That’s what modern web development is like as long as you’re not using something like Next/React with a massive build process.
Which unfortunately, is what modern web development is.
Many stacks offer hot code reloading. I am not a dedicated frontend developer but I used to work on a Vue 3 frontend for a project and it was actually quite nice to have the dev service watch the files and the browser hot reload the page when I changed code in the editor. It's not all bad.
