AI vs Generative AI vs AI Agents vs Agentic AI

Darshan Raval — Sat, 25 Jul 2026 20:24:13 +0000

If you've been following AI over the past year, you've probably seen these terms everywhere:

Artificial Intelligence (AI)
Generative AI
AI Agents
Agentic AI

Many people use them interchangeably.

But they're not the same thing.

Understanding the difference can completely change how you think about building AI-powered applications.

Let's break it down.

🤖 Artificial Intelligence (AI)

Artificial Intelligence is the broad field of creating machines that can perform tasks that normally require human intelligence.

Examples include:

Face recognition
Spam detection
Fraud detection
Recommendation systems
Chess-playing computers

Notice something?

None of these generate text or images.

They simply make intelligent decisions based on data.

Think of AI as the umbrella that covers every intelligent system.

✨ Generative AI

Generative AI is a subset of AI.

Instead of just making decisions, it creates new content.

It can generate:

Text
Images
Code
Videos
Music

Examples include:

ChatGPT
Claude
Gemini
Midjourney
GitHub Copilot

Ask it to write an email.

It writes one.

Ask it to generate React code.

It generates it.

Generative AI is incredibly creative...

But it only responds to your request.

It doesn't take action on its own.

🤖 AI Agents

This is where things become interesting.

An AI Agent doesn't just answer questions.

It performs tasks.

Imagine asking:

"Analyze my GitHub repository, find performance issues, create a report, and open a pull request."

A chatbot would stop after generating advice.

An AI Agent can:

Read your repository
Analyze the code
Use external tools
Generate fixes
Create a pull request
Notify you when it's done

That's a completely different level of automation.

An AI Agent combines:

An LLM
Memory
Tool usage
Planning
Decision-making

It behaves more like a teammate than a chatbot.

🚀 Agentic AI

Agentic AI takes the concept even further.

Instead of completing a single task...

It works toward a goal.

For example:

"Reduce customer support tickets by 30%."

An Agentic AI system may:

Analyze support data
Identify common issues
Update documentation
Improve chatbot responses
Measure results
Repeat the process automatically

It continuously plans, acts, learns, and adapts.

In other words...

AI Agents complete tasks.

Agentic AI pursues objectives.

📊 Quick Comparison

Technology	Main Purpose	Example
AI	Make intelligent decisions	Fraud detection
Generative AI	Create content	ChatGPT writing code
AI Agents	Perform multi-step tasks	AI reviewing your codebase
Agentic AI	Autonomously achieve goals	AI improving an entire support system

💡 Why Developers Should Care

The future isn't just about asking AI better questions.

It's about building systems where AI can:

Use tools
Access memory
Plan workflows
Make decisions
Collaborate with humans

That's exactly why AI Agents and Agentic AI are becoming the next big shift in software engineering.

Final Thoughts

Think of it like this:

AI is the entire field.
Generative AI creates content.
AI Agents perform tasks.
Agentic AI pursues goals.

The technology is evolving quickly.

Understanding these differences today will help you build better AI applications tomorrow.

Which stage are you currently working with—Generative AI, AI Agents, or Agentic AI? I'd love to hear your experience in the comments.

I Built an AI Employee Instead of an AI Chatbot

Darshan Raval — Wed, 22 Jul 2026 20:25:23 +0000

I Built an AI Employee Instead of an AI Chatbot

Everyone seems to be building AI chatbots.

I decided to build something different.

An AI employee.

And it completely changed how I think about AI applications.

We've Been Building the Wrong Thing

For the last couple of years, the default AI project looked something like this:

Add a chat window.
Connect it to an LLM.
Ask questions.
Get answers.

It works.

But after the initial excitement, I noticed something.

People rarely wanted another chatbot.

They wanted someone—or something—that could actually do the work.

That's when I stopped asking:

"How can I build a better chatbot?"

And started asking:

"How can I build an AI teammate?"

A Chatbot Gives Answers

Imagine asking a chatbot:

"Can you create today's sales report?"

It might generate SQL.

Explain the steps.

Or tell you how to build the report.

Useful?

Absolutely.

But you still have to do the work yourself.

The chatbot is acting like a search engine with better communication skills.

An AI Employee Gets Work Done

Now imagine an AI employee.

You give it the exact same request:

"Create today's sales report."

Instead of explaining how to do it, the AI:

Connects to your database.
Retrieves today's sales.
Generates charts.
Creates a PDF report.
Uploads it to Google Drive.
Sends the report to your Slack channel.
Notifies your manager.

No copy-paste.

No manual steps.

Just results.

That's the difference.

The Architecture Shift

A chatbot has a simple architecture.

User
 │
 ▼
Prompt
 │
 ▼
LLM
 │
 ▼
Response

An AI employee is much more capable.

