Using built libraries

boto3

Check boto3-stubs project for installation and usage instructions.

If you use VSCode, add AWS Boto3 extension to your VSCode and run AWS boto3: Quick Start command.

If not, just install boto3-stubs with pip:

python -m pip install 'boto3-stubs[essential]'

# Lite version does not provide session.client/resource overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'boto3-stubs-lite[essential]'

# do not forget to install mypy or pyright

That's it! You should already have code completion and type checking in your IDE.

aiobotocore

Check types-aiobotocore project for installation and usage instructions.

Or just install types-aiobotocore with pip:

python -m pip install 'types-aiobotocore[essential]'

# Lite version does not provide session.create_client overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'types-aiobotocore-lite[essential]'

# do not forget to install mypy or pyright

Ready to go! Enjoy code completion and type checking in your aiobotocore project.

aioboto3

Check types-aioboto3 project for installation and usage instructions.

Or just install types-aioboto3 with pip:

python -m pip install 'types-aioboto3[essential]'

# Lite version does not provide session.client/resource overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'types-aioboto3-lite[essential]'

# do not forget to install mypy or pyright

Whoa! All aioboto3 methods and attributes are now type-annotated and even code completion works.

How to build type annotations

Locally

# Install preferred version of `boto3`
python -m pip install boto3==1.16.25 botocore==1.19.25

# Install `mypy-boto3-builder`
python -m pip install mypy-boto3-builder

# Build all packages in mypy_boto3_output directory
python -m mypy_boto3_builder mypy_boto3_output

# Or specify required services explicitly
python -m mypy_boto3_builder mypy_boto3_output -s ec2 s3

# Install custom `boto3-stubs` packages
cd mypy_boto3_output
python -m pip install -e ./mypy_boto3_ec2_package
python -m pip install -e ./mypy_boto3_s3_package
python -m pip install -e ./boto3_stubs_package

With Docker image

  • Install Docker
  • Pull latest mypy_boto3_builder version and tag it
docker pull docker.pkg.github.com/youtype/mypy_boto3_builder/mypy_boto3_builder_stable:latest
docker tag docker.pkg.github.com/youtype/mypy_boto3_builder/mypy_boto3_builder_stable:latest mypy_boto3_builder
  • Generate stubs in output directory
mkdir output

# generate stubs for all services
docker run -v `pwd`/output:/output -ti mypy_boto3_builder_stable

# generate stubs for s3 service
docker run -v `pwd`/output:/output -ti mypy_boto3_builder_stable -s s3

# generate stubs for a specific boto3 version
docker run -e BOTO3_VERSION=1.16.25 BOTOCORE_VERSION=1.19.25 -v `pwd`/output:/output -ti mypy_boto3_builder_stable
  • Install packages from output directory as described above

Development

  • Install Python 3.10+, ideally with pyenv
  • Install poetry: pip install poetry
  • Install dependencies: poetry install
  • Use scripts for repo to check if everything works: ./scripts/build.sh
  • Run manual pre-commit: ./scripts/before_commit.sh

Versioning

mypy_boto3_builder version is not related to boto3 version and follows PEP 440.
