Tooling to manage the `pyodide-lock.json` file.

Note: the API of this package is still being iterated on and may change completely

before the 0.1 release.

The `pyodide-lock` file is used to lock the versions of the packages that are

used in a given Pyodide application. Packages included in `pyodide-lock.json`

will be auto-loaded at import time, when using `pyodide.runPythonAsync` or

running in JupyterLite or PyScript, and do not need to be explicitly installed

with micropip.

## Installation

```bash

pip install pyodide-lock

```

## Python API

To parsing and write the `pyodide-lock.json` (formerly `repodata.json`) file:

```py

from pyodide_lock import PyodideLockSpec

lock_spec = PyodideLockSpec.from_json("pyodide-lock.json")

# Make some changes

lock_spec.to_json("pyodide-lock.json")

```