User
 │
 ▼
Planner
 │
 ▼
Memory
 │
 ▼
Knowledge (RAG)
 │
 ▼
Tool Calling
 │
 ▼
Business Rules
 │
 ▼
Multiple APIs
 │
 ▼
LLM
 │
 ▼
Completed Task

The language model becomes just one part of a much larger system.

What Makes an AI Employee?

An AI employee usually combines several capabilities.

Planning

Instead of responding immediately, it breaks a goal into smaller tasks.

Example:

Prepare weekly engineering report

↓

Collect GitHub commits

↓

Analyze Jira tickets

↓

Generate summary

↓

Email stakeholders

The AI is thinking in workflows rather than responses.

Memory

A real employee remembers things.

So should your AI.

For example:

Team preferences
Previous conversations
Frequently used documents
Project context
Customer history

Without memory, every conversation starts from zero.

Tool Calling

This is where AI becomes genuinely useful.

Instead of hallucinating information, it interacts with real systems.

Examples include:

GitHub
Jira
Slack
Gmail
PostgreSQL
MongoDB
Google Drive
Notion
Calendar APIs
Internal company services

The AI doesn't just talk.

It acts.

Knowledge Retrieval

Employees don't memorize every document.

They look things up.

Modern AI should do the same.

Using Retrieval-Augmented Generation (RAG), an AI employee can search:

Product documentation
Internal wikis
Company policies
Technical documentation
API references
Support articles

Instead of guessing, it retrieves the right information before responding.

A Real Example

Imagine you're building an AI employee for your engineering team.

Every morning it automatically:

Reads overnight production logs.
Checks failed deployments.
Reviews open GitHub issues.
Summarizes customer feedback.
Detects unusual error spikes.
Creates a daily engineering report.
Sends it to Slack before stand-up.

Nobody had to ask.

Nobody clicked a button.

The work simply happened.

That's much closer to having a teammate than a chatbot.

Why This Matters for Developers

Building AI employees requires a different mindset.

Instead of asking:

"What should the model say?"

You start asking:

What tools does it need?
What information should it remember?
Which APIs should it call?
How should it recover from failures?
Which tasks can it automate?
What permissions should it have?

You're designing systems, not conversations.

AI Employees Need More Than an LLM

The most capable AI applications today aren't powered by a single model.

They're powered by a complete ecosystem.

That ecosystem often includes:

LLMs
Model Context Protocol (MCP)
RAG pipelines
Long-term memory
Vector databases
Workflow orchestration
Tool calling
Observability
Security and permission layers

The language model is important.

But it's only one component.

Challenges You'll Face

Building an AI employee isn't just about connecting APIs.

You'll also need to think about:

Authentication and authorization
Rate limiting
Error handling
Human approval for critical actions
Logging and observability
Cost optimization
Data privacy
Prompt injection attacks

The more responsibility you give AI, the more engineering discipline it requires.

The Future Isn't More Chatbots

Every company already has enough dashboards.

Enough forms.

Enough chat windows.

What businesses actually need are systems that reduce repetitive work.

That's why I believe the next generation of AI products won't be remembered as chatbots.

They'll be remembered as digital teammates that quietly complete tasks in the background.

Final Thoughts

Chatbots changed how we interact with software.

AI employees will change how work gets done.

The shift isn't about making conversations smarter.

It's about building systems that can plan, remember, retrieve information, use tools, and complete real tasks with minimal human intervention.

As developers, that's an exciting challenge.

Because we're no longer just building interfaces for AI.

We're building coworkers.

Stop Writing Prompts. Start Writing Context

Darshan Raval — Wed, 22 Jul 2026 20:18:10 +0000

Stop Writing Prompts. Start Writing Context.

For months, everyone talked about writing better prompts.

In 2026, the developers building the best AI products aren't obsessed with prompts anymore.

They're obsessed with context.

The Shift Nobody Saw Coming

A year ago, my prompts looked something like this:

Build a REST API using Node.js.

The result?

Sometimes good.

Sometimes terrible.

Sometimes completely unrelated.

So I kept improving the prompt.

More details.

More examples.

More instructions.

But eventually I realized something:

The prompt wasn't the problem. The AI simply didn't know enough.

That changed everything.

Prompt Engineering Is Reaching Its Limits

A prompt is only one small part of an AI request.

Think about hiring a new developer.

Would you simply say:

"Build me an authentication system."

Of course not.

You'd share:

Existing codebase
Tech stack
Coding standards
API documentation
Database schema
Business rules
Previous implementation
Team conventions

The more context they have...

the better the result.

AI works exactly the same way.

What Is Context Engineering?

Context Engineering is the practice of giving AI everything it needs to make good decisions—not just good instructions.

Instead of writing:

Create a login API.

