How to install

VSCode extension

Add AWS Boto3 extension to your VSCode and run AWS boto3: Quick Start command.

From PyPI with pip

Install botocore-stubs to add type annotations for botocore package. Install boto3-stubs to add type annotations for boto3 package.

# install type annotations only for botocore
python -m pip install botocore-stubs

# install type annotations only for boto3 and botocore
python -m pip install botocore-stubs boto3-stubs

# install `boto3` type annotations
# for ec2, s3, rds, lambda, sqs, dynamo and cloudformation
# Consumes ~7 MB of space
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]'

# or install annotations for services you use
python -m pip install 'boto3-stubs[acm,apigateway]'

From conda-forge

Installing boto3-stubs from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge
conda config --set channel_priority strict

Once the conda-forge channel has been enabled, boto3-stubs and boto3-stubs-essential can be installed with:

conda install boto3-stubs boto3-stubs-essential

It is possible to list all of the versions of boto3-stubs available on your platform with:

conda search boto3-stubs --channel conda-forge

How to uninstall

# uninstall boto3-stubs
python -m pip uninstall -y boto3-stubs botocore-stubs

# uninstall submodules
python -m pip freeze | grep mypy-boto3 | xargs python -m pip uninstall -y

Usage

VSCode

• Install Python extension
• Install Pylance extension
• Set Pylance as your Python Language Server
• Install boto3-stubs with services you use in your environment: python -m pip install 'boto3-stubs[s3,ec2]'

Both type checking and code completion should work for installed boto3 services. No explicit type annotations required, write your boto3 code as usual.

PyCharm

• Install boto3-stubs-lite with services you use in your environment:

python -m pip install 'boto3-stubs-lite[s3,ec2]'

Both type checking and code completion should work for installed services. Explicit type annotations are required. Use boto3-stubs package instead for implicit type discovery.

Emacs

• Install boto3-stubs with services you use in your environment: python -m pip install 'boto3-stubs[s3,ec2]'
• Install use-package, lsp, company and flycheck packages
• Install lsp-pyright package

(use-package lsp-pyright
  :ensure t
  :hook (python-mode . (lambda ()
                          (require 'lsp-pyright)
                          (lsp)))  ; or lsp-deferred
  :init (when (executable-find "python3")
          (setq lsp-pyright-python-executable-cmd "python3"))
  )

• Make sure emacs uses the environment where you have installed boto3-stubs

Sublime Text

• Install boto3-stubs with services you use in your environment: python -m pip install 'boto3-stubs[s3,ec2]'
• Install LSP-pyright package
• Make sure emacs uses the environment where you have installed boto3-stubs

Other IDEs

Not tested, but as long as your IDE supports mypy or pyright, everything should work.

mypy

• Install mypy: python -m pip install mypy
• Install boto3-stubs with services you use in your environment: python -m pip install 'boto3-stubs[s3,ec2]'
• Run mypy as usual

Type checking should work for installed boto3 services. No explicit type annotations required, write your boto3 code as usual.

pyright

• Install pyright: yarn global add pyright
• Install boto3-stubs with services you use in your environment: python -m pip install 'boto3-stubs[s3,ec2]'
• Optionally, you can install boto3-stubs to typings folder.

Type checking should work for installed boto3 services. No explicit type annotations required, write your boto3 code as usual.

How it works

Fully automated mypy-boto3-builder carefully generates type annotations for each service, patiently waiting for boto3 updates. It delivers a drop-in type annotations for you and makes sure that:

• All available boto3 services are covered.
• Each public class and method of every boto3 service gets valid type annotations extracted from the documentation (blame botocore docs if types are incorrect).
• Type annotations include up-to-date documentation.
• Link to documentation is provided for every method.
• Code is processed by black and isort for readability.
