@ucimo there are two plugins for vscode to preview jscad designs on the market.
Also you can edit your script in vscode and drag drop the file to https://openjscad.xyz after enabling auto-reload there. It will not work for typescript out of the box, but you can setup esbuild to bundle into js file and drag drop that file in openjscad for preview.
There is also https://jscad.app that is not yet official, it is a protoype for new jscad preview/edit . It supports typescript (transpiles it on the fly) and has some perf improvements too. If you feel chatty you can join the jscad discord channel also.
