I used the .wasm directly. Create the set which will contain user inputs , and put features which you want in the set. @yisibl 

const ptr = exports.hb_subset_input_create_or_fail();
const layoutFeatures = exports.hb_subset_input_set(
      ptr,
      6 /** HB_SUBSET_SETS_LAYOUT_FEATURE_TAG **/
  );
exports.hb_set_add(layoutFeatures,hb_tag('smcp'));  // hb_tag function is in the source code of hb.js
