Handling Carousels

  type: 'carousel',
  items: [

Dealing with Instagram CORS restrictions

You can download above images/videos/thumbnails using curl or any other similar utility. But if you are using this script on a website then you have to download it on your server and then return the response to user. To avoid this downloading issue, create a generic forwarding route on your server that will stream data from Instagram to your user

// Generic forwardning route
app.get('/api/getFile', async (req, res) => getFile(req, res));

// Handler for above route
const getFile = (req, res) => {
  const { url } = req.query;
  https.get(url, (stream) => {
    stream.pipe(response);
    stream.on('end', () => {
      response.end();
    })
  });
};

So to display thumbnails or images from Instragram, your img tag will be something like below.

<img src="https://yourwebsite.com/api/getFile?url={Link for Instagram image or audio}">
