Mastering Git

 Introduction to Git – Version Control Made Simple

What is Git?

Git is a distributed version control system that helps developers track changes in code, collaborate efficiently, and maintain project history.It was created by Linus Torvalds in 2005 to manage Linux kernel development.

Why Do We Need Git?

Before Git:

  • Code was shared via ZIP files 😬

  • No proper change tracking

  • Difficult collaboration

  • Frequent code overwrites

With Git:

  • Full change history

  • Branching and merging

  • Safe collaboration

  • Easy rollback

Centralized vs Distributed Version Control

Feature                Centralized (SVN)                Distributed (Git)
Internet required                Yes                    No
Local history                No                    Yes
Speed                Slower                    Faster
Branching                Hard                    Easy

Installing Git

Download from:

Verify installation:

git --version

Basic Git Workflow

git init
git add .
git commit -m "Initial commit"

Git Architecture

Git has 3 main areas:

  1. Working Directory

  2. Staging Area

  3. Repository

Git helps you:

  • Track changes

  • Collaborate efficiently

  • Maintain clean project history

Database Integration in FastAPI (SQLAlchemy CRUD)

  Introduction So far, we’ve built APIs without storing data.But real-world applications need a database to: Store user data. Manage products. Persist application state. In this blog, we’ll connect FastAPI with a database using SQLAlchemy and perform CRUD operations . What is SQLAlchemy? SQLAlchemy is a powerful Python ORM (Object Relational Mapper) that allows you to: Interact with databases using Python code. Avoid writing raw SQL queries. Work with models instead of tables. Step 1: Install Dependencies pip install sqlalchemy (For SQLite, no extra driver needed) Project Structure Update app/ ├── main.py ├── database/ │ ├── connection.py ├── models/ │ ├── item.py ├── schemas/ │ ├── item.py ├── routes/ │ ├── item.py Step 2: Database Connection app/database/connection.py from sqlalchemy import create_engine from sqlalchemy . orm import sessionmaker , declarative_base DATABASE_URL = "sqlite:///./test.db" engine = create_engine ( DAT...

Middleware & CORS in FastAPI

  Introduction As your API grows, you may need to: Log requests Modify responses Handle cross-origin requests This is where Middleware and CORS (Cross-Origin Resource Sharing) come into play.They help control how requests and responses flow through your application. What is Middleware? Middleware is a function that runs: Before a request reaches your route After a response is returned Think of it as a pipeline layer between client and server. Request Flow with Middleware Client → Middleware → Route → Middleware → Response Creating Custom Middleware from fastapi import FastAPI , Request import time app = FastAPI () @ app . middleware ( "http" ) async def log_requests ( request : Request , call_next ): start_time = time . time() response = await call_next ( request ) process_time = time . time() - start_time print ( f"Request: { request . url} | Time: { process_time } " ) return response What This Middle...
