# Share a file’s draft

> Turns the draft’s preview share link on or off.

const site = createSiteClient();
const fileObject = await site.media().shareFile({ id: 'ckitdo5oq004pu69kr6oxo6fr:en:published' });

## In your app

A function makes the call on the client it is given, so your code passes the real one and a test passes a fake.

**1. Add the function**

```ts src/attract/share-file.ts theme={"dark"}
import type { SiteClient } from '@fetchski/attract-cms-sdk';

export async function shareFile(site: SiteClient, id: string) {
  return site.media().shareFile({ id });
}
```

**2. Call it**

A script makes the client once and calls the function:

```ts scripts/share-file.ts theme={"dark"}
import { createSiteClient } from '@fetchski/attract-cms-sdk';
import { shareFile } from '../src/attract/share-file.ts';

const site = createSiteClient();
console.log(await shareFile(site, 'ckitdo5oq004pu69kr6oxo6fr:en:published'));
```

```bash Terminal theme={"dark"}
node --env-file=.env scripts/share-file.ts
```

A route handler, a job or a queue worker calls it the same way.

Takes the draft’s exact `_id` (`…:en:draft`). Answers the draft, with its `aposShareKey` while the link is on: the link is the draft’s `_url` with `aposShareKey` and `aposShareId` (the draft’s `_id`) in its query.

## Find the id

`id` is the document’s `_id`, from a list. Ask the list for only the fields you need: each row is a document’s `id` and those fields.

```ts TypeScript wrap theme={"dark"}
import { createSiteClient } from '@fetchski/attract-cms-sdk';

const site = createSiteClient();
const row = (await site.media().listFilesPick(['title', 'slug'])).find((each) => each.slug === 'getting-started'); // { id, title, slug }, or undefined
```

Pass `row.id` as `id`. Drafts: list with `{ aposMode: 'draft' }` to get the draft’s id ([Find an id](https://docs.fetchski-attract.com/find-an-id.md)).

> [accordion] Required parameters
>
> One object, e.g. `shareFile({ id })`; leave out the optional fields.
>
> **id** `string` *required*
>
> **Required.** Computed document ID (can optionally include mode and locale, e.g., id:en:published) Matches `^\S+$`.

> [accordion] Optional parameters
>
> **share** `boolean | null | undefined`
>
> **Optional.** Leave it out (or pass `null`) and it isn’t sent: the site’s default applies. true adds a share key (`aposShareKey`) to the draft; false (the default) removes it.

> [accordion] Returns
>
> A `FileObject`. Built-in file piece type for general file uploads (PDFs, documents, etc.) Read its properties (`fileObject.id`): each says whether the site always sends it. The example answer is the site’s wire JSON: some keys differ from the property names (`_id` → `id`, `_folder` → `folder`, `_tags` → `tags` …).
>

>
> **visibility** `Visibility`
>
> **Always sent.** Who may see it on the site: `public` (everyone) or `loginRequired` (signed-in people only). One of `public`, `loginRequired`; a newer site may send others, so keep a fallback.

>
> **Sometimes sent:** `undefined` when the site leaves it out. An image’s URLs by size (`original`, `max`, `full`, `two-thirds`, `one-half`, `one-third`, `one-sixth`); unset for other files.

> [accordion] Errors
>
> Nothing to catch: the SDK retries what is safe, and throws the rest as the classes below; catch only what you want to react to (see [Errors and testing](https://docs.fetchski-attract.com/typescript/errors.md)).
>
> **ValidationFailed** `400`
>
> The site refused what was sent: `errors` lists each field’s problem, `siteMessage` the first.
>
> **Retried first:** No. **Read:** `errors` (field → messages), `siteMessage`.
>
> **AuthenticationFailed** `401`
>
> The API key is missing or refused (malformed, revoked, expired), or a signature its signing mode needs is missing or stale.
>
> **Retried first:** No. **Read:** `siteMessage`, `errorName`, `data`.
>
> **Forbidden** `403`
>
> The key may not do this: a scope it lacks, or an address outside its allowlist. `siteMessage` names it.
>
> **Retried first:** No. **Read:** `siteMessage`, `errorName`, `data`.
>
> **NotFound** `404`
>
> Nothing matches, or the caller may not see it.
>
> **Retried first:** No. **Read:** `siteMessage`, `errorName`, `data`.
>
> **SiteError** `500`
>
> The site failed. Its logs say why.
>
> **Retried first:** No: a write may have landed. **Read:** `siteMessage`, `errorName`, `data`.
>
> **SiteUnreachable** `no answer`
>
> No answer: DNS, a refused connection, TLS, or the timeout (15 s per attempt by default).
>
> **Retried first:** Only when nothing reached the site (`neverConnected()`); never after a timeout, when it may have landed. **Read:** `reason`, `neverConnected`.
>
> **RequestNotSent** `not sent`
>
> The client refused to send it (e.g. a path segment of `..`); the site never saw it.
>
> **Retried first:** No. **Read:** `reason` (what to change).
>
> **SiteRequestFailed** `any other`
>
> Any other status, or a success whose JSON doesn’t match this SDK version’s types (update the SDK).
>
> **Retried first:** No. **Read:** `reason`, `status`.
>
> **UnknownSite** `setup`
>
> `sites.forSite('acme')` named a slug your sites (`createSiteClients()`) don’t have.
>
> **Retried first:** No: nothing was sent. **Read:** `message`, `slug`.
>
> **SiteConfigurationError** `setup`
>
> The client’s settings are wrong: no `FETCHSKI_ATTRACT_URL` (or `baseUrl`), or a malformed API key.
>
> **Retried first:** No: nothing was sent. **Read:** `message` (what to fix).

## Behavior

* **Access:** an API key with `content:files:write` (or a master above it: `content:files:all`, `content:all`, `admin:all`). A signed-in person may call it as far as their own permissions allow; anyone else gets 403.
* **Rate limit:** the key’s own writes-per-minute limit, set when the key is created (default 120); over it, 429 with `Retry-After`. The client waits and retries for you; you see `RateLimited` only if that runs out.
* **Retries:** a write is sent again only after a 429 (refused before it acted) or when it never reached the site. After a timeout or a 5xx it may have landed: check before you send it again.
* **Timeout:** 15 s per attempt by default; raise `timeout` (milliseconds) on the client for longer.

## Test it

It calls the function above with a fake client: the fake answers every call with a valid example, so nothing leaves your machine and no settings or key are needed. Run it with `node --test`.

```ts tests/media-shareFile.test.ts theme={"dark"}
import { test } from 'node:test';
import { fakeSite } from '@fetchski/attract-cms-sdk/testing';
import { shareFile } from '../src/attract/share-file.ts';

test('media.shareFile', async () => {
  const site = fakeSite();
  await shareFile(site, 'ckitdo5oq004pu69kr6oxo6fr:en:published');
  site.assertCalled('media.shareFile', (args) => args.id === 'ckitdo5oq004pu69kr6oxo6fr:en:published');
});
```

**Answer with your own values:** fake `media.shareFile` with `factories.FileObject({...})`, the fields you give over a valid example.

```ts tests/media-shareFile-answer.test.ts theme={"dark"}
import assert from 'node:assert/strict';
import { test } from 'node:test';
import { factories, fakeSite } from '@fetchski/attract-cms-sdk/testing';

test('media.shareFile answers your values', async () => {
  const site = fakeSite({
    'media.shareFile': factories.FileObject({ id: 'Your value' })
  });
  const fileObject = await site.media().shareFile({ id: 'ckitdo5oq004pu69kr6oxo6fr:en:published' });
  assert.equal(fileObject.id, 'Your value');
});
```