You provide:

Project:
Node.js + NestJS

Database:
PostgreSQL

Authentication:
JWT + Refresh Token

Coding Style:
Repository Pattern

Validation:
class-validator

Existing APIs:
User Registration
Password Reset

Security Requirements:
Rate limiting
bcrypt
RBAC

Expected Output:
Production-ready code

Notice something?

The prompt barely changed.

The context did.

Context Is More Than Just Text

Many developers think context means "write a longer prompt."

It doesn't.

Context includes everything the model can use to make better decisions.

Examples include:

Source code
Documentation
Database schema
API specifications
Previous conversations
User preferences
Company guidelines
Error logs
Design files
Images
Test cases
Memory
Retrieved knowledge (RAG)
Tool outputs

This is why modern AI applications feel dramatically smarter.

They're not using bigger prompts.

They're supplying richer context.

A Simple Comparison

Prompt Engineering	Context Engineering
Focuses on wording	Focuses on information
One prompt	Complete environment
Static	Dynamic
Manual	Automatically assembled
Good for ChatGPT	Essential for production AI
Limited knowledge	Rich business knowledge

How Modern AI Apps Actually Work

A production AI application rarely sends only your prompt.

Instead, it builds context behind the scenes.

User Request
      │
      ▼
Understand Intent
      │
      ▼
Retrieve Relevant Knowledge (RAG)
      │
      ▼
Load Conversation Memory
      │
      ▼
Collect Project Files
      │
      ▼
Call Required Tools
      │
      ▼
Inject Business Rules
      │
      ▼
Send Complete Context to LLM
      │
      ▼
Generate Response

This hidden pipeline is what separates toy demos from production-ready AI systems.

A Real Example

Suppose your manager asks:

"Generate a new Orders API."

A prompt-only approach might produce something generic.

A context-aware system already knows:

The project uses NestJS
PostgreSQL is the primary database
Swagger documentation is required
Every API follows repository pattern
JWT authentication is mandatory
Response format is standardized
Validation uses class-validator
Logging is handled by Winston
Unit tests are written with Jest

Without changing the prompt...

the output becomes dramatically better.

Why Developers Should Care

As developers, we naturally think in terms of systems.

AI should be treated the same way.

Instead of asking:

"How can I write a better prompt?"

Ask:

"How can I provide better context?"

That one mindset shift changes how you build AI products.

The Rise of Context-Aware Development

Today's AI stack is no longer just:

User → Prompt → LLM

It's becoming:

User
 │
 ▼
Memory
 │
 ▼
RAG
 │
 ▼
Tool Calling
 │
 ▼
Project Knowledge
 │
 ▼
Business Rules
 │
 ▼
LLM
 │
 ▼
Response

This is why concepts like:

Model Context Protocol (MCP)
Retrieval-Augmented Generation (RAG)
Tool Calling
Long-Term Memory
Agent Workflows

have become essential skills for modern developers.

They all exist for one purpose:

Deliver the right context to the model at the right time.

Practical Tips

If you're building AI applications today, start thinking beyond prompts.

Instead:

Give the model your project structure.
Include relevant documentation.
Retrieve only the knowledge it needs.
Maintain conversation memory.
Let AI use tools instead of guessing.
Define coding conventions.
Provide examples from your own codebase.
Keep context fresh and relevant.

The quality improvement is often far greater than switching to a more expensive model.

Final Thoughts

Prompt Engineering helped us discover what AI could do.

Context Engineering is teaching us how to build AI that people can actually trust.

The future isn't about writing clever prompts.

It's about designing systems that deliver the right information at the right moment.

Because in the end...

AI doesn't make decisions based on your prompt.

It makes decisions based on the context you give it.

MCP Explained for Beginners: The Easiest Way to Understand Model Context Protocol

Darshan Raval — Mon, 20 Jul 2026 19:04:43 +0000

MCP Explained for Beginners: The Easiest Way to Understand Model Context Protocol

"Think of MCP as USB-C for AI."

That's the simplest explanation I've found.

When I first heard about Model Context Protocol (MCP), I assumed it was just another AI buzzword.

It wasn't.

After spending time understanding it, I realized MCP solves one of the biggest problems in today's AI ecosystem.

Let's break it down in plain English.

The Problem

Imagine every AI assistant needed a custom integration for every tool.

For example:

ChatGPT → GitHub
ChatGPT → Slack
ChatGPT → Notion
Claude → GitHub
Claude → Jira
Gemini → Database

Now imagine adding hundreds of different tools.

Every AI provider has to build every integration.

Every tool has to support every AI.

That doesn't scale.

Enter MCP

Model Context Protocol (MCP) is an open standard that lets AI models communicate with external tools using a common language.

Instead of building dozens of custom integrations...

Everyone speaks the same protocol.

Think about it like this.

Before USB-C:

📱 Different devices needed different cables.

