Hosting a Forge Autodesk viewer on Github - github

Question

I've an issue with the Forge viewer I'm developping : Im' trying to host it using Github-page, but it doesn't seem to work correctly.
The issue is on the File tree : when I load the viewer page from the Github pages, the file tree seems stuck on "Loading...". However, it correctly loads when I load the page from localhost.
The code of the File tree :
$(document).ready(function () {
prepareAppBucketTree();
$('#refreshBuckets').click(function () {
$('#appBuckets').jstree(true).refresh();
});
$('#createNewBucket').click(function () {
createNewBucket();
});
$('#createBucketModal').on('shown.bs.modal', function () {
$("#newBucketKey").focus();
})
$('#hiddenUploadField').change(function () {
var node = $('#appBuckets').jstree(true).get_selected(true)[0];
var _this = this;
if (_this.files.length == 0) return;
var file = _this.files[0];
switch (node.type) {
case 'bucket':
var formData = new FormData();
formData.append('fileToUpload', file);
formData.append('bucketKey', node.id);
$.ajax({
url: '/api/forge/oss/objects',
data: formData,
processData: false,
contentType: false,
type: 'POST',
success: function (data) {
$('#appBuckets').jstree(true).refresh_node(node);
_this.value = '';
}
});
break;
}
});
});
function createNewBucket() {
var bucketKey = $('#newBucketKey').val();
var policyKey = $('#newBucketPolicyKey').val();
console.log(bucketKey)
jQuery.post({
url: '/api/forge/oss/buckets',
contentType: 'application/json',
data: JSON.stringify({ 'bucketKey': bucketKey, 'policyKey': policyKey }),
success: function (res) {
$('#appBuckets').jstree(true).refresh();
$('#createBucketModal').modal('toggle');
},
error: function (err) {
if (err.status == 409)
alert('Bucket already exists - 409: Duplicated')
console.log(err);
}
});
}

Please note that Github Pages are used for serving static pages without any special server-side logic. Your Forge application requires a server to talk to as well, for example, to obtain a list of buckets for the tree view (by making a request to /api/forge/oss/buckets).
You could potentially host your application's server-side logic on something like Heroku, and then have your static HTML/CSS/JavaScript page on Github talk to that server (for example, https://my-forge-app.herokuapp.com/api/forge/oss/buckets). Just be careful about CORS.
