Testing AWS locally with LocalStack

Learn how to test SQS locally with LocalStack — cut costs, isolate tests, and speed up your development process

In today’s fast-paced development environment, testing is a crucial component that ensures the robustness and reliability of your applications. However, testing AWS services like SQS (Simple Queue Service) can be costly and cumbersome if done directly against live AWS environments. Enter LocalStack — a powerful tool that allows you to emulate AWS services locally, providing a cost-effective and isolated environment for testing.

OAuth2 Client Credentials Grant Type: When and How to Use It

Learn when and how to use OAuth2 Client Credentials for secure backend communication.

In the ever-evolving landscape of application security, OAuth2 has become a fundamental protocol for managing authorization. OAuth2 offers a range of grant types to accommodate different scenarios, each with its specific use cases. Among these, the Client Credentials Grant Type stands out for enabling secure communication between backend applications. This grant type is unique because it does not involve user interaction, making it ideal for system-to-system communication. In this post, we’ll explore what OAuth2 is, discuss the main grant types, and dive deep into when and how to effectively use the Client Credentials Grant Type.

Customizing Spring Boot Starter Templates

Streamline Spring Boot development with custom starters. Learn how to create, store, and use them.

Spring Boot’s starter templates have revolutionized how developers bootstrap new applications. They offer a quick and standardized way to include all necessary dependencies, making it easier to get a project up and running. However, as projects grow in complexity, the need for custom solutions becomes apparent. Creating custom Spring Boot starters allows you to tailor your development environment precisely to your project’s needs, ensuring consistency, reducing repetitive setup tasks, and streamlining the development process.

Advanced Configuration with Spring Boot: Profiles, Properties, and YAML
