Day 4 of 100daysofcode : RESTful API Integration

What I Built:

Today, I learned about RESTful APIs and implemented an endpoint in my e-commerce project to fetch a list of products from the backend. I also explored how the frontend interacts with the backend to display this data dynamically.

What I Learned:

What are RESTful APIs?

REST stands for Representational State Transfer, which is a design pattern for creating scalable web services.
A RESTful API allows communication between a client (frontend) and a server (backend) using HTTP methods such as:
GET: Retrieve data.
POST: Send data to the server.
PUT/PATCH: Update existing data.
DELETE: Remove data.

How RESTful APIs Work:

The backend exposes endpoints (URLs) that the frontend can call to perform specific actions.
For example:

Backend endpoint: /api/products (fetch all products).
Frontend calls this URL using an HTTP GET request and receives a list of products in JSON format.
The client then uses this data to render it visually in the user interface.

Key Takeaways:

RESTful APIs allow seamless communication between the frontend and backend.
Learned how to fetch data using the fetch API in React and dynamically render it.
MongoDB Compass is a helpful tool for adding and managing data during development.

Below is an example of how I fetch API from backend:

Day 7 of 100daysofcode : A Deep Dive into Authentication

Today’s focus was on a crucial aspect of user authentication. I built an authentication flow using the MERN stack (MongoDB, Express, React, Node.js). Here’s a breakdown of what I accomplished:

1-Backend (Node.js/Express):
-User Registration: Created API endpoints for user registration, receiving user data (username, password).
-Password Hashing (bcrypt): Instead of storing passwords directly in the database (which is a major security risk), I used bcrypt to hash passwords. Hashing transforms the password into a one-way string of characters, making it virtually impossible to reverse engineer the original password even if the database is compromised.
-JWT (JSON Web Tokens): After successful login, the server generates a JWT. This token is a compact, self-contained way to securely transmit information between parties as a JSON object. It contains information about the user (e.g., user ID) and is digitally signed, ensuring its integrity.
-Protected Routes: Implemented middleware to protect specific API routes. Only requests with a valid JWT in their header are allowed to access these routes.

2-Frontend (React):
-User Interface: Created forms for user registration and login.
-API Calls: Used axios to make API requests to the backend for registration and login.
-Token Storage: After successful login, the JWT is stored in the browser (local storage).
-Authorization: Included the JWT in the Authorization header of subsequent API requests to access protected resources.

3-Database (MongoDB):
-User Model: Created a schema to store user information, including the hashed password.

Why is this important?

Authentication is essential for securing web applications. It verifies the identity of users, preventing unauthorized access to sensitive data and functionalities. Using bcrypt for hashing and JWT for authorization are industry best practices for building secure authentication systems.

4-Example (Simplified flow):

User submits login credentials on the React frontend.
The frontend sends a request to the backend.
The backend verifies the credentials and generates a JWT.
The backend sends the JWT back to the frontend.
The frontend stores the JWT.
For subsequent requests to protected routes, the frontend includes the JWT in the Authorization header.
The backend verifies the JWT before granting access.

Day 8 of 100daysofcode : CRUD Operations

Today, I delved into CRUD operations (Create, Read, Update, Delete) and how they power the interaction between the frontend and backend in my outdoor adventure gear store project. Here’s a closer look at how each operation works and connects the two sides:

1-Create (Adding New User):
-Frontend: I built a Sign-up form using React. When a user fills in regististration details like username, email, phone number, and password, the form data is validated and submitted.
-Backend: A POST request is sent to the server’s /api/users endpoint. The backend (Node.js and Express) processes the request, validates the data, and inserts a new user document into MongoDB.
-Database: MongoDB generates a unique ID for the user and stores it with all the submitted details.

2-Read (Displaying Products):
-Frontend: Users can browse products on the store’s product page. I used React to dynamically display product data in cards with options to filter and search.
-Backend: When the frontend sends a GET request to /api/products, the server queries MongoDB for the product list. The results are sent back as JSON.
-Integration: React uses the fetched data to render a responsive UI, ensuring users see updated products immediately.

