Web Development is an ART that only a Web Developer can Craft.
Hey folks,
Welcome to the wonderful world of Web Development!
These days, it feels like web development is sprinting through a tech marathon. One side is shouting, “AI will build everything for you!” while the others are still figuring out what version of JavaScript we are on.
Here is my take: AI won’t replace web developers — but it’s definitely becoming our new sidekick.
It is taking care of the repetitive work so we can focus on solving bigger challenges and building smarter experiences.
But AI isn’t the only game-changer in town.
Behind the scenes, the entire web stack is evolving — from how our browsers talk to servers (hello, HTTP/3!) to how graphics and code run in your browser (meet WebGPU and WASI). Similar to this, there are lot many
things that have evolved or are evolving
But
Before we zoom into what’s new in 2025, let’s quickly go over what web development actually means — especially if you’re just starting out or need a refresher.
What is Web Development?
At its core, web development is all about building and maintaining websites and web apps — everything from how they look, to how they behave, to how they talk to servers and store your data.
Depending on the roles and technologies involved, web development is generally split into three types:
Frontend Development
This is all the visual stuff — the part users actually see and interact with in their browser. That’s why it is also called as client-side development (because it runs in the client’s browser).
Common Technologies in use:
- Structure & styling: HTML, CSS
- Interactivity: JavaScript / TypeScript
- Frameworks & Libraries: React, Angular, Vue
Backend Development
This is the behind-the-scenes logic — how the website or app works. It’s called server-side development because the code runs on the server and sends results to the frontend.
Common Technologies in use:
- Server logic: Node.js, Python, Java, PHP
- Databases: MongoDB, MySQL, PostgreSQL
Full Stack Development
Think of this as the complete package — frontend + backend + database + deployment. A full stack developer handles the entire flow from user interface to data storage and everything in between.
Now let’s take a look towards the major shifts in the web development technologies:
HTTP / 3
Let’s see what is HTTP in short first,
HTTP stands for the Hypertext Transfer protocol. It is the communication protocol used by web browsers and web servers to send and receive data over the internet.
HTTP/3 is the latest and fastest version of HTTP that is built on a new transfer protocol called QUIC.
Before the advent of HTTP/3, HTTP/1 and HTTP/2 were used which used Transmission Control Protocol(TCP) that had some issues like slow connections especially on mobile, Head-of-line blocking i.e. if one request is delayed all others in line after it must wait, another problem was poor handling of lost packets i.e. if a small piece of data is lost during the transfer of data, TCP makes you wait for it.
In short, HTTP/3 is a next-generation web protocol that solves the issues like speed, reliability and blocking problems of older HTTP versions.
Core Web Vitals
Core Web Vitals are a set of metrics defined by Google to measure the performance of a website by how real users experience a website. These metrics affect your website’s SEO ranking, so they’re important for both developers and business owners.
Originally, three main metrics were used:
LCP (Largest Contentful Paint) — How fast the main content appears
FID (First Input Delay) — How fast the site responds to user input
CLS (Cumulative Layout Shift) — How stable the layout is
The Problem With FID (First Input Delay) was
FID measured only the delay before the browser could start responding to a user’s first interaction (like a tap or click). But it didn’t track whether the website visually responded quickly, the experience felt smooth, the full interaction was fast.
In short, FID was too narrow. It focused just on the start of the interaction, not the full experience.
What’s New: INP (Interaction to Next Paint)
INP = Interaction to Next Paint.
Google introduced INP as a more complete measure of how responsive a site feels.
What INP Measures is not just the first input — it tracks all interactions: taps, clicks, scrolls, drags. Measures the full interaction lifecycle: When you click to how long it takes for the next visible update to appear.
WebGPU
WebGPU is a new web technology that lets your browser (like Chrome, Edge, Safari) talk directly to your computer’s graphics card (GPU).
This means:
Websites can now render high-quality graphics faster (like games, 3D designs, complex animations).
It can also speed up machine learning and other advanced computing tasks inside your browser — no need to install anything!
Before WebGPU, we had WebGL, WebGL2,Canvas/2D.
WebGL use was limited. It couldn’t use modern GPU features available on desktops or mobile devices. It was also not great for non-graphics tasks like AI or data processing.
Canvas/2D were used for simple drawings, charts, or 2D games. It was not suitable for high-end tasks.
What does WebGPU solve?
Old graphics APIs like WebGL that were hard to optimize now uses modern GPU power like DirectX 12, Vulkan, Metal.
WebGL was only for graphics, not for computing tasks but now WebGPU can do both — graphics and computations.
WebGPU is much faster and more efficient in case of complex 3D apps and ML models.
Passwordless SignIn
“Passwordless” means you can sign in to websites or apps without typing a password. Instead, you can use your fingerprint, face, or phone PIN — something you already use to unlock your device.
What are Passkeys?
Passkeys are a new, safer way to log in. They are digital keys stored on your device and protected by biometrics (like Face ID, fingerprint) or your device PIN.
You don’t need to remember anything.
You don’t need to type anything.
You just approve with your face or finger.
Passkeys are like magical keys on your phone that open your accounts — no passwords needed.
You just look at your screen or touch your finger, and you’re logged in.
That was just a wrap on some of the greatest shifts happening in web development! If you liked this, stick around — there’s a lot more coming your way.
