The author of boto3-stubs must be stalking me ;) This update was posted there 10 hours later:
https://github.com/vemel/mypy_boto3_builder/issues/4#issuecomment-1028776360
So, I am working on types-aiobotocore
. They can be used for aioboto3
as well, smth like:
import aioboto3
from types_aiobotocore_s3.client import S3Client
from types_aiobotocore_s3.service_resource import S3ServiceResource
session = aioboto3.Session()
async with session.client("s3") as s3_client:
s3_client: S3Client # now s3_client should have auto-complete and type checking
async with session.resource("s3") as s3_resource:
s3_resource: S3ServiceResource # resource as well
Please let me know if you are interested. I can create stubs for aioboto3
, but for now, it is out of my scope.
Yes, this sounds absolutely great. Thank you.
Once I get approval, I am going to publish all the packages. Everything works great already, I just need to add integration tests and setup automated builds (not sure if we really need them, as aiobotocore
releases are quite rare)
I did not yet create documentation specifically for aioboto3
but I described how to use it in the comment above. Feel free to try: https://pypi.org/project/types-aiobotocore/
Hey, feel free :)
Let me know when you've got something in pypi and i'll add something to the readme
Hello! I already have types-aiobotocore on PyPI. I can provide a short example how to use it with aioboto3
types-aiobotocore
is really awesome, definitely has saved me some bugs!
One usability issue - I am using with strict MyPy and unfortunately the import aioboto3
fails strict checking:
Skipping analyzing "aioboto3": module is installed,
but missing library stubs or py.typed marker [import]
import aioboto3
^
app/docs/s3.py:7: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
The auto-complete and type checking workaround from above do work well for autocompletion but they also require a type: ignore[no-redef]
for strict mypy to pass:
async with self.boto_session.client("s3") as s3:
s3: S3Client # type: ignore[no-redef]
Ah ha! I fixed my ignore [no-redef]
part! This has the added bonus that mypy type hints the result of the context manager:
async with self.boto_session.client("s3") as s3: # type: S3Client
s3.upload_fileobj(...)
I still have the issue with the aioboto3
import error but this works around the issue with redefinition and also being able to type hint the return of the context manager!
@vemel what do you think?
@phillipuniverse This one fix the issue: https://github.com/youtype/mypy_boto3_builder/issues/153#issuecomment-1184967053
Are there plans to add type system?
While boto3 does not have type annotations, there is a package called boto3-stubs which provides type information making it more enjoyable to program in IDE.
Any plans for aioboto3, to include type annotations?