3-Update (Editing Product Details):
-Frontend: Admins can select a product to edit, triggering a pre-filled form with the product’s current details. Upon submitting the updated data, a PUT request is sent to /api/products/:id.
-Backend: The server retrieves the product by its ID, updates the necessary fields in the MongoDB document, and responds with the updated product data.
-Integration: The frontend reflects the changes immediately, ensuring the UI stays in sync with the database.

4-Delete (Removing Products):
-Frontend: Admins can click a Delete button on a product card, confirming their action through a dialog box. This triggers a DELETE request to /api/products/:id.
-Backend: The server locates the product in MongoDB using its ID and removes it from the database.
-Integration: The frontend dynamically removes the deleted product from the displayed list without requiring a page refresh.

Key Learnings:

Properly structured API endpoints are crucial for seamless communication between the frontend and backend.
Using state management in React ensures data updates are reflected in real time.
Error handling at both the frontend and backend ensures users are notified of any issues.

CRUD operations are the backbone of any dynamic application, and building them has deepened my understanding of how the frontend and backend collaborate to manage data. It’s exciting to see how each part fits together!

Day 13 of 100daysofcode : The Importance of Gantt Charts in Project Management

Managing projects can feel overwhelming, especially when you’re juggling multiple tasks, deadlines, and team members. This is where Gantt charts come in—a simple yet powerful tool that helps you organize your project visually.

A Gantt chart is like a timeline that breaks your project into smaller tasks. Each task is represented by a bar, showing when it starts and ends. These bars are arranged along a calendar, making it easy to see the order of tasks and how long each one will take. Arrows or lines between tasks show dependencies—meaning which tasks need to be completed before others can begin.

Why Are Gantt Charts Important?

Clear Project Overview: Gantt charts give you a bird’s-eye view of your project. You can see all the tasks, their deadlines, and how they connect, which helps you stay organized.
Improved Time Management: With a clear timeline, you can plan your work better and avoid last-minute rushes. It also helps you prioritize tasks that are more urgent.
Better Team Coordination: Everyone on the team can see the project timeline, understand their responsibilities, and know how their work affects others. This improves communication and reduces confusion.
Tracking Progress: Gantt charts make it easy to track which tasks are done, which are in progress, and which are delayed. This helps you adjust your plan if something isn’t going as expected.
Identifying Dependencies: You’ll know which tasks depend on others, so you can avoid bottlenecks or delays caused by missing a step.

Example: Using ClickUp for Gantt Charts

ClickUp is a friendly tool that includes a Gantt chart feature. It allows you to:

Create Tasks Easily: Add tasks and set start and due dates with just a few clicks.
Drag and Drop Adjustments: If a deadline changes, you can adjust your Gantt chart by dragging tasks to new dates.
Track Progress Visually: Completed tasks are marked on the chart, so you always know how much work is done.
Set Dependencies: You can link tasks to show which ones need to be finished before others can start.

For example, if you’re working on a software project, you might have tasks like “Design UI”, “Develop Backend”, and “Test Features.” Using a Gantt chart in ClickUp, you can see the order of these tasks, assign deadlines, and adjust as needed if one step takes longer than expected.

Below is a simple example that illustrate how we use Gantt chart in ClickUp:

Day 14 of 100daysofcode : SOLID Principles in Software Development

Today, I’m diving into SOLID principles, a cornerstone of clean and maintainable software design. Let’s break them down with more details and relatable real-life examples:

What Are SOLID Principles?

