backslash,             \
    Asterisk,              *
    Point,
    Comma,
    Hashtag,
    Pipe,                  |
    Percent,               %
    Ampersand,
    Currency,              $
    TwoPoints,             :
    Semicolon,             ;
    OpenSquareBracket,     [
    CloseSquareBracket,    ]
    OpenCurlyBrace,        {
    CloseCurlyBrace,       }
    OpenQuestionMark,      ¿
    CloseQuestionMark,     ?
    OpenParenthesis,       (
    CloseParenthesis,      )
    LessThan,              <
    GreaterThan,           >
    Apostrophe,            ' 
    At,                    @
    Home,
    End,
    Tab,
    Backtab,
    Insert,
    Letter(char),
    Number(u8),
    F(u8),
    Ctrl(char),
    Alt(char),
    Null,

Debugging Node.js like a PRO
Tags: node, vscode, debug, javascript
Published: 2023-10-27 11:34:31

If you opened this post, you want to unlock the ultimate power of debugging node.js apps. I think you will agree that the `console.log` is still the king. It's time you close the article now. Or not...

The other day, I was trying to debug why a migration takes forever to run. Unfortunately, it was using a 3rd party package to do that, so I did not have direct access to the codebase(except by going to the `node_modules` folder or GitHub). But even if I can open the code, of course, it's tough to understand it. 

### If there could be a way to hook into the code execution...
Wait, there actually is. Just follow the official guide for [Debugging in node](https://nodejs.org/en/docs/guides/debugging-getting-started), and you're done. However, for some reason(I bet it has something to do with the `worker_threads` or some child process) it didn't worked in my case. 

Another option would be to use the [.vscode/launch.json](https://code.visualstudio.com/docs/editor/debugging#_launchjson-attributes) file, but I always find it painful to create and read.

### Can there be an even easier way to run debug mode for node?
The answer is simple: YES. And this was the day when I found the `Debug: Toggle Auto Attach` command in VS Code(my current editor of choice, as I can't finish my Neovim config 😀). Just press `Cmd(or Ctrl)+Shift+P`, paste `Debug: Toggle Auto Attach` and choose from one of the available modes: `Always`, `Smart`, `Only With Flag`, `Disabled`. You can read more about each option [here](https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_auto-attach). 

After selecting the option, all you have to do now is to restart your terminal in VS Code, add the breakpoint in your code, run the node script(via `node`, `npm`, `yarn`, etc) and focus on identifying and solving the problem.

For my case, I used the `Always` option, as I wanted to have the debugger running for all the node processes that run in my terminal. This way, I was able to find and report the problem of why the migration ran slow(fetched too many rows because of a specific config option, which should not be the case). Once I was done, I chose `Disabled` option and got back to the king of debugging, `console.log`.

I hope you enjoyed the post and it was somewhat helpful.
