**You can update dependencies in the Hallmark repository by modifying the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) file and running standard npm commands, though the project currently ships with zero runtime dependencies and requires manual addition of any new libraries.**

The Nutlope/hallmark repository is a lightweight design-skill package that currently maintains a minimal footprint with no runtime dependencies declared in its [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json). While this zero-dependency structure eliminates the routine need for security patches, you may need to update dependencies in Nutlope/hallmark when adding build tools, CSS processors, or testing frameworks. Understanding how to modify the dependency tree ensures you can safely extend the project's capabilities without breaking the static site preview served on port 4173.

## Understanding the Current Dependency Structure

The Hallmark project is architected as a static asset collection with no build step required for basic operation. In the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) file located at the repository root, you will find metadata fields such as `name`, `version`, and `files`, but notably absent are the `dependencies` and `devDependencies` sections. The `scripts` entry contains only a `serve` command that launches a Python HTTP server: `python3 -m http.server --directory site 4173`.

Because the codebase currently consists only of HTML, CSS, and JavaScript files in the `site/` directory, there are no packages to update out of the box. Any dependency management workflow begins with adding a dependency declaration to the previously empty [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json).

## How to Add New Dependencies to Hallmark

When extending the project with build tools or utility libraries, you must first create the dependency section in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json).

### Installing Development Dependencies

For tools like linters, formatters, or bundlers that are not required in production, use the `--save-dev` flag:

```bash
npm install --save-dev eslint@latest

```

This command automatically creates a `devDependencies` object in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) and locks the version in [`package-lock.json`](https://github.com/Nutlope/hallmark/blob/main/package-lock.json).

### Installing Production Dependencies

If you add runtime libraries that the application requires to function, use:

```bash
npm install --save luxon@latest

```

This populates the `dependencies` section. After installation, verify the change by checking that [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) now contains the new entry:

```json
{
  "name": "hallmark",
  "version": "1.1.0",
  "type": "module",
  "files": ["skills"],
  "scripts": {
    "serve": "python3 -m http.server --directory site 4173"
  },
  "devDependencies": {
    "eslint": "^8.57.0"
  }
}

```

## How to Update Existing Dependencies

Once you have dependencies declared, use the npm CLI to check for and apply updates.

### Checking for Outdated Packages

Run the outdated command to see which packages have newer versions available:

```bash
npm outdated

```

This compares your installed versions against the registry and lists any semver-compatible updates.

### Updating Specific Packages

To update a single package to its latest version, reinstall with the `@latest` tag:

```bash
npm install --save-dev postcss@latest

```

### Updating All Dependencies at Once

For bulk updates that respect semantic versioning constraints defined in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json), run:

```bash
npm update
npm install

```

The `npm update` command pulls the latest semver-compatible versions, while `npm install` ensures the lockfile is refreshed to reflect the exact versions installed.

## Verifying Updates with the Development Server

After modifying dependencies, always verify that the static site still renders correctly. The Hallmark repository includes a serve script that launches a Python-based HTTP server:

```bash
npm run serve

```

This executes `python3 -m http.server --directory site 4173`, making the site available at `http://localhost:4173`. Open this URL in your browser and confirm that all interactive elements in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js) function as expected before committing changes.

## Key Files Affected by Dependency Changes

When you update dependencies in Nutlope/hallmark, three files typically change:

- **[`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json)**: Contains the version specifications for your dependencies and devDependencies.
- **[`package-lock.json`](https://github.com/Nutlope/hallmark/blob/main/package-lock.json)**: Automatically generated file that locks exact versions for reproducible installs.
- **[`site/index.html`](https://github.com/Nutlope/hallmark/blob/main/site/index.html)**: The main entry point you should manually test after adding build tools that might affect the output.

According to the Hallmark source code, the [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) file documents the skill itself but does not govern dependency management; all package-related configuration resides solely in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json).

## Summary

- The Hallmark repository currently ships with **zero dependencies** in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json), requiring you to manually add any needed libraries.
- Use **`npm install --save-dev`** for build tools and **`npm install --save`** for runtime libraries.
- Check for available updates with **`npm outdated`** and apply them with **`npm install <package>@latest`** or **`npm update`**.
- Always run **`npm run serve`** to launch the Python HTTP server on port 4173 and verify the site at `http://localhost:4173` after making changes.
- Commit both **[`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json)** and **[`package-lock.json`](https://github.com/Nutlope/hallmark/blob/main/package-lock.json)** to ensure reproducible builds across environments.

## Frequently Asked Questions

### Does Hallmark have any dependencies to update out of the box?

No. According to the Nutlope/hallmark source code, the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) file contains no `dependencies` or `devDependencies` sections. The project consists of static assets served via Python's HTTP server, so there are no packages to update until you manually add build tools or libraries.

### What package manager should I use for updating dependencies?

The repository uses npm by default, as evidenced by the [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) structure. You can use npm commands like `npm install`, `npm outdated`, and `npm update`. While pnpm or yarn would work if you prefer them, the documented serve script and file structure align with standard npm workflows.

### How do I verify that dependency updates haven't broken the site?

After running `npm install` to update packages, execute `npm run serve` to launch the Python HTTP server on port 4173. Navigate to `http://localhost:4173` in your browser and verify that [`site/index.html`](https://github.com/Nutlope/hallmark/blob/main/site/index.html) renders correctly and that the interactive features in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js) function as expected before committing your changes.

### Can I add build tools like Vite or esbuild to Hallmark?

Yes. Since the project currently uses a simple Python HTTP server defined in the `serve` script, you can safely add Node.js-based build tools. Install them as devDependencies with `npm install --save-dev vite@latest`, then modify the `scripts` section in [`package.json`](https://github.com/Nutlope/hallmark/blob/main/package.json) to include build commands alongside or replacing the Python server command.
