If you're an API practitioner, this book will show you how to use Bruno to its maximum capacity for managing your API lifecycle . Bruno is a new alternative to Postman and Insomnia; this practical book will teach you how to use it for API design, development, testing, deployment, and monitoring . The book is less concerned with helping you become an API Management expert than it is with showing you how to make the most of Bruno's features so that you can efficiently complete tasks in the real world. The chapters cover topics such as creating a safe and scalable development environment, using the Bruno command line interface (CLI), and creating API blueprints with Bru Lang that are easy to understand and maintain. You'll learn how to embed business logic, manage data transformations, and implement robust error handling to build dynamic endpoints that respond to real-time events . In an effort to protect sensitive information, practical implementations of OAuth 2.0 authorization, JWT authentication, and effective secret management are implemented . Your API's reliability and scalability under different conditions can be further assured with automated testing and live debugging sessions . You can automate mundane tasks and expand your API's functionality with the help of the advanced integrations covered in this book. These integrations allow you to connect to popular platforms like AWS, Jira, GitHub, and Jenkins . Additionally, you will become an expert at configuring and executing webhooks and event-driven actions , which are crucial for keeping your API in sync with external systems. Key Learnings Use Bruno CLI via npm for simplified installation and guarantees an up-to-date API management toolkit. Create clear API blueprints for designing and building robust endpoints. Integrate JWT authentication for secure API access while supporting scalable, stateless user management practices. Integrate OAuth 2.0 for fine-grained authorization, and to control access to sensitive API resources. Implement secrets management via environment variables to protect credentials and maintains secure configuration. Implement automated test suites to validate API functionality across all endpoints. Carry out real-time debugging and logging of API interactions during live operations. Write custom automation scripts to streamline testing, deployment, and data management across API workflows. Integrate with third-party services like Jira, GitHub, Jenkins, and AWS. Work around webhooks and event-driven actions to respond real-time events.
