Usage

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

`js
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 }]],
},
},
});
`

Releasing

Run npm version to bump the version. Push the changes
and tag to the repo.

When the version bump is merged to main, invoke the release workflow using
either the GitHub UI or the gh` CLI program.