After USB-C:

One cable works almost everywhere.

MCP does something similar for AI.

How MCP Works

A typical MCP setup looks like this:

You
 │
 ▼
AI Assistant
 │
 ▼
MCP Client
 │
 ▼
MCP Server
 │
 ├── GitHub
 ├── Database
 ├── Files
 ├── Slack
 ├── Notion
 └── Custom APIs

The AI doesn't directly know how to use GitHub or your database.

Instead...

It asks the MCP Server.

The server performs the task and sends the result back.

A Real Example

Imagine saying:

"Show me all open GitHub issues assigned to me and summarize them."

Without MCP:

❌ AI can't access GitHub.

With MCP:

✅ AI connects to the GitHub MCP Server.

✅ Fetches your issues.

✅ Reads them.

✅ Creates a summary.

All in one conversation.

Why Developers Should Care

MCP is making AI assistants much more useful.

Instead of only generating text...

They can actually interact with your tools.

Imagine asking AI to:

Review pull requests
Read log files
Query databases
Create Jira tickets
Update Notion pages
Search internal documentation
Trigger CI/CD pipelines

That's a huge shift.

Why Everyone Is Talking About MCP

Many AI companies and developer tools are adopting MCP because it provides:

A common integration standard
Better interoperability
Easier tool development
Reusable connectors
Less duplicated work

Instead of creating a new integration for every AI model, developers can build an MCP server once and make it available to multiple compatible AI clients.

What MCP Is NOT

A common misconception is that MCP is:

❌ A new AI model

❌ A replacement for LLMs

❌ Another chatbot

It's none of those.

MCP is simply the bridge between AI models and external tools.

Should You Learn MCP?

If you're building:

AI applications
Developer tools
AI agents
Internal company assistants
Automation platforms

then yes.

Understanding MCP today is similar to learning REST APIs a decade ago.

It may not seem essential yet.

But it's quickly becoming part of the AI ecosystem.

Final Thoughts

MCP doesn't make AI smarter.

It makes AI more capable.

The real power of AI isn't just generating answers.

It's securely connecting to the tools developers use every day.

And that's exactly what MCP is designed to do.

Have you started experimenting with MCP yet?

If yes, what are you building?

I'd love to hear your thoughts in the comments. 🚀

The AI Wave of 2026: 10 New Things Every Developer Should Know

Darshan Raval — Sun, 19 Jul 2026 19:23:56 +0000

🚀 The AI Wave of 2026: 10 New Things Every Developer Should Know

AI is evolving faster than ever.

If you blink for a month, you'll probably miss a breakthrough.

2026 isn't just about "using ChatGPT."

It's about AI agents collaborating with each other, coding entire applications, browsing the web, generating videos, remembering conversations, and even running businesses.

As developers, staying updated isn't optional anymore.

Here are 10 of the biggest AI trends shaping 2026.

1. AI Agents Are Becoming Your Coworkers 🤖

The biggest shift isn't smarter chatbots.

It's AI Agents.

Instead of answering a single prompt, agents can:

Plan tasks
Search the web
Write code
Debug applications
Execute workflows
Talk to other agents
Remember context

Imagine saying:

"Build a REST API, deploy it to AWS, write tests, and create documentation."

And the AI completes the workflow.

This is rapidly becoming reality.

2. MCP (Model Context Protocol) Is Everywhere

MCP has become one of the hottest topics in AI.

Instead of manually connecting every tool to every AI model, MCP provides a common protocol.

Think of it as:

USB-C for AI.

One connection.

Many tools.

Developers can connect AI with:

GitHub
Slack
Databases
Figma
Jira
Notion
Local files
Custom APIs

Once connected, AI can understand and use those tools naturally.

3. AI Can Build Full Applications

A few years ago AI generated snippets.

Today it can generate:

Frontend
Backend
Database schema
Authentication
API documentation
Docker configuration
CI/CD pipelines

Developers are shifting from writing every line to reviewing and improving AI-generated code.

4. Multi-Agent Systems Are the Future

Instead of one giant AI...

Companies now use multiple specialized agents.

Example:

Research Agent
Coding Agent
Testing Agent
Deployment Agent
Documentation Agent

Each agent has one responsibility.

Together they complete complex software projects.

5. AI Memory Is Getting Smarter

Modern AI doesn't start from zero every conversation.

It can remember:

Preferences
Coding style
Previous projects
Team conventions
Frequently used libraries

This creates a much more personalized development experience.

6. AI Video Generation Is Exploding 🎥

Text-to-video quality has improved dramatically.

Developers can now generate:

Product demos
Tutorials
Marketing videos
Animations
Social media content

using only prompts.

Video creation is becoming as easy as writing Markdown.

7. Coding Is Becoming More Conversational

Instead of writing code first...

