I was a huge CodePen fan in the past, but lately, I prefer my local development environment for creating quick demos and tryouts. I'm so used to my VS Code setup that I don't want to miss it.

To not fill my computer with random "throw away files", I usually create projects in the /tmp directory, test something out and forget about the files because they'll be deleted automatically.

Today I discovered the CodeSwing VS Code extension. It's like a local CodePen and precisely what I needed. It quickly spins up a demo environment, includes a snappy browser preview and automatically cleans up the files. It's beautiful!

Find CodeSwing on the VS Code marketplace or, if you want to learn more, read Bramus' blog post about it.
