πΈ Building an Offline-Friendly Image Upload System
Poor internet connectivity doesn't have to mean poor user experience. With PWA technologies like IndexedDB, service workers, and the Background Sync API, you can create an offline-friendly image upload system that queues uploads when users are offline and automatically syncs them when the connection is restored.
This approach means your app keeps working even when the network goes down - users can continue uploading images without interruption, and everything gets handled automatically in the background when connectivity returns.
Read the full guide on creating this resilient image upload system: https://www.smashingmagazine.com/2025/04/building-offline-friendly-image-upload-system/
π Mastering TypeScript Configuration
The tsconfig.json file is your TypeScript project's control center. It tells the TypeScript compiler exactly how to process your code, from which files to include to what JavaScript features to target.
This comprehensive guide walks you through all the essential configuration options - both standard and experimental. You'll learn what each setting does and how it impacts your final compiled output.
Whether you're setting up a new project or optimizing an existing one, understanding tsconfig.json is key to unlocking TypeScript's full potential.

πͺ The New Cookie Store API
Modern web applications finally get a clean, async way to handle browser cookies. This new API replaces the clunky old
document.cookie string parsing with three major improvements:
First, it's asynchronous β no more performance jank from synchronous cookie operations. You can read and write cookies without blocking the main thread.
Second, it includes change events. Instead of polling for cookie changes, you can simply listen to change events to track modifications across tabs or by service workers.
Third, it brings standardization. The API works consistently across pages and service workers, making it easier to build shared SDKs and libraries.
Check out the details here: https://fotis.xyz/posts/the-new-cookie-store-api/π©Claude vs Cursor: Which one is better for vibe-coding?
If you want to code fast, prototype ideas, and keep the flow, hereβs the simple breakdown.
βοΈ Claude Code
β’ Great at understanding large projects and complex logic.
β’ Helps with architecture, clean code, refactoring, and deep reviews.
β’ Better for long-term, serious projects.
β’ But it works through the terminal, so the workflow is less βinstantβ.
βοΈ Cursor
β’ Full IDE experience with quick edits, autocompletion, and fast responses.
β’ Perfect for prototyping, experiments, small features, and rapid development.
β’ Super convenient when you want speed and smooth workflow.
β’ But in very large projects it can lose context and be less reliable.
What to choose?
β’ For smart, clean, scalable code β choose Claude Code.
β’ For fast vibes, experiments, and quick builds β choose Cursor.
Most developers use both: Cursor for speed, Claude for depth.
ββοΈWhy FAQs matter: how they shape SEO/GEO and AEO
A well-written FAQ section helps users stay on your pages longer and improves search engine optimization by converting hidden questions into concise, easily readable answers. Weβll go over the importance of FAQ content, how schema affects what Google displays, and why FAQs are effective for SEO/GEO in this guide.
β¬οΈ Container Queries β a new way to make layouts responsive.
Before: @media rules reacted to screen width (e.g. under 768px β smaller font).
Problem: components behave differently in cards, sidebars, modals β viewport alone isnβt enough.
Container Queries let CSS adapt to a parentβs size, not the whole screen.
βΉοΈ Example:
.card { container-type: inline-size; }
@container (max-width: 400px) {
.card-title { font-size: 1rem; }
}
How it works
β’ Mark a container with container-type.
β’ Use @container to style elements inside it.
β’ Components adapt to parent width, no global media hacks.
β’ Cleaner CSS, fewer JS tweaks, local responsive behavior.
π Supported natively in modern browsers β truly component-based CSS.

π― Improve LCP and CLS: 7 Tactical Fixes You Can Do This Week (tutorial + code snippets)
Core Web Vitals can feel like a moving target, but a few targeted changes often move the needle quickly. This article walks through seven tactical fixes you can apply in days, not months, with code samples and real-world tips so you can improve LCP and fix CLS without a complete site rewrite.
Iβll show how to identify the biggest offenders, apply precise HTML/CSS/JS changes, and verify results with lightweight instrumentation. If you implement these steps methodically, you should see measurable improvements in LCP and CLS within a single sprint.
Hey everyone!
Have you noticed how crazy the job marketβs getting with all this AI stuff? π€
Iβve really felt the shift myself. It used to be simple β show up, code all day, get your paycheck at the end of the month. Easy life π
Now? Youβve gotta do everything.
Code fast, understand business processes, talk to clients, know SEO, Google Ads, Analytics, Tag Manager, user behavior β the whole package.
Feels like companies want one person who can do it all π
So I decided to level up my blog and share more than just dev stuff.
New topics are coming:
β’ SEO (Technical, Content, Local, E-E-A-T, SERP / AEO)
β’ Content & Paid Media, Email, Social (incl. short video), Analytics
β’ Web Business Strategy
Itβs gonna be useful for devs, business owners, and anyone building their own marketing agency.

π CSS Relative Colors
Over the years, we have been used to using CSS pre-processors like Sass for a use case like applying opacity to a pre-defined color. Today, we have a new way to do that and more with CSS relative colors. In this article, I aim to shed the light on that and introduce how it works along with many practical examples.
π€ Extension
cpdown - A Chrome extension that copies the content of any webpage and formats it into Markdown. It can, for example, extract and convert YouTube subtitles into a clean Markdown file with a single click.
π΅ How Cursor (AI IDE) Works
Understanding how AI coding tools like Cursor, Windsurf, and Copilot function under the hood can greatly enhance your productivity, enabling these tools to work more consistently β especially in larger, complex codebases. Often when people struggle to get AI IDEs to perform effectively, they treat them like traditional tools, overlooking the importance of knowing their inherent limitations and how best to overcome them. Once you grasp their internal workings and constraints, it becomes a 'cheat code' to dramatically improve your workflow. As of writing this, Cursor writes around 70% of my code
