I can fix the mypy issues we currently have so we can add it. Maybe duplicate some of the code that is on asgiref (django/asgiref#221) until its release? What do you think? @euri10 For reference, running mypy without any options: $ mypy uvicorn/

It's a good idea @Kludex one by one or more if that makes more sense |

Ahhh! Ok, perfect. Makes sense. Thank you :) |

* Add changes from PR #992 This commit will bring in changes to uvicorn/config.py added by @Kludex in PR #992, updating for the latest master branch. * Correct SSL type annotations #992 https://docs.python.org/3/library/ssl.html#ssl.SSLContext.load_cert_chain - `certfile` is a required positional argument when running `SSLContext.load_cert_chain`, so annotating as `Optional` (which allows `None`) would not be ideal. Path-like objects are acceptable, so after `from pathlib import Path`, the annotation is `certfile: Union[Path, str]`. - `if self.is_ssl and self.ssl_certfile` will help ensure that the `self.ssl_certfile` required positional argument is present. * Simplify log_config type annotation `Dict[str, Any]` can be simplified to `dict`. * Add type annotation for app #990 #992 app is sometimes a string, as described in uvicorn/main.py. In other cases, especially in the tests, app is an ASGI application callable. This commit will add a type annotation for the app argument to address these use cases. * Simplify if expression in Config().headers * Allow paths to be used for Config(env_file) * Add asyncio Protocol types to class Config kwargs Protocol classes are sometimes used for the app kwarg, such as in tests/test_config.py. * Improve use of Literal type for ASGI interfaces https://mypy.readthedocs.io/en/stable/literal_types.html This commit will retain the use of literals to define ASGI protocol versions, but improve and correct the use of literal types. As described in the mypy docs, `Literal["2.0", "3.0"]` is a simpler way to write `Union[Literal["2.0"], Literal["3.0"]]`. * Add type annotation to Config kwargs in workers.py https://mypy.readthedocs.io/en/stable/type_inference_and_annotations.html This is just one of those times when mypy needs a little help. * Add type annotations to test_config.py PR #978 added logic to convert `reload_dirs` from string to list, as shown in `test_reload_dir_is_set()`, so the annotation on reload_dirs will be updated to accept a string. * Type-annotate constants in uvicorn/config.py Prevents mypy `[has-type]` errors ("Cannot determine type of {object}") * Correct type annotations in uvicorn/importer.py #1046 #1067 The relationship between module imports and calls in uvicorn/config.py was previously unclear. `import_from_string` was annotated as returning a `ModuleType`, but was being used as if it were returning callables. Mypy was raising "module not callable" errors, as reported in #1046. Current use cases of `import_from_string` include: - `uvicorn.Config.HTTP_PROTOCOLS`, `uvicorn.Config.WS_PROTOCOLS`: `Type[asyncio.Protocol]` (these are subclasses of asyncio protocols, so they are annotated with `Type[Class]` as explained in the mypy docs - `uvicorn.Config.LOOP_SETUPS`: `Callable` (each loop is a function) - `uvicorn.Config().loaded_app`: `ASGIApplication` (should be an ASGI application instance, like `Starlette()` or `FastAPI()`) Ideally, the return type of `import_from_string` would reflect these use cases, but the complex typing will be difficult to maintain. For easier maintenance, the return type will be `Any`, and objects returned by `import_from_string` will be annotated directly. * Use os.PathLike for paths in uvicorn/config.py #1067 (comment) Alternative to `pathlib.Path` introduced in Python 3.6. * Use more specific types in test_config.py #1067 (comment) #1067 (comment) https://github.com/encode/starlette/blob/b6f3578bb2cf6c60e3efe110143409b47f368d36/starlette/config.py#L16 https://github.com/python/cpython/blob/3e1c7167d86a2a928cdcb659094aa10bb5550c4c/Lib/os.py#L737 https://docs.pytest.org/en/latest/reference/reference.html#pytest.FixtureRequest - Add custom types for exceptions and start response - Use `MutableMapping` for `os.environ`: matches starlette/config.py. - Use `pytest.FixtureRequest` for fixture requests. The `param` attribute is optional, so mypy requires a check for the attribute before indexing into it (`getattr(request, "param")`). * Install missing YAML type stubs for mypy #1067 Fixes `[import]` error: Library stubs not installed for "yaml" * Add Environ type to test_config.py #1067 (comment) * Add Literal type aliases for web server config #1067 (comment) * Use suggested casing for Literal type aliases #1067 (comment) #1067 (comment) * Restore test_config.py test_app_factory comment #1067 (comment) Incorrectly modified in c436bba. * Simplify event loop setup in config.py #1067 (comment) * Remove old type comment after merging master #1067 (comment) * Assert that certfile is present for SSL context #1067 (comment) https://docs.python.org/3/library/ssl.html#ssl.SSLContext.load_cert_chain `certfile` is a required argument for `SSLContext.load_cert_chain`. As it is currently, `is_ssl` could return `True` without `certfile`. * Restore support for Config(loop='none') #455 e9e59e9 e60ba66 #1067 (comment) * Move WSGI types to uvicorn/_types.py #1067 (comment) * Remove Awaitable from app type annotation #1067 (comment) Co-authored-by: euri10 <euri10@users.noreply.github.com>

Fixes #976
If the user runs programmatically uvicorn he can do a:
uvicorn.run(.....,reload_dirs="/home/maxou/dev/proj")OP suggested we complain about that not being a list, I'd prefer we do it directly for him.
I added a test too
That kind of stuff makes me thing we should mypy the project, but this is another story
