What Is a DTO? (And Why You Shouldn’t Return Your Entities in Spring Boot)

When building REST APIs with Spring Boot, it’s common to see beginners return entities directly from their controllers. At first glance, this seems fine—the data flows, the response looks right, and everything “just works.”

But what happens when your entity evolves? When sensitive fields accidentally get exposed? Or when lazy-loaded relationships break your JSON?

Getting Started with Spring Boot: Build a Task Manager App from Scratch

Spring Boot is the industry-standard framework for building modern Java applications. It dramatically reduces boilerplate code, accelerates development, and is battle-tested for microservices and monoliths alike. If you’re new to the Spring ecosystem, this post will walk you through everything you need to start building.

Building a Data Pipeline with Apache Camel: Processing Weather Data from AWS SQS

Learn how to build a scalable data pipeline with Apache Camel, AWS SQS, and PostgreSQL – Step by Step

Data pipelines are a critical part of modern software systems, ensuring seamless data flow between various components. In this tutorial, we’ll build an Apache Camel-based data pipeline that listens to an AWS SQS queue, retrieves weather information from the WeatherStack API, and persists the results into a PostgreSQL database.

How OAuth2 Differs from API Keys: Understanding Secure API Authentication

Learn the key differences between OAuth2 and API Keys for secure API authentication

In the ever-evolving landscape of software development, securing APIs is non-negotiable. With APIs acting as gateways to sensitive data and critical functionalities, choosing the right authentication method is crucial. Two common approaches dominate the field: API Keys and OAuth2.

What is an API? Understanding the Basics for Beginners

Learn what an API is, how it works, and why it’s essential for modern software development

In the world of software development, APIs (Application Programming Interfaces) are the unsung heroes. They power your favorite apps, connect systems behind the scenes, and enable modern digital experiences. Yet, for many beginners—whether you’re diving into front-end or back-end development—APIs can seem like an abstract concept.

The Evolution of System Integration: From SOAP to REST to Event-Driven Architectures

Explore the evolution of system integration: from SOAP to REST to Event-Criven Architectures

In the rapidly evolving landscape of software development, system integration has undergone a profound transformation. From the rigid structures of SOAP-based web services to the flexible, lightweight nature of RESTful APIs, and now the dynamic world of Event-Driven Architectures (EDA), integration patterns have continuously adapted to meet the demands of scalability, efficiency, and real-time data processing.

The Importance of API Security in Modern Software Integration

Discover common API security threats and best practices to protect your systems effectively

In today’s interconnected digital landscape, APIs (Application Programming Interfaces) are the backbone of modern software integration. They enable seamless communication between disparate systems, applications, and devices, powering everything from mobile apps to complex enterprise solutions. However, with this increased connectivity comes an equally significant risk: security vulnerabilities that can be exploited by malicious actors.
