points out in a comment below that VSCode is not the same as an IDE (which can be confusing, because Visual Studio is an IDE).

You asked, "Does VSCode support UML for Node.js? The answer to the question isn't black and white. I want to answer this question by showing readers, what UML support & UML tools are offered by VSCode, and what that really translates to in regards to UML tooling abilities. Updated 2021 - JUNE - 24th asked if I had any experience using Round-Trip Engineering in the comments section below - and I wont explain the details - but that question led me to realize that in order for my answer to be correct, I would need to edit out a couple inaccuracies." I have noticed though, despite my personal favorite UML tool being the Diagrams plugin for IntelliJ, many people who use IntelliJ still default to Plant UML, which has a version available for VS Code (maybe that's somthing to consider?)
NODE JS VISUAL STUDIO CODE FOR FREE
The question is specific to VSC ode, and the rest of this answer is specific to that, but I do want to mention, that though I use "JetBrains IntelliJ IDE Ultimate ed." the diagram plugin is available for free with the JetBrains community edition. After taking a couple semesters of Java GUI design, and doing some side work with JavaFX for a small business, I have found that, for professional, and production use, you can't beat IntelliJ. I love VS Code, but that doesn't mean I use VS Code for everything. So anyone that looks at my profile can tell I am a VS Code enthusiast.
