esbuild-mangle-unsupported

production.mangle on the esbuild adapter, which turns mangling off.

Message

A name in angle brackets is a value the message fills in.

[csszyx] esbuild-mangle-unsupported: The esbuild adapter does not support `production.mangle`, so class mangling is off for this build.
  help: use the Vite, Rollup or webpack plugin when the build needs mangled class names.
  note: emitted JS and CSS keep the original class names, so they still match.
