### Prompt Template for LLM App Generation

Source: https://docs.tinykit.studio/no-api-key

Use this template to instruct LLMs like Claude or ChatGPT to generate a tinykit app. Ensure the output is valid JSON matching the specified structure.

```markdown
Create a tinykit app: [DESCRIBE YOUR APP HERE]

Output valid JSON with this exact structure:

```json
{
  "description": "App name",
  "frontend_code": "SVELTE_5_COMPONENT_HERE",
  "design": [],
  "content": [],
  "collections": []
}
```

### Request Flow for Domain Routing

Source: https://docs.tinykit.studio/domain-routing

Illustrates the process Tinykit follows when a request arrives, from domain extraction to serving the correct project.

```text
Request: recipes.yourserver.com/
         │
         ▼
Domain lookup: "recipes.yourserver.com"
         │
         ▼

### Bash Script for Pocketbase Backups via Docker

Source: https://docs.tinykit.studio/security

Automate Pocketbase database backups using a bash script with Docker. This script stops writes, copies the backup, and retains the last 7 days of backups.

```bash
# backup.sh
#!/bin/bash
BACKUP_DIR="/path/to/backups"
CONTAINER="tinykit"
DATE=$(date +%Y%m%d_%H%M%S)

# Stop writes temporarily (optional, for consistency)
docker exec $CONTAINER /app/pocketbase/pocketbase backup

# Copy the backup
docker cp $CONTAINER:/app/pocketbase/pb_data/backups/. $BACKUP_DIR/

# Keep only last 7 days
find $BACKUP_DIR -name "*.zip" -mtime +7 -delete
```

--------------------------------

### Troubleshoot Permission Denied Errors

Source: https://docs.tinykit.studio/vps

{:else}
  {#each items as item (item.id)}
    <div>{item.name}</div>
  {/each}
{/if}
```

--------------------------------

### Manual Database Backup

Source: https://docs.tinykit.studio/vps

Performs a manual backup of the PocketBase database. Optionally stops the application first for consistency, copies the pb_data directory, and then restarts the application.

```bash
# Stop the app (optional, for consistent backup)
pm2 stop tinykit

# Copy database
cp -r pocketbase/pb_data /backup/tinykit-$(date +%Y%m%d)

# Restart
pm2 start tinykit
```

app.yourdomain.com {
    reverse_proxy localhost:3000
}

# Multiple domains for different apps
recipes.yourdomain.com {
    reverse_proxy localhost:3000

  <p>{content.empty_state_message}</p>
{/if}
```

--------------------------------

### Fetch Media URLs

Source: https://docs.tinykit.studio/data-fetching

Use `proxy.url()` to generate accessible URLs for remote media files like audio and images, suitable for use in `src` or `href` attributes.

```svelte
<script>
  import { proxy } from '$tinykit'

  let podcast_url = 'https://example.com/episode.mp3'

```javascript
let count = $state(0)                                      // reactive state
let doubled = $derived(count * 2)                          // simple expressions ONLY
let filtered = $derived.by(() => items.filter(x => x.done)) // use .by() for callbacks/filters
$effect(() => { /* side effects, return cleanup fn */ })
```

--------------------------------

```javascript
let loading = $state(true)
```

--------------------------------

### Create Collection via Code

Source: https://docs.tinykit.studio/database

Create a new collection by adding the first record if the collection does not already exist. The schema is inferred from the record's fields.

```bash
PORT=3000
```

--------------------------------

### Using Text Fields for Titles and Labels

```svelte
<script>
  import data from '$data'

  let title = $state('')
  let saving = $state(false)

  async function add_todo() {
    if (!title.trim() || saving) return

    saving = true
    try {
      await data.todos.create({
        title: title.trim(),
        completed: false,
        created: new Date().toISOString()
      })
      title = ''
    } finally {
      saving = false
    }
  }
</script>

<form onsubmit={(e) => { e.preventDefault(); add_todo() }}>
  <input bind:value={title} placeholder="New todo" />
  <button disabled={saving}>
    {saving ? 'Adding...' : 'Add'}
  </button>
</form>
```
