I try to mixin a widget js file following guide at here. I create a file requirejs-config.js in view/frontend directory. There’s view/frontend/requirejs-config.js:

var config = {    config: {       mixins: {           'mage/dataPost': {               'Vendor_Training/js/dataPost-mixin': true           }       }    } }; 

And there’s view/frontend/web/js/dataPost-mixin.js:

define([   'jquery' ], function($  ) {     console.log('Mixin Working');     return function (dataPost) {        return dataPost;     }; }); 

And it’s exist on pub/static/frontend/<Vendor>/<theme>/en_US/requirejs-config.js. But it’s not working.

And it’s working when I use map on requirejs-config.js to override.

The mixins js file not calling when dataPost.js run.

Any help would be appreciated.