SOLID is an acronym for five design principles that help developers write scalable, robust, and maintainable code. Here are the principles:

1.1. S - Single Responsibility Principle (SRP):
-Definition: A class should have only one responsibility or reason to change.
-Real-life example: Imagine a library system. A class that handles book inventory should not also handle user membership. If the library decides to change its membership policy, it shouldn’t affect how books are managed.
1.2. O - Open/Closed Principle (OCP):
-Definition: Software entities should be open for extension but closed for modification
-Real-life example: Consider an online shopping platform where new payment methods (like Apple Pay or Google Pay) are introduced. Instead of modifying the existing payment processing system, you can extend it by adding new modules for each payment method.
1.3. L - Liskov Substitution Principle (LSP):
-Definition: Subtypes must be substitutable for their base types without altering the correctness of the program.
-Real-life example: In a ride-sharing app, a base class Vehicle could have subtypes like Car, Bike , or Electric Scooter . Any vehicle should work seamlessly within the app’s logic, regardless of its type.
1.4. I - Interface Segregation Principle (ISP):
-Definition: A class should not be forced to implement interfaces it does not use.
-Real-life example: Think of a smart home system. A light bulb controller interface should not require methods to control a thermostat. Each device should have its own specific interface.
1.5. D - Dependency Inversion Principle (DIP):
-Definition: High-level modules should not depend on low-level modules; both should depend on abstractions.
-Real-life example: In an e-commerce platform, the order processing system (high-level module) should depend on an abstraction of a payment gateway rather than directly on a specific provider like PayPal. This allows for easily swapping providers without affecting the rest of the system.

Benefits of Applying SOLID Principles:

2.1. Improved Code Quality: Makes code cleaner and more understandable.
2.2. Ease of Maintenance: Reduces the cost and complexity of modifying code.
2.3. Enhanced Scalability: Supports the addition of new features without disrupting existing ones.
2.4. Minimized Bugs: Promotes writing predictable and robust systems.

By integrating these principles into your development practices, you’ll build software that’s easier to manage and scale in the long run.

Day 15 of 100daysofcode : The Power of Planning - Avoiding Coding Chaos

Today’s lesson comes from a hard-earned experience: the critical importance of planning before you start coding. Early in my coding journey, I jumped into a project, full of enthusiasm, without a clear plan. Let’s just say it was a learning experience !

I was so eager to bring my idea to life that I skipped the planning phase entirely. I started writing code immediately, adding features as they popped into my head. It felt great initially, like building something from scratch. However, as the project grew in complexity, things started to unravel.

The Conflict:

The biggest problem I encountered was when I tried to integrate a new, seemingly simple feature. Because I hadn’t thought about the overall architecture, my existing code was completely incompatible with the new functionality. I was forced to refactor large portions of the codebase, a task that was significantly more difficult and time-consuming than if I had planned for it from the beginning. It was a frustrating reminder that coding without a roadmap can lead to a tangled mess.

The Lesson:

This project taught me a vital lesson: Planning is the foundation of successful software development. Before writing a single line of code, it’s essential to:

Clearly Define the Scope: Determine exactly what your project will and won’t do. Setting boundaries early prevents scope creep and keeps your project manageable.
Design the Architecture: Think about how the different parts of your project will interact. A simple diagram or even a list of components can be incredibly helpful. Consider data flow and how information will be stored and accessed.
Anticipate Future Needs: Imagine how your project might evolve. What features might you want to add later? Planning for potential future expansions will influence your initial design choices and prevent costly rewrites down the line.
Develop Scenarios/User Stories: Describe how users will interact with your project. Think about the steps they’ll take, the information they’ll need, and the outcomes they’ll expect. This helps uncover potential usability issues and edge cases early on.

Example of Scenarios:

Let’s say I was building a simple cart management tool. Some example scenarios I should have considered are:

“As a user, I want to be able to add new items to the cart, specifying their name, quantity, and price…”
“As a user, I want to be able to generate a report of all items in the cart.”
“As a user, I want to be able to update the quantity of an existing item.”

By planning and writing these scenarios, I would have identified the need for a database, search functionality, reporting capabilities, and update mechanisms before I started writing code. This would have saved me from having to drastically restructure my project later.

Moving Forward:

Now, I always take the time to plan before I start coding. It might seem like it slows me down initially, but it actually saves me a lot of time and frustration in the long run. Planning isn’t just about preventing conflicts; it’s about creating cleaner, more maintainable, and ultimately more successful projects.

Day 16 of 100daysofcode : The Importance of Data Flow Diagrams (DFDs) in Software Development

Hey everyone! Today, let’s talk about Data Flow Diagrams (DFDs) and why they’re so important in the software field. If you’re new to software development, this is a great concept to understand early on!

