# Full Stack FastAPI Template

Templates, while typically come with a specific setup, are designed to be flexible and customizable. This allows you to modify and adapt them to your project's requirements, making them an excellent starting point. 🏁

You can use this template to get started, as it includes a lot of the initial set up, security, database and some API endpoints already done for you.

 *
 * <h3>Extension</h3>
 *
 * If you want a class like {@code FluentFuture} but with extra methods, we recommend declaring your
 * own subclass of {@link ListenableFuture}, complete with a method like {@link #from} to adapt an
 * existing {@code ListenableFuture}, implemented atop a {@link ForwardingListenableFuture} that
 * forwards to that future and adds the desired methods.

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS

In the [previous chapter about HTTPS](https.md){.internal-link target=_blank} we learned about how HTTPS provides encryption for your API.

  enum class DnsClass(val type: Int) {
    IPV4(TYPE_A),
    IPV6(TYPE_AAAA),
  }

  @ExperimentalOkHttpApi
  companion object {
    const val TYPE_A = 1
    const val TYPE_AAAA = 28

    /**
     * Adapt an AsyncDns implementation to Dns, waiting until onComplete is received
     * and returning results if available.
     */
    fun toDns(vararg asyncDns: AsyncDns): Dns =
      Dns { hostname ->

	expected := false
	if locked != expected {
		t.Errorf("TestDualWriteLockTimedOut(): \nexpected %#v\ngot      %#v", expected, locked)
	}
}

// Test cases below are copied 1 to 1 from sync/rwmutex_test.go (adapted to use LRWMutex)

// Borrowed from rwmutex_test.go
func parallelReader(ctx context.Context, m *LRWMutex, clocked, cunlock, cdone chan bool) {
	if m.GetRLock(ctx, "", "", time.Second) {
		clocked <- true
