## Overview

`GitHubRepoViewer` provides different behavior based on the path type:

- **For directories**: Returns a list of documents, one for each item (files and subdirectories),
- **For files**: Returns a single document containing the file content.

Each document includes rich metadata such as the path, type, size, and URL.

### Authorization

The component can work without authentication for public repositories, but for private repositories or to avoid rate limiting, you can provide a GitHub personal access token.

You can set the token using the `GITHUB_TOKEN` environment variable, or pass it directly during initialization via the `github_token` parameter.

To create a personal access token, visit [GitHub's token settings page](https://github.com/settings/tokens).

### Installation

Install the GitHub integration with pip:

```shell
pip install github-haystack
```

## Usage

:::info[Repository Placeholder]

To run the following code snippets, you need to replace the `owner/repo` with your own GitHub repository name.

### On its own

Viewing a directory listing:

```python
from haystack_integrations.components.connectors.github import GitHubRepoViewer

viewer = GitHubRepoViewer()
result = viewer.run(
    repo="deepset-ai/haystack",
    path="haystack/components",
    branch="main",
)

print(result)
```

```bash
{'documents': [Document(id=..., content: 'agents', meta: {'path': 'haystack/components/agents', 'type': 'dir', 'size': 0, 'url': 'https://github.com/deepset-ai/haystack/tree/main/haystack/components/agents'}), ...]}
```

Viewing a specific file:

```python
from haystack_integrations.components.connectors.github import GitHubRepoViewer

viewer = GitHubRepoViewer(repo="deepset-ai/haystack", branch="main")
result = viewer.run(path="README.md")

print(result)
```

```bash
{'documents': [Document(id=..., content: '<div align="center">
  <a href="https://haystack.deepset.ai/"><img src="https://raw.githubuserconten...', meta: {'path': 'README.md', 'type': 'file_content', 'size': 11979, 'url': 'https://github.com/deepset-ai/haystack/blob/main/README.md'})]}
```
