It's time to write our first FastAPI API.
0:03
We're going to create a simple application that will actually show us a ton of the
0:09
moving parts of FastAPI. Now,
0:11
because I want to just focus on getting everything set up,
0:14
I'm gonna first have us build a simple little calculator
0:18
API. You'll be able to submit a couple of numbers that will do
0:21
some simple math. The programming will be as basic as it gets.
0:25
But what will not be basic will be all the things around
0:29
FastAPI we're doing: the types being passed in, the validation,
0:32
the required fields, the error reporting,
0:35
all of those types of things.
0:36
We're going to focus on that and then going to come back for a second iteration
0:38
and build a much more interesting and complicated API
0:43
that would be, well, more realistic. But let's start by building a really cool calculator app.