What is a Data Flow Diagram (DFD)?

A DFD is a visual representation of how data moves through a system. It shows:

Processes: What happens to the data (e.g., calculations, transformations).
Data Stores: Where data is stored (e.g., databases, files).
External Entities: Sources or destinations of data (e.g., users, other systems).
Data Flows: The paths data takes between processes, stores, and entities.

Think of it as a map that shows how information travels and gets processed in a system.

Why Are DFDs Important?

Clarity and Understanding: DFDs help developers, stakeholders, and team members understand how a system works without diving into code.
Identify Issues Early: By visualizing data flow, you can spot inefficiencies, missing processes, or redundant steps before coding begins.
Communication Tool: It’s a great way to explain complex systems to non-technical stakeholders.
Blueprint for Development: DFDs act as a guide for developers, ensuring everyone is on the same page about how data should flow.
Documentation: They serve as a reference for future updates or debugging.

Example of a Simple DFD

Imagine a login system:

External Entity: User enters credentials.
Process: System validates the credentials.
Data Store: Checks against the user database.
Data Flow: Returns success or error messages to the user.

Tips for Beginners:

Start with a Level 0 DFD (high-level overview) and break it down into more detailed levels.
Use tools like Lucidchart, Dia, or even pen and paper to create DFDs.
Keep it simple and focus on the flow of data, not the implementation details.

DFDs are a foundational tool in software development, helping you design better systems and communicate effectively. If you’re just starting out, practicing DFDs will make you a better problem-solver and system thinker!

Day 19 of 100daysofcode : Implementing Pagination with a “Load More” Button in Node.js

Today, I tackled pagination by implementing a “Load More” button for a product category in my Node.js backend!

Here’s what I did:

Backend:

Built an API endpoint in Node.js that fetches 6 products at a time for a specific category.
Used query parameters (page and limit) to control which products are returned.

Frontend:

Added a “Load More” button that fetches the next 6 products when clicked.
Updated the UI dynamically without reloading the page.

Why Pagination Matters:

Performance: Fetching only 6 products at a time reduces load on the server and speeds up the initial page load.
User Experience: Users can explore more products without being overwhelmed by a long list.
Scalability: This approach works seamlessly even with thousands of products.

Day 20 of 100daysofcode : Scaling a Web Application

What is Scaling?

Scaling refers to increasing the capacity of a web application to handle more users, traffic, and data efficiently. A well-scaled application remains fast, responsive, and reliable even under high demand.

Types of Scaling

2.1. Horizontal Scaling (Scaling Out):

Adds more servers or instances to distribute the load.
Used by cloud providers like AWS, Google Cloud, and Azure.
Example: A load balancer distributes traffic between multiple servers.

2.2. Vertical Scaling (Scaling Up):

Upgrades the existing server’s CPU, RAM, or storage to handle more traffic.
Easier but has a limit (hardware constraints).
Example: Increasing RAM from 8GB to 32GB on a server.

2.3. Auto Scaling

Dynamically adds or removes resources based on demand.
Example: AWS Auto Scaling increases instances when traffic spikes.

Why is Scaling Important?

3.1. Handles High Traffic: Prevents crashes when user numbers increase.
3.2. Improves Performance: Faster response times, better user experience.
3.3. Cost-Effective: Pay for resources only when needed (cloud-based scaling).
3.4. Ensures Reliability: Reduces downtime by distributing load.

How to Scale Your MERN App?

4.1. Use Nginx as a reverse proxy to distribute traffic.
4.2. Store session data in Redis instead of memory.
4.3. Deploy on AWS or DigitalOcean with auto-scaling.
4.4. Optimize database with indexes and sharding.
4.5. Use CDN for serving static assets (images, CSS, JS).

Conclusion:

Scaling is essential for building high-performance, cost-effective, and reliable web applications. Understanding when to use horizontal vs vertical scaling, caching, load balancing, and database optimization helps ensure your app runs smoothly, even with millions of users.