Developers describe what they want.

Example:

"Create a NestJS API with JWT authentication, MongoDB, Swagger, Docker support, and unit tests."

AI handles most of the boilerplate.

Developers focus on architecture and business logic.

8. AI Is Becoming Better at Debugging

Modern AI can:

Explain stack traces
Detect security issues
Suggest optimizations
Find race conditions
Review pull requests

It's becoming another reviewer on the team.

9. Small AI Models Are Winning Too

Bigger isn't always better.

Smaller models now offer:

Faster responses
Lower costs
Better privacy
Offline execution
Edge deployment

Many companies are using lightweight models for production workloads.

10. AI Is Becoming a Daily Development Tool

The biggest trend isn't a specific model.

It's adoption.

Developers now use AI for:

✅ Writing code

✅ Writing documentation

✅ Learning frameworks

✅ Refactoring

✅ Creating SQL queries

✅ Debugging

✅ Unit testing

✅ Code reviews

✅ Brainstorming

✅ Automation

AI is no longer an experiment.

It's becoming part of the standard development workflow.

Final Thoughts

The developers who thrive in 2026 won't be the ones who write the most code.

They'll be the ones who know how to collaborate effectively with AI.

AI isn't replacing developers.

It's changing what great developers spend their time on.

Learn the tools.

Experiment often.

Stay curious.

The future of software development is being built right now.

What excites you the most?

AI Agents?
MCP?
AI Coding?

🚀 7 Git Commands Every Developer Should Know (But Most Don't)

Darshan Raval — Wed, 15 Jul 2026 19:06:54 +0000

🚀 7 Git Commands Every Developer Should Know (But Most Don't)

If your Git workflow still looks like this...

git add .
git commit -m "fix"
git push

...you're leaving a lot of productivity on the table.

After working with Git every day for years, I realized that most developers only use about 20% of what Git can actually do.

Here are 7 Git commands that can save hours of debugging, make collaboration easier, and help you recover from mistakes like a pro.

1. `git reflog` — Your Git Time Machine 🕒

Have you ever accidentally deleted a branch, reset your commits, or messed something up?

Don't panic.

git reflog

This command shows every movement of your HEAD, including commits that don't even appear in your Git history anymore.

Example:

git reflog

Output:

a4b12cd HEAD@{0}: reset: moving to HEAD~1
7d9ef12 HEAD@{1}: commit: Added authentication

Recover it instantly:

git reset --hard HEAD@{1}

💡 Pro Tip: Before saying "I lost my code!", run git reflog.

It has saved countless developers more times than they'll admit.

2. `git bisect` — Find the Bug Automatically 🔍

Imagine your application worked yesterday.

Today?

Everything is broken.

Instead of checking 50 commits manually:

git bisect start
git bisect bad
git bisect good <last-working-commit>

Git will perform a binary search through your history.

After testing each suggested commit:

git bisect good

git bisect bad

Git keeps narrowing it down until it finds the exact commit that introduced the bug.

This turns:

"Let's check hundreds of commits..."

into

"Git found the problem in minutes."

3. `git stash` — Pause Your Work Without Committing 📦

You're halfway through a feature.

Suddenly:

"Can you quickly fix production?"

Instead of creating a messy WIP commit:

git stash

Switch branches.

Fix the issue.

Come back.

Restore everything:

git stash pop

Need multiple stashes?

git stash list

Preview changes:

git stash show -p

This command keeps your commit history clean while letting you multitask safely.

4. `git cherry-pick` — Copy One Commit, Not the Entire Branch 🍒

Suppose you fixed a bug on another branch.

Instead of merging everything:

git cherry-pick <commit-hash>

Git copies only that specific commit.

Perfect for:

Hotfixes
Production patches
Backporting fixes
Reusing code across release branches

It's one of the cleanest ways to move changes around.

5. `git blame` — Find Who Changed That Line 👀

Need to know who introduced a specific line?

git blame app.js

Output:

8c42f1d (Alex 2026-06-01) const apiUrl = ...

You'll see:

Author
Commit
Date
Exact line

This isn't about blaming teammates.

It's about understanding the context before changing code.

Most of the time you'll discover...

It was actually your own code from six months ago. 😅

6. `git log --oneline --graph --all` — Visualize Your Repository 🌳

Instead of reading endless commit history:

git log --oneline --graph --all

You'll get something like:

* 8ad32 Fix login bug
|\
| * 7bd21 Add dashboard
|/
* 91cd1 Initial commit

This helps you understand:

Branch structure
Merge history
Feature branches
Commit relationships

Especially useful when joining an unfamiliar project.

7. `git restore` — Undo Changes Without Losing Everything 🔄

Made changes you don't want?

Restore a file:

git restore index.js

Unstage files:

git restore --staged index.js

This is much safer than using confusing checkout commands.

