# PyPI publish GitHub Action
This action allows you to upload your [Python distribution package](
https://packaging.python.org/glossary/#term-distribution-package) to
PyPI.


## Usage

To use the action add the following step to your workflow file (e.g.
`.github/workflows/main.yml`)


```yml
- name: Publish a Python distribution to PyPI
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.pypi_password }}
```

A common use case is to upload packages only on a tagged commit, to do so add a
filter to the step:


```yml
  if: github.event_name == 'push' && startsWith(github.event.ref, 'refs/tags')
```

So the full step would look like:


```yml
- name: Publish package
  if: github.event_name == 'push' && startsWith(github.event.ref, 'refs/tags')
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.pypi_password }}
```

The example above uses the new [API token](https://pypi.org/help/#apitoken)
feature of PyPI, which is recommended to restrict the access the action has.

The secret used in `${{ secrets.pypi_password }}` needs to be created on the settings
page of your project on GitHub. See [Creating & using secrets].


## Non-goals

This GitHub Action [has nothing to do with _building package
distributions_]. Users are responsible for preparing dists for upload
by putting them into the `dist/` folder prior to running this Action.


## Advanced release management

For best results, figure out what kind of workflow fits your
project's specific needs.

For example, you could implement a parallel workflow that
pushes every commit to Test PyPI or your own index server,
like `devpi`. For this, you'd need to (1) specify a custom
`repository_url` value and (2) generate a unique version
number for each upload so that they'd not create a conflict.
The latter is possible if you use `setuptools_scm` package but
you could also invent your own solution based on the distance
to the latest tagged commit.

You'll need to create another token for a separate host and then
[save it as a GitHub repo secret][Creating & using secrets].

The action invocation in this case would look like:
```yml
- name: Publish package to Test PyPI
  uses: pypa/gh-action-pypi-publish@master
  with:
    user: __token__
    password: ${{ secrets.test_pypi_password }}
    repository_url: https://test.pypi.org/legacy/
```
