# Assets and documents

This guide explains how to work with static assets and generated documents inside the KASKO webapp framework, including how to access them in JsonLogic and content strings.

## Overview

* **Assets** are static files (images, PDFs, etc.) that are attached to items, quotes, policies, offers, or claims.
* **Documents** are generated files produced by backend requests (for example, policy certificates) and may require polling before they are ready.

## Item Assets

Static assets defined at the item/product level:

```typescript
{
  ref: string,    // Reference name (e.g., "logo", "terms_pdf")
  url: string     // Asset URL
}
```

### Accessing Item Assets in JsonLogic

```json
{ "var": "asset.logo" }
```

### Accessing Item Assets in Content

```
{asset.logo}
```

## Generated Documents

Documents are generated after API requests (quote, policy, offer, lead) and may require polling.

### Document Structure

```typescript
{
  name: string,        // Document filename
  extension: string,   // File extension (pdf, etc.)
  url: string,         // Download URL
  designation: string, // Document type identifier
  status: "pending" | "ready"
}
```

### Document Tokens in Content

You can render document links in content using:

```
[{document.policy.certificate.name}]({document.policy.certificate.url})
[{document.lead.offer.name}]({document.lead.offer.url})
```

**Format:**

```
document.{request_type}.{designation}.{property}
```

Examples:

* `document.policy.certificate.url`
* `document.offer.terms.url`
* `document.lead.offer.name`

## Document Polling

For async document generation, use the `poll-documents` component:

```json
{
  "type": "poll-documents",
  "config": {
    "request_type": "policy"  // or "offer"
  }
}
```

The component polls for document status and updates state when documents are ready.

## Policy and Offer Assets

Assets attached to policies or offers after creation:

```typescript
{
  name: string,
  extension: string,
  url: string,
  designation: string,
  attachment_date: string
}
```

### Accessing Policy/Offer Assets in JsonLogic

```json
{ "var": "policy.assets" }
{ "var": "offer.assets" }
```

## Tips

* Use content tokens for links so URLs can be surfaced in translations.
* If documents are not immediately available, include `poll-documents` in your flow and render links after the status is `ready`.
* Prefer `asset.*` for static item assets and `document.*` for generated files.