Modern Git recommends restore because it's more explicit and easier to understand.

Bonus: The Command I Use Almost Every Day ⭐

git log --oneline --decorate --graph --all

It gives a beautiful overview of the repository with branch names and tags.

Once you start using it, it's hard to go back.

Quick Cheat Sheet

Command	Purpose
`git reflog`	Recover lost commits
`git bisect`	Find the commit that introduced a bug
`git stash`	Save work temporarily
`git cherry-pick`	Copy a single commit
`git blame`	See who changed a line
`git log --oneline --graph --all`	Visualize history
`git restore`	Undo changes safely

Final Thoughts

Git isn't just about commit and push.

The more you understand Git, the less time you'll spend fixing mistakes and the more confident you'll become when working on large codebases.

These commands have saved me countless hours while debugging production issues, reviewing code, and collaborating with teams.

If you're serious about becoming a better developer, start using at least one new Git command this week.

Your future self will thank you.

🚀 HTTP Just Got a New Method: Meet `QUERY` (And Why It Matters)

Darshan Raval — Tue, 14 Jul 2026 18:19:42 +0000

The HTTP protocol has remained surprisingly stable for years.

But now, there's a new method that every backend developer should know about: QUERY.

When I first heard about it, my reaction was simple:

"Wait... isn't GET enough?"

After digging deeper, I realized QUERY isn't trying to replace GET—it's solving a problem that developers have been working around for years.

Let's break it down.

🤔 The Problem with `GET`

For decades, GET has been the standard way to retrieve data.

Example:

GET /products?category=laptop&brand=apple&priceMin=50000&priceMax=150000&sort=price&order=asc&page=2

Simple.

Readable.

Cacheable.

But what happens when your search becomes more complex?

Imagine an e-commerce application where users can filter products by:

Multiple categories
Price ranges
Ratings
Availability
Brands
Colors
Sizes
Tags
Date ranges
Custom attributes

Suddenly your URL looks like this...

/products?category=laptop&brand=apple&brand=dell&brand=lenovo&rating=4&rating=5&color=black&color=silver&storage=512GB&storage=1TB&...

Not exactly beautiful.

😬 The Problems with Long URLs

Using GET for complex queries comes with several limitations.

1. URL Length Limits

Browsers, proxies, and servers all have practical limits on URL length.

Some support thousands of characters.

Some don't.

You don't want your API breaking because someone selected too many filters.

2. Sensitive Search Data

Everything inside a GET request lives in the URL.

That means it can appear in:

Browser history
Logs
Analytics
Reverse proxies
Shared links

Sometimes that's fine.

Sometimes it isn't.

3. Complex Objects Don't Fit Naturally

Imagine sending this using GET:

{
  "filters": {
    "category": ["Laptop", "Tablet"],
    "price": {
      "min": 50000,
      "max": 150000
    },
    "rating": [4, 5]
  }
}

It quickly becomes unreadable once converted into query parameters.

🤷 Why Not Just Use `POST`?

That's exactly what many APIs do today.

POST /products/search

Body:

{
  "filters": {
    "category": ["Laptop"],
    "rating": [4,5]
  }
}

Problem solved?

Not really.

The issue is semantic.

A POST request generally means:

"Something might change on the server."

Searching data doesn't modify anything.

It's simply reading.

Using POST for searching has always felt like a workaround rather than the perfect solution.

🎉 Introducing HTTP `QUERY`

The new QUERY method is designed specifically for safe read operations that require a request body.

Example:

QUERY /products
Content-Type: application/json

{
  "filters": {
    "category": ["Laptop"],
    "rating": [4,5],
    "price": {
      "min": 50000,
      "max": 150000
    }
  }
}

Looks much cleaner.

And much more expressive.

💡 Why `QUERY` Is Different

Unlike POST:

✅ It is intended for reading data
✅ It doesn't imply resource creation
✅ It doesn't imply updates
✅ It better matches API semantics

It says exactly what you're doing:

"I'm querying information."

📊 GET vs POST vs QUERY

Feature	GET	POST	QUERY
Read Data	✅	✅	✅
Safe Operation	✅	❌	✅
Request Body	❌	✅	✅
Large Filters	❌	✅	✅
Semantic for Search	✅ (simple)	😐	✅
Complex Queries	😐	✅	✅

🌍 Real-World Examples

Imagine building...

🛒 E-commerce

{
  "category": ["Electronics"],
  "brands": ["Apple","Samsung"],
  "price": {
    "min": 50000,
    "max": 150000
  }
}

🎬 Movie Platform

{
  "genres": ["Sci-Fi","Action"],
  "year": {
    "from": 2015,
    "to": 2025
  },
  "rating": 8
}

📈 Analytics Dashboard

{
  "dateRange": {
    "start": "2026-01-01",
    "end": "2026-12-31"
  },
  "groupBy": [
    "country",
    "device"
  ]
}

🤖 AI Search APIs

{
  "prompt": "Find Node.js tutorials published in the last month",
  "language": "English"
}

These requests are clearly queries, not updates.

