There are 5 modules in this course

This course equips developers with essential skills to test, debug, and scale APIs using NestJS. You will learn best practices for REST and GraphQL APIs, alongside strategies for building and managing microservices efficiently. These skills are critical for delivering robust, high-performance backend applications in professional software development environments.

By completing this course, learners will gain hands-on experience identifying and fixing bugs, implementing automated tests, and deploying scalable microservices. Practical exercises ensure you can apply these techniques to real-world projects, enhancing reliability and maintainability in production systems. What sets this course apart is its integration of theory with applied practice. Each topic combines conceptual understanding with guided coding exercises, enabling learners to immediately implement testing, debugging, and microservice patterns in live projects. This course is ideal for backend developers, software engineers, and technical leads who have prior experience with Node.js or NestJS fundamentals. Familiarity with JavaScript/TypeScript and basic API design concepts is recommended. This course is part two of a three-course Specialization designed to provide a comprehensive learning pathway in this subject area. While it delivers standalone value and practical skills, learners seeking a more integrated and in-depth progression may benefit from completing the full Specialization.

This module guides learners through the essentials of testing and debugging REST APIs in NestJS, covering both unit and integration testing strategies. You will learn how to measure test coverage, write effective test cases, and utilize debugging tools to ensure your APIs are reliable and maintainable.
