Sensor Fusion Web App

An Angular SPA with a Firebase back end. This is a demo project I created which I use to learn or test new technologies. The premise is that the app would be used by hackers and tinkerers to analyze data recorded by their sensors and instruments.

The front end uses the Angular Material library to give a clean material style. Charting is provided by D3.js. Heavy reliance on RxJS allows the front end to update seamlessly when new data is pushed from the Firebase Firestore real-time database. Authentication is provided by Firebase and integrates with a user's Google account for easy sign-up and log in. Front-end state management uses Akita which relies on reactive programming to adapt to changes in state.
