CI/CD in Node.js with GitHub Actions

Continuous integration and continuous deployment (CI/CD) are software engineering practices that facilitate collaboration and enhance software quality by ensuring frequent, small code updates and automated deployment processes. GitHub Actions is a platform that enables developers to automate their build, test, and deployment pipelines directly in a GitHub repository, without needing external platforms. The tutorial outlines how to set up a CI/CD pipeline for a Node.js project using GitHub Actions, explaining the creation and configuration of workflows, jobs, and steps within a YAML file. It highlights the advantages of CI/CD, such as simpler fault isolation, improved code quality, and shorter code review times, and demonstrates how to implement a CI/CD pipeline that automatically deploys a Node.js application to Heroku. GitHub Actions provides a marketplace with pre-built actions that can be customized, allowing developers to efficiently create and manage workflows tailored to their project's needs.