⚠️ Can You Use It Today?

Not everywhere.

While the QUERY method has been standardized, support across browsers, frameworks, proxies, API gateways, and server infrastructure is still evolving.

That means many production systems will continue using:

GET for simple searches
POST for complex search bodies

for some time.

Think of QUERY as the direction HTTP is moving, not something that instantly replaces existing APIs.

🔥 Why This Matters

For years we've had this awkward situation:

GET couldn't carry a request body.
POST wasn't semantically correct for searching.
Developers had to choose the "least bad" option.

QUERY fills that gap.

It's one of those additions that feels surprisingly obvious once you see it.

💭 Should You Start Using It?

If you're building public APIs today...

Probably not yet.

Infrastructure support is still catching up.

But if you're a backend developer, API designer, or someone who enjoys understanding web standards, it's absolutely worth learning.

Today's "new" feature often becomes tomorrow's best practice.

🎯 Final Thoughts

HTTP doesn't evolve very often.

That's exactly why every new addition deserves attention.

Will QUERY replace GET?

No.

Will it replace every POST /search endpoint?

Probably not overnight.

But it gives developers something we've wanted for years:

A clean, semantic way to perform complex read operations.

And that's a pretty exciting step forward.

💬 What Do You Think?

Would you use the new QUERY method in your APIs?

Or do you think GET and POST are already enough?

🚫 Stop Using These Bad Coding Habits (Your Future Self Will Thank You)

Darshan Raval — Mon, 13 Jul 2026 20:12:31 +0000

Writing code is easy.
Writing code that your future self (or your teammates) won't hate is the real challenge.

Every developer starts with bad coding habits.

The problem isn't having them.

The problem is keeping them.

After reviewing countless repositories, working on production systems, fixing legacy code, and spending hours debugging simple mistakes, I've noticed the same habits appearing again and again.

Here are the biggest coding habits you should stop today.

1. ❌ Naming Variables Like `a`, `x`, `temp`, `data`

Bad:

const d = getData();
const x = d.filter((i) => i.active);

Better:

const users = getUsers();
const activeUsers = users.filter((user) => user.active);

Good variable names reduce the need for comments.

If someone needs to guess what a variable means...

...the name isn't good enough.

2. ❌ Writing Massive Functions

If your function takes two minutes to read...

It's too big.

Bad:

function processOrder() {
    // 250+ lines
}

Better:

validateOrder();
calculatePrice();
processPayment();
sendConfirmation();

Small functions are easier to:

Read
Test
Debug
Reuse

3. ❌ Copy-Pasting Code Everywhere

We've all done it.

Ctrl + C
Ctrl + V
Ctrl + C
Ctrl + V

Then one bug appears...

Now you have to fix it in 12 different places.

Instead:

Create utility functions
Extract reusable components
Follow the DRY principle

4. ❌ Ignoring Error Handling

Bad:

const user = await getUser(id);

Better:

try {
    const user = await getUser(id);
} catch (error) {
    console.error(error);
}

Production code always fails eventually.

Prepare for it.

5. ❌ Writing Comments for Obvious Code

Bad:

// Increment i
i++;

Good comments explain WHY, not WHAT.

Example:

// Retry because payment gateways occasionally timeout.

That's useful.

6. ❌ Hardcoding Everything

Bad:

const API_URL = "https://example.com/api";

Better:

const API_URL = process.env.API_URL;

Future deployments become much easier.

7. ❌ Never Refactoring

If your code works...

Great.

That doesn't mean it's good.

Every feature leaves technical debt.

Take time to clean it.

Future developers (including future you) will appreciate it.

8. ❌ Deep Nested Conditions

Bad:

if (user) {
    if (user.isVerified) {
        if (user.subscription) {
            if (user.subscription.active) {
                // do something
            }
        }
    }
}

Better:

if (!user) return;

if (!user.isVerified) return;

if (!user.subscription?.active) return;

doSomething();

Early returns make code dramatically easier to read.

9. ❌ Not Using a Linter or Formatter

Formatting manually wastes time.

Use tools like:

ESLint
Prettier

Consistency matters more than personal preference.

10. ❌ Skipping Tests Because "It Works"

"It works on my machine."

Every developer has said it.

Every developer has regretted it.

Even a few unit tests can prevent hours of debugging later.

Bonus Habit

❌ Not Reading Your Own Code

After writing a feature...

Close the editor.

Take a short break.

Come back 20 minutes later.

Read your code as if someone else wrote it.

