JavaScript is a dynamic programming language used here with Node.js to build a basic web application. The application provides a practical target for learning repeatable deployment. section 2.0
A small JavaScript web application connects several practical tools:
- Express.js handles the request-response cycle and maps functions to URLs and HTTP methods. section 2.5
- Node.js provides the runtime, while npm initializes projects and manages their packages. section 2.0
- package.json tracks JavaScript dependencies, helping create a repeatable and consistent environment. section 2.5
- Git tracks code changes and supports sharing, maintenance, and later deployment automation. section 2.5
A deployment path
Build a simple JavaScript/Node.js web application with Express.js, track it with Git, package its dependencies, and progressively move it toward containers and Kubernetes deployment. section 1.2 section 2.0
