Docpress ⚡

This project aims to automate the construction of documentation website based on a Github username and optionally a list of repositories.

Explanation

Docpress automates the process of downloading documentation files from specified GitHub repositories. Here's how it works:

1. Repository Documentation Retrieval:

   • The program checks if a docs/ folder is present at the root level of each specified repository.
   • If the docs/ folder exists, the entire folder will be downloaded, including all its contents.
   • If the docs/ folder is not found, only the README.md file will be downloaded.

2. Static Website Generation:

   • After retrieving the documentation files, Docpress generates a static website using VitePress. This framework allows for the creation of fast and customizable documentation sites.

For optimal use of Docpress, please check the rules section to understand the conventions and guidelines that will ensure that everything works correctly. By following these rules, you can maximize the effectiveness of the documentation process.

Quickstart

1. Generate website using the Docpress docker image.

   docker run --name docpress --rm -v $(pwd)/docpress:/app/docpress:rw \
     ghcr.io/this-is-tobi/docpress -u <github_username>

   The dist folder is available at ./docpress/.vitepress/dist, ready to be served by a web server like Nginx, Apache, etc...

2. Start an Nginx docker image using the generated static folder.

   docker run --name my-docs --rm -v ./docpress/.vitepress/dist:/usr/share/nginx/html:ro -p 8080:80 \
     docker.io/nginx

3. Access the website at the following address : http://localhost:8080.

Rules

To ensure that the program functions correctly, please follow these conventions:

1. Documentation folder structure:

   • The script will only parse the docs/ folder located at the root level of the repository. This folder is used to import advanced documentation features, such as multi-page documentation, embedded images, and files.

2. File naming and sorting:

   • If a docs/ folder is present, all files within it will be sorted and renamed by removing any prefix numbers. This ensures that files appear cleanly in the generated website. For example, docs/01-get-started.md will be renamed to get-started.md.

3. Handling the root readme file:

   • The README.md file located at the root of the repository will only be imported if there is no ./docs/01-readme.md file present. This allows you to differentiate between the general README and the advanced documentation introduction page.
   • For instance, you might use the README file for a table of contents that is not relevant in the context of the documentation website.

4. Link management:

   • Any inline link in the ./README.md file that does not point to ./docs/** will be replaced with the corresponding GitHub link.
   • Similarly, any inline link in the ./docs/*.md files that does not reference ./docs/** will also be replaced with the appropriate GitHub link.

5. Project descriptions:

   • The project description displayed on the home page of the generated website is extracted from the GitHub repository's description.

By adhering to these rules, you can ensure that your documentation is processed correctly and that it aligns with the intended structure and functionality of the generated site.

Usage methods

Docpress is available through both npm and Docker, so you can choose the installation method that best suits your environment.

Using npm (or other package managers)

If you prefer Node.js package managers like npm, pnpm, or bun, you can easily install and run Docpress without additional setup.

To run Docpress using npm:

npx @tobi-or-not/docpress -u <github_username>

[!TIP] If you’re using a package manager like pnpm or bun, simply replace npx with the corresponding command (pnpx or bunx) to execute Docpress.

Using Docker

Docpress also provides a Docker image, which is especially useful if you want to avoid installing dependencies directly on your system or if you’re working in a containerized environment. Using Docker ensures a consistent runtime environment.

To run Docpress with Docker:

docker run --rm -v $(pwd)/docpress:/app/docpress:rw ghcr.io/this-is-tobi/docpress -u <github_username>

In this command:

• --rm removes the container after it stops, keeping your environment clean.
• -v $(pwd)/docpress:/app/docpress:rw mounts the docpress directory in your current path to the container’s /app/docpress folder, allowing Docpress to store generated files locally.

Ensure Docker is installed and running on your system before using this method.

Both methods provide the same functionality, so you can choose the one that fits your setup or use case.

Filter repositories

The -r or --repos-filter option allows you to specify which repositories to include or exclude when generating documentation. This option accepts a comma-separated list of repository names and can include exclusions by prefixing a repository name with !.

• Including specific repositories: To generate documentation for specific repositories, provide their names separated by commas. For example, -r 'repo1,repo2' will retrieve documentation only for repo1 and repo2.
• Excluding repositories: To exclude certain repositories, prefix their names with !. For instance, -r '!repo1,!repo2' will retrieve all public repositories except repo1 and repo2.

Only public, non-fork repositories are fetched.

Docpress configuration

Docpress can be configured with an external configuration file specified by the -C or --config option. This file, which should be in JSON or YAML format, allows you to set Docpress parameters to automate and customize the documentation fetching and generation process. Key options that can be configured include:

• username: Git provider username (usually GitHub) to fetch repositories (equivalent to the -u CLI option).
• reposFilter: List of repositories to include or exclude (equivalent to the -r CLI option).
• branch: Default branch from which documentation will be fetched.
• extraHeaderPages: Additional pages to include in the website header (equivalent to -p).
• extraPublicContent: Additional content for the Vitepress public folder (equivalent to -c).
• extraTheme: Files or folders to customize the Vitepress theme (equivalent to -t).

