Used axios

I’m designing an analytics platform as a personal project to work also on frontend and backend development. 
Stack:
 * Vue.JS for frontend 
* Flask based APIs for handling frontend requests 
* Dask for computation 
* Model deployment 
* A small visualisation section based on ChartJS

Implementating access tokens and refresh tokens on the frontend for the first time. It was hard but now it is making a lot of sense. I saved my tokens in local storage and not sure if that is the right to store them?
