# Templates { #templates }

You can use any template engine you want with **FastAPI**.

A common choice is Jinja2, the same one used by Flask and other tools.

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }

We'll explain everything via an example. Let's say you make some changes on your branch `myTestBranch`
(we highly recommend to name this branch without prefix and hyphen (`-`) because it's used to generate build type ID) and want to
test these changes without affecting `master`/`release` pipeline. Here are the instructions.

  }

  /**
   * Marks the given step final, waits for it to be finished, and returns the value.
   *
   * @throws ExecutionException if the step failed
   * @throws CancellationException if the step was cancelled
   */
  abstract <T> T getFinalValue(ClosingFuture<T> closingFuture) throws ExecutionException;

  /** Marks the given step final, cancels it, and waits for the cancellation to happen. */

				// invoke the PutObjectPart HTTP handler.
				apiRouter.ServeHTTP(rec, req)

				// validate the error response.
				want := getAPIError(test.expectedAPIError)
				if test.expectedAPIError == -1 {
					want.HTTPStatusCode = 200
					want.Code = "<no error>"
					want.Description = "<no error>"
				}
				if rec.Code != http.StatusOK {
					var errBytes []byte
					// read the response body.

...But here I want to show you the community.

**FastAPI** receives a lot of support from the community. And I want to highlight their contributions.
