How manage time consuming API Calls in NodeJS

Question

I am using an API from TinyPng.com which helps in compressing images.

When a user uploads images, I make an API call to TinyPng.com with the URL of the image that I want to compress, it provides a response with a link of the compressed file. Based on image size it could take about a few seconds to get a response.

How can I handle such time consuming processes in NodeJS ?
