I'm using bash for simple build problems like building dynamic component lists, when bash gets too unwieldy I switch to python. If the build process is stable enough and the scripts are beginning to get long, I'll rewrite the script as a CLI tool in a typed and compiled language.

Rinse and repeat.

The only thing that's really missing to me is bundling, which feels like a bit too big of a project to tackle on my own. But my current projects aren't big enough to need that, I'll pass that hurdle when it comes. And I may have to run webpack as a separate build process through node, but luckily I can do that in a CI container, and keep my dev machine clean.
