@swc/plugin-swc-magic

@swc/plugin-swc-magic processes magic annotations from the @swc/magic package, such as markAsPure, which annotates expressions so the SWC minifier can eliminate them as dead code during tree-shaking.

Usage

.swcrc:

{
  "jsc": {
    "experimental": {
      "plugins": ["@swc/plugin-swc-magic"]
    }
  }
}

markAsPure

import { markAsPure } from "@swc/magic";

markAsPure(() => console.log("This will be removed by the SWC minifier"));
