== Step 1. Viewing available Tasks
A _task_ is a basic unit of work that can be done by Gradle as part of the build.

In the `tutorial` directory, enter the command below to list all the available tasks in the project:
[source,text]
----
$ ./gradlew tasks
----

The list includes tasks contributed by the `application` plugin and the plugin it applies:

[source,text]

		// mechanism.
		if level == 31 {
			// Since len(codes) >= 2 the only way that the values
			// can match at all 32 bits is if they are equal, which
			// is invalid. This ensures that we never enter
			// infinite recursion.
			return 0, StructuralError("equal symbols in Huffman tree")
		}

		if len(left) == 0 {
			return buildHuffmanNode(t, right, level+1)
		}

	traceEvGoBlock             // goroutine blocks [timestamp, reason, stack ID]
	traceEvGoUnblock           // goroutine is unblocked [timestamp, goroutine ID, goroutine seq, stack ID]
	traceEvGoSyscallBegin      // syscall enter [timestamp, P seq, stack ID]
	traceEvGoSyscallEnd        // syscall exit [timestamp]
	traceEvGoSyscallEndBlocked // syscall exit and it blocked at some point [timestamp]

Mas nesse caso, a mesma aplicação **FastAPI** irá lidar com a API e a autenticação.

Então, vamos rever de um ponto de vista simplificado:

* O usuário digita o `username` e a `senha` no frontend e aperta `Enter`.
* O frontend (rodando no browser do usuário) manda o `username` e a `senha` para uma URL específica na sua API (declarada com `tokenUrl="token"`).

But in this case, the same **FastAPI** application will handle the API and the authentication.

So, let's review it from that simplified point of view:

* The user types the `username` and `password` in the frontend, and hits `Enter`.
* The frontend (running in the user's browser) sends that `username` and `password` to a specific URL in our API (declared with `tokenUrl="token"`).