Example JSON configuration:

{
  "username": "my-github-username",
  "reposFilter": ["!repo1", "!repo2"],
  "branch": "main",
  "extraHeaderPages": ["header1.md", "header2.md"],
  "extraPublicContent": ["favicon.ico", "logo.png"],
  "extraTheme": ["custom-theme.css"]
}

Vitepress configuration

Vitepress configuration can be customized via a vitepress.config.js file, specified with the -v or --vitepress-config option. This file lets you adjust Vitepress options like the site title, navigation structure, footer, and plugins.

Key configurable options include:

• title: The title of the generated site.
• description: A description of the site (used for SEO).
• themeConfig: The theme configuration, including navigation and header links.
• markdown: Options to customize Markdown rendering.

Basic Vitepress configuration example:

{
  "title": "My Project Documentation",
  "description": "A site generated by Docpress",
  "themeConfig": {
    "socialLinks": [
      { "icon": "github", "link": "https://github.com/this-is-tobi" }
    ],
    "outline": [2, 4]
  }
}

Vitepress theme

Docpress allows you to customize the Vitepress theme by adding files or directories specified with the -t or --extra-theme option. This flexibility enables you to adjust the look and feel of your documentation site by adding custom CSS, modifying components, or even creating an entirely custom theme.

You can approach theme customization in two main ways:

1. Extending the Default Theme: Vitepress offers options to extend its built-in default theme, which includes configuration for the layout, sidebar, and header. Extending the default theme is a good choice if you want to make minor tweaks to colors, fonts, or layout without changing the overall structure. To do this, you can:

   • Add custom CSS or SCSS files for style adjustments.
   • Override default theme components to change the behavior of certain sections (like headers or footers).
   • Introduce new Vue components if needed.

   For more details on extending the default theme, visit the Vitepress guide on extending the default theme.

2. Creating a Custom Theme: If your project requires a unique design or a complete overhaul of the site layout, you can create a fully custom theme. Vitepress allows you to replace its default theme entirely by creating a custom theme directory structure. With this approach, you gain full control over every part of the site, from page structure to individual components.

   To implement a custom theme:

   • Create a theme/index.js file where you export custom components.
   • Organize components like headers, footers, and layout in the theme directory.
   • Add global styles to theme/style.css or other preferred CSS files.

   For a comprehensive guide on creating a custom theme, refer to the Vitepress documentation on using a custom theme.

For either method, keep in mind that customizations should be tested across different pages to ensure they integrate smoothly with your content.

With these approaches, you can create a distinct look and feel for your documentation site while keeping it aligned with your project’s branding and user experience requirements.

Extra header pages

With the -p or --extra-header-pages option, you can add additional pages to the Vitepress website header, such as privacy policies, advanced user guides, or links to external resources.

This option accepts a comma-separated list of Markdown files or directories containing Markdown files. These pages will be included as-is in the final website and automatically added to the navigation bar at the top of each page on the generated site.

All specified extra-header-pages must be in Markdown format and can include any Vitepress-compatible content, such as links, images, and other documentation elements.

Extra public content

The -c or --extra-public-content option allows you to include additional static assets in the Vitepress public folder. This is useful for adding content that needs to be accessible across all pages of the documentation, such as custom icons, logos, or other assets.

These files or directories will be copied directly into the public folder and will be available as static resources on the final website.

Common use cases for extra-public-content include:

• Adding branding assets: For example, including a custom favicon (favicon.ico) or logo (logo.png) that will display on every page.
• Providing downloadable files: Such as PDF guides, policy documents, or downloadable images that users may need quick access to.
• Supplementing media files: Including additional images, icons, or background files that you may want to reference across different parts of your documentation.

This option accepts a comma-separated list of file or directory paths.

Ensure that any files you add are optimized for the web, as large or uncompressed files may impact site performance.

All files and directories specified with extra-public-content are directly accessible at the root of the final site, making it easy to link to them within your Markdown files (e.g., using /logo.png in an img tag).

GitHub Token Option

When using the Docpress tool to fetch data from GitHub, you have the option to provide a personal access token using the -T flag. This token is important as it allows you to authenticate your requests, which can help increase your request limits on the GitHub API.

Utilizing a personal access token not only helps you avoid rate limiting issues but also enhances the reliability of data retrieval for your documentation projects.

For further details on how authentication affects rate limits and other considerations, please refer to the official GitHub documentation on Rate limits for the REST API.
