Loading external project inside ionic page

Ionic Framework ionic-v3
1

Hi!
I am working in a external project, make with Playcanvas framework. It has this structure:
image
And the index.html has this code:

<!doctype html>
<html>
<head>
    <meta name='viewport' content='width=device-width, initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no' />
    <meta charset='utf-8'>
    <link rel="stylesheet" type="text/css" href="styles.css">
    <link rel="manifest" href="manifest.json">
    <style></style>
    <title>Stitched</title>
    <script src="playcanvas-stable.min.js"></script>
    <script>
        ASSET_PREFIX = "";
        SCRIPT_PREFIX = "";
        SCENE_PATH = "539279.json";
        CONTEXT_OPTIONS = {
            'antialias': true,
            'alpha': false,
            'preserveDrawingBuffer': false,
            'preferWebGl2': true
        };
        SCRIPTS = [ 8637973, 8637936, 8638001, 8580837, 8580833, 8580832, 8580836, 8580845, 8580835, 8580834, 8580915, 8591119, 8593254, 8617207, 8622272 ];
        CONFIG_FILENAME = "config.json";
        pc.script.legacy = false;
    </script>
</head>
<body>
    <script src="__start__.js"></script>
    <script src="__loading__.js"></script>
</body>
</html>

I want integrate all the playcanvas project inside a ionic project page, no iframes and no “in app browser”
How can I do?

Thanks!!
