Build tools are the dark arts of frontend development. Nobody fully understands them. Everyone pretends they do. And somehow, despite everything, the bundle gets built.

Every webpack config is a spell. Miss a comma and the whole thing collapses. Add the wrong plugin and your build time triples. Get it right and your application loads in under a second like magic.

This is not engineering. This is sorcery.

There are developers who understand build tools intuitively — who can look at a 200-line config and see exactly where the tree shaking is failing. These people are not normal. They are witches, and they should be respected.

If you are one of them, know that your power is rare and valuable. If you are not, know that it is perfectly acceptable to copy a config that works and never touch it again.

At the end of every configuration nightmare, every plugin conflict, every loader chain that makes no logical sense — the build either succeeds or it doesn’t.

And when it succeeds, when that green checkmark appears, you have done something that 90% of developers would have given up on.

Witchcraft, indeed.
