FileFire Document SDK

FileFire is a cross-platform, open-source Document SDK built with Rust, designed for high-performance document processing across mobile, desktop, and web platforms. It follows a Hexagonal Architecture with a Microkernel/Plugin system for maximum extensibility.

🔥 Features

• Cross-Platform: Native bindings for Flutter, iOS, Android, Web (WASM), and .NET
• High Performance: Built with Rust for memory safety and speed
• Plugin Architecture: Extensible microkernel design with hot-swappable plugins
• Document Support: PDF, DOCX, XLSX, PPTX processing and rendering
• Rich Functionality: Annotations, OCR, digital signatures, watermarking, AI-powered features
• Cloud Ready: Headless cloud API for batch processing and SaaS integration

🚀 Quick Start

Flutter

import 'package:filefire/filefire.dart';

final doc = await FileFire.open("document.pdf");
await doc.annotate(page: 1, text: "Hello World", x: 100, y: 200);
await doc.save("output.pdf");

iOS (Swift)

import FileFire

let doc = try await FileFire.open("document.pdf")
try await doc.annotate(page: 1, text: "Hello World", x: 100, y: 200)
try await doc.save("output.pdf")

Web (JavaScript)

import { FileFire } from 'filefire-wasm';

const doc = await FileFire.open("document.pdf");
await doc.annotate({ page: 1, text: "Hello World", x: 100, y: 200 });
await doc.save("output.pdf");

🔧 Building from Source

Prerequisites

• Rust 1.75+
• Flutter 3.0+ (for Flutter bindings)
• Xcode (for iOS bindings)
• Android SDK (for Android bindings)
• .NET 8+ (for .NET bindings)

Build Core Engine

cd core
cargo build --release

Build All Platforms

# Build core and all bindings
make build-all

# Or build specific platforms
make build-flutter
make build-ios
make build-android
make build-wasm
make build-dotnet

🧪 Testing

# Run all tests
cargo test --workspace

# Run platform-specific tests
cd bindings/flutter && flutter test
cd examples/ios_app && xcodebuild test

🌟 Plugin System

FileFire's plugin architecture allows for easy extension:

use filefire_core::Plugin;

#[derive(Debug)]
pub struct OCRPlugin;

impl Plugin for OCRPlugin {
    fn name(&self) -> &str { "ocr" }
    fn version(&self) -> &str { "1.0.0" }
    
    async fn process(&self, input: &[u8]) -> Result<Vec<u8>, Box<dyn std::error::Error>> {
        // OCR implementation
        Ok(vec![])
    }
}

🚀 Roadmap

• Core Rust engine with basic PDF support
• Plugin system architecture
• Flutter bindings and example app
• iOS/Android native bindings
• WebAssembly support
• OCR plugin implementation
• Office document support (DOCX, XLSX, PPTX)
• Cloud API with Docker deployment
• Real-time collaboration features
• AI-powered document analysis
