We don’t have specific tutorials on creating custom apps with Flask and Vue.js - but you should be able to piece together the process by understanding how to work with Shopify’s APIs in Flask and how to integrate Vue.js for your frontend. For example, concepts such as OAuth for authentication, would apply the same regardless of your tech stack. We don’t currently have a Python Flask API library planned, so the best approach would be that your Vue.js app will make API requests to your Flask backend, which in turn communicates with Shopify’s API endpoints.
