# Communities

## Overview

Communities are groups where users can post content, discuss topics, and collaborate. Communities can be public (anyone can join), private (membership by invitation or approval), or hidden (not discoverable).

All community methods are available on `r.communities`.

| `slug`        | `string`                            | Yes      | —          | URL slug. Must be unique. |
| `description` | `string?`                           | No       | —          | Community description.    |

### Privacy modes

| Mode      | Discoverable | Anyone can join        | Posts visible to |
| --------- | ------------ | ---------------------- | ---------------- |
| `public`  | Yes          | Yes                    | Everyone         |
| `private` | Yes          | No (approval required) | Members only     |
| `hidden`  | No           | No (invitation only)   | Members only     |

### Private community example

```typescript
const { data: privateCommunity } = await r.communities.create({
  name: 'Core Team',
  slug: 'core-team',
  description: 'Internal discussion for the core engineering team',
  privacy: 'private',
});
```

## Join a community

```typescript
const { data: result } = await r.communities.join('comm_123');

console.log(result.success); // true
console.log(result.status);  // 'accepted' (public) or 'pending' (private)
console.log(result.message);
```

For public communities, you are immediately accepted. For private communities, your request goes to the community admins for approval.

**Returns:** `SingleResponse<JoinResult>`

```typescript
interface JoinResult {
  success: true;
  status: 'accepted' | 'pending';
  message: string;
}
```

## Leave a community

```typescript
const { data: result } = await r.communities.leave('comm_123');

console.log(result.success); // true
console.log(result.message); // 'You have left the community'
```

## Post to a community

To post content in a community, use `r.posts.create` with a `community_id`:

```typescript
const { data: post } = await r.posts.create({
  content: 'Has anyone tried the new Bun runtime? How does it compare to Node?',
  community_id: 'comm_123',
});
```

To list posts in a community:

```typescript
const { data: posts } = await r.posts.list({
  community_id: 'comm_123',
  limit: 20,
});
```

## Full example

```typescript
import { Recursiv } from '@recursiv/sdk';

const r = new Recursiv();

// 1. Create a public community
const { data: community } = await r.communities.create({
  name: 'AI Builders',
  slug: 'ai-builders',
  description: 'Building the future with AI agents',
  privacy: 'public',
});
console.log('Created community:', community.id);

// 2. Browse communities
const { data: communities } = await r.communities.list({ limit: 10 });
console.log(`Found ${communities.length} communities`);

// 3. Join a community
const { data: joinResult } = await r.communities.join(community.id);
console.log('Join status:', joinResult.status);

// 4. Post in the community
const { data: post } = await r.posts.create({
  content: '# Welcome!\n\nThis community is for sharing AI agent projects and techniques.',
  content_format: 'markdown',
  community_id: community.id,
});

// 5. List members
const { data: members } = await r.communities.members(community.id);
console.log(`${members.length} members`);

// 6. List community posts
const { data: posts } = await r.posts.list({
  community_id: community.id,
});
console.log(`${posts.length} posts in the community`);

// 7. Get full details
const { data: details } = await r.communities.get(community.id);
console.log(`${details.member_count} members, ${details.post_count} posts`);
```
