usedIds

const Meta.usedIds: Set<string>;

A set of identifiers that are either present in the source code, or generated on the fly via generateId.

If you would like to for example introduce new variables to the source code, make sure to not give it a name that is already included in this set.

Example

Rolldown

import meta from "@monstermann/unplugin-meta/rolldown";

export default {
    plugins: [
        meta({
            resolve(node, meta) {
                console.log(meta.usedIds);
            },
        }),
    ],
};
