What is/does firebase?

• Build scalable applications in the cloud.

• Realtime database: Seamless synchronization between data collection and Frontend

  The main benefit of the realtime database is that your data is synchronized across all of your clients. In practice, this means that we have to deviate a bit from the initial conceptional model of our React database as a simple JSON. While setting a property is similar, you don't simply get a value with the property. Instead, you subscribe to a channel for changes to that property. With that in mind, you design a Firebase client differently than you would with a traditional REST API.
