This comprehensive course teaches you how to implement Continuous Integration (CI) and Continuous Delivery (CD) with CircleCI. Starting with the fundamentals, you’ll understand what CI is, why it matters, and how it accelerates software development while reducing risks. The course covers setting up CircleCI for various projects, including web frameworks like Vue, React, Angular, and mobile platforms such as iOS and Android. You will learn how to configure pipelines using .circleci/config.yml, set up workflows, jobs, and reusable configuration patterns, and integrate with Docker for pre-built images. Practical lessons demonstrate unit testing with Jest, GitHub integration, running pull requests, and deploying applications securely and efficiently. Advanced topics include microservices CI/CD, scaling pipelines, automating artifact management, and leveraging tools like Rollbar, Postman, and AWS. You will also explore how major companies optimize their CI/CD workflows, troubleshoot common issues, and adopt best practices for team collaboration. By the end of this course, you will confidently set up, manage, and optimize CI/CD pipelines, enabling faster releases and higher-quality software.
