# Templates

**Start your projects faster with pre-built templates.**

Templates are ready-to-use website starting points that include complete file structures, styling, and functionality. Use them to skip the initial setup and start customizing right away.

## What Are Templates?

Templates are complete website projects that you can use as starting points:

- **Complete structure** - All HTML, CSS, and JavaScript files
- **Professional design** - Ready-to-use layouts and styling
- **Customizable** - Modify anything to match your needs
- **Learning resources** - Study well-structured code

**Think of templates as:**
- Website blueprints you can build upon
- Starter kits that save time
- Examples of best practices
- Shortcuts to professional results

## Template Types

Each template has a **runtime** that determines how the project is built and previewed. The runtime badge is shown on each template card.

| Runtime | Description |
|---------|-------------|
| **Static** | Pure HTML, CSS, and JavaScript (ES module imports supported) |
| **Handlebars** | HTML, CSS, and JavaScript with Handlebars templating |
| **React** | Component-based React + TypeScript with automatic bundling |
| **Preact** | Lightweight React alternative (~3KB) with signals support |
| **Svelte** | Svelte 5 with compile-time reactivity and runes |
| **Vue** | Vue 3 with Composition API and SFC support |
| **Python** | Python scripts via Pyodide WASM, running in an interactive Console |
| **Lua** | Lua scripts via wasmoon WASM, running in an interactive Console |

Some templates also include **backend features** — edge functions, database schema, server functions, and secrets. These show a "Backend" badge and require Server Mode for full functionality. In Browser Mode, backend templates create the frontend files normally.

## Built-in Templates

### Website Starter (Project)

Minimal starting point with basic structure.

**Includes:**
- Single `index.html`
- Basic CSS file
- Empty JavaScript file
- Clean slate for building

**Best for**: Starting from scratch with minimal setup

- `index.html` shell with bundle references
- `src/main.ts` entry point
- `src/App.svelte` counter component using `$state()` rune

### Landing Page with Contact Form (Backend)

Professional landing page with a working contact form powered by Resend email.

**Includes:**
- Single-page design with contact form
- 2 edge functions (`submit-contact`, `list-messages`)
- Database schema for storing messages
- Optional Resend email integration (requires API key)

**Best for**: Business landing pages, lead capture, contact forms

### Blog with Comments (Backend)

Static blog with user authentication and moderated comments.

**Includes:**
- Static HTML blog posts in `/blog/` directory
- Handlebars partials for navigation, footer, and comments section
- `data.json` post index for the home page
- 6 edge functions (comments, auth: register, login, logout, auth-status)
- Database schema for comments, users, and sessions

**File structure:**
```
/data.json                    — Site metadata + posts array
/index.html                   — Blog home (renders post list via Handlebars)
/blog/hello-world.html        — Static blog post with {{> comments}} partial
/blog/getting-started.html    — Static blog post with {{> comments}} partial
/styles/style.css             — All styles
/scripts/main.js              — Comments + auth JS (no post loading)
/templates/navigation.hbs     — Nav partial (uses {{siteName}}, {{navigation}})
/templates/footer.hbs         — Footer partial
/templates/comments.hbs       — Comments section partial (lazy-loaded)
```

**How it works:**
- Blog posts are individual HTML files — no database needed for content
- The home page uses `{{#each posts}}` from `data.json` to list posts
- Post links like `/blog/hello-world.html` are in static HTML, so the static builder correctly rewrites them for published deployments under `/deployments/{id}/`
- Only comments and auth remain dynamic (edge functions)
- In Browser Mode, comments fall back to localStorage

**Adding new posts:**
1. Create a new HTML file in `/blog/` (e.g., `/blog/my-post.html`)
2. Include `{{> navigation}}`, `{{> comments}}`, and `{{> footer}}` partials
3. Add an entry to the `posts` array in `/data.json`
4. Or just ask the AI to create a new post!

**Best for**: Personal blogs, content sites with community interaction

## Using Templates

### Create Project from Template

1. Click **Projects** in sidebar
2. Click **+ New Project**
3. Select **Use a template**
4. Browse available templates
5. Click on a template to preview
6. Click **Use This Template**
7. Name your project
8. Click **Create**

Your project opens with all template files ready to customize.

**Backend templates in Server Mode:** When you create a project from a backend template, OSW Studio automatically syncs the project to the server, creates a deployment, and provisions all backend features (database tables, edge functions, server functions, secret placeholders). You'll see a summary of what was provisioned.

### Customize the Template

Once your project is created, modify it like any other project:

**Using AI:**
```
Change the color scheme to blue and green
```

```
Replace the hero section with a full-width image banner
```

```
Add a contact form to the contact page
```

**Manually:**
- Edit files directly in the code editor
- Add/remove files as needed
- Update content and styling

## Creating Your Own Templates

Turn any project into a reusable template.

### When to Create Templates

Create templates for:
- Website structures you build often
- Client starter kits
- Personal boilerplate code
- Team standards

### How to Create a Template

1. **Build your project**
   - Create a complete, working website
   - Include all files and assets
   - Test thoroughly

2. **Create a template**
   - Open the project
   - Click **Menu** (⋮) → **Create a Template**
   - Fill in template information:
     - Name
     - Description
     - Category
     - Tags
     - Preview image (optional)
   - The template is saved to your instance's template library

3. **Use your template**
   - Find it in the Templates view
   - Create new projects from it
   - Export to `.oswt` from the Templates view to share with others

###What Makes a Good Template

**✅ Include:**
- Clear, organized file structure
- Commented code for guidance
- Responsive design
- Common pages (home, about, contact)
- Reusable components

**❌ Avoid:**
- Personal/client-specific content
- Hardcoded data that should be dynamic
- Overly complex structures
- Unnecessary files

## Template Tips

**💡 Start with a template**
Even if you'll heavily customize it, starting from a template is faster than from scratch

**💡 Create templates for repetition**
Building similar sites for clients? Create a template once, reuse forever

**💡 Keep templates simple**
Generic templates are more reusable than highly specific ones

**💡 Document your templates**
Add comments in the code explaining sections and how to customize

**💡 Update your templates**
Improve them over time as you learn better patterns

- Some templates include backend features (edge functions, database schema, secrets)
- Backend features are provisioned automatically in Server Mode

**Skills** = Instructions for AI
- Markdown documents
- Teach AI your preferences
- Guide AI's behavior

Use templates to start projects. Use skills to improve how AI builds them.

## Common Questions

**Q: Can I modify templates after creating a project?**
A: Yes! Once you create a project from a template, it's yours to modify completely.

**Q: Do I need to credit template authors?**
A: Check the template's license. Most templates you create are yours to use freely.

**Q: Can I sell websites built from templates?**
A: Built-in templates are yours to use commercially. For imported templates, check their license.

**Q: How many templates can I have?**
A: No limit. Create as many as you need.

**Q: What happens if I use a backend template in Browser Mode?**
A: The frontend files are created normally. Backend features (edge functions, database, etc.) require Server Mode — you'll see a notification about this.

**Q: How do blog posts work in the Blog template?**
A: Blog posts are static HTML files in the `/blog/` directory. The home page lists them from `data.json`. Add new posts by creating HTML files and updating `data.json`, or ask the AI to do it.
