You’ll start with the fundamentals of Continuous Integration (CI), understanding why it is critical for modern development workflows. The course dives into practical unit testing techniques using Jest and setting up CI pipelines with GitHub. Developers will gain hands-on experience with Node.js and React projects, including database integration and Docker image builds. Lessons also cover setting up workflows, jobs, reusable configuration, and leveraging .circleci/config.yml for streamlined automation. Advanced topics include microservices CI/CD, artifact management, and integrating tools like Postman, Rollbar, and AWS for full-stack deployment. By the end, learners will be able to implement robust CI/CD pipelines, reduce deployment errors, and ship high-quality software faster across web and mobile platforms.
