# Connector Development Kit \(Python\)
|
|
|
|
The Airbyte Python CDK is a framework for rapidly developing production-grade Airbyte connectors. The CDK currently offers helpers specific for creating Airbyte source connectors for:
|
|
|
|
* HTTP APIs \(REST APIs, GraphQL, etc..\)
|
|
* Singer Taps
|
|
* Generic Python sources \(anything not covered by the above\)
|
|
|
|
The CDK provides an improved developer experience by providing basic implementation structure and abstracting away low-level glue boilerplate.
|
|
|
|
This document is a general introduction to the CDK. Readers should have basic familiarity with the [Airbyte Specification](https://docs.airbyte.io/architecture/airbyte-protocol) before proceeding.
|
|
|
|
## Getting Started
|
|
|
|
Generate an empty connector using the code generator. First clone the Airbyte repository then from the repository root run
|
|
|
|
```text
|
|
cd airbyte-integrations/connector-templates/generator
|
|
./generate.sh
|
|
```
|
|
|
|
then follow the interactive prompt. Next, find all `TODO`s in the generated project directory -- they're accompanied by lots of comments explaining what you'll need to do in order to implement your connector. Upon completing all TODOs properly, you should have a functioning connector.
|
|
|
|
Additionally, you can follow [this tutorial](https://docs.airbyte.io/connector-development/tutorials/cdk-tutorial-python-http) for a complete walkthrough of creating an HTTP connector using the Airbyte CDK.
|
|
|
|
### Concepts & Documentation
|
|
|
|
See the [concepts docs](docs/concepts/) for a tour through what the API offers.
|
|
|
|
### Example Connectors

* [Exchangerates API](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-exchange-rates/source_exchange_rates/source.py)
|
|
* [Stripe](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-stripe/source_stripe/source.py)
|
|
* [Slack](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-slack/source_slack/source.py)
|
|
|
|
**Singer connectors**:
|
|
|
|
* [Salesforce](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-salesforce-singer/source_salesforce_singer/source.py)
|
|
* [Github](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-github-singer/source_github_singer/source.py)
|
|
|
|
**Simple Python connectors using the barebones `Source` abstraction**:

|
|
### First time setup
|
|
|
|
We assume `python` points to python >=3.9.
|
|
|
|
Setup a virtual env:
|
|
|
|
```text
|
|
python -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install -e ".[dev]" # [dev] installs development-only dependencies
|
|
```
|
|
|
|
#### Iteration
|
|
|
|
* Iterate on the code locally
|
|
* Run tests via `pytest -s unit_tests`
|
|
* Perform static type checks using `mypy airbyte_cdk`. `MyPy` configuration is in `.mypy.ini`.
|
|
* The `type_check_and_test.sh` script bundles both type checking and testing in one convenient command. Feel free to use it!
|
|
|
|
#### Testing
|
|
|
|
All tests are located in the `unit_tests` directory. Run `pytest --cov=airbyte_cdk unit_tests/` to run them. This also presents a test coverage report.
|
|
|
|
#### Publishing a new version to PyPi
|
|
|
|
1. Bump the package version in `setup.py`
|
|
2. Open a PR
|
|
3. An Airbyte member must comment `/publish-cdk dry-run=true` to publish the package to test.pypi.org or `/publish-cdk dry-run=false` to publish it to the real index of pypi.org.
|
|
|
|
## Coming Soon
|
|
|
|
* Full OAuth 2.0 support \(including refresh token issuing flow via UI or CLI\)
|
|
* Airbyte Java HTTP CDK
|
|
* CDK for Async HTTP endpoints \(request-poll-wait style endpoints\)
|
|
* CDK for other protocols
