I was curious about how it works. It seems to be a wrapper for esbuild that transpiles typescript then calls your local node (it doesn't bundle nodejs). From https://tsx.is/faq https://tsx.is/faq : "tsx: Uses esbuild for fast compilation and does not perform type checking." From https://tsx.is/node-enhancement https://tsx.is/node-enhancement : "Under the hood, tsx calls node. This means the Node.js features supported in tsx depend on the Node.js version you have installed."
