Rainbow tracker v3.0
This update consists of two major changes.
-
Since a new REST API backend was developed, the frontend had to be adapted too. Hence, aspects like authentication and data fetching had to be completely re-written, now that there is no convenient Firebase SDK to be used. All requests to the backend are made using the inbuilt browser Fetch API. Thanks to the new backend implementation, much of the seemingly unnecessary frontend code could be removed. Mostly, the removed code is related to data manipulation in order to save data to Firebase or display data when fetched from Firebase.

Analytics page has seen some improvements. Although it is still a work in progress, it has been a breeze implementing analytics thanks to relational data storing with Postgres. SQL has allowed for a much easier time getting analytical information from the data.
