**TLDR: The GPT-Image2 style library data is stored in [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) within the freestylefly/awesome-gpt-image-2 repository, serving as the single source of truth for all categories, styles, scenes, and prompt templates.**

The freestylefly/awesome-gpt-image-2 project organizes its entire style library as a structured JSON document rather than scattering definitions across multiple files. This centralized approach simplifies maintenance and allows the React frontend to dynamically render prompt suggestions without hardcoding content.

## File Location and Data Structure

### The Master JSON File

All style definitions reside in a single version-controlled file at the repository root:

- **File path:** [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json)
- **Direct link:** [https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json)

According to the source code, this JSON contains six primary keys that define the entire user experience. The `categories` array stores classification objects with titles and cover images, while the `styles` and `scenes` arrays contain keyword-rich objects used for prompt generation. The `templates` array holds the most complex structures, linking specific categories, styles, and scenes to detailed prompt guidance and example cases.

### Schema Components

The JSON structure follows a strict schema to ensure consistency across the application:

| Section | Purpose |
|---------|---------|
| `version` | Library version number for cache busting |
| `repository` | Self-reference to the project source |
| `templateDocument` | Path to human-readable template docs ([`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md)) |
| `tagLabels` | Bilingual mapping (English/Chinese) for UI display |
| `categories` | Visual organization buckets with metadata |
| `styles` | Artistic style definitions with keywords |
| `scenes` | Environmental context keywords |
| `templates` | Complete prompt templates with guidance and pitfalls |

## How the Frontend Accesses the Library

The React application consumes this JSON through standard HTTP requests or static imports. The entry point [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) initializes the application by loading this data to populate dropdowns, filter chips, and template galleries.

### Fetching the Style Library

Below is the pattern used to load the library asynchronously in React components:

```javascript
import { useEffect, useState } from 'react';

function useStyleLibrary() {
  const [library, setLibrary] = useState(null);

  useEffect(() => {
    fetch('/data/style-library.json')
      .then(res => res.json())
      .then(setLibrary)
      .catch(err => console.error('Failed to load style library', err));
  }, []);

  return library;
}

```

This hook returns the complete library object, allowing child components to destructure specific arrays like `categories` or `templates` without additional network requests.

## Consuming Style Data in Components

Once loaded, the library powers the entire UI generation pipeline. Components extract specific sections to render navigation elements and generate prompts dynamically.

### Rendering Category Lists

The following component demonstrates how the application maps over the `categories` array to build navigation:

```javascript
function CategoryList() {
  const library = useStyleLibrary();

  if (!library) return <p>Loading…</p>;

  return (
    <ul>
      {library.categories.map(cat => (
        <li key={cat.id}>
          <h3>{cat.title.en}</h3>
          <p>{cat.description.en}</p>
        </li>
      ))}
    </ul>
  );
}

```

Each category object contains bilingual titles (`title.en`, `title.zh`), descriptions, and cover image references, enabling localized interfaces without separate translation files.

### Generating Prompts from Templates

When users select specific templates, the application constructs final prompts by concatenating template guidance with associated style and scene keywords:

```javascript
function generatePrompt(templateId, library) {
  const tmpl = library.templates.find(t => t.id === templateId);
  if (!tmpl) return '';

  const tags = tmpl.tags.join(', ');
  const styles = tmpl.styles.join(', ');
  const scenes = tmpl.scenes.join(', ');
  const guidance = tmpl.guidance.en.join(' ');

  return `${guidance} [Tags: ${tags}] [Styles: ${styles}] [Scenes: ${scenes}]`;
}

```

This function demonstrates how the `templates` array connects to the `styles` and `scenes` arrays through ID references, creating cohesive prompt engineering workflows.

## Supporting Files and Build Tools

While [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) serves as the canonical data source, several adjacent files manage and document this content:

- **[`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx)** – The primary React entry point that imports or fetches the library to bootstrap the application state.

- **[`docs/templates.md`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/docs/templates.md)** – Human-readable documentation referenced by the `templateDocument` field in the JSON, providing extended context for template usage.

- **`scripts/generate-style-skill.mjs`** – A Node.js utility script that exports the style library for external consumption, such as CLI tools or third-party integrations.

These files form a complete ecosystem where the JSON acts as the single source of truth, while scripts and documentation provide human interfaces and export capabilities.

## Summary

- **Primary storage:** All GPT-Image2 style data lives in [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) at the repository root.
- **Schema structure:** The JSON contains `version`, `categories`, `styles`, `scenes`, and `templates` keys that define the complete prompt library.
- **Frontend consumption:** [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) and child components fetch this file via standard HTTP requests to populate the React UI dynamically.
- **Prompt generation:** Template objects link to style and scene keywords, allowing runtime construction of GPT-Image2 prompts without hardcoded strings.
- **Maintainability:** Centralizing data in one version-controlled JSON file enables non-developers to edit content without touching JavaScript code.

## Frequently Asked Questions

### How do I update the style library without modifying code?

Simply edit the [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) file in the freestylefly/awesome-gpt-image-2 repository. The React frontend reads this file at runtime, so changes to categories, styles, or templates reflect immediately after deployment without requiring JavaScript rebuilds.

### What happens if the style-library.json file fails to load?

The application implements basic error handling in the fetch logic. If [`data/style-library.json`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/data/style-library.json) is unavailable, the `useStyleLibrary` hook logs the error to the console and returns `null`, causing components to display loading states or fallback UI until the file becomes accessible.

### Can I use this style library in my own project outside of this repository?

Yes. The `scripts/generate-style-skill.mjs` utility script exports the library data for external use. You can also directly import or fetch the JSON from its permanent URL at `https://raw.githubusercontent.com/freestylefly/awesome-gpt-image-2/main/data/style-library.json` to utilize the categories, styles, and templates in custom applications.

### Is the style library data bilingual?

Yes. The `tagLabels`, `categories`, and `template` objects contain both English (`en`) and Chinese (`zh`) properties. This allows the frontend in [`src/main.jsx`](https://github.com/freestylefly/awesome-gpt-image-2/blob/main/src/main.jsx) to render localized interfaces by selecting the appropriate language key from each object.
