main.js just create a basic window and load index.html

index.html

<body>
    <div>
        <button type="button" onclick="hello()">Call Hello</button>
    </div>
    <span id="hello"></span>

    <script>
        window.onload = function () {
            try {
                var ref = require('ref');
                // let ffi = require('ffi');
                // console.log('fii.Library result:', ffi);
                // window.lib = ffi.Library('test.dylib', {
                //     hello: ['int', ['pointer']]
                // });
                // console.log('fii.Library result:', window.lib);
            } catch (error) {
                console.error('ffi.Library', error);
            }
        };
        function hello() {
            // let callback = require('ffi').Callback('void', ['int', 'string'], function (size, reply) {
            //     document.getElementById('hello').innerHTML = reply;
            // });
            // window.lib.hello(callback);
        }
    </script>

</body>

npm i works well npm start with the error below
