-----
This package provides two Hatch plugins:

- [version source plugin](https://hatch.pypa.io/latest/plugins/version-source/) that reads/writes the package version
  from the `version` field of the Node.js `package.json` file.
- [metadata hook plugin](https://hatch.pypa.io/latest/plugins/metadata-hook/) that reads PEP 621 metadata from the
  Node.js `package.json` file.

## Global dependency

Ensure `hatch-nodejs-version` is defined within the `build-system.requires` field in your `pyproject.toml` file.

```toml
[build-system]
requires = ["hatchling", "hatch-nodejs-version"]
build-backend = "hatchling.build"
```

## Version source

The [version source plugin](https://hatch.pypa.io/latest/plugins/version-source/) name is `nodejs`.

- ***pyproject.toml***

    ```toml
    [tool.hatch.version]
    source = "nodejs"
    ```

- ***hatch.toml***

    ```toml
    [version]
    source = "nodejs"
    ```

### Semver

The semver specification defines the following version sections:

- `major`
- `minor`
- `patch`
- `pre-release`
- `build`

Meanwhile, [PEP 440](https://peps.python.org/pep-0440/#version-scheme) defines:

- `epoch`
- `major`
- `minor`
- `patch`
- `pre-release`
- `post-release`
- `dev-release`

In order to ensure contentful round-trip support, and ensure semantic consistency between Node.js and Python, this plugin only
accepts the common version parts:

- `major`
- `minor`
- `patch`
- `pre-release`
- `dev-release`

e.g. `1.2.3-rc0`.

Note that where normalisation occurs, the round-trip result will differ. This can be avoided by careful choice of the delimeters e.g. `-.`.


### Version source options

| Option        | Type | Default       | Description                                |
|---------------| --- |---------------|--------------------------------------------|
| `path`        | `str` | `package.json` | Relative path to the `package.json` file. |

## Metadata hook

The [metadata hook plugin](https://hatch.pypa.io/dev/plugins/metadata-hook/reference/) name is `nodejs`.

- ***pyproject.toml***

    ```toml
    [tool.hatch.metadata.hooks.nodejs]
    ```

- ***hatch.toml***

    ```toml
    [metadata.hooks.nodejs]
    ```

### Metadata hook options

| Option                        | Type            | Default          | Description                                                                                                                               |

| `path`                        | `str`           | `"package.json"` | Relative path to the `package.json` file.                                                                                                 |
| `fields`                      | `list` of `str` | `None`           | Optional list of `pyproject.toml` fields to take from their counterparts in `package.json`. If missing, take all of the available fields. |
| `contributors-as-maintainers` | `bool`          | `True`           | Whether contributors in `package.json` should be considered maintainers (otherwise, treat them as authors).                               |
| `bugs-label`                  | `str`           | `"Bug Tracker"`  | The key in the URLs table of `pyproject.toml` that is populated by the `bugs` field in `package.json`                                     |
| `homepage-label`              | `str`           | `"Homepage"`     | The key in the URLs table of `pyproject.toml` that is populated by the `homepage` field in `package.json`                                 |