You'll be surprised how many improvements you'll notice.

Remember

Clean code isn't about impressing other developers.

It's about making life easier for:

Your teammates
Your future self
Anyone who has to maintain your code

Programming isn't just about making computers understand.

It's about making humans understand.

💬 What Bad Habit Did You Finally Break?

I'd love to hear from other developers.

👇 What's one coding habit you stopped doing that made the biggest difference?

Darshan Raval — Sat, 11 Jul 2026 12:59:36 +0000

The Ultimate Claude Masterclass: 13 Power Features Changing the AI Game

Artificial Intelligence is no longer just about asking questions and getting text answers. Anthropic’s Claude has evolved from a simple chatbot into a fully autonomous, visual, and connected AI ecosystem. If you are still using it just to draft emails, you are barely scratching the surface.

Whether you are a developer, content creator, or business professional, here is your definitive guide to the 13 powerhouse features of Claude, packed with practical examples, formatted specifically for Dev.to.

🧩 Part 1: Smart Onboarding & Personalization

1. Introduction to Claude

Claude stands out in the crowded AI landscape because of its advanced reasoning, high emotional intelligence, and natural, human-like writing style. From parsing complex codebases to writing creative narratives, Claude feels less like a machine and more like a brilliant colleague.

2. Import Memory From ChatGPT To Claude

Switching platforms shouldn't mean losing your progress. With this feature, you can instantly migrate your entire persona, past context, and custom instructions from ChatGPT straight into Claude with a single click.

Example: If ChatGPT already knows your coding style or specific brand rules, importing it means Claude hits the ground running without you having to re-explain everything.

3. Add User Preferences

Tired of typing "Act as a Senior Developer" or "Keep it casual" in every single prompt? User Preferences lets you set permanent system-level instructions that Claude remembers across all new conversations.

Example: You can set a preference like: I manage a technology brand. Always keep explanations direct, modular, and optimized for scalability.

🎨 Part 2: Visuals, Coding & Apps

4. Create Apps & Artifacts Using Claude For Free

Claude’s Artifacts feature opens a dedicated, interactive window right next to your chat. When you ask Claude to write code, a webpage, or a game, it doesn't just show you lines of text—it renders it live.

Example: Prompt Claude to "Create a dynamic, interactive dashboard for tracking monthly expenses," and you can actually use the UI, click buttons, and test the app instantly in your browser.

5. Make Interactive Visuals

Gone are the days of static bar charts. Claude can transform raw data tables into rich, clickable, and interactive SVG or React-based visual elements.

Example: Paste your raw website analytics data and ask Claude for a visual breakdown; you’ll get an interactive chart where hovering over nodes reveals deeper metrics.

6. Make Beautiful Designs Using Claude Design

You don’t need to be a Figma pro to create stunning mockups. Claude Design introduces a dedicated visual canvas where you can instruct the AI to build, iterate, and polish user interfaces, web pages, and components in real time.

🔌 Part 3: Extensions & Next-Gen Workflows

7. Add Claude Chrome Extension

Bring AI directly to your browsing experience. The official Claude Chrome Extension allows you to summon Claude on any active webpage to summarize articles, explain complex documentation, or help you write emails without switching tabs.

Example: If you are reading a massive 50-page technical documentation page, open the extension and ask: "What are the exact authentication steps listed here?"

8. Web Search & Deep Research

Claude is no longer limited by a knowledge cutoff date. With real-time Web Search and Deep Research modes, it actively browses the live internet to aggregate current news, compile data, and cross-reference sources to deliver deeply analytical reports.

9. Connectors to Connect Apps

Claude integrates directly with your existing cloud stack. By using built-in Connectors, you can securely link Claude to tools like Google Drive, Notion, and GitHub, allowing the AI to read, analyze, and write data directly into your workspace.

🤖 Part 4: Autonomous Agents & Remote Execution

10. Execute Tasks Using Claude Cowork

This is where we cross into the future. Claude Cowork is an autonomous agent capable of using your desktop environment. It can move the cursor, open applications, fill out spreadsheets, and execute multi-step complex workflows entirely on its own.

11. Talk To Claude Remotely Using Dispatch

Away from your desk? Claude Dispatch acts as a remote control channel. You can securely message your home or office machine running Claude from your phone, instructing it to run heavy local scripts, download assets, or organize files while you are on the move.

12. Make Projects in Claude

For complex, ongoing work, the Projects feature lets you create dedicated environments. You can upload specific reference files, project briefs, and code repositories. Claude will then isolate its logic to focus only on the data relevant to that specific project.

13. Add Skills to Claude

You can permanently upgrade Claude's capabilities by teaching it custom Skills. By providing specific API tools or custom executable scripts, you enable Claude to perform advanced tasks—like video rendering triggers or server reboots—on command.
