How to use the @babel/template.default.expression function in @babel/template

const exportTemplate = template(`
  exports.REMOTE = LOCAL;
`);

/**
 * Flags the exported module as a transpiled ES module. Needs to be kept in 1:1
 * compatibility with Babel.
 */
const esModuleExportTemplate = template(`
  Object.defineProperty(exports, '__esModule', {value: true});
`);

/**
 * Resolution template in case it is requested.
 */
const resolveTemplate = template.expression(`
  require.resolve(NODE)
`);

/**
 * Enforces the resolution of a path to a fully-qualified one, if set.
 */
function resolvePath(node: {value: string, ...}, resolve: boolean) {
  if (!resolve) {
    return node;
  }

  return resolveTemplate({
    NODE: node,
  });
}
