Most of the websites I write these days don’t have a build step for development, only for production. Modern browsers (and modern node) support ES modules, so there is no need to build anything until you ship to a legacy browser. The only pain point of not building during development is when I need to pull in a third party dependency (since node and browsers pull from different sources; and import-maps is not is still not a standard), but if your are not using any third party dependencies, you should be fine.
