Firebase is an application platform for web, Android and iOS.
We know web, not Android or iOS, and we're teaching what we know; therefore, this course will be entirely focused on Firebase for web.
So why should you use Firebase as your web app platform?
You want to use Firebase because it gives you a huge suite of services that you don't have to write.
You could duplicate Firebase's services yourself, but why spend the time and money? And good luck coming in under Firebase's price point. It's not like Firebase is some extravagantly expensive service. The billing structure is entirely reasonable and one of the least expensive options... especially when you consider developer time saved.
And all of Firebase's services are fully integrated. They talk to each other out of the box and use cohesive APIs. So you won't waste time architecting. You won't waste time integrating micro-services. You'll cough up a few pennies for Google's compute and storage resources, and you'll spend your valuable time writing your own application logic.
In short, Firebase saves you time. We've seen greater-than 50% reductions in developer workload for even simple projects. Your codebase stays smaller. Your bugs stay fewer. And you can ship more features with the same team.
And by saving you time, Firebase saves you money. Lots of money.
Startups need to write minimum-viable products. They need to prototype. They don't need to focus on scaling in the early days.
Firebase lets you bootstrap your initial prototype on Google-scale infrastructure. This is a massive selling point.
Consider the typical early-product lifecycle.
You build a prototype. Customers like it, so you expand it to a minimum-viable product and sell it to the marketplace.
The marketplace likes it, so now you have to manage a growing user-base AND ship new features.
A typical startup architecture would include servers and databases, all of which you'd need to provision and scale to keep up. This leaves your team strapped for time, because they're still building new features.
Firebase architecture abstracts all of that away. Your code is "serverless", meaning that you don't manage servers yourself. You write code and Firebase puts it on Google's servers and scales it up and down as needed.
You can service millions of customers on the same architecture and infrastructure that you used for your prototype.
