Pubky App FFI

Cross-platform FFI bindings for the Pubky App, providing native integration for iOS, Android, and Python platforms. This library enables social networking features, user management, content publishing, and data retrieval through the Pubky protocol.

Building the Bindings

All Platforms

./build.sh all

Platform-Specific Builds

iOS Integration

Setup

1. Add the generated XCFramework to your Xcode project:
   • Copy bindings/ios/PubkyApp.xcframework to your project
   • Ensure "Copy items if needed" is checked
   • Add to your target's frameworks
2. Include Swift bindings:
   • Add bindings/ios/pubkyapp.swift to your project

Example Usage

import PubkyApp

class PubkyManager {
    // Create a new user
    func createUser(secretKey: String, homeserver: String) throws {
        let user = PubkyAppUser(
            name: "John Doe",
            bio: "Hello Pubky!",
            image: nil,
            links: [UserLink(title: "Website", url: "https://example.com")],
            status: "Available"
        )
        
        let result = try createUser(
            secretKey: secretKey,
            user: user,
            homeserver: homeserver
        )
        
        if result[0] == "error" {
            throw PubkyError(result[1])
        }
    }
    
    // Create a post
    func createPost(pubky: String) throws {
        let post = PubkyAppPost(
            content: "Hello, Pubky!",
            kind: .Short,
            parent: nil,
            embed: nil,
            attachments: nil
        )
        
        let result = try createPost(pubky: pubky, post: post)
        if result[0] == "error" {
            throw PubkyError(result[1])
        }
    }
}

Android Integration

Setup

1. Add JNI libraries:
   • Copy contents of bindings/android/jniLibs to your project's app/src/main/jniLibs
2. Include Kotlin bindings:
   • Copy bindings/android/pubkyapp.kt to your project's source directory

Example Usage

class PubkyManager {
    init {
        System.loadLibrary("pubkyapp")
    }
    
    suspend fun createUser(secretKey: String, homeserver: String) {
        val user = PubkyAppUser(
            name = "John Doe",
            bio = "Hello Pubky!",
            image = null,
            links = listOf(UserLink("Website", "https://example.com")),
            status = "Available"
        )
        
        val result = createUser(secretKey, user, homeserver)
        if (result[0] == "error") {
            throw PubkyException(result[1])
        }
    }
    
    suspend fun createPost(pubky: String) {
        val post = PubkyAppPost(
            content = "Hello, Pubky!",
            kind = PostKind.Short,
            parent = null,
            embed = null,
            attachments = null
        )
        
        val result = createPost(pubky, post)
        if (result[0] == "error") {
            throw PubkyException(result[1])
        }
    }
}

Python Integration

Setup

1. Install the package:

cd bindings/python
pip install .

Example Usage

from pubkyapp import *

def create_user(secret_key: str, homeserver: str):
    user = PubkyAppUser(
        name="John Doe",
        bio="Hello Pubky!",
        image=None,
        links=[UserLink(title="Website", url="https://example.com")],
        status="Available"
    )
    
    result = create_user(secret_key, user, homeserver)
    if result[0] == "error":
        raise Exception(result[1])
    return result[1]

def create_post(pubky: str):
    post = PubkyAppPost(
        content="Hello, Pubky!",
        kind=PostKind.Short,
        parent=None,
        embed=None,
        attachments=None
    )
    
    result = create_post(pubky, post)
    if result[0] == "error":
        raise Exception(result[1])
    return result[1]

Error Handling

All methods return a Vec<String> where:

• The first element ([0]) is either "success" or "error"
• The second element ([1]) contains either the result data or error message

It's recommended to wrap all calls in try-catch blocks and handle errors appropriately in your application.
