This blog post discusses how to develop Node.js applications using Gitpod, a browser-based environment that provides the depth of a full local dev environment with VS Code but the friendly onboarding of JSFiddle. The author demonstrates how to write Node.js applications in this environment, run and debug them, work with Git for version control, automate Node.js setup, create pull requests, collaborate with others, and showcase applications. Gitpod is free for open-source development.
