⚙️ Implementation Guide¶

Implementation is where your idea turns into reality. For a Mini Project, move fast but keep your code clean.

🏗️ Architecture & Planning¶

Before you start typing npm install, draw your system out!

1. Database Schema¶

Even for small projects, use tools like dbdiagram.io or draw.io to map out your tables/collections. * Clearly define Primary Keys and Foreign Keys. * Decide between SQL (MySQL/Postgres) or NoSQL (MongoDB/Firebase).

2. UI Wireframes¶

Don't design as you code. * Use Figma (or even a pen and paper) to sketch the screens. * Define the flow: "If user clicks button A, they go to page B."

💻 The Build Phase¶

Step 1: Initialize Git¶

Don't be the student who loses their project because their laptop crashed.

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

Step 2: Environment Setup¶

• Use .env files for secrets (API Keys, DB Passwords).
• Create a requirements.txt (Python) or package.json (JS) to track libraries.

Step 3: Core Logic First¶

Build the functionality before the "looks." * Good: "User login works and data is saved to DB." * Bad: "The login button has a beautiful hover effect but doesn't actually log anyone in."

🧪 Testing Your Work¶

• Unit Testing: Check if individual functions work.
• Integration Testing: Check if the Frontend talks to the Backend properly.
• Boundary Testing: What happens if a user enters a negative number or a very long string?