Day 21 of 100daysofcode : JavaScript vs. TypeScript: Key Differences Explained

JavaScript and TypeScript are both widely used in web development, but they have distinct differences. Let’s break them down!

What is JavaScript?

JavaScript (JS) is a dynamically typed scripting language that runs in web browsers and servers (Node.js). It is the foundation of modern web applications and allows developers to create interactive websites.

1.1. Key Features of JavaScript:

Interpreted at runtime, making it flexible.
Supports event-driven, functional, and object-oriented programming.
Dynamically typed: Variable types are determined at runtime, which can sometimes lead to unexpected errors.
Widely used in frontend frameworks (React, Vue, Angular) and backend (Node.js).

What is TypeScript?

TypeScript (TS) is a superset of JavaScript developed by Microsoft that adds static typing and additional features to enhance JavaScript’s capabilities. It compiles down to plain JavaScript, meaning it can run anywhere JS runs.

2.1. Key Features of TypeScript:

Statically typed: Detects errors at compile time instead of runtime.
Supports interfaces and generics: Helps in writing scalable and maintainable code.
Improved tooling support: Provides better IntelliSense, autocompletion, and debugging in IDEs.
Object-oriented features: Includes concepts like classes, interfaces, and modules.

Final Thoughts

TypeScript is becoming the preferred choice for large applications because of its safety, scalability, and enhanced developer experience. However, JavaScript remains a core language for web development, especially for smaller projects and quick development cycles.

Day 22 of 100daysofcode : The Power of Node.js in Backend Development

In modern web development, the backend plays a crucial role in handling user requests, managing data, and ensuring a smooth experience for users. One of the most popular choices for backend development today is Node.js, and here’s why!

Why Node.js for Backend?

Node.js is a fast, lightweight, and scalable JavaScript runtime that is well-suited for handling large amounts of data and high-traffic applications. Here are some key advantages:

Asynchronous & Non-blocking: Unlike traditional synchronous languages, Node.js operates on an event-driven architecture. This allows it to handle multiple requests at the same time without slowing down.
Scalability: It can handle thousands of concurrent connections, making it ideal for real-time applications like e-commerce websites, chat apps, and live dashboards.
Single Programming Language: With Node.js, you can use JavaScript for both frontend (React) and backend, reducing development complexity.
Strong Ecosystem: The npm (Node Package Manager) has thousands of libraries that speed up development, from authentication to database management.

Why Do We Use Express.js?

While Node.js is powerful, it doesn’t provide built-in tools for handling routing, middleware, or request handling efficiently. That’s where Express.js comes in!

Express.js is a lightweight framework for Node.js that makes building backend applications easier and faster. Here’s why we use it:

Simplified Routing: Instead of manually handling requests, Express.js provides an easy way to define routes (GET, POST, PUT, DELETE).
Middleware Support: Allows us to add authentication, logging, error handling, and request processing without modifying core logic.
Optimized Performance: Express.js is built to handle high traffic efficiently, making it great for e-commerce applications.
Integration with Databases: Works seamlessly with MongoDB, PostgreSQL, and other databases for data management.

Is Node.js Fast Enough for Handling Large Data?

Yes! But only if used correctly. Handling large data involves optimizing the backend, database, and server architecture. Here’s how you can make it even faster:

Efficient Database Queries: Use MongoDB with proper indexing to speed up queries and avoid performance bottlenecks.
Redis Caching: Store frequently accessed data in Redis to reduce repeated database calls.
Load Balancing & Clustering: Scale your Node.js app horizontally to distribute traffic across multiple instances.
Asynchronous Processing: Offload heavy tasks like image processing, email sending, and background jobs using BullMQ or RabbitMQ.
Use a CDN for Images: Services like Cloudinary or AWS S3 ensure that large images don’t slow down your website.

Final Thoughts

Node.js, combined with Express.js, provides a high-performance, scalable, and developer-friendly backend solution. It’s widely used in e-commerce, real-time applications, and APIs because of its speed and efficiency.

However, optimization is key to ensuring fast load times and seamless user experiences.

Would you choose Node.js and Express.js for your next backend project?
