Welcome to the Developer’s Handbook! During my internship, I initially struggled with navigating official documentation and articles. It took some time to connect the dots, but once I grasped the core concepts, these became reliable sources I could always refer back to. Whether you’re just starting out or looking to refresh your knowledge, this guide of resources covers the key concepts, methodologies, and tools that are fundamental to get started with software engineering.

1. Software Development Life Cycle (SDLC) and Agile Methodology

a. Overview of SDLC

The Software Development Life Cycle (SDLC) is a structured process used by software developers to design, develop, and test software.

• Introduction to SDLC
• Detailed Guide on Software Development

b. Agile Software Development

Agile is a methodology focused on iterative development, where requirements and solutions evolve through collaboration between organising cross-functional teams.

• Introduction to Agile Software Development
• Agile Practice Guide
• Understanding Agile Methodology

c. Extreme Programming (XP)

Extreme Programming (XP) is an Agile software development framework that aims to improve software quality and responsiveness to changing customer requirements through frequent releases in short development cycles.

• Introduction to Extreme Programming
• 12 Core Practices in XP

2. Version Control with Git

Git is a distributed version control system that helps developers track changes in their codebase, collaborate with others, and manage different versions of their projects.

• Git Documentation

3. Semantic Versioning

Semantic Versioning is a versioning scheme for software that uses a three-part version number (major, minor, patch) to indicate backward-incompatible changes, backward-compatible changes, and bug fixes.

• Semantic Versioning Guide

4. Programming Languages and Object-Oriented Design

To make things clearer, here’s a breakdown of programming languages and related principles:

a. Object-Oriented Design Principles (SOLID)

The SOLID principles are a set of five design principles intended to make software designs more understandable, flexible, and maintainable. They are key to OOP (object-oriented programming) and are widely applied in software engineering.

• Understanding SOLID Principles
• Single Responsibility Principle
• Complete Guide to SOLID Principles

b. Backend with Java Spring Boot
Backend languages focus on the server-side logic and data processing.

Java
Java is widely used for enterprise applications and has a strong emphasis on object-oriented programming.

• Java Basics

c. Frontend with React and Typescript

Frontend languages are used to build user interfaces, making applications interactive and visually engaging.

JavaScript Arrays

Arrays are a fundamental part of JavaScript, allowing you to store and manipulate lists of values.

• JavaScript Arrays Documentation

TypeScript

TypeScript is a superset of JavaScript that adds types, interfaces, and other language features that help in writing more robust and maintainable code.

• TypeScript Handbook

React: Tic Tac Toe Tutorial

React is a JavaScript library for building user interfaces. This section guides you through a simple Tic Tac Toe game to get started with React.

• React Tic Tac Toe Tutorial
• Breaking UI into Components

5. Object-Relational Mapping (ORM)

ORM is a programming technique that enables you to query and manipulate data from a database using an object-oriented paradigm.

• Java Persistence API (JPA) Tutorial
• Hibernate ORM Tutorial

6. Spring JPA

Spring Data JPA is a part of the Spring Framework that simplifies the data access layer of an application, providing easy-to-use methods for accessing and modifying data.

• Spring Data JPA Guide

7. REST APIs

Representational State Transfer (REST) is an architectural style for designing networked applications. RESTful APIs allow different software applications to communicate with each other over the internet using standard HTTP methods.

• What is a RESTful API?
• Understanding and Using REST APIs

8. HTTP Methods

HTTP methods are a set of request methods used in web development to interact with resources on the internet.

• HTTP Methods Explained

9. Unit Testing

Unit testing is a software testing method where individual units or components of a software are tested. It ensures that each unit of the software performs as expected.

• Introduction to Unit Testing
• Best Practices for Unit Testing for Frontend
• Best Practices for Unit Testing in Java

10. JSON Web Tokens (JWT)

JWT is a compact, URL-safe means of representing claims to be transferred between two parties.

• Introduction to JWT

11. CSS and Frameworks

CSS is essential for styling web applications. Consider exploring Bootstrap for rapid UI development.

• Bootstrap Documentation
• Styling React Components

12. Data Modeling

Data modeling is the process of creating a data model for the data to be stored in a database. It helps in organising and structuring data to support business processes.

• Overview of Data Modeling
• Data Models in DBMS
• ER Model Concepts
