I have been creating APIs with complex requirements for several years (Machine Learning, distributed systems, asynchronous jobs, NoSQL databases, etc), leading several teams of developers.

As part of that, I needed to investigate, test and use many alternatives.

The history of **FastAPI** is in great part the history of its predecessors.

As said in the section [Alternatives](alternatives.md):

    @DisabledOnOs(value = WINDOWS, disabledReason = "need to investigate why it fails on windows")
    void testProjectInheritance() throws Exception {
        File localRepo = getLocalRepositoryPath();

        System.out.println("Local repository is at: " + localRepo.getAbsolutePath());

			pathJoin(diskPath, minioMetaTmpBucket),
			tmpOld,
			osErrToFileErr(err)))
	}

	if err := mkdirAll(pathJoin(diskPath, minioMetaTmpDeletedBucket), 0o777, diskPath); err != nil {
		storageLogIf(GlobalContext, fmt.Errorf("unable to create (%s) %w, drive may be faulty, please investigate",
			pathJoin(diskPath, minioMetaTmpBucket),
			err))
	}

/// info

If you are a very strict "Pythonista" you might dislike the style of the parameter name `tokenUrl` instead of `token_url`.

That's because it is using the same name as in the OpenAPI spec. So that if you need to investigate more about any of these security schemes you can just copy and paste it to find more information about it.

///

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".
