The following document covers how to develop the InfluxDB client library locally. Including how to run tests and build the docs.


# from your forked repo, create and activate a virtualenv
python -m virtualenv venv
. venv/bin/activate
# install the library as editable with all dependencies
make install
# make edits
# run lint and tests
make lint test

Getting Started With Development

  1. Install Python

    Most distributions include Python by default, so before going too far, try running python --version to see if it already exists. You may also have to specify python3 --version, for example, on Ubuntu.

  2. Fork and clone the repo

    The rest of this assumes you have cloned your fork of the upstream client library and are in the same directory of the forked repo.

  3. Set up a virtual environment.

    Python virtual environments let you install specific versioned dependencies in a contained manner. This way, you do not pollute or have conflicts on your system with different versions.

    python -m virtualenv venv
    . venv/bin/activate

    Having a shell prompt change via starship or something similar is nice as it will let you know when and which virtual environment in you are in.

    To exit the virtual environment, run deactivate.

  4. Install the client library

    To install the local version of the client library run:

    make install

    This will install the library as editable with all dependencies. This includes all dependencies that are used for all possible features as well as testing requirements.

  5. Make changes and test

    At this point, a user can make the required changes necessary and run any tests or scripts they have.

    Before putting up a PR, the user should attempt to run the lint and tests locally. Lint will ensure the formatting of the code, while tests will run integration tests against an InfluxDB instance. For details on that set up see the next section.

    make lint test


The library uses flake8 to do linting and can be run with:

make lint


The built-in tests assume that there is a running instance of InfluxDB 2.x up and running. This can be accomplished by running the scripts/ script. It will launch an InfluxDB 2.x instance with Docker and make it available locally on port 8086.

Once InfluxDB is available, run all the tests with:

make test

Code Coverage

After running the tests, an HTML report of the tests is available in the htmlcov directory. Users can open html/index.html file in a browser and see a full report for code coverage across the whole project. Clicking on a specific file will show a line-by-line report of what lines were or were not covered.

Documentation Building

The docs are built using Sphinx. To build all the docs run:

make docs

This will build and produce a sample version of the web docs at docs/_build/html/index.html. From there the user can view the entire site and ensure changes are rendered correctly.
