Usage

These plugins are designed to be used programmatically from @swc/core.

const { transformSync } = require('@swc/core');
const {
  defaultRewriter,
  defaultUnwriter,
  // this is not being built or released until a need arises
  //noPropagationRewriter
} = require('@contrast/agent-swc-plugin');

const result = transformSync(src, {
  env: {
    targets: {
      node: '18', // specify your (lowest) node version
    },
  },
  jsc: {
    experimental: {
      plugins: [[defaultRewriter], { assess: true, inject: true }]],
    },
  },
});
